How to breed, how to breed, how to

Lobular Ligustrum lucidum is a common flower plant in people's life, which has high ornamental value. There are many people who breed it everywhere, but as more people breed it, people are more concerned about its reproduction. How to reproduce lobular privet? What are the ways of reproduction of lobular privet? Next, the editor will take you to learn about it.

First, how to propagate lobular privet, sowing / cutting / ramet

When it comes to how to reproduce lobular privet, it is mainly divided into three methods: sowing reproduction, cutting propagation and ramet reproduction. As long as they are operated properly, the survival rate of the three reproduction methods is very high. As for how to operate these three reproduction methods, there is a detailed introduction below, let's take a look at it.

Second, the reproduction mode of lobular privet.

Matrix selection

Whether it is sowing propagation, cutting propagation or plant propagation, we first need to choose the substrate, which is a step to lay a good foundation and is very important. Generally speaking, it is best to choose loose and fertile sandy soil. This kind of soil has good drainage and air permeability, which can make plants better absorb nutrients and is not prone to the phenomenon of stagnant water.

Sowing and reproduction

Seed reminder: before we sow and reproduce the lobular privet, it is best to soak the seed in warm water for 1-2 days, which can promote the seed, wait until the seed begins to absorb water and swell, and then rub with both hands to remove a layer of purple-black skin from the outside of the seed.

Sowing method: before sowing, we should first apply an appropriate amount of base fertilizer to the soil, then sow the seeds evenly on the soil surface, and after sowing, cover the soil with 1-2cm to water, because the seeds of Ligustrum lucidum are relatively small, so we had better use the soaking pot method to water the seeds, so as to prevent the seeds from being washed away, put the flowerpot into the water for 1/2, and let the water soak up slowly.

Cuttage propagation

Cuttings selection: when selecting cuttings, it is generally best to choose branches that are relatively robust and disease-free as cuttings, so that the survival rate will be very high, if you choose branches that look very small and delicate, then you can basically declare that the cuttage failed, and the survival rate will not be very high.

Cutting method: in the propagation mode of lobular privet, cutting propagation is a relatively simple one. Before cutting, we can first use chopsticks to cut a hole in the basin soil, and then insert the cuttings into it. This operation can avoid damage to the cuttings, is very practical, and then placed in a shady place for about a week can be moved to outdoor breeding.

Ramet propagation

When we propagate the lobular privet, we can combine it with changing pots, and the time can be chosen in spring and autumn. When ramet, we should pull out the overgrown mother plant from the basin soil, then cut it into several clumps, put it on the basin separately, and plant it along with it, which is very easy to survive. It is usually a complete pot of flowers after it is put on the pot.

Propagation methods and key points of cultivation and management of lobular privet

Recently, many seedling farmers and flower farmers have asked about the sowing methods of lobular privet and the prevention and treatment of lobular privet diseases. The editor of Huinong Network has summarized all these questions for everyone.

I. the mode of reproduction

It is often propagated by sowing, cutting and ramet.

(1) sowing and reproduction

The sowing and reproduction of Ligustrum lucidum can be divided into seed collection and processing, nursery arrangement, sowing and other steps.

1. Collection and treatment of seeds

Collection of ① seeds. The ear is cut with branches and accumulated in a cool place, and the pulp is removed after rotten to get a net seed.

The treatment of ② seeds. The net seeds obtained are dried and put into a cloth bag for dry storage, or low temperature stratification can be carried out directly to accelerate germination. Low-temperature stratification method: spread a layer of 10 cm thick wet river sand on the indoor ground (the humidity of the river sand should be held by hand and loose), accumulate seeds and river sand layer by layer according to the ratio of 1: 2, the height is not more than 30 cm, the top layer is covered with a layer of 10 cm thick river sand, and insert several bamboo tubes with holes for air permeability; check the seeds frequently, change the sand when the river sand is too wet, and spray water properly when it is too dry.

two。 Nursery land arrangement

The slightly acidic soil with fertile soil, convenient transportation and water source was selected as the nursery.

① nursery arrangement. The nursery will be ploughed once at the end of autumn and the beginning of winter, with a depth of 35 cm without raking. Freezing in winter can improve soil physical and chemical properties, promote soil weathering and reduce diseases and insect pests. Winter can be combined with rural winter leisure, rich labor and other conditions, dig a good nursery around the drainage ditch (ditch), the standard is 40 cm wide, 35 cm deep. In the middle and last ten days of February, 2000 kg of fully mature barnyard manure, 200kg of rotten cake fertilizer, or 80kg of potassium sulfate compound fertilizer (15-15-15) were applied per mu. The above three fertilizers could be combined with calcium superphosphate 75 ~ 100kg to promote the growth of seedlings. After fertilization, the soil was raked continuously for 3 ~ 4 times, so that the nursery land was raked flat, the soil was raked and the fertilizer was evenly mixed in the soil.

② trenches to make a bed. Hit the bed according to 1.5 meters wide, in which the width of the box is 1.2 meters, the width of the groove is 0.3 meters, and the depth of the groove is 0.25 meters. In order to avoid sunburn seedlings, the seedling bed is mostly in the north-south direction, the length is controlled within 20 meters, and the waist (middle) trench should be opened if it is too long, so that the "three grooves" of perimeter trench, waist (middle) trench and chamber trench are connected, so as to facilitate drainage and irrigation and personnel operation. Spread the soil in the ditch evenly on the surface of the bed to increase the fertilizer layer.

③ sterilization and insecticide. In order to prevent the outbreak of diseases and insect pests in the nursery, it should be sterilized and insecticidal once before sowing. 70% sodium sulfonate wettable powder 1 ~ 1.5 kg mixed with fine soil 10 kg / mu was used to prevent diseases, and 3% carbofuran granules 3 ~ 5 kg / mu was directly applied to prevent insect pests.

3. Sowing seeds

At the beginning of March, the seeds stored in dry storage were taken out, and the seeds germinated by low temperature stratification were screened out by sieving. Both of them need to be carefully selected to remove mildew seeds and get net seeds. Dried seeds: first soak in warm water for 24 hours, change the water every 12 hours, and finally soak the seeds with 0.1% potassium permanganate solution for 30 minutes, wash and drain before sowing the seeds. Seeds germinated by low temperature stratification: wash and drain and then direct seeding.

First open a sowing ditch, in which the furrow distance is 30 cm and the groove depth is 2 cm. The seeds accelerated by dry storage and low temperature stratification should be sown separately. When sowing, sow the seeds evenly in the ditch according to 0.5 cm spacing, cover the fine soil 2 cm thick after sowing, pour water with a spray pot, and then cover pine needles, straw, sawdust, etc., in order to preserve moisture and air. After the seedlings of Ligustrum lucidum were unearthed, the mulches such as pine needles and straws were removed in batches, and 1000 times of carbendazim wettable powder and 2500 times of deltamethrin EC were sprayed to control insects.

Through the experiment, the seeds of lobular privet germinated by low temperature stratification emerged early and neatly, which was better than that of dry storage.

(2) Cuttage propagation

Lobular privet cutting can be divided into hardwood cuttage and tender wood cuttage.

1. Hardwood cuttage

Hardwood cutting refers to cutting with one-to two-year-old lignified branches in February to March, including nursery site preparation, cutting, post-cutting management and so on.

① nursery preparation. a. Prepare the ground. The method of soil preparation is the same as that of the nursery with sowing and breeding method.

b. Open trenches to make beds. The cuttage nursery is 1 meter wide, 0.3 meters wide and 0.25 meters deep, and the length is controlled within 20 meters. The soil on the seedling bed will be further crushed to make the tortoise back shape slightly higher in the middle and slightly lower around to prevent stagnant water. Set up a shade shed according to the cutting area in spring, cover 50% of the shade net on the shade cloth, and the shade net must be connected with a strong rope or wire, flush with the ground around the net to prevent the sun from shining directly on the seedling bed. The shade must be strong enough to withstand the strong wind.

c. Sterilization. 24 hours before cutting, water the seedbed with 0.1% potassium permanganate solution.

② cuttings. Can be combined with spring shaping and pruning, cut the one-to two-year-old ligneous outer branches of lobular privet and put them in a cool place in the leeward. Cutting at the same time, it is required in principle to finish cutting on the same day. Cut the branches into 12 ~ 15 cm, with 2 ~ 3 buds or leaves, remove the lower leaves and retain the upper leaves; the upper flat cut, the lower oblique cut; 50 are tied up. With 0.2% IBA (indolebutyric acid) solution quickly dipped in the base for 5-10 seconds, after a little drain, the cutting depth is more than 2 IBA 3 of the cuttage length.

③ plug-in management. After the cuttage is finished, quickly pour through the water, then spray with 1000 times of thiophanate methyl, and then keep the soil suitable humidity according to the weather conditions, and it can heal and take root in about 30 days. During this period, it is necessary to strengthen the management of diseases and insect pests, pull out the rotten cuttings and burn or bury them at intervals of about 10 days, and spray the whole field with 1000 times of carbendazim wettable powder. The sunshade net can be removed two weeks after it is fully rooted.

two。 Tender wood cuttage

Softwood cutting refers to the use of semi-lignified branches in May ~ July or September. Twigs have the characteristics of sufficient vitality, exuberant cell division and easy to take root.

① nursery preparation. Preparation of the nursery with hardwood cuttings. Due to the strong sun and high temperature in summer and autumn, it is necessary to use about 90% of the sunshade net; there are many strong winds and torrential rains in summer, the shade shed must be firmly built, wooden piles should be built around, and the sunshade net should be fixed with wire.

Nutrition management of ② ear-picking garden. At ordinary times, it is necessary to strengthen the nutrition management of the ear-picking orchard. 10 days before ear-picking, the foliar spray was carried out with 0.2% ~ 0.3% potassium dihydrogen phosphate + 68.75% oxone ·manganese zinc 1200 times, and then sprayed once after 5 days, and should be watered once in case of dry weather. in this way, the cultivated spike garden of Ligustrum lucidum has full branch vitality, strong vitality and less diseases and insect pests.

③ cuttings. Ear picking should be carried out before sunrise. Place the collected branches indoors and often spray water to moisturize to prevent dehydration. Cut the branches indoors into 8 cm and 10 cm long. When cutting short, remove the tender part of the tip, leaving 2 leaves and 50 roots as a bundle. The lower part was quickly dipped in ABT rooting powder or IBA (indolebutyric acid) 1000 times solution, after a little dry, it can be cut. Before cutting, punch holes in the cutter with a stick of the same thickness as the cuttings, put the cuttings into the holes, and press them with your hands. After the cuttings are finished, water the cuttings quickly and spray them with 1000 times carbendazim wettable powder. A "ten" frame is built at each end of the inserting machine, and a small arch shed is built with bamboo slices 2 meters long and 2 centimeters wide, fully covered with a 2-meter-wide media, pressed with stones, and then covered with a 50% sunshade net close to the film.

④ plug-in management. It is mainly the management of the temperature and humidity in the small arch shed. Within 30 days after cutting, the air relative humidity in the small arch shed should be kept above 90%, the soil water content should be about 60% of the saturated water content, and the temperature should be controlled below 38 ℃. To reduce transpiration, foliar spray can be used to increase the relative humidity of the air. When the lobular privet begins to take root, it can be properly ventilated to reduce soil water content. When the leaflet privet is fully rooted and 50% of the leaves begin to sprout, it is necessary to refine the seedlings: first open one end of the small arch shed, and then uncover the other after 3-5 days; after 3-5 days, remove the film and 50% of the shading net on the small arch shed, and remove 90% of the shading net on the shade after two weeks. During this period, the rotten and dead cuttings were pulled out and burned or buried every 10 days, and the whole field was sprayed and sterilized with 1000 times of methyl thiophanate wettable powder. Transplant cuttings into the field in winter or spring.

(3) ramet propagation

The leaflet privet plants with vigorous growth and more root tillers were selected in spring, cut and planted from the roots, and watered after planting, which could develop into independent plants.

II. Seedling stage management

1. Interseedling, supplementary seedling

The seedlings between sowing seedlings can be divided into two stages: the first time, when the seedlings are 5 ~ 10 cm high, the seedlings are replenished with interseedlings, and the seedlings with persistent soil are gently dug up with a small pointed shovel, and then replanted in sparse places (or find another field for planting). The original seedling field and transplanting field should be watered firmly; the second time is fixed seedling, the time is about 15 days after the first seedling. The seedlings should follow the principle of "keeping large, dense and sparse, inferior and superior, and keeping equal distance".

two。 Loosen the soil and weed

Loosening soil and weeding should be carried out when irrigation or operation can be carried out after rain. The thickness of loose soil should be shallower than the thickness of covering soil, and hoes and shovels can be used to loosen the soil and make the soil loose and breathable. Small pointed shovels are used to remove weeds in the cutting seedling field, and the loose seedlings are watered firmly. Weeding is done once a month from May to July and once a month from August to September to reduce weeds and seedlings for glory, water and fertilizer, so as to promote the healthy growth of seedlings.

3. Water and fertilizer management

Rational irrigation is the premise to promote the normal growth and development of seedlings. Before and after the emergence of spring sowing seedlings, according to the weather conditions, irrigation should be taken a small number of times, sometimes dry and sometimes wet; attention should be paid to clearing ditches and desilting in plum rain season; irrigation times should be increased and fully watered in summer drought; less watering in autumn; no watering in winter. From June to August, topdressing can be carried out in combination with watering: for sowing seedlings, 5 ~ 10 kg urea per mu is applied, while watering and dissolving and cleaning, so as to avoid burning seedlings and causing fertilizer damage; for cutting seedlings, 0.2% ~ 0.3% potassium dihydrogen phosphate solution is sprayed on the leaves; the two topdressing methods are applied once every 15 days, and continuous topdressing for 2 ~ 3 times, which can effectively promote seedling growth. After August 15, stop topdressing urea and apply a small amount of phosphorus and potassium fertilizer to promote the Lignification of seedlings and survive the winter safely.

4. Pest control

The main diseases of lobular privet are anthracnose, leaf spot, powdery mildew, etc., which can be sprayed with 65% Dessen zinc wettable powder 800 times. Pests include aphids, ground tigers, etc., which can be killed by spraying 1000 times of 90% crystal trichlorfon or 2500 times of 2.5% deltamethrin EC.

III. Cultivation and management

The transplanting of Ligustrum lucidum is carried out in late winter and early spring. In addition to conventional water and fertilizer management and mid-ploughing, different management measures are mainly taken according to different cultivation purposes: if hedgerow seedlings are cultivated, they can be managed extensively; if the seedlings are mainly cultivated, transplanting should be carried out after seedling cultivation, and the upper part should be trimmed and cultivated horizontally and trimmed into plump balls. If you want to cultivate into a wavy shape, it should be trimmed according to the high and low position to form a wavy whole.

The reproduction method of planting lobular privet is very important, if you want to know more about the planting techniques related to lobular privet, please continue to pay attention to Huinong net!

Explain in detail the planting techniques of lobular privet.

Lobular Ligustrum lucidum belongs to small shrubs, which are very common in people's birthday life. the oval shrubs are the form of lobular privet. There are lobular privet in the city, by the river and in the community. They play an important role in people's urban tourism. But how many people know about the planting technology of lobular privet? It doesn't matter what you don't know. Today, the editor will explain the planting techniques of lobular privet in detail.

Ligustrum lucidum is a small shrub of Oleaceae and Ligustrum lucidum. Its leaves are very thin and a little small, so it is called lobular Ligustrum lucidum. Today, we will explain the planting techniques of lobular privet mainly from four aspects: growth habits, breeding methods, cultivation techniques and prevention of diseases and insect pests.

Growth habits of planting techniques of lobular privet

Lobular privet likes light and is relatively hardy, which makes it possible for open-air cultivation in North China, and it is also a shrub suitable for planting in North China. The germination ability of lobular privet is very strong, which creates the fast growth rate and strong pruning resistance of lobular privet. In addition, Ligustrum lucidum has obvious resistance to toxic gases such as sulfur dioxide and chlorine dioxide.

Propagation mode of planting technique of lobular privet

The reproduction mode of lobular privet is the same as that of other shrubs, which can be divided into three ways: sowing, cutting and dividing plants. for sowing reproduction, we should pay attention to the fruits of lobular privet from October to November on the mobile phone, sowing in May, and the time is not easy to be confused. For cutting propagation, it is most suitable in spring. We should not only pay attention to the cutting branches to meet the growth of more than two years, but also pay attention to the new branches that must be newly grown. For ramet reproduction, it is relatively simple, as long as in the spring and autumn, multiple lobular privet plants will be planted separately.

Cultivation techniques of planting techniques of lobular privet

The cultivation and reproduction techniques of lobular privet are different, which are mainly reflected in three aspects: subordination, transplantation and pruning. Sub-subordinate means that the lobular privet grows too luxuriantly. In order to better make it grow, the branches that are too luxuriant are separated from the roots and replanted. Transplantation refers to the cultivation and planting of lobular privet from one place to another. Pruning is much easier, that is, the maintenance of lobular privet.

Prevention of Diseases and pests in planting techniques of Ligustrum lucidum

There are not many natural enemies of Ligustrum lucidum, and the main pests are longicorn beetles. The easiest way is to bury 3-4 camphor balls in the place where lobular privet is planted, which is a deadly weapon for longicorn beetles. If there are too many diseases and insects, dichlorvos can be sprayed on the wormholes of longicorn beetles in spring to kill insects effectively.

To sum up, it is the detailed introduction of the planting technology of lobular privet prepared by the editor today. Do you understand it? I hope that through the introduction of the editor, we can let everyone have a certain understanding of lobular privet.
