Planting method of Dichondra repens value of Dichondra repens

Dichondra przewalskii has green leaves, low plants, dense and beautiful leaves, and is deeply loved by people. The editor of the decoration network reminds you that when planting Dichondra, you must first master some relevant knowledge. Here, we will learn more about it with the editor of the decoration network.

Planting method of Dichondra repens value of Dichondra repens

The planting method of Dichondra repens

1. Soil preparation: loosen, rake and refine the ground so that the diameter of soil particles is less than 2cm. Adjust the soil pH to 5.5-7.0. Disinfect the soil with formalin: water = 1:40, the dosage is 1015L per square meter of bed. The soil needs to be dry before disinfection.

2. Trenching and transplanting: make a deep trench of 2~3cm on the prepared turf bed, and the distance between the trench and 3~4cm. Separate the prepared Dichondra plants and place them evenly in the ditch, keep the plant spacing 3~4cm, cover with soil 2cm, water once, cover with sunshade net or grass curtain, and keep the soil moist every day. On the 5th day of planting, the plant grew vigorously, but the stolons did not fully contact the ground and grow new roots; on the 10th day, a large number of stolons in full contact with the ground will grow new roots and buds.

3. Cultivation covered with fine sand: before planting, the prepared turf was watered thoroughly, the turf of Dichondra repens was torn off manually and spread evenly on the bed, and the prepared fine sand was evenly scattered on the top of Dichondra repens. The sand 6~10mm was thick, keeping the fine sand completely moist, and covered with sunshade net to prevent excessive evaporation of water. By the 5th day, a large number of new roots had grown on the stolon nodes of Dichondra repens, and on the 10th day, a large number of new branches had grown in the place where the new roots were born.

4. Fertilization: due to the creeping growth of Dichondra repens on the ground, and the leaves are relatively broad, fertilization is very difficult. If we do not strictly grasp the fertilization technology, it will cause serious seedling burning. Generally speaking, if you use fertilizers with high solubility, it is best to dissolve them first and then spray them with a sprayer; if you use fertilizers that cannot be dissolved immediately, you should pour a lot of water after fertilizing, flushing the fertilizers that fall on the leaves into the soil and dissolving them as soon as possible, so as to reduce the degree of burns; or apply fertilizer first, then sweep the fertilizer under the leaves with a broom, and then combine with watering. At the same time, high temperature fertilization should be avoided.

Like nitrogen fertilizer, usually combined with rain and watering, should apply appropriate amount of nitrogen fertilizer, it is best to apply urea 3~5kg/ mu plus diammonium 5~10kg/ mu. After 2 or 3 years of turf cultivation, due to the dense rhizome, it is easy to cause soil consolidation to affect air permeability and water seepage. Piercing can be carried out according to the situation, or a knife can be used to cut off the grass root to improve the looseness of the soil, and nitrogen fertilizer and proper watering should be added at the same time to restore the vitality of the lawn.

5. Weed control: the number of weeds in Dichondra repens lawn is less than that in Dichondra, Manila and tall fescue lawn. This phenomenon is due to the strong creeping nature of Dichondra lawn. On the other hand, it is because of the long green period, anti-green and strong competitiveness of weeds. However, in the newly planted Dichondra lawn, it takes 2-3 months to fully cover the ground, so it is easy to be invaded by weeds before it is fully covered. Artificial extraction can be used when there are few weeds, and herbicides can be used if there are more weeds. Spraying green bacteria SL- 2 compound 525-675g/hm2 at one time could control the harm of most weeds and lasted for 80-90 days, and it was safe to Dichondra repens lawn. It is worth noting that herbicides are best used in weed seedling stage.

The Medicinal value of Dichondra repens

The function of Dichondra repens is mainly for jaundice; dysentery; sand gonorrhea; white turbidity; edema; eczema; fall injury; venomous snake bite. Clearing heat and promoting dampness, detoxification and detumescence. For hepatitis, cholecystitis, dysentery, nephritis edema, urinary tract infection, urinary calculi, tonsillitis, fall injury, slightly bitter, sweet, cold. Enter the water, wind tower.

It can protect liver and lower enzyme, analgesia, anti-inflammation, antibacterial, antipyretic and cholagogic, enhance immunity and anticancer effect. As an adjunct to other drugs, Dichondra can treat "cattle", "Mengsha Hei", "answer from ear to ear", "bury people from ear to ear", and "say Feng Linglan" (these are all Miao languages, and the editor really doesn't understand the meaning. I can only ask my friends to search the Internet).

When taking it, you can take it internally, fry soup, take an appropriate amount of tamping and apply it to the affected area.

Lawn Ning has good safety effect in removing weeds in cedar garden lawn.

The diversity and layout of cedar garden plants make it difficult to weed the lawn. In order to clarify the weed control effect and environmental safety of cedar garden lawn, under the guidance of experts, the lawn test of more than 200000 square meters showed that lawn Ning was effective in controlling weeds in cedar garden lawn.

"prescribing the right medicine to the case" is the premise.

Southern cedar garden lawn is mainly warm season grass such as Zoysia, Bermuda, seashore paspalum and so on. The main weeds are coriander, three-point gold, water centipede, aconite and horse tang, supplemented by corymbaria, sorrel, snow grass, plough grass, Niuteng grass, millet and so on. There are many kinds of herbicides in lawn, including pre-bud, post-seedling, pre-bud and post-seedling. Some weeds, and some weeds. The medicament should be selected according to the weed species, weed growth period, management level and lawn species, and the high safety factor of lawn should also be considered. Warm season grass has strong drug resistance, but some grasses should be careful, such as big-leaf oil grass and horseshoe grass and so on.

"seizing the opportunity" is the guarantee

The proper use of medicine is the guarantee of success. The use of pre-bud herbicides before germination of weeds in lawn growth period is an efficient, labor-saving and money-saving method. If the germination period is missed, the pesticide can also be applied early after the seedling, and the stubborn perennial weeds such as sorghum should be applied during the transition period from vegetative growth to reproductive growth, which can be eradicated. In order to control the weeds of Zoysia grass in the football field, such as copper coin, brocade, corymbaria and other weeds, during the lawn growth period in August, the weeds were sprayed with lawn Ning 1 + 38 + 42 before germination with a mixture of 16 kg of water and 150 square meters of water. The effect is more than 95%. Similar seedlings have different treatment and repair methods for weeping willows. In November, weeds enter the flowering stage, when the same amount of medicine can only be sprayed 100 square meters, the effect is only 90%, and the cost is doubled. Therefore, lawn weeding should seize the good opportunity of spring or late spring and early summer.

"gradual and orderly progress" is fundamental.

First experiment, then demonstration and expansion is the foundation to achieve the success of lawn weeding. The weeding of cedar garden lawn should not only be eradicated efficiently, but also prevent the hidden drug damage to the lawn, and not hurt flowers and shrubs at the same time. We first draw a lawn, the weed coverage is about 90%, the weeds are mainly coriander, water centipede and aconite, cut the grass first, clear the grass shavings, spray 150m2 with lawn Ning 1 + 38 + 42 each mixed with 16kg of water, spray water (it is suitable to sprinkle water after fertilization), temperature 30 ℃, weed leaves turn yellow 7 days after spraying, weed roots rot 21 days, the control effect is more than 95%. The popularization and application of lawn weeding in a large area has solved the difficult problem in the management of cedar garden lawn.

"adapting measures to local conditions" is the foundation.

In the practice of lawn weeding, special application methods should be used in special areas. There are many slopes in the garden, which are covered with lawns and are often surrounded by flowers or shrubs. If you spray according to the conventional spray, due to the leaching of the soil and the horizontal movement of herbicides, the roots of flowers and trees under the slope are vulnerable to chronic damage by herbicides. In this area, weeding is generally not used before budding, but after seedlings. In sunny or cloudy days (preferably to avoid rain within 48 hours), spray thoroughly, so that the agent can be sprayed on the stems, leaves and base of weeds as far as possible. In an experiment, there was a yellow leaf of Forsythia suspensa under the lawn slope, and the root withered, which was found to be drug damage: when spraying water before the bud, the liquid flowed down with the slope, and the liquid invaded the root of Forsythia suspensa, causing its root damage. Results the following remedial measures were taken: ① increased the amount of water to spray the damaged flowers and trees. ② sprayed the damaged flowers and trees with foliar agents such as 0.4% potassium dihydrogen phosphate or Gaomeshi 500x solution, used in rotation for 3 times in a row, once every 7 days. If the pre-bud medicine needs to be sprayed with water, increase the amount of water instead of water. The knapsack sprayer with smaller droplets is chosen instead of the high-pressure gasoline sprayer, because of its large droplets and wide spray range, it is easy to damage garden plants. In order to avoid damage to the flowers and trees around the lawn, keep a safe distance from the cedar garden plants (calculated from the stem of the plant): the root plants (such as palms and willows) are more than 1 meter, and the straight-root plants (such as Masson pine and camphor trees) are more than half a meter. If there is a strong wind or there is no wind to spray on the edge of the flower bed, add a protective shield on the sprinkler (the simple way is to make a hole in the bottom of the instant noodle cup and put the cup mouth down on the sprinkler) to prevent the liquid from drifting.

"Ecological control" is the direction

In order to reduce the dependence on herbicides, we also adopted the comprehensive management of weeds through plant quarantine to eliminate weed seeds, appropriate low shearing, reduced fertilization, drilling and sand laying, grass thinning and artificial weeding. As a result, the competitiveness of lawn to weeds can be improved, and the harm of weeds can be controlled by strong lawn and excellent ecological environment. Because the lawn is a slightly toxic and environment-friendly agent, it can be used in lawns where it is impossible to pull grass manually. On the other hand, in the lawn where weeds are removed successfully, we should strengthen the management of the lawn to make the lawn grow stronger, in order to restrain the germination of weeds and put an end to the space for weed reproduction.
