First, how to raise passionflower and understand its habits

Indoor passionflower culture is not as good as outdoor, light, water and so on need us to create, so how to cultivate passionflower, first understand its growth habits, and then meet its normal growth. In this regard, the editor will bring you very detailed passionflower planting techniques from the methods of soil, light, water and fertilizer, and we will move on.

II. Passionflower planting techniques

1. Soil

If you want to keep passionflower at home, you must first choose the soil it likes. It is understood that passionflower has a good adaptability and does not have high requirements for soil, but general soil is fine. But if you want passionflower to grow well, you'd better prepare soil that is deep, rich in humus, loose and well drained.

2. Lighting

In passionflower planting technology, light is extremely important. Because passionflower is a tropical and subtropical plant, it likes light and warm environment. When raising at home, it is best to put it on the balcony and the sunny place of the courtyard lamp. On a cloudy day, you can move to the windowsill facing south to maintain.

3. Watering

How to raise passionflower, there is an indispensable link, that is watering. Passionflower likes to be wet and is not resistant to waterlogging, so it has a high demand for moisture, and it is not good to water too much and less. Therefore, in the maintenance process, we need to strictly grasp the frequency and amount of watering.

In this regard, in the passionflower planting technology, the requirements for watering are as follows: in summer, the soil should be watered in time when the soil is dry; in the rainy season, when there is too much water in the soil, we should pay attention to timely drainage to ensure that the soil does not turn white. In addition, when passionflower blossoms and bears fruit, the soil water content should be kept to the maximum, otherwise it will lead to fruit size, quality decline and fruit drop.

4. Fertilization

After watering, let's take a look at fertilization, which also plays a vital role in the growth of passionflower. Passionflower will blossom and bear fruit, so proper fertilization is necessary, and it is best to apply thin fertilizer frequently: increase the application of rotten organic fertilizer during the growing period, increase the application of urea at the flowering stage, and increase the application of cake fertilizer at the fruit stage.

Note: in order to make passionflower blossom and bear more fruit, proper fertilization is very necessary, but pay attention to the application of nitrogen fertilizer as little as possible, otherwise it will easily lead to the phenomenon of passionflower overgrowth.

5. Pruning

If you want to raise passionflower well, in addition to the above, you should also pay attention to pruning. When the passionflower has luxuriant branches, it needs to be pruned, and some sterile branches or old branches should be pruned in time; in addition, some overgrown branches, over-dense branches, or disease and insect branches are all trimmed, which is beneficial to the healthy growth of passionflower.

Picture: passion fruit

1. Soil: passion fruit has strong adaptability and low requirements for soil. Flat or sloping land with good drainage and irrigation, such as sandy loam, red loam and kaolin, can be planted, and must not be planted in long-term low-lying water accumulation areas. In large-scale production, it is best to grow in places with fertile soil, loose soil and good drainage, and paddy fields that can be drained and irrigated are the best. The most suitable soil pH for fragrant fruit is 5.56.5.

2. Planting: passion fruit is produced in the same year when it is planted, and it is suitable to be planted from February to March each year. The passion fruit planted is a vine fruit tree with extended branches and vines, so it is appropriate for scaffolding cultivation to have a row spacing of 3 meters and a plant spacing of 3-3.5 meters. In general, the economic cultivation life of passion fruit is 4-5 years, and the old plant will be cut down and renewed comprehensively after harvest in the fifth year. Because passion fruit is a tropical fruit, continuous stubble is easy to be infected by virus, which reduces the yield and quality. in order to reduce virus infection, virus-free healthy seedlings are the best to be replanted every year. Planting method according to the scheduled row spacing, dig 60 cm wide, 20-30 cm deep planting ditch, first put in the mixed compost or other soil and miscellaneous fertilizer, at the same time, add 0.25 kg phosphorus + 0.15-0.25 kg compound fertilizer, and then plant from the pier. After planting and survival, the axillary buds should be removed at any time, leaving only the terminal buds of the main vine, and the vines should be tied to the pillar so that the plants can climb onto the scaffolding as soon as possible.

3. Setting up scaffolding: scaffolding must be set up during passion fruit cultivation for management and harvest. There are many forms of scaffolding, which are mainly horizontal scaffolding and single-line hedge scaffolding. The single-line fence column is 2.3 meters high and is erected between plants. It is implanted into the ground about 30 centimeters, and each column pulls 2 No. 12 lines.

4. Water management: passion fruit is more tolerant to drought, but it still needs irrigation in case of drought. If the soil is too dry, it will affect the development of vines and fruits, and in serious cases, the branches will wither, the fruits will not develop and the fruit will drop. Remove stagnant water in time during the rainy season.

5. Light: passion fruit likes plenty of sunlight to promote vine growth and nutrition accumulation. If the light is not enough, the growth is slow, the branches grow too much, the growth is slow, and even cause the fruit to shrink and fall off. Passion fruit is a long-day plant, with photoperiod effect, that is, long sunshine (sunshine hours more than 12 hours) can promote flower bud formation and flowering. Generally speaking, after planting in early spring, water and fertilizer and other cultivation management work is done well, and it can continue to blossom and bear fruit in the summer of that year.

6. Temperature: the temperature requirement of passion fruit is basically the same as that of ordinary tomato, which has a wide adaptability and adapts to planting in the north and south (the north should winter in the greenhouse, and the south should be covered with cold protection before the frost period above 1400m above sea level in order to survive the winter safely. otherwise, the upper part of the main stem and side branches are mostly frozen and withered, or even the whole plant is frozen to death.

7. Pruning and pruning: after the passion fruit is planted, a pillar should be inserted at the seedling stage to lure the main vine on the scaffolding, and when the main vine is 1 meter high, cut off the terminal bud and let it grow out of the lateral vine, leaving 2 lateral vines on each side to grow on both sides. when the lateral vine grows to 2 meters, the top of the lateral vine will be cut off to promote the growth of secondary lateral vines. If the horizontal scaffolding cultivation, should wait for the main vine to reach the scaffolding, leaving the side of the vine to grow averagely in all directions. Passion fruit should not be cut heavily, and there is no need to cut it every year. If excessive pruning, it is easy to make the main vine gradually wither, and in serious cases, the whole plant will die. Generally, after each batch of fruit is harvested, 3-4 nodes of each side vine will be cut short to promote its re-growth of lateral vines. At the same time, the branches that grow too densely must be thinned every summer, or the branches that hang down and drag the ground will be cut off about 20-30 cm from the ground to maintain good ventilation.

8. Fertilization: the fertilization principle of passion fruit is that the ratio of nitrogen, phosphorus and potassium is 2-1-4.

9. Prevention and control of diseases and insect pests: passion fruit has strong stress resistance and less diseases and insect pests. When aphids, red spiders, leafhoppers, beetles, yellow ants and other pests and powdery mildew are found, they should be controlled in time.

Powdery mildew: you can use agricultural antibiotics, such as agricultural green streptotoxin, "carbendazim" and other 200~400ml liquid spray, once every 4 Murray every 5 days, a total of three times.

Red spider: the insect body is small, it is difficult to find with the naked eye, and the symptoms are leaf yellowing and fledgling. When this symptom appears, you should carefully check the back of the leaf. If it is a red spider with the size of a needle, it should be sprayed and prevented in time. "dimethoate", "omethoate" and "insecticidal phosphorus" can be used for spraying, and the front and back of the leaves should be sprayed evenly when spraying. Spray once every 5 days for three times.

Aphids: can be used to control aldicarb, dimethoate, dichlorvos and so on.

Note: the above pesticides are forbidden to be used 30 days before fruit picking, otherwise it will be harmful to human health after eating.

10. Artificial pollination: passion fruit blossoms around 11:00 every morning, artificial pollination is done in time after flowering, and pollination is completed before 4 pm. There are two methods of artificial pollination: (1) apply the pollen evenly to the three stigmas of the pistil with a brush; (2) collect the pollen sac with tweezers and put it into an average clean cup, then add water to make the pollen dissolve into the water, and then spray the pollen water on the pistil stigma with a sprayer. Artificial pollination can improve the seed setting rate.

11. Timely harvest: passion fruit falls to the ground naturally after ripening, and should be picked up in time. It is best not to pick up the fruit for more than three days, otherwise the fruit will rot quickly due to sun and rain.

The culture method of Xiaoli flower, how to raise Xiaoli flower

Xiaoli, also known as Xiaoli, passionflower and so on, is a dwarf variety of Dahlia. The flowers and colors are gorgeous, burning and shining, in a variety of states. With a long florescence, it is one of the most famous flowers in the world. The plant type is short, the flowers are colorful, and the full bloom coincides with the National Day, which is most suitable for family potted plants.

Culture methods of Xiaoli 1. Soil selection

Potted Xiaoli needs to choose a suitable medium, which can be made by mixing garden soil, cinder and fine sand, or adding some rotten leaf soil. Spread broken tiles at the bottom of the flowerpot as a drainage layer, put in the medium, you can add some base fertilizer appropriately.

2. Sufficient light

The growth of Xiaoli flower needs sufficient light, the daily light had better not be less than 6 hours, not excessive sunshade, so as to avoid poor growth. In spring, autumn and winter, Xiaoli can be exposed to direct light, but in hot summer, direct light can be avoided and can be maintained in bright places. In terms of temperature, Xiao Lihua likes a cooler environment and is more afraid of heat. When it is hot and sunny in summer, it should be properly shaded, or spray water to cool down. It is also not resistant to frost and cold. When the temperature drops below 10 ℃, it will go into dormancy. The suitable growth temperature of Xiaoli is between 15 ℃ and 28 ℃.

3. Temperature control

Xiaoli likes cold and afraid of heat, the temperature in northern China is more suitable, from the Summer Solstice autumn will blossom, and the Yangtze River basin, high summer temperature, in a semi-dormant state, must be foliage shade, spray cooling.

4. Large amount of water

Xiaoli has luxuriant branches and luxuriant leaves and a large amount of water consumption. if it is short of water to strengthen the light, the light will scorch the leaf edge, and the heavy leaf will be deciduous. If there is too much water, the root is easy to rot, so the pot soil should be neither dry nor wet, flowering period, summer watering should be more, spring and autumn should be less, rainy days should prevent stagnant water, put the flowerpot high, before the autumn harvest, less or no watering.

5. Water and fertilizer management

Xiaoli likes fertilizer. In addition to applying sufficient base fertilizer, 10% cake fertilizer and water are applied every 10 to 15 days during the growing period except in the middle of summer. After budding, 1% potassium dihydrogen phosphate is applied to promote the flower color. Xiao Lihua does not have high requirements for water and fertilizer, watering is generally more in summer, less in spring and autumn, keep the basin soil not dry and wet, avoid stagnant water in the basin, and pay attention to drainage in rainy seasons. When fertilizing, base fertilizer should be fully applied when planting. During the growing period, thin liquid fertilizer should be applied every 10 Mel 15 days, and some 1% Mel 3% potassium dihydrogen phosphate should be applied during flowering to promote flowering.

Points for attention in breeding Xiaoli 1. Pruning and pruning

In the breeding process of Xiaoli, in order to control the flower pattern and promote flowering, pruning can be carried out. In the period of growth, often pick the heart, can make Xiaoli more branched, branches dense. In the process of growth, some withered and diseased leaves can be cut off to promote the healthy growth of Xiaoli.

2. Pest control

The diseases and insect pests of Xiaoli flower are not common, but there will be powdery mildew, brown spot, virus disease and the harm of borer larvae, which need to be detected in time and controlled in advance.
