One is sowing propagation, and the other is pruning propagation. Passion fruit planted in spring can bloom in July of that year and be harvested in September. After the second year, it begins to bloom in April every year. 1 year can open 5-6 batches, each batch of flowers is 20 days apart. It takes 60-70 days from flowering to fruit ripening, and the fruit is harvested for more than 4 months.

cultivation techniques

Choose land to build a garden.

Choose the right plot to build the garden, and the eggs don't need much soil. It is suggested that the gentle slope, terrace or flat land with rich organic matter, good drainage, deep soil layer, pH value of 5.5 ~ 6.5, convenient transportation and protection should be selected. After site selection, it should be erected in time. Eggplant is a vine fruit tree, which should be erected in time, such as hedge frame, shed frame, T-frame or simple bamboo pole support. , you can choose large scaffolding for yard planting. Scaffolding materials can be wooden columns, iron wires, bamboo columns, cement columns, stone columns, etc. The general height of scaffolding is1.8 ~ 2.5m.. According to the row spacing of (2~3) m× (3 ~ 4) m plants, the hole size is 70cm× 70cm× 70cm, and it is appropriate to plant 750 ~ 1 0,050 plants /hm2. If the density after the wet season is 1.2× 1.5m, 65438 can be reserved according to the tree condition. Planting should generally be carried out on cloudy days or sunny days after rain. When planting, fill the soil in layers and compact it, and straighten the root system. Appropriate amount of decomposed organic fertilizer and sandy loam can be mixed evenly to make planting soil or covering soil. After planting, water the roots and cover them with film or straw.

Field planting

Planting time: depending on the height of seedlings, seedlings can be planted when the height is more than 25 cm, and plots with watering conditions can be planted as soon as possible. It is best to wait until the rainy season begins in 5 ~ 6 days. Because of the dry weather, the plants planted before the rainy season should be watered once every 10 ~ 15 days to keep the soil moist.

Planting density: Eggs are vine fruit trees with long branches, which are suitable for greenhouse planting, with row spacing of 2 meters and plant spacing of 2-3 meters, with about 200 plants per mu; The row spacing of single-row hedgerow cultivation is 1.7- 1.8m, and the plant spacing is 3.5-4m, about 0/00 plants per mu.

Tiantuan management

The seedling height of the seedling feeder is about 8 cm, and the dense and weak seedlings are removed occasionally, and the interval is 4-5 cm 1 seedling. After planting in the field, intertillage weeds four times a year, and apply fertilizer 1 time in autumn and spring, with manure and phosphorus and potassium fertilizer as the main fertilizers. The stems and vines are more than 30 centimeters long, and the vines are climbing. During the pregnancy to the result, if the weather is dry, water should be poured in time.

Water and fertilizer management

Eggs like humidity, but they are afraid of drought. When it accumulates water, it should be drained in time. Irrigation should be done frequently during drought, especially in the fruit-bearing period, which requires a lot of water and should be filled with enough water. Scientific fertilization. In the early stage of the new species, nitrogen fertilizer was mainly mixed with peanut bran water, and each plant was sprayed with 0.2% urea and 15% peanut bran water or 15 kg human excrement twice a month. Fertilization amount increases with the growth of seedlings, and foliar fertilizer is sprayed. In order to promote early growth and rapid growth, watering is started twice 7 days after planting, with an interval of 7 days, and each bag is watered with 60 kilograms; After entering the production period, phosphorus and potassium fertilizer should be applied to promote flower bud differentiation, and 0.5 kg compound fertilizer and 0. 1 kg potassium fertilizer should be applied to each plant. Winter fertilizer is applied after fruit picking, mainly farm manure, with 20 kg of farm manure and 0.5 kg of calcium magnesium phosphate fertilizer applied to each plant. The fruit expands rapidly within 15 days after flowering, so the management of fertilizer and water should be strengthened, especially the application of potassium fertilizer to promote the rapid expansion of the fruit. Every year, the two sides of the tree alternate.

Plastic trimming

Shelf: After the seedlings resume growth, wipe off the side buds in time to make the main vine thicker, when the main vine grows to 50- 1500px. Pillars should be set to guide the shelves.

Pruning of 1-2-year-old trees: compound pruning method (double-layer four-feature shaping method) is mainly adopted. When the main vine grows to 70-2000px, two lateral vines are picked and put on the shelves respectively as the first main vine; When the plant grows to 150-4000px, two lateral vines are set aside from each lateral vine as the main branches of the second layer, which are respectively pulled in opposite directions to form a double-layer four-branch shape. During this period, the lateral branches below 2000px and between 80 and 4000 px should sprout, and all sprouted branches should be thinned or erased.

Pruning of adult trees: In order to prevent the crown from being too dense, prune as soon as possible after picking the fruit, but avoid pruning again. After harvesting the last batch of fruits in winter, all the fruiting branches are pruned from the base, leaving 3- 150px.

Freeze in winter

In areas with low temperatures, attention should be paid to cold and antifreeze, which can be covered with straw mats, orange stalks and films. At the same time, the delicate autumn leaves are cut off, most branches are shortened to the crown, and the incision is covered with film to avoid freezing the whole plant.
