(1), single row, single plant, scaffolding planting, row spacing 5x4m.

(2) Single-row and double-plant greenhouse planting with row spacing of 2x8m.

(3) Single-row fence planting with row spacing of 2x6m.

You can choose one of the above planting methods and specifications.

Second, digging holes and applying base fertilizer.

Two months before planting, dig a planting hole with a depth of 0.6 m and a width of 1.2m according to a certain plant spacing, and return to the hole to apply base fertilizer one month before planting. Apply 20 kg of farm manure, 0.5 kg of calcium magnesium phosphate fertilizer and peanut bran 1 kg to each hole. The base fertilizer must be fully mixed with the topsoil and return to the depth of two-thirds of the hole.

Third, timely erection.

The trellis of passion fruit is dominated by crown and single-row fence.

Fourth, pruning

After the seedlings survive, leave 1-2 main vines on the shelf, cut off too many side branches, and vines will grow all over the shed in a short time. * The branches near the main vine bear fruit first. When the fruit matures and falls, cut off 2-3 knots in time. Each bud sprouting from the base can form a new fruiting mother branch. After harvesting the last batch of fruits in winter, cut all the fruiting branches from the base.

The first-grade vines of passion fruit are the main vegetative branches, and the second-and third-grade vines are the main fruiting branches, so cultivating strong second-and third-grade vines is an important link to improve yield.

Avoid pruning passionfruit in large quantities. Excessive pruning will reduce the yield, the main branches will wither, and the whole plant will die in serious cases.

Verb (abbreviation for verb) Fertilize reasonably.

In the early stage of passion fruit, nitrogen fertilizer was mainly applied and mixed peanut bran water was applied. Each plant is sprayed with 0.2% urea and 65,438+05% peanut bran water or 65,438+05 kg human excrement twice a month. Fertilization amount increases with the growth of seedlings, and foliar fertilizer is sprayed. 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. Every year, the two sides of the tree alternate.

Six, artificial pollination

Passion fruit blooms around 1 1 every morning, and artificial pollination is carried out in time after flowering, and pollination is completed before 4 pm. There are two methods of artificial pollination: (1), the pollen is evenly spread on the three stigmas of pistil with a brush; (2) Collect the pollen sac with tweezers, put it into a clean cup, then add water to dissolve the pollen in the water, and then spray the pollen water on the pistil stigma with a sprayer. Artificial pollination can improve the seed setting rate.

Seven, timely harvesting

Passion fruit naturally falls to the ground after ripening, so it should be picked in time. It is best not to pick the fallen fruit for more than three days, otherwise the fruit will be exposed to the sun and rain and rot quickly.
