Planting technology and management of kiwifruit

Site selection: it is suitable to plant in mountainous areas with convenient transportation, sufficient light, relying on water sources, moderate rainfall and slightly higher humidity. Garden construction: planning roads, irrigation and drainage systems, fertilizer management rooms, etc. Scaffolding: flat-roofed scaffolding is often used. Fertilization: applying base fertilizer before planting, applying a small amount of fertilizer for many times in young trees, and topdressing after sprouting and flourishing period. Management: timely planting, pruning, active prevention and control of diseases and insect pests.

I. selection of sites

Kiwifruit is suitable to be planted in mountainous areas with convenient transportation, sufficient light, relying on water sources, moderate rainfall and slightly higher humidity, and generally choose loose and permeable sandy soil, or hilly and mountainous areas with sandy soil and or loose soil rich in humus.

II. Establishment of a garden

After selecting a good site, first plan the road, drainage and irrigation system, fertilizer management room, etc., and then plan the planting land to ventilate the dark trench. Kiwifruit is suitable for planting in hills and mountains at an altitude of 400-1200 meters, and can be built in hills and mountains with slopes of 10-15 degrees. During this period, a greenhouse can be built, heavy pruning in winter, timely renewal of rejuvenation fertilizer, and re-application of base fertilizer and timely irrigation. In order to avoid kiwifruit cracking.

Third, build a greenhouse frame

Kiwifruit can generally use a flat-roofed greenhouse frame, can use the original small diameter tree as a living pile, plus a small number of replaceable bamboo piles, important parts can use concrete piles, on-site frame height is 1.8m, can be used 10-12 wire vertical and horizontal crossing is a "well" grid, wire spacing is about 60cm.

IV. Base fertilizer

According to the variety characteristics of kiwifruit, the expected yield and soil fertility determine the amount of fertilization. in the potholes before planting, each plant can apply 2.5 kg fruit wood fertilizer, and young trees can apply a small amount of fertilizer for many times, and then fertilize 3 times a year. Topdressing twice, that is, winter fertilizer, can be selected after fruit harvest, each plant can apply 20 kg organic fertilizer and 1.5 kg phosphate fertilizer.

5. Topdressing

Topdressing can be carried out for the first time after sprouting, and 2 kg of nitrogen, phosphorus and potassium compound fertilizer can be applied to each plant to supply nutrition for spring shoots and fruiting trees, and for the second time, topdressing fertilizer can be applied during the vigorous growth period, and an appropriate amount of fruit wood fertilizer or compound fertilizer can be applied. Because the root of kiwifruit is fleshy root, shallow trenches should be dug slightly away from the root, and then fertilizer should be applied and sealed to prevent root burning. Timely irrigation must be carried out after fertilization in the dry season.

VI. Late management of Actinidia deliciosa

1. Young trees planted in that year

First of all, three full buds are left at the base of the plant, and the others are cut short, and then the sturdy branches are retained as the trunk, which is generally carried out by light cutting, which is beneficial to the rapid expansion of the crown in the following year.

2. Trees that enter their infancy after growing for one year

When cutting in winter, try to distribute the fruit mother vine on the main vine evenly on the shelf, on the basis of promoting the growth of main vine, side vine and fruit mother vine, and then gradually expand the proportion of fruit vine.

3. Adult trees

The adult tree should be trimmed lightly, and then the fruiting vine should be cut short. 4-5 buds can be retained at the cut, while only long vines can retain 4-5 buds, which can promote the germination of 2-4 new shoots. For strong-growing vegetative vines, you can cut off the full-length 1-hop 3 or 1-top 2 vines to promote the transformation into fruiting mother vines, and for long medium-fruit vines and overlapping vines, 8-10 buds can be retained, and then the others can be cut short. The moderate fruit mother vine can retain 5-6 buds, while the weaker ones can retain 3-4 buds.

4. Old and weak plants

During this period, the fruiting vine with full growth at the base of the mother vine should be retained, which can be pruned to the strong part, and the weak mother vine can be cut off from the part where there are latent buds at the base to promote the latent bud sprouting to send out robust new shoots, usually 15 days after deciduous leaves in winter. Pruning 15 days before sap flow in early spring.
