Planting techniques of wild kiwifruit

Wild kiwifruit is known as the "king of fruit", generally growing in the mountains, pure wild environment, no pesticides, no fertilizer, no expansion agent. So, do you know the planting technology of wild kiwifruit?

1. Planting techniques of wild kiwifruit

1. Parcel selection

Kiwifruit like warm, moist, cultivation should choose leeward to the sun, the soil is deep, close to the water source, the slope is generally not more than 30 degrees, it is best not to plant in valley depressions, narrow basins, hilltops or tuyere. The garden should be built on the slopes with convenient transportation, loose soil, good drainage, high humus content, slightly acidic or neutral semi-sunny slope and semi-shady slope.

2. Sowing and raising seedlings

Seed collection and treatment: the fully ripe fruit was collected from September to October. After harvest, it was stacked and matured, softened or mashed, then scrubbed, rinsed with water to rinse out the pulp and peel, dried to remove miscellaneous seeds, placed in a ventilated place and dried in the shade, put into a fine gauze pocket and hung in a cold room for storage. Three months before sowing, the seeds were treated with sand storage, soaked in 40 ℃ warm water, soaked in 24 hours when the water dropped to room temperature, mixed with fine river sand of 10 times the seed volume, and was often turned to accelerate germination in the environment of about 5 ℃ for 40 to 50 days, and the seeds could be sowed when the seeds had a gap of 1 to 3.

Sowing and field management: it is appropriate to sow seeds at a depth of 5 centimeters in spring when sowing at 10 ℃. Because kiwifruit seeds are very small, they should be sown with fine sand, 1.5 grams per square meter, and covered with a layer of fine sand or humus after sowing, so that the seeds can not be seen. The thickness of the soil cover is 0.3 cm to 0.5 cm. Cover the bed with straw, shade the sun, and water it with a sprayer. Keep the bed moist and use a sunscreen to shade the sun on the seedbed after emergence.

3. Cuttage seedling

Softwood cuttings are generally carried out in early June, select the new shoots that grow well in that year, cut off the parts with sufficient tissue as cuttings, each section is about 15 cm long, retain 2 or 3 buds, and remove the leaves of the lower part of the cuttings. generally carried out in the greenhouse, plastic film-covered seedbed or in the field, cut in the substrate for fine sand seedbed, cutting depth of 5 cm 6 cm. To keep the cuttings moist in the field, shading treatment should be carried out immediately after cutting, and it can survive and take root after 1 month.

4. Planting and tending management

It can be planted in spring and autumn. Because kiwifruit is mostly dioecious, pollination trees should be arranged when planting. The best ratio of female to male is 8 ∶ 1. Before planting, the depth of soil preparation is generally 25cm 30cm, the planting pit is 30cm wide and 35cm deep, and the spacing between plant and row is 2.5m × 1.5m. Put the seedlings into the planting pit, fully stretch the root system, and then cover the soil gently and firmly after filling the ripe soil for two times. In the same year, when the young trees sprouted and the new shoots began to grow, the first topdressing was carried out, and the available nitrogen fertilizer urea was applied. The second topdressing is in late July, topdressing phosphorus and potash fertilizer can also be applied with human feces and urine to promote the full maturity of branches and full bud eyes, which is conducive to fruit development. Kiwifruit like temperature and wet conditions, generally can be combined with fertilization for irrigation, anti-freezing water before winter, spring irrigation after thawing, can meet the needs of its growth and fruit.

5. Shaping, pruning and fruit thinning

Shaping and pruning can be carried out in summer and late autumn, kiwifruit branches and buds grow vigorously, shaping and pruning are very important to increase yield and prolong fruit life. The scaffolding was mainly used to cultivate 3 main vines planted for 1 ~ 2 years and the main fruiting branches in the 3rd year. The fruiting mother branches and their fruiting branches were evenly distributed on the lateral vines by pruning, and the branches could be covered with branches after 3-4 years of cultivation. Irrigation and fertilization can be carried out in spring and autumn.
