High-quality cultivation method for kiwifruit
The choice of kiwifruit in the garden is widely adaptable and can be planted on plain or mountainous areas. When building a garden, choose a place where water is abundant, leewards are sunny and the soil is fluffy and fertile, rich in organic matter, in order to facilitate the growth of the root system.
The planting time can be planted after the late autumn leaves fall to the early next spring before sprouting, especially after the late autumn leaves are best planted, which is conducive to the recovery of the root system. The time for planting in early spring should not be later than the end of February.
Shelf type and density kiwifruit have a stronger growth potential, and they should adopt T-shaped racks or scaffolds for cultivation. The planting density should be 3-4 meters and 3-4 meters, which means 42-74 acres.
Pruning and Pruning Pruning is the key skill for the good harvest of kiwifruit. The rational tree shape of kiwifruit is a single backbone double main vine, while in the winter pruning, the combination of primary sparse shearing and short shearing is used. For the first-year result, the female vines are retracted and renewed, and the branches, branches and weak branches are eliminated. The remaining branches with a diameter of 1 cm or more are selected as the resulting vines, and according to the growing trend, the percentage is shortened by 20%-60. %, remove the weaker part.
Pollination and fruiting kiwifruit are dioecious, requiring cross-pollination to set fruit and develop normally. The proportion of male to female is 5-8:1. In order to obtain good quality and fruitful harvests, fruit thinning must be carried out. The fruit thinning time is appropriate in the early fruit setting period. The principle of fruit thinning is to remove the malformed fruit, disease and fruit, lateral flower, small fruit, main flower and fruit.
Fertilizer Management Kiwifruit is a fruit tree that requires higher fertilizer and water and requires a lot of fertilizer. To reuse basal fertilizer, basal fertilizer is mainly farmyard manure and bio-organic fertilizer, accounting for 70% of the annual fertilization amount. Supplementary strong fruit fertilizer, dominated by bio-organic fertilizer, accounting for 30% of the annual fertilization. After the fruit is harvested, the base fertilizer is applied deeply. The strong fruit fertilizer is applied after the fruit has been set.
When the kiwi fruit harvested from fruits was mature, there was no apparent change in the appearance color, and the content of soluble solids in fruits was mainly used as the index of harvest. Soluble solids content of more than 70% can be collected, reaching 8% -12% for the best harvest period. The bactericide is fully sprayed 3-4 days before fruit harvest to reduce the erosion of fruit during storage and remove the fruit stains.
