How many years can kiwifruit be planted?

Kiwifruit is named because its skin is covered with hair and looks like a macaque. It is a kind of fruit with fresh and tender quality, rich nutrition and delicious flavor. So, how many years can kiwifruit be planted?

First, how many years can kiwifruit be planted?

Kiwifruit is a large deciduous woody vine with dioecious plants. Under normal circumstances, it takes 5 years to plant to bear fruit, and if properly managed, it can be advanced to 4 years.

Second, the key points of kiwifruit cultivation.

1. Site selection

It is better to choose mountainous areas with convenient transportation, sufficient light, relying on water sources, moderate rainfall, slightly higher humidity, loose and well-ventilated sandy loam or sandy soil, or hilly and mountainous areas rich in humus. After the site is determined, first plan the road, drainage and irrigation system and fertilizer management room, and then plan the ventilation ditch of the planting land.

2. Fertilization

The amount of fertilizer application is determined according to kiwifruit varieties, planned yield and soil fertility. Before planting, fruit wood fertilizer 2.5kg could be applied to each tree in the pothole, and a small amount of multiple fertilizers were used for young trees. After that, it is generally fertilized 3 times a year, once and twice after topdressing. The base fertilizer, that is, winter fertilizer, was applied after fruit harvest, each plant was treated with organic fertilizer 20kg, and mixed with 1.5kg phosphate fertilizer.

The first topdressing was applied after sprouting, N, P and K compound fertilizer 2kg was applied to each plant to enrich spring shoots and fruit trees, and the second time before the peak growth period, fruit wood fertilizer or compound fertilizer could be applied. Because the root of kiwifruit is fleshy root, it is necessary to dig a shallow trench far away from the root to apply chemical fertilizer and seal the soil so as not to cause root burning. Irrigation must be carried out after fertilization in the dry season.

3. Shaping, pruning and fruit thinning

Before pruning, kiwifruit is divided into winter pruning, summer pruning and male plant pruning. Winter shearing was carried out during the period from defoliation to one month before sprouting in early spring. Leave more main vines and fruiting mother branches, and cut off overdense branches. Thin and weak branches, cross branches and disease and insect branches. Summer shearing is mainly carried out from mid-May to early July to remove sprouting, heart-picking, thinning and binding, timely erase the sprouts on the trunk and arrange the space for the branches. Male plant pruning is carried out after flowering in May-June. Each plant has 3-4 branches, each branch has 4-6 buds, and when the new shoot is 1 meter long, pick the heart.

Generally, the fruit will be thinned 1 month after flowering. Leave middle fruit, sparse edge fruit, up to 1 fruit for every 4-5 leaves. General branches leave 1-2 fruits per 20 cm, weak branches 20-25 cm leave 5-6 fruits. The plant produces 50kg, and 500600 fruits should be left.

4. Pest control

The diseases harmful to kiwifruit include anthracnose, root-knot nematode, blight, quenching, root rot, fruit soft rot and so on. Among them, anthracnose harms not only stems and leaves, but also fruits, which can be controlled by spraying 800-fold carbendazim 2-3 times during sprouting. For root-knot nematode disease, fertilizer and water management should be strengthened and 30% carbofuran poisonous soil should be used to control the disease.

Kiwifruit cuttings usually take 2-3 years to bear fruit, and the ratio of male to female can be artificially adjusted to avoid too many male plants and low yield.
