Detailed Explanation of Key Points for Kiwifruit Cultivation and Management Techniques After Autumn
After the autumn fruit harvest, applying base fertilizer in combination with inter-row tillage and weeding is very important. The fertilizer amount accounts for 60%-70% of the annual fertilizer application. Applying base fertilizer early can help restore tree vigor as quickly as possible, benefit the trees through winter, and ensure fruiting the following year. The base fertilizer commonly used is decomposed farmyard manure. Generally, 1500-2000 kg of farmyard manure is applied per mu, and 3000-500... for mature orchards.

The base fertilizer commonly used is decomposed farmyard manure. Generally, 1500-2000 kg of farmyard manure is applied per mu, and 3000-5000 kg for mature orchards, with a small amount of urea or compound fertilizer appropriately added. To prevent root-knot nematodes, scarab larvae, root rot, and other diseases and pests from damaging the tree roots, when fertilizing, 2% abamectin emulsifiable concentrate at 1000 times dilution and 50% thiophanate wettable powder at 1000 times dilution can be applied at the same time, mixed and sprayed into the farmyard manure. Fertilization method: adopt trench-style fertilization along the center of the tree row, 50-100 m from the main trunk, dig a long trench 20-30 cm wide and about 20 cm deep, apply the farmyard manure mixed with pesticide into the trench, mix chemical fertilizer with manure water, then pour it into the trench, and cover with soil after pouring the manure water. After the autumn fruit harvest, deep plowing to improve the soil can be carried out in combination with fertilization. In the first year, dig a ring-shaped trench outward from the outer edge of the planting hole, with a width of 30 cm-40 cm and a depth of 40 cm. In the second year, continue expanding the deep plowing outward from the edge of the previous year's deep plowing, and deep plow the entire orchard once.
