When picking, the sugar content must be greater than 6.5%, and the fruit seeds are dark brown. If the fruit is mainly fresh, the sugar content is 7% is the best; if the fruit is mainly stored, the sugar content is 6.5%. Chinese kiwifruit should be picked from late August to early October, and delicious kiwifruit should be harvested from early October to mid-November.
If the fruit is bagged, the bag of the fruit should be peeled off 3 to 5 days before harvesting, and watering should not be carried out within 5 days before fruit picking to reduce the natural moisture in the fruit, prolong the storage time and ensure the storage effect. Gloves must be worn when picking to avoid scratching the appearance and affecting the merchandise. Note: Fruits are dewdrops or can't pick fruit in rainy days; avoid high temperature picking on sunny days (no picking from 11:00 to 15:00).
Protective blade
The fruit is about to mature, and it is the best period for photosynthesis to accumulate nutrients. It is necessary to pay attention to the protection of the leaves. The quick-acting fertilizer can be applied once 15 days before harvesting, and 0.3%~0.5% urea + 0.3% potassium dihydrogen phosphate is sprayed on the leaves. 1~2 times, to ensure that the leaves are intact, thick and dark green.
Water management
Kiwifruit roots belong to fleshy roots and are sensitive to soil moisture requirements. They are wet, afraid of dryness, and afraid of water. They are ditched according to the slope of the orchard and soil conditions. The orchard with thick soil layer and soil viscosity is deep. Generally, the depth of the trench is more than 50 cm and the width is 40 cm. The depth of the furrow is about 80 cm and the width is 50 cm. The shallow orchard can be appropriately lowered. In the event of heavy rain, the water surface should be below 20 cm below the ditch, and keep the compartment and the furrow connected to the external drainage ditch.
Post-harvest management
Fruit-harvesting: Applying fruit-harvesting fertilizers in time after harvesting, with 40%~45% content of quick-acting compound fertilizer, 40~80 kg per mu, to quickly restore the tree potential. Light pruning after fruit picking: combined with the application of fruit picking, slight trimming, removing dead branches, weak branches, pests and branches, and burning the cut branches to reduce the source of pests and diseases. Note: The trimming tool should be disinfected. Spraying after fruit picking: Pests and diseases are one of the main causes of early defoliation of kiwifruit. It is necessary to do a good job in disease prevention and pest control in orchards to ensure the integrity of the leaves and delay the defoliation time. Spraying Bordeaux mixture (preparation of Bordeaux mixture, copper sulfate: quicklime: water = 0.7:1:100), or using stone sulphur or other bactericidal and insecticides.
