1. Timely fruit thinning and fruit setting:
Fruit thinning is carried out 15-20 days after flowering. First, the pollinated malformed fruit, disease fruit, stiff fruit, small fruit, etc. are removed, while the normal fruit with thick and well-developed fruit stalks is reserved; The number of fruits is generally 3 to 4 for long and strong fruit branches, 2 to 3 for moderate fruit branches, and 1 for short fruit branches. During the fruit-bearing period, generally delicious kiwifruit retains 23,000-25,000 per mu, and Chinese kiwifruit retains 24,000-28,000 per mu. In view of the unsatisfactory fruit setting in some orchards this year, everyone takes different measures according to the growth of the fruit trees and the results, and the poor pollination fruits should be eliminated in time.
2. Top dressing:
In early June, 200 kg of organic nutrient fertilizer was applied per mu during the fruitful period, or 1 kg of nitrogen, phosphorus and potassium compound fertilizer was applied to each plant, and 0.5 kg of microbial bacterial fertilizer was added.
3. Irrigation:
June is the critical period for kiwi fruit water demand, and water supply must be guaranteed to meet the growth of kiwi fruit. According to soil moisture, combined with fertilization, timely irrigation should be carried out, and integrated water and fertilizer fertilization should be implemented conditionally. Irrigation must be avoided at noon, otherwise the ground temperature will decrease rapidly, causing wilting of the tree.
4. Pest control:
After the fruit is fixed, the whole garden is used once to prevent and control pests such as stink bugs, wax cicadas, oriental small nails, and brown spot disease. The agent can be selected as 2.5% cyhalothrin 2500 times solution, plus agricultural resistance 120 or 800 times polymycin.
5. Biological control:
In mid-to-late June, the whole garden artificially releases predatory mites to prevent and control red spiders. Generally, each kiwi fruit can be hung in a bag and hung at the branch of the branch.
6. Scientific summer shears:
The low-temperature rainy weather on May 7 and 8 of this year is very unfavorable for kiwi pollination, resulting in poor fruit setting in some orchards and vigorous branch growth. Excessive dense branches and entangled branches should be removed to maintain the balance of vegetative and reproductive growth, and at the same time tie the vines evenly to improve the ventilation and lighting conditions. It is appropriate to distribute the flower spots and light spots on the ground under the shelf at about 12 noon.
7. Weed management:
When the grass or weeds in the orchard grow more than 30cm, stubble cutting shall be carried out. Generally, the stubble shall be left at 10cm, and the cut grass shall be covered on the tree plate to remove the malignant weeds in time to keep the orchard wet and cool and prevent high temperature burns.
