Strengthen the ground management of kiwi gardens in spring: clear the rotten diseased branches, powdery mildew diseased branches and grasshoppers in kiwi gardens before the beginning of March, remove the leaves, dead fruits, hanging branches and pull branches, and clean the ground The fallen leaves, fallen branches, diseased fruits, paper bags and packaging wastes were burned and buried in tree trays in a concentrated manner, striving to be comprehensive.
Scraping old warped skin: Combine the scraping of naturally generated old warped skin, thoroughly scrape old warped skin and disease spots caused by rot disease and branch ring disease, and strive to achieve "one scrape, two coats, three wipes" "Four, four wrap, five bridge" technical requirements, can be applied with methionine acetic acid, copper humate or bacteric acid paste. Wound protection agents must have three characteristics, that is, they have the effect of eradicating, being harmless and promoting healing.
Spraying the tree body: Spray the kiwi tree body in time in early March. The spraying should not only prevent diseases and insect pests, but also supplement the tree body. The specific plan is as follows: ①25% propiconazole EC 4000 times liquid + 40% chlorpyrifos 1000 times liquid + fruit Friends amino acid 200 ～ 300 times solution + Roushuitong 4000 times solution; ② 25% propiconazole 4000 times solution + 40% fetalphos 1000 times solution + Guoyou amino acids 200 ～ 300 times solution + Roushuitong 4000 times solution; ③General Dejin 400 times solution + 40% chlorpyrifos 1000 times solution + fruit friend amino acid 200-300 times solution. The spray on the tree should be even and thoughtful, shower-like, and the ground should also be sprayed.
Do well in the underground management of spring kiwi orchards and add organic fertilizer + biological bacterial fertilizer: At present, due to years of partial application of chemical fertilizers, kiwi orchards in Shaanxi Province do not pay attention to organic fertilizers and microbial fertilizers. There are three common deficiencies. The content is less than 1%, which can not meet the requirements of high-quality fruit production; the second is the lack of beneficial microorganisms. Due to the excessive application of chemical fertilizers and pesticides, the beneficial microorganisms in the soil are killed, resulting in soil compaction, more and more pathogenic bacteria, and fertilizer utilization Low, poor soil structure, and reduced fruit quality. Third, lack of trace elements, especially calcium, magnesium, zinc, boron and other element problems, bitter pit disease, yellow leaf disease, small leaf disease, fruit shrinkage and so on. Therefore, a sufficient amount of organic fertilizer should be applied per acre, and 1-2 tons of high-quality rotten cooked cattle and sheep dung + 200-400 kg of biological bacterial fertilizer should be applied per acre in the grown-up garden, and 10-20 kg of soil conditioner should be properly mixed. Mix organic fertilizer with topsoil, then ditch water to promote rooting and germination.
Tree tray treatment: Treat the soil around 1 meter around the trunk with chlorpyrifos 300-400 times liquid after startle and before Qingming, and control pests such as heartworm, chafer, cotton apple aphid.
Orchard grass: The pattern of orchard grass is divided into two modes: natural grass and artificial grass.
Natural grass: artificial control of woody stems, plants that are too tall, roots too deep, and highly competitive malignant weeds such as Chenopodium spp. Grass, fertilization to promote development, strengthen protection and development, through two or three years of development, gradually develop beneficial grass, control malignant grass, to achieve the purpose of orchard grass.
Artificial grass planting: It is generally implemented by the method of "planting grass between rows, clearing and mulching between plants", and grass species and leguminous plants are commonly used as grass species. Such as clover in the legumes, alfalfa and so on. Poaceae grass species such as rattan grass, bluegrass and so on. The most commonly used in production today are alfalfa and rattan grass.
