Kiwifruit planting field management techniques Kiwifruit coverage and red spider prevention measures
Kiwifruit planting field management techniques Kiwifruit coverage and red spider prevention measures. The northern kiwifruit producing area is a hot season from June to August. If the ground is not covered, the surface water will evaporate quickly due to high temperature, and the branches will stop growing, especially on the sides of the river. The ground is more serious. Therefore, it is necessary to cover the ground in time, reduce the surface temperature and increase the air humidity. The covering material may be selected from corn stalk, sorghum stalk, clover, weed, wheat straw, sawdust and the like. Coverage begins in June and ends at the end of August. The coverage area is 1 meter away from the tree tray, which is the main distribution area of ​​the root system. The temperature in summer is mainly high temperature and high humidity. In this environment, root rot, root knot nematode, leaf mold, fruit mildew and black spot, yellow disease and other diseases are prone to occur in kiwifruit fields. Pests, chafers, citrus ash, leafhoppers and other pests should be based on the principle of "prevention based, comprehensive prevention and control", and actively carry out the prevention and control of summer kiwifruit pests and diseases. The first is agricultural control. Strengthen cultivation management and enhance the tree. Guide summer trimming, improve the ventilation and light conditions of the orchard, and reduce the occurrence of scale insects. After the rain, pay attention to clearing the ditch to prevent water accumulation, reduce the humidity of the orchard and remove the weeds in the garden in time. The second is reasonable chemical control. Orchard in which bacterial flower rot occurs, sprayed with neomycin, and agricultural anti-120. Observed the young trees, and found that the chafers and citrus ash, such as adult worms, and other insects, timely sprayed with low-toxic pesticides such as buprofezin (chlorpyrifos) and chlorpyrifos. The beetle has a lighter orchard, which is brushed with a brush and sprayed on the orchard. The third is comprehensive prevention and control. Through publicity, strengthen the awareness of fruit farmers to improve soil, deepen the soil, increase the application of organic farmyard manure, biological fertilizer, prevent partial application of nitrogen fertilizer, chemical fertilizer, improve soil physical and chemical properties, adjust soil pH, and increase soil effective iron absorption. The prevention and control of red spiders in the kiwifruit garden has good control effects in 15% and August with 15% 哒螨 1500-2000 times liquid or broom. However, long-term use will produce drug resistance, with 1.8% avermectin 3000 times solution + soft water pass 4000 times solution or chlorpyrifos 3000 ~ 4000 + soft water through 4000 times solution. Each time the medicine is added, the water is adjusted to be neutral, and then the medicine is added in proportion, which can improve the medicine effect and save the medicine dosage. In the winter, clearing the garden to eliminate the wintering eggs can play a multiplier role.
