Timely drainage and cooling
It is rainy in summer, which is conducive to weed breeding and pests. It is necessary to timely cultivate and weed, improve the ecological environment of the orchard, reduce soil moisture, reduce the environment for pests and diseases, improve soil permeability, and improve the ability of trees to resist pests and diseases. Yao Chunchao pointed out that kiwifruit garden weeding and wetting and dehumidification are very important. In July, it is more rainy and cloudy, and it is easy to cause water accumulation in the rainy season. The dark and humid kiwifruit garden adopts dredging three ditch to ensure smooth water flow and no water in the rain. To avoid the root cause of hypoxia death and root rot caused by waterlogging. If you encounter the danger of water accumulation, take immediate measures to drain and dry out the root neck and part of the root system, and use the anti-root rot drugs to irrigate the roots.
Scientific and rational fertilization
The current period is the best period for the formation of kiwi fruit, which is also the period of upgrading, fat fruit and fruit solidification. It is necessary to apply nitrogen, phosphorus and potassium compound fertilizers, and appropriately increase the ratio of phosphorus and potassium fertilizer. At the same time, the leaf surface can be sprayed with organic matter. a mixture of fertilizer, calcium fertilizer, etc. Yao Chunchao reminded that it can be combined with drought-resistant watering, combined with the application of decomposed farmyard manure, and appropriately diluted with potassium sulfate compound fertilizer or high potassium fertilizer for fertilization.
Yao Chunchao stressed that after the results of kiwifruit, summer pruning will continue to adopt a combination of sparse and short-term combination, that is, to remove some of the branches that are overgrown in the dense place, and then appropriately wrap the branches around each other, which can increase the light in the canopy, while avoiding Leaves are susceptible to early defoliation.
Pay attention to pest control
In addition to devastating ulcers, kiwifruit has the greatest impact on yield and quality in summer leaf diseases. Yao Chunchao said that once the disease occurs, the cost of control is high, and it is easy to cause early defoliation, which seriously endangers the weight gain and quality of the fruit. In addition, it also needs to control brown spot, small salary, red spider and other pests and diseases. According to the actual situation of the orchard, the insecticide and fungicide can be selected in a targeted manner, so that the medicinal and foliar fertilizers can be reasonably matched, and the concentration can not be increased arbitrarily, or more types of fertilizers can be sprayed at one time to avoid phytotoxicity. In the summer, the spraying time should be carried out before 11:00 am or after 5:00 pm to avoid medication during the high temperature period.
