1.Summer cut skills

Mainly for the strong and prosperous branches, take the branches to open the angle of the branches and slow down the growth vigor; thin out the part of the shading vigorous branches; for the fruit trees that have too many fruit and the fruiting parts have moved out, hang the branches and top branches to prevent Breaking the branches and avoiding the results from stacking together is conducive to the growth and coloring of the fruit; pinching the vigor is to promote the branching of short branches and the formation of flower buds.


2.Pest control

At this time, you should pay attention to red spiders, apple aphid, apple leaf roller moth, leaf miner, peach heartworm.


3.Topdressing points

Topdressing fruit swelling fertilizer in mid-to-late July is beneficial to promote new roots, improve leaf function, increase single fruit weight, increase grade fruit rate and yield, enrich flower buds and tree body nutrition accumulation, improve tree body resistance, and provide high yield and high quality for the year Lay a good foundation for a bumper harvest in the coming year. Application of quick-acting compound fertilizer (high-nitrogen and high-potassium compound fertilizer) of about 50 kg per mu is beneficial to promote fruit swelling. Topdressing phosphorus and potassium fertilizer can increase fruit hardness and sugar content, and promote fruit coloring.

   

4.Weeding matters

In July, weeds grow vigorously, competing with fruit trees for fertilizer and water, affecting the ventilation and light transmission of fruit trees, breeding diseases and insects, and weeding should be ploughed and weeded in time. You can mow the lush green grass inside and outside the garden, by the side of the ditch, by the side of the garden, and by the side of the road, and press it under the tree tray.

   

5.Drainage management

July is the rainy season, with frequent rainfall, and flood prevention and drainage, soil and water conservation, and wind protection must be done well. In the rainy season, the soil moisture is too much and poor ventilation will inhibit the growth and absorption of the root system. The flat orchard can be managed by "riding cultivation", that is, take a 10 cm gauge * from between the rows and press it into the rows, so that the ground between the rows and the rows is 20%. The height difference of about centimeters increases the lower cortex of the canopy, which can not only store water, but also drain and prevent waterlogging, promote nutrient absorption, and avoid the accumulation of water to induce root diseases.
