Key points of Orchard Management in September

The weather gradually entered the Autumn Equinox in September, when the climate turned cool, which is not only a bumper harvest season for fruit growers, but also the most important period of the year. A little carelessness may lead to a serious reduction in yield and quality. So how to manage the orchard in September? Let's take a look.

1. Shaping and pruning

In September, we carried out reasonable branch thinning for closed trees and closed canopy, and the objects of branch thinning were erect branches, sprouting branches and competitive branches on auxiliary branches, so as to increase the light in the crown and promote fruit coloring. In order to ease the tree potential, balance the growth and development of branches and buds, and increase the mining light of the inner chamber, the prosperous and long trees with small angle and closed inner chamber should open and pull branches in time. When the new shoots are close to growth or have become lignified, it is necessary to soften the 3-5 upright new shoots or upper dorsal branches of the main branches germinated at the lower part of the middle trunk.

2. Drainage and waterlogging prevention

The temperature turns cool in September, which is also the season of continuous autumn rain. Rain Water increases and the soil moisture is large, which can easily lead to the occurrence of diseases and insect pests and root rot. Therefore, it is necessary to do a good job of drainage and waterlogging prevention in time, maintain loose soil and good permeability, create a suitable environment for root growth and development, and improve fruit quality.

3. Remove the bag

The biggest advantage of fruit bagging is to improve the appearance quality and reduce pesticide residues. The improvement of appearance quality is highlighted in the surface smoothness and coloring, which is a commonly used technology in fruit tree planting. September is also a good time to remove bags, for double-layer inner red fruit bags, it is best to remove bags twice, the best time to remove bags is cloudy or cloudy days, sunny days should be at 9: 12 and 3: 7 p.m., in addition, bags can be removed 10-15 days before normal picking in high altitude areas.

4. spraying to prevent disease and replenish calcium fertilizer.

After removing the bag, the skin of the fruit is delicate, which is easy to be infected with red spot disease, stomata enlarged, resulting in cracks, calcium deficiency, calcium deficiency and other diseases, resulting in cracks on the fruit surface and reducing fruit storability and commercial performance. Therefore, after removing the bag, fungicides and calcium fertilizer should be sprayed 1-2 times in time, and it is necessary to spray organic potassium fertilizer to promote the fruit to be colored and colored in advance. Crack timely harvest is also very important, generally according to the fruit growth period, that is, the number of days from falling flowers to maturity to determine the picking time.
