One orchard covered grass
The orchard ground covered with wheat straw, rice straw, and mountain grasses can greatly increase the soil organic matter content, improve the soil structure of the garden, and improve the drought resistance of fruit trees; the orchard grass cover is carried out from September to October each year, and the thickness is the most suitable for 10-15 cm. Cover the soil with 3-4 cm of grass to prevent the grass from being blown away by wind and fire.
Second, the deep orchard
Deep fall in autumn will help maintain water and nutrients, increase soil permeability, and enhance the ability of roots to absorb water and nutrients. Generally, it is appropriate to deepen the soil from the outer edge of the colonization and the depth is slightly deeper than that of the main root system in the fruit tree (60 -80 Magic meters); fill the topsoil into the bottom when deep-turning, combine with autumn basal fertilizer, increase organic fertilizer, ripen the soil, and timely watering.
Third, prevent autumn
For the autumn fruit plot, it is necessary to quickly clear the channels and drain the accumulated water as soon as possible. The upper surface of the neck of the fruit tree should be opened to accelerate the aeration of the soil and prompt the root system to return to normal life as soon as possible.
Fourth, pull fruit trees
Autumn pull branches have the characteristics of easy pull, fast setting, good effect of slowing down, and high rate of flower formation. The non-backbone branch opening angles are the main factors, and branch opening angles can be about 85 degrees, which can effectively alleviate the early results of tree vigor; The opening angle of the branch with a small opening angle can be controlled at 40-50 degrees, and the tree with a large tree age can increase the opening angle appropriately.
Fifth, take heart autumn scissors
In October, for all uncapped shoots, all of the delicate parts that have not been lignified were removed, so that the nutrients flowing into the growing points accumulated in the wooded tissues, which promoted leaf hypertrophy and photosynthetic efficiency, resulting in shoot organization. Full, buds full; fruit trees carried out in autumn pruning, can reduce the local tree consumption of nutrients, promote the tree's overall nutrition accumulation, improve the tree's ventilation and light conditions, improve the quality of the results; pruning principle is to increase the pruning intensity, dare to bring fruit Pruning; especially in the winter when cutting all kinds of long branches need to be cut off, too crowded crowded branches together to remove, conducive to retain nutrients, promote flower buds mature, reduce winter pruning and nutrient consumption, improve the tree nutrient reserve.
