Some of the pests in Qingyuan Park are overwintering in mulberry deciduous and mulberry field weeds. They should be cleared as soon as possible and burned in a concentrated manner to reduce the damage of pests in mulberry fields in the coming spring.
The upper part of the cut mulberry winter bar is not substantial and should be cut off to promote nutrient concentration, enhance the germination potential in the spring of next year, and increase the germination rate. The general bottom stays about 1.3 meters, and the short stays 1 meter.
Pruning and trimming will cut thin and thin branches and bars so that the nutrients will be more concentrated, which will help increase production. The old mulberry trees in the middle age, Mulberry boxing, dry branches, and dead punches are more important. They are important wintering places for mulberry pests. They must be pruned early in the winter and burned together.
In the winter ploughed mulberry field, the soil is more compacted due to weeding, leaf collection, and other agricultural operations. It should be plowed in winter to loosen the soil and promote the growth of mulberry roots. Winter plowing does not need to break up the clods in order to facilitate freezing and improve the soil.
Winter Mulberry strengthens management
In the winter, the growth of mulberry trees has stopped. To ensure the high quality and high yield of mulberry leaves in the coming year, we must make full use of the current slack season and effectively manage the winter mulberry fields.
