First, cut the tip before the mulberry dormancy to cut the young part of the shoots, can promote winter buds enrichment, increase the germination rate in the coming year, thereby increasing the yield of mulberry leaves, while cutting tip can also avoid freezing dry tips, enhance the cold resistance of mulberry Reduce pests and diseases. Cutting time is controlled before and after the frost, combined with rearing silkworms in late autumn. If it has passed the appropriate cutting period, it needs to be cut when the sap has not yet flowed between the second and the third half of the early spring. The principle of cutting branches is to cut the length of the branches, and the length of the branches is cut. The length of the cut is about 1.5 meters. ~ 1/4, the length of 1 meter below the cut section of the green tip. Second, pruning Mulberry pests and bacteria in the dead boxing, dead branches, dry piles wintering, if not refurbished, will weaken the tree vigor, diseases and insect pests increase, therefore, pruning is important to increase the mulberry leaf production. Pruning is usually carried out after deciduous mulberry leaves in winter and before germination the next early morning. It is required to completely cut away dead branches, dry piles, and pests and branches, pruning should be smooth, and thrift should be removed without damaging the tree. It is advisable to trim the location close to the branch branches, and the sawn and cut branches must be transported out of Mulberry in time. Burned to prevent the spread of pests and diseases. Third, the end of the reconciliation bundle is to tie up the mulberry branches with straw to facilitate management operations in winter mulberry fields, but also to trap and kill pests to avoid wind and snow hazards. The end is usually done before winter ploughing after deciduous mulberry trees in late autumn. Before the spring of warmth from February to March of the following year, the solution of the sows removed must be burned to eliminate the overwintering pests hidden in the grass. Fourth, winter plowing and fertilizing Winter plowing can improve soil structure, improve physical and chemical properties, but also promote root growth, reduce pests and weeds. Winter ploughing usually occurs before leaves fall into the dormant state. At this time, the mulberry tree has entered dormancy, and it is necessary to plow 15-20 centimeters deep. The sandy soil near the roots should be lighter. It is best to combine winter plowing with winter fertilizer. Apply the organic fertilizer first to winter plowing. To save labor and improve efficiency. China Agricultural Network Editor
