Most of the low-yielding mulberry fields are caused by many shortages, old ages, fewer number of cultivars, poor varieties, and pests and diseases. The transformation of low-yielding mulberry fields is an important measure to increase mulberry leaf production and stabilize sericulture production. Therefore, the transformation of low-yielding mulberry fields should be based on specific circumstances and adopt appropriate technical measures: First, encrypted replanting 1, layering strains 2, strong seedlings to fill the gap: a wide row of mulberry plants, can be planted between the lines or rows of healthy saplings. Second, set plant update For older mulberry trees with declining tree vigor, a new method of planting and replanting can be adopted. That is, a robust mulberry seedling is planted at a density of 1000 to 1200 plants per acre per acre between rows of mulberry trees. Newly planted mulberry cuts and cuts, strengthens the tube, and promotes vigorous growth. Third, rejuvenation grafting 1. Rejuvenate and rejuvenate: For mulberry trees with tall trees, short shoots, and declining growth potential, the twigs can be reduced by 1 or 2 layers before the sap flow in spring. Due to the latent buds at the branches, dry the branches as much as possible at the branches, pay attention to sparse buds to stay, and regenerate the branches. 2. Grafting and changing: Suitable for the transformation of real mulberry and bad mulberry varieties, especially the real mulberry, with many flowers and leaves, small leaf size and low leaf production. However, the roots are well developed and grow vigorously, and the excellent mulberry varieties can be grafted quickly. Chenglin, improve the yield of mulberry leaves. The low-dry mulberry is rooted, and the middle-high-growth mulberry is multiplexed. The juvenile mulberry adopts tubular buds or veneered buds. After grafting, we must strengthen management and develop a tree. As the root system of the mother tree is developed, the new mulberry after growing up is very strong. After the sprout grows to a certain height, the core can be picked according to the requirements of shearing, and the branching can be promoted. In the year, 2 or 3 branches are formed to shorten the tree growth. Years, and significantly increase the yield of mulberry leaves. IV. Spring cutting and cutting The mulberry tree which has been degraded due to poor management can be rejuvenated by spring cutting. Before the mulberry sprouts in the spring, according to the original form of cultivation, the existing branches are cut off from the base at 2 to 3 cm, and the poorly growing branches and leaves are dried up. The piles and dead punches are all cut off, and the buds are properly sparse and strong, leaving 2 to 3 buds per branch. The mulberry tree with good trunk, declining tree vigor, short shoots, and few springs can be cut off at the bifurcation to strengthen the management of fertilizer and water, and promote its re-germination and cultivation of sticks to achieve the purpose of rejuvenation. V. Strengthening fertilizer management: One of the important factors for low yield in mulberry fields is the severe lack of fertilizer. Therefore, fertilizer is the material basis for high yields in mulberry fields. Normally, pure nitrogen is used to convert the amount of leaf production. Each kilogram of pure nitrogen can increase 50 kg of mulberry leaves. Therefore, low-yield mulberry gardens need to increase the amount of fertilizer, and pay attention to N, P, K fertilizer application, with a ratio of 7:3:4, especially in the sandy beaches and yellow mud soil is more serious phosphorus deficiency, while applying N fertilizer should be Increase P fertilizer. Fertilizers in each season accounted for the proportion of fertilization in the whole year: spring fertilizer accounted for 30%, summer and autumn fertilizer accounted for 50-60%, and winter fertilizer accounted for 10-20% to meet the demand for mulberry growth and fertilizer.
