Manage the mulberry field well in the coming year
I have been raising silkworm for more than 20 years, and my annual sericulture income is more than 20,000 yuan. To sum up, high quality and abundant mulberry leaves are the key. The good management of mulberry in winter is ample guarantee for Mulberry in the coming year. The specific approach is as follows: First, do a good job pruning mulberry, pruning work. In the winter, the branches, dead and dry branches of the trees are trimmed. The overwintering pest mainly lurks in the mulberry gap and sleeps over the winter. Through pruning, it can reduce the wintering base of diseases and insect pests and reduce the damage to mulberry trees in the following year. After the pruning, the trees are neat, airy and transparent, and the mulberry nutrient concentration will be concentrated next year, which will increase production. Note that the sawing and cutting must be near the bifurcation, and the incision should be smooth and smooth to facilitate healing; the dry pile from the saw must be transported out of the mulberry field and burned. The second is to do winter plowing work. This part is more effective. The mulberry field winter plowing can improve soil structure, maintain fertilizer and water, increase soil aeration, promote soil microbial activity, make the nutrients that are difficult to use in soil become available, and improve soil fertility. In addition, we can reduce the growth of weeds in mulberry fields by plowing, and expose the insects that are buried underground to the top and freeze to death. However, the winter plowing should choose the timing, generally after the mulberry defoliation, winter plowing requires a depth of 15 to 20 cm, clods do not break. The clods can be frozen and thawed by winter rain and snow, which can achieve the effect of killing insects, loosening, accumulating water, and increasing soil fertility. The third is to apply good winter fertilizer. Mulberry garden winter fertilizer mainly organic fertilizer. Such as pigs, cattle, sheep fat bar, silkworm sand, waste and other organic fertilizer, apply 2500 ~ 3000 kg per acre. Winter fertilizer has a great effect on the growth and development of mulberry trees in the second year. At the same time, it can also improve the soil and maintain the fertility of mulberry fields. The winter fertilizer should be properly deepened. It is generally controlled at about 25 centimeters to promote the deep development of the mulberry roots. In the case of insufficient fertilizer sources, it is possible to grow green manure crops such as milk vetch, humus, and so on in the mulberry field. When the green manure crops are budded, they are turned into the soil and 200 to 300 pounds of lime per acre is applied. This is a continuous 3 to 4 In the year, soil fertility can be greatly improved, and soil water retention and fertility enhancement. The fourth is to cut the tip moderately. Moderate mulberry cuttings can increase the germination rate, increase the growth height of shoots and shoots, reduce flower and fruit and pests, and increase the yield and quality of mulberry leaves. Cutting time is generally performed in December. The degree of cutting is determined according to factors such as the mulberry variety, branch length and tree type. General branches left 130 cm cut tip more appropriate. The shorter shoots cut off the top shoots. The cut-off strips must be transported out of Mulberry Park and burned in time. Fifth, do a good job of mulberry garden drainage. Due to the lack of sunshine in the winter and the continuous rainy weather, the mulberry garden flow is poor and it will affect the roots of mulberry trees. Therefore, for some mulberry parks with poor drainage, drainage work must be done. Experts commented on Gong Yongchang, chief of the station of Jiangyang District Agricultural Bureau. The management method of the sericulture winter tube is very important and is an indispensable part. To grasp the sericulture winter tube is the key to whether there are abundant and high-quality mulberry leaves in the coming year. Wang Yiwen’s silkworm rearing can yield high yields each year. He has a more accurate grasp of the mulberry winter tube method, including when to trim and cut, which period of fertilization, and the prevention and treatment of pests and diseases. In fact, as long as we understand the characteristics of mulberry winter, proper management methods, the next year there will be a guarantee of mulberry.
