Earlier this month, the early autumn silkworm rearing began. It was a period of high temperatures, and this year it was a long-term high temperature. Therefore, it is necessary to do a good job of cooling work, such as outdoor curtains to shade, reduce the position of silkworms, and increase the number of times to Sang, each time to a relative reduction in mulberry. In the case of large silkworms, silkworms are promoted, and wet leaves are eaten during the day, and they are appropriately thinned. Each silkworm stock in the large silkworm stage is no less than 40 square meters; due to the influence of high temperature on the silkworm, the resistance is weakened, so it is necessary to strengthen the prevention. Disease disinfection, small silkworm disease prevention period number one, silkworm period to reuse fresh lime powder, once a day. In the early fall period, other crops use more pesticides and are likely to pollute the mulberry leaves. Therefore, to prevent pesticide poisoning, mulberry leaves must be eaten after the trial, and the use of dimehypo and pyrethroid pesticides should be prohibited in silkworm areas. The early autumn silkworms are finished in time for comprehensive cleaning and disinfection work, and are ready to feed the mid-autumn silkworms. Generally mid-autumn silkworms are reared from the middle and late August. The work of mulberry gardens mainly focuses on the management of water, fertilizer, and insects. This year due to the long-term high temperature and drought, we should promptly do a good job of drought relief. Where conditions permit, timely irrigation, irrigation should be in the morning and evening irrigation, once every 7-10 days. The mulberry field that cannot be filled with water should be poured and covered with rice straw and wheat straw. , weeds, etc., to reduce evaporation, inhibit weed growth, improve soil and other effects. The mulberry garden in the autumn fertilizer should be completed before the end of August, fertilizer can not be too much, generally 10 kg of urea per acre, if insufficient summer fertilizer, after the drought in early August after the application of urea 20 kg of urea, furrow or Shi Shi, Shi After the cover soil. There are many insect pests in autumn, and there are many pest species, such as wild silkworm, mulberry, mulberry, mulberry, red spider, mulberry mealworm, mulberry horse, etc. According to the pest information of various places, the right medicine should be used, "Mulberry-specific pesticides" should be used, and the residual period of pesticides should be well mastered so as to avoid poisoning in the silkworms.
