At present, silkworm production is in the stage of silkworm rearing for small silkworms to continue feeding and generate silk protein. Therefore, the spring silkworm rearing is a crucial period to determine the high yield of silkworm cocoon.
Invigorating Youth and Joint Family Education
The day before the indoor temperature was guaranteed, the silkworms were warmed to 24°C. After silkworms are planted in the room, they are used to make up. First lay a piece of anti-dry paper inside the silkworm cocoon, and then lay a white paper on top and spread the silkworm eggs on a white paper. Spread the egg area for each egg 30 centimeters and 35 centimeters, and cover the eggs with a pressure. The egg nets were then covered with silk cocoons and the silkworms were shaded and kept dark. The temperature was 24° C., and the wet-dry difference was 1° C. to 2° C., which was protected for 2 days. The temperature was increased to 25.5° C. in the evening before receiving the ants. At the same time, qualified farmers should actively organize small co-education of small coops, fully implement smoldering and heating, eliminate open flame heating, ensure silkworm room temperature wet standards and human silkworm security.
Select the mature old Mulberry leaves this year later, but the temperature rises quickly later, mulberry leaves grow quickly, may cause mulberry leaf maturity is not enough, so the quality of the mulberry leaves should choose to cook well old age is better. For mulberry gardens without Shichun fertilizer, spring fertilizer should be applied in time to increase the yield and quality of Mu mulberry.
To prevent the main thorough disinfection in recent years, the main reason for the occurrence of silkworm disease is the poor awareness of silkworm farmers, re-treatment light defense, before silkworm rearing, silkworm rearing, silkworm rearing did not do a thorough and complete disinfection. Especially this year, due to the low temperature in the early period, the overall feeding of the silkworm is delayed, and the silkworm may encounter high temperatures in the later period. Therefore, the majority of silkworm farmers should be raised to prevent the main consciousness, and comprehensive and thorough disinfection and disease prevention measures should be implemented in sericulture production. Throughout the entire process, the disinfection and disease prevention work was strengthened, and the losses caused by the silkworm disease were minimized.
Batches to improve the elimination of weak and small silkworms
When 70% to 80% of silkworms are sleeping, it is advisable to add the net and increase the time of adding netting to not more than 10 hours after sleep. Qingtou feeds in batches, satisfies food and sleeps, and resolutely eliminates weak and weak silkworms.
Large silkworm breeding ventilation and silkworm encounter sultry weather, if not take effective measures, will affect the normal growth and development of silkworm. Therefore, the large silkworm period should pay attention to ventilation and thin air, satiety food work, after the fifth instar the second day after the expansion of the silkworm seat area to 40 square meters each, and feed enough good mulberry; create comfortable environmental conditions, so that Nibbled mulberry, silkworm body health. Conditional aquaculture can be applied to silkworm cocooning and sericulture techniques to increase silkworm resistance, save labor, and increase house utilization.
The management of Suizhong should not ignore the selection of high-quality square grids to go up the mountain, and add a peeling hormone for silkworm silkworm before silkworms, so that it can be used on top of the mountain and the barracks quickly, and it can increase the scarring rate of trace poisoning silkworms; Control at 23°C～25°C, humidity 65%～75%, air flow 0.5～1m/second, when mature silkworms are positioning camping, most of them have already formed into thin skins, generally when the mountains are up, open doors and windows to ventilate and exhaust Pick up clear mountain silkworms, strengthen ventilation, reach the goal of quick camping, use less silk and increase the quality of tannins, achieve timely picking, eliminate the sale of picking hairs, and sell them at the time of picking. Picking and selling separately from the next hoe, do not artificially reduce the quality of silkworm cocoon, in order to increase the economic benefits of silkworm production.
