(a) The third instalment had no food or medicine. It is required that the third-infant foraging must be added to the food, requiring that the co-requisitioners add food to the food, which is convenient for operation and can easily achieve the goal of 100% food. (b) Sleeping prematurely. After the technical request is over, there is a small amount of silkworms that are gradually meticulously cut, and most of the silkworms are eaten and fed to sleep, and 95% of them go to sleep and sprinkle lime to cover the silkworm sand and leftover leaves. Silkworms, isolated and reared in large quantities, and buried in small amounts. A small number of farmers in the production did not feed the leaves when they saw silkworms, causing large numbers of silkworms to starve or not sleep. (3) Incorrect shillings. When only mulberry is needed, the quicklime is required to cover the silkworm sand and leftover leaves, so as to avoid wet mold induced by silkworms or to affect the health of the leftover leaves from silkworms. Too little is produced in production, and care should be taken later. (d) silkworm seat too dense. Silkworms are so dense that they can easily catch each other and infect the disease. It is advisable to use a silkworm gap. (e) Eating too soon. The technical requirements require food to be eaten lately. Ninety-five percent of the silkworms feed the leaves only after the silkworms are produced. The production farmer starts to feed the leaves when he sees the silkworms. First, it is easy to damage the silkworm mouthparts to affect health, and secondly, the silkworms are easy to eat. Leftover leaves affect health, and the third is inevitable inequality of silkworm. The correct approach is to see the majority of silkworms, according to the standard mining leaf cleaning, cutting into the drug after the cut, the third instar sleep see 99% from the silkworm, 4 instar see 85% from silkworm silkworm disease prevention number one disinfection After 10 minutes, press 80% full to request Sang. Silkworm reared or eliminated in the evening. (six) sericulture mixed. In production, mulberry leaves are generally placed in a large silkworm room and are easily cross-infected. (7) The daily disinfection is not standardized. One was that twice-daily disinfection did not do it, and the other was that the lime used was not quicklime or fresh lime. (h) Do not remove sand in time. Without removing sand, silkworms can easily infest various diseases and injure them. Sand must be removed as required. (9) Do not pay attention to supplementary food. After giving Mulberry for 30 minutes, it is necessary to pay attention to observing silkworms. There is no need to make up for mulberry leaves. Grasp the standard of half an hour and observe the mulberry in time to ensure that the silkworms are full. (10) Poor management of mulberry gardens and poor quality of leaves. Mulberry leaves are generally too old. (11) The leaves do not meet the standards. (twelve) suspected leaf test feeding. No trial feeding was done on potentially contaminated leaves. (Thirteen) Most do not have a stepping pool, disinfectant only use lime. (14) Technical services still have loopholes. The above problems have the problems of the farmers themselves, and there are also problems with the service of technical instructors. In the future, the majority of sericultural technical instructors should strengthen the guidance of several key links such as daily disinfection, suffocating and feeding, expanding seats, and adding food to medicines.
