Summer silkworm yield measures
In summer and autumn, the weather changed greatly and there were more unfavorable factors encountered. In order to seize the high yield in summer and autumn, the following four measures should be focused on: First, strict disinfection and disease prevention Silkworms have a short interval, fresh pathogens, and a large amount of susceptible to infection. They must thoroughly sterilize the environmental sanitation of silkworm and silkworms. Take the first spray disinfection, and then clean and wash clean method, spray dose should be enough, face to spray. Strictly implement the "three-pumping guidelines" for "complete elimination in silkworms, continue elimination in silkworms, and eliminate them immediately after silkworms", and apply disinfection and disease prevention throughout the entire cultivation of silkworms. In the summer and autumn, when silkworms use pesticides, information should be exchanged with the leaf collecting households. The mulberry leaf to be used in the pesticide area must be tested and tested after the residual period to prove that it is not poisoned before it is collected. Summer and autumn silkworm breeding should be fly-proof, rodent-proof and avoid loss. Second, adjust the silkworm room temperature According to different climate characteristics in summer and autumn, take appropriate measures to adjust and improve the sericulture environment. The silkworm period is covered with a plastic film, which can maintain moisture and keep it healthy. During the silkworm era, large, spacious and well-ventilated housing should be selected to prevent stifling heat. Planting trees and shelters should be used around silkworm housing to reduce radiation. High temperature and sultry, it is necessary to strengthen ventilation, high temperature and dry when cooling and moisturizing. Third, strengthen the management of mulberry leaves Strengthen the mulberry fertilization and insecticide, promote the growth of mulberry, is the guarantee of summer and autumn silkworm harvest. Small silkworm stage (1-3 ages), suitable for ripening leaves with a green color and soft touch as the standard. In particular, mulberry mulberry mulberry purses accept mulberry should choose suitable mature and tender mulberry leaves. Avoid mulberry leaves contaminated by insufficient sunshine, old leaves, withering leaves, pests and leaves, and pesticides. The summer and autumn silkworm should be picked before the morning dew does not dry or in the evening. It is absolutely impossible to collect the leaves in the middle of the day (except for rainy days). The mulberry leaves that are harvested should be quickly harvested to prevent the mulberry leaves from disintegrating and withering. Fourth, strengthen feeding management First, when the silkworm species is transported, it is necessary to pay attention to the type of silkworm that cannot accumulate and accumulate, and try to avoid contact with high temperatures. The lead transport species should be carried out in the morning and at night, and should be spread out in a timely manner to prevent accumulation of heat and burn. When silkworm eggs are distributed, they should be carried out as soon as possible. Silkworm species can not be exposed to pesticides and all harmful gases to prevent silkworm poisoning. Second, the small silkworm rearing period adopts plastic film coverage, and the growth and development of silkworms are fast. It is necessary to enlarge the area of ​​silkworms in advance to prevent congestion and hungry. Chlorine silkworms were sterilized daily with chlorine-free 2% stabilized powder or fresh lime powder. When sleeping, use a silkworm disease, a sterilized spirit, and a 500-fold solution of chlorella to add food. Small silkworm leaves are immersed with soluble chlorine or 0.3% of silkworms, or sterilized, dehydrated, dried, and fed to silkworms. The third is the silkworm period to achieve three thin: the silkworm frame in the silkworm house is thinly received, the silkworm foil on the silkworm frame is thinned, and the silkworm head in the silkworm foil is loosened, which is favorable for ventilation and lowering the air. Temperature, and can fully eat. The silkworm period is especially high-temperature and humid, and it is necessary to eliminate silkworms and sand, and keep the silkworms clean and dry. During the silkworm era, labor-saving silkworm rearing should be implemented. The silkworm eradication silkworm body was sprayed with 300 times liquid to spray silkworm body, and 500 times of liquid was added to feed to prevent the fly larvae from harm. The fourth is to strengthen the management of clusters. Vigorously promote automated clustering technology. The specific method is: larvae developed neatly, see 5% to 10% of silkworm silkworms, according to each silkworm species with 4-6 stripping off the cold water even mixed mulberry leaves 20 to 30 kg (4 to 6 1 to 1.5 pounds of water), feeding silkworms at 10 to 12 o'clock in the evening, and then no longer giving mulberry leaves. The next morning at 10 to 12 o'clock, sprinkle some straw or silkworm nets on silkworms, plastic clusters, or clusters, etc. The clusters were placed on silkworms and the mature silkworms were automatically bunched together. After the clusters, the ventilation and dehumidification of the cluster rooms shall be enhanced (conditionally using a fan to remove moisture), so that the cluster rooms, the clusters, and the environment will be dried, and the yield and quality of the silkworm cocoon will be improved, so as to ensure the stable yield and high yield in summer and autumn.
