Autumn silkworm: fine tube culture, silkworm breeding, strong autumn temperature is very suitable for the physiological requirements of silkworm, is a good season for feeding multi-filament silkworm varieties. Keeping good autumn silkworms mainly focuses on the following four steps:
First, thorough disinfection, cut off the pathogen. After more batches of silkworm rearing in the first half of the year, the accumulation of pathogens increased and the chance of infection increased. Therefore, before raising the silkworm, we must do a good job of comprehensive disinfection and prevent disease. Can be used to disinfect the silkworm silkworm house, mulberry room, diverticulum and surrounding environment with a net disinfection, 1% available chlorine bleach solution, or a mixture of 2% formaldehyde and 0.5% lime. Use about 150-200 grams of liquid per square meter of area and keep it moist for half an hour after spraying. The use of formaldehyde disinfection, to seal the doors and windows for 24 hours to play the role of disinfection and disease prevention. To disinfect and prevent disease, we must not only disinfect the silkworm silkworm house, but also ignore the disinfection of silkworms and silkworms, as well as the disinfection of sporadic utensils such as silkworm nets and silkworm chopsticks. In short, the disinfection and disease prevention work must be carried out throughout the entire process of sericulture, and the regulations should be strictly followed. The preparation of pharmaceuticals should be accurate and the spraying should be uniform, leaving no dead ends. Diseased silkworm and silkworm feces should be properly handled to prevent the spread of pathogenic bacteria.
Second, ground pipe Fertilizer, attack Sang promote silkworm. After the beginning of autumn, the yield of mulberry leaves gradually decreased from the peak period, and often encountered the effects of drought, and the mulberry trees grew slowly. In addition, after the first half of the sun and rain and many batches of picking, nutrient consumption has been large, mulberry has been solid, solid, weeding, loose soil in time, improve soil looseness and water conservation fertility. At the same time, it is necessary to carry out the mulberry tree's branching or buckling to promote the emergence of new mulberry branches; increase fertilizing materials, supplement nutrients, achieve mulberry production and fertilizer, organic fertilizer combined with chemical fertilizers, diligent application of thin application, nitrogen, phosphorus and potassium application . 667 square meters of farmland fertilizer 1500 kilograms, 10 kilograms of urea and 25 kilograms of compound fertilizer were applied in two separate batches. 0.5% to 1% urea can also be used for extra-root fertilizer, increasing fertilizer and water, enhance tree vigor and improve leaf quality. When autumn falls are encountered, irrigation or water-spraying methods are used. Conditionally available straw or weeds cover the mulberry land to reduce overgrown weeds and maintain soil moisture, giving full play to the effects of fertilization. The implementation of attacking mulberry promotes silkworms, diligently manages to increase fertilizers, and promotes the mulberry tree to continue its vigorous growth. Only branches and leafy leaves, only Sangdo, can raise more silkworms, produce more quail, and have higher yields.
Third, plan to raise, balance silkworm. First of all, according to the growth of the mulberry, the amount of mulberry plans to set silkworm breeding, do a good balance of silkworm, to prevent the few rearing mulberry silkworm or overdose, causing unnecessary waste. Second, we must adopt good mulberry leaves. After the autumn, the climate turns to dryness. The mulberry leaves have low water content and are easily withered. It is better to use more water in the morning, store water with appropriate water, use bamboo storage for juvenile silkworms, use stacked storage for large silkworm mulberries, and stack with thin films. Cover and maintain the freshness of mulberry leaves. Third, to save the use of mulberry, we must master the principle of feeding young leaves at a low feeding age for each larvae, and give more sang to the principle of plentiful feeding, so that good mulberry satiety is not wasted, saves mulberry sericulture, and increases revenue.
Fourth, improve the environment, fine management. After the “summer heat” passed, the temperature began to fall, but the temperature remained unstable. Therefore, the “Autumn Tiger” with high temperature and high fever should be noticed in the early stage of the autumn silkworm. To enhance ventilation and cooling. The silkworm house should take measures such as covering the pergola around it, opening the sparse silkworm seat, spraying the well water, adding fresh water and so on, and doing a good job of cooling and preventing heat. In the later period, it is necessary to do a good job of warming and moisturizing. According to the weather characteristics of “a rainy season”, a hot day and a cool night, and a large temperature difference between day and night, pay attention to “five more cold” to prevent sudden temperature fluctuations and timely adjustments to keep the silkworm room in the 25 °C ~ 28 °C, wet and dry 2 °C ~ 2.5 °C, to avoid room temperature fluctuations induced silkworm disease. When drying at low temperature, it is necessary to properly heat and warm up, add boiling water to the furnace and moisten the water, and pay attention to open air. Large silkworms are reared slowly or not, and raising of “cold sinus” silkworms is avoided, silkworm diseases are induced, and the yield is reduced.
While grasping the improvement of feeding links, it is necessary to meticulously manage intensive care, and the saying goes, "Learn to raise 70% of silkworms." After receiving the ants, special persons shall be housed in separate rooms for proper sleeping and handling. If they do not meet one another, they shall be arrested and brought up in time, fed in batches, satiety, sleep, and sleep, and the weak and small silkworms will be eliminated to feed the young silkworms. Off, lay the foundation for raising a good silkworm. Choose good mulberry leaves, keep the leaf quality fresh, ground thin feeding, good mulberry satiety, appropriate increase in the number of sang and the mulberry amount of the fifth instar period, so that silkworm fully eaten, uniform growth and development, Robust and disease-free, the silk thread is well developed, and the silkworm grows large, yielding much more.
