Poisoning causes and prevention of silkworm
In the silkworm silkworm egg incubation period and the small age of twelve, the Jamsil temperature is low, the need for heating. If the use of coal heating products, nor on the coal stove exhaust pipe, the gas generated by the toxic gases (primarily sulfur dioxide, hydrogen sulfide, carbon monoxide, etc.) t can cause poisoning silkworm silkworm eggs or small. Silkworm eggs in the incubation period t prone to poisoning death of a small silkworm eggs or hatching missing poisoning,Burberry, breast enlargement, spit the water, tail contraction, and soon died, most of his body rot, skin break out after the Hang ■ brown slop, and some dried up on prevention and education to promote Kangchuang silkworm and ground into flames, gas lights, solar heating methods to avoid toxic gases if Jamsil like heating with coal stove, be sure to install the exhaust - pipe, regular breathing. To keep the air fresh and Jamsil. Once a gas poisoning. In addition to immediately Jamsil for ventilation, but also the silkworm silkworm eggs or small air flow into place to alleviate the symptoms of poisoning second exhaust gas poisoning. Jamsil as close to the body color of dirty, silkworm thin, gradually shrinking as large silkworm died of poisoning, but also to make links between the film stack up,Abercrombie Nederland, easy bleeding and some raw black circular spots, after the death of the body is dark brown and shriveled. prevention is required to do the factory exhaust recycling, pollution reduction step on the mulberry leaves the new extension should stay away from a plant of the mulberry plant waste, to avoid the harmful effects of gases on the mulberry not contaminated by the toxic gas to feed silkworms mulberry leaves . to prevent poisoning after eating. Third, silkworm pesticide poisoning pesticide poisoning in three circumstances, exposure to pesticides, inhalation of pesticides and pesticide-contaminated food under the mulberry leaves after the poisoning. crawling around with poisoned silkworm, silkworm body spasm atrophy,Ralph Lauren, a lot of spit liquid, Qu, some even holding fecal leakage, rectal prolapse, etc. soon die of poisoning serious silkworm, silkworm light virtual poisoning of recovery possible. trace of poisoning in the late fifth instar of the silkworm, when no obvious symptoms, but Shangcu,Ed Hardy italia A New Perleidiform (Actinopterygii, often become an silkworm cocoon. prevention is not to indoor pesticides stored in the silkworm. silkworm body in order to avoid inhalation of pesticide exposure to pesticides and the proper use of pesticides silkworm. try not to do with pollution, pesticide contamination of mulberry mulberry leaves to feed a suspected cause of 39 a Silkworm anti-virus application and how to cultivate the agricultural hall in Liaoning Province grafted mulberry crops at Jiang Guiliang to worry by the varieties of mulberry trees or Gao Mao, branches grafted onto seedlings, or root, mulberry cultivation of grafted seedlings, - to maintain the good elements of the Jie, rapid growth and development, seedling short time, high leaf yield, leaf quality is good while, but with strong roots of seedlings feast, and enhance the lives of power plants 1. scion collection and storage of mulberry scions should be selected for local climate conditions, high yield performance, business, mulberry 'good quality, substantial branches, buds and full, no pest damage, about 1 cm in diameter by the variety of excellent year-old branches. scion Sang in maternal the same, and the young spring cutting to cut mulberry fine clipping on the grafted scion scion number according to the thickness and grafting techniques to determine the degree of proficiency. with bags of connection, for example, is generally grafted 10000 millet seedlings each, Fan equipment scion 75-100 kg. grafting unskilled, thick branches should prepare some more. scion collected in the top 20 non-grafted or about, the province in late March or early April. scion to be taken back possession. possession of scion scion should pay attention to fresh, and to properly control the development of the scion so slightly later than the anvil technique is appropriate. storage temperature should be maintained at 51O ℃, relative humidity maintained at about 7O. scion to avoid direct sunlight. to heat , anti-dry, not moldy, not germination. 2 grafting methods when used as rootstock mulberry tree begins to flow sleep, the cortex and seedling quality of the Department of easy to squeeze open surgery, they can be grafted. the province is generally in April early May to late graft mulberry many ways there bags then, budding, abdominal access, the sheath then Qian. velvetleaf bags will be connected in operation, high efficiency, fast seedling, seedlings for large complex. silkworm, such as feeding subject try feeding harmless after use. discover poisoning should promptly identify the cause, withdraw immediately to the silkworm Block lime powder, isolated toxins, to feed fresh mulberry leaves. silkworm of mild poisoning, can be rinsed clean in cold water or tea Ling, vomiting, to recovery. and to strengthen management and reduce toxic damage. Fourth, the poisonous hairs poisoning. silkworm caterpillar contact or eat the poisonous hairs under the mulberry, 4O cause mechanical injury and chemical toxicity profile, especially for small silkworm great impact. Small caterpillars mulberry silkworm head hair drug poisoning, loss of appetite pause, silkworm wilt small, and soon died. prevention is careful control mulberry pests, to prevent the elimination of Sang Sang {caterpillars and caterpillars mulberry silkworm caterpillars molt mixed seat, especially small Block does not adopt mulberry silkworm and mulberry insect population molting caterpillars mulberry leaves attached to prevent hair damage poisonous caterpillars mulberry silkworm.
