Description

一种养蚕废弃物的循环利用方法A method for recycling sericulture waste 技术领域technical field
本发明属于家蚕养殖技术领域，具体涉及一种养蚕废弃物的循环利用方法，可以提高资源的利用率，减少废弃物对环境的污染。The invention belongs to the technical field of silkworm breeding, and in particular relates to a method for recycling sericulture wastes, which can improve the utilization rate of resources and reduce environmental pollution caused by wastes.
背景技术Background technique
家蚕（ Bombyx mori L.）在我国已经被人工驯养8500多年，属鳞翅目蚕蛾科完全变态昆虫，世代包括卵、幼虫、蛹和成虫（蛾）四个虫态。家蚕的四个虫态发育不同，体内外表征也不一样：卵是胚胎发育阶段，幼虫是从外界摄取营养的阶段，蛹是完成幼虫到蛾变态的过渡阶段，成虫是完成繁殖后代的阶段。由于家蚕的幼虫需要从外界摄取大量的营养，家蚕的饲养是蚕业生产中最重要的一个环节。 The silkworm ( Bombyx mori L.) has been domesticated in China for more than 8,500 years. It belongs to the complete metamorphosis insect of Lepidoptera Bombyridae, and its generations include egg, larva, pupa and adult (moth). Bombyx mori has four different stages of development, and its internal and external representations are also different: egg is the stage of embryonic development, larva is the stage of absorbing nutrients from the outside world, pupa is the transition stage from larvae to moth metamorphosis, and adult is the stage of complete reproduction of offspring. Since the larvae of the silkworm need to absorb a large amount of nutrition from the outside world, the rearing of the silkworm is the most important link in the sericulture production.
家蚕幼虫饲养周期大约25天，需要饲喂大量桑叶，1张蚕种（25000粒）需要新鲜桑叶约650kg，可以产生40kg～45kg的新鲜蚕茧，加上焦糠、石灰等辅料可生产的废弃物700～705kg，主要包括蚕粪、剩余桑叶、病蚕和死蚕、弱小蚕和蚕药。由于废弃物中含有病蚕，不提倡将蚕粪直接用于农田当作肥料，原因是病原的扩散可能会影响蚕病的传播；另外，养蚕过程中大量使用石灰和甲醛类蚕药，直接应用于农田，会引进土壤理化性质发展改变。随着养蚕规模化推进，废弃物的随处排放，严重影响生态环境，废弃物再利用成为迫切需要解决的问题。The feeding cycle of silkworm larvae is about 25 days, and a large amount of mulberry leaves needs to be fed. One silkworm egg (25,000 grains) needs about 650kg of fresh mulberry leaves, which can produce 40kg-45kg of fresh silkworm cocoons, which can be produced with auxiliary materials such as coke bran and lime. The waste is 700-705kg, mainly including silkworm excrement, remaining mulberry leaves, diseased and dead silkworms, weak silkworms and silkworm medicine. Because the waste contains diseased silkworms, it is not recommended to directly use silkworm manure as fertilizer in farmland, because the spread of pathogens may affect the spread of silkworm diseases; When applied to farmland, it will introduce changes in the physical and chemical properties of the soil. With the advancement of large-scale sericulture, wastes are discharged everywhere, seriously affecting the ecological environment, and the reuse of wastes has become an urgent problem to be solved.
另一方面，传统的养蚕过程中需要使用焦糠（炭化的稻壳），主要用于蚕座的干燥和隔离，喂蚕前使用是隔离剩余叶、蚕粪和病蚕等，保证家蚕吃到新鲜叶，也利于蚕座保持干燥，也利于防治蚕病；除沙前使用焦糠，可以驱使家蚕爬到蚕网上，发挥隔离的作用；新鲜的石灰还可以和焦糠混合使用，一般按3∶7比例，俗称“三七糠”，除了具有隔离的作用外，还可以杀灭家蚕病毒。目前稻壳主要用于畜禽饲料的生产，导致焦糠的价格逐年上升，有些蚕区由于价格高再放弃使用，也迫切需要寻找焦糠的替代品。On the other hand, in the traditional silkworm rearing process, coke bran (carbonized rice husk) is mainly used for drying and isolating silkworm seats. Fresh leaves are also beneficial to keep the silkworm seat dry and prevent silkworm diseases; using burnt bran before sand removal can drive silkworms to climb to the silkworm net to play the role of isolation; fresh lime can also be mixed with burnt bran, generally according to The ratio of 3:7, commonly known as "notoginseng bran", not only has the function of isolation, but also can kill silkworm virus. At present, rice husk is mainly used in the production of livestock and poultry feed, which leads to an increase in the price of coke bran year by year. Some silkworm areas give up using it because of the high price, and urgently need to find a substitute for coke bran.

The large-diameter carbonized material of the sieve is applied to the 4-5 instar silkworm.
从蚁蚕到上蔟，家蚕饲养过程中每龄起蚕使用防僵粉（多聚甲醛散）防治僵病，蚕座采用100kg上述炭化物进行吸湿和隔离（其他与常规饲养一致），除沙后收集所有废弃物。From ant silkworms to upper sacks, silkworms at each age in the silkworm breeding process use anti-stiffness powder (paraformaldehyde powder) to prevent and control stiffness, silkworm seats use 100kg of the above-mentioned carbonized material for moisture absorption and isolation (others are consistent with conventional breeding), after sand removal Collect all waste.
应用效果评价：一张蚕种的蚕茧产量为43.2kg，发病率为0%，虫蛹率98%，生产有害垃圾0kg，购买焦糠0kg。Application effect evaluation: the cocoon output of one silkworm egg is 43.2kg, the disease incidence rate is 0%, the pupa rate is 98%, the production of harmful waste is 0kg, and the charcoal chaff is purchased 0kg.
对比例不采用炭化物和焦糠的应用评价。The comparative example does not use the application evaluation of charcoal and coke bran.
家蚕饲养过程中每龄起蚕使用防僵粉（多聚甲醛散）防治僵病，蚕座不采用措施进行吸湿和隔离（其他与常规饲养一致），收集所有废弃物，湿重约600kg。During silkworm rearing, anti-stiffness powder (paraformaldehyde powder) was used to prevent and control stiff silkworms at each instar. The silkworm seat did not take measures to absorb moisture and isolate (others were consistent with conventional rearing). All waste was collected, with a wet weight of about 600kg.
一张蚕种的蚕茧产量为35.1kg，发病率为8%，虫蛹率92%，生产有害垃圾600kg，购买焦糠0kg，生产可再利用炭化物0 kg。The cocoon output of one silkworm egg is 35.1kg, the incidence rate is 8%, the chrysalis rate is 92%, the production of harmful waste is 600kg, the purchase of coke chaff is 0kg, and the production of reusable charcoal is 0kg.
