Description
Technical field
The present invention relates to technical field of biological fertilizer, more particularly to a kind of stalk brick and its preparation for edible fungus culturing
Method.
Background technology
China is agricultural production big country, the annual substantial amounts of agricultural wastes-stalk of output.According to statistics, the whole nation is every year because of agriculture
Nearly 900,000,000 tons of stalk total amount caused by industry production activity, occupies first place in the world.Due to country labor force transfer and turn of tillage method
Become, the comprehensive utilization ratio of stalk is relatively low, most of stalk by on-site incineration or throw out without care disorderly abandon, resulting agricultural non-point source pollution
Problem and problem of environmental pollution have been subjected to more and more paying attention to, and government puts into effect multinomial policy and accountability mechanism and forbids straw in succession
Stalk burns, and supports to promote the comprehensive utilization technique such as straw feed and Fertilizer Transformed energetically.
Develop and use straw biological fertilizer, to stalk comprehensive utilization and will realize that ecologic breeding has far-reaching influence.
At present, agricultural straw resource is widely used in the cultivation of edible mushroom, and planting type mainly has the side such as bed cultivation, pocket type cultivation
Formula.At present, more commonly used planting type is to use bag cultivating, and pocket type cultivation is simple and convenient.But existed using pocket type cultivation
Problems with：1st, the packed plastic material used is generally high density polyethylene (HDPE) or polypropylene, can produce a large amount of white garbages, place
Reason is difficult, degradation cycle length, causes environmental pollution；2nd, easily occur phenomena such as pack is uneven when compost packs, influence follow-up
The growth of edible fungus cluster；3rd, because the polybag used is relatively thin, in handling process is transported, breakage easily occurs, and packed
Cheng Zhong, stalk puncture polybag, cause compost to spread damage；4th, because packed section is elliptoid, training is put after being inoculated with strain
When supporting, it should be noted that the end face of inoculation is put upward, avoid downwards putting inoculation position, so as to reduce production efficiency.Therefore, more
It is good using agricultural crop straw come culturing edible fungus, raising production efficiency and economic well-being of workers and staff, and reduce environmental pollution be still worth into
One step research.
