Studies On Ecological Synthesis Utilization Of Crop Straw

We studied the multipurpose-use of crop straw to maximize resource utilization. At last , we ,surrounding the multipurpose-use of crop straw ,established a benign zoology chain : edible fungi production—vegetable organic ecotype soil less cultures-soil improvement.This technology realized multilevel-use of crop straw : crop straw were primarily used to edible fungi production, secondly the residues after edible fungi production were used to vegetable organic ecotype soiless cuilture, lastly the abandoned materials were used to improve soil.This technology not only could effectively assimilate crop straw, produced benefits by mushroom production, but also could tackle the problem of continuous gropping in protected culture, increase vegetable production and marketabley increase the quality.According to the special requirement of multilevel-use of crop straw, we carried on the study integrately : edible fungi production, vegetable,organic ecotype soiless cuilture and soil improvement. The result indicated that:1, Oyster mushroom production with crop straw as stroma. Different ratio of crop straw had different biology transform ratio, the mixture of corn stalk, cornstock and cob produced the best biology transform ratio, the best economy benefits and realized the utilization of crop straw.2, The results indicated that: soiless culture with mushroom residues instead of grass peat was feasible. Although the production had somewhat decrease, the cost of soiless culture stroma decreased to a large scale, as a result , the yield/devotion ratio improved greatly. The mixture ratio had comparable great ifluence, the best mixture in our city was: mushroom: residues: slags=6:4. Sand could be a substitute for slag where slag were absent ,the ratio: mushroom residues : sand =6:4.3, Vegetable organic ecotype soiless cuilture with mushroom residues as culturing media could not only realize the reulization of crop straw , but also greatly lighten plant diseases and insect pests, reduce pesticide residue,...
