Rice seedling culture substrate pretreatment method using auricularia fuscosuccinea fungus chaff as raw materials

Abstract

The invention relates to a rice seedling culture substrate pretreatment method using auricularia fuscosuccinea fungus chaff as raw materials, and belongs to the technical field of agriculture. The invention aims at providing the rice seedling culture substrate pretreatment method using auricularia fuscosuccinea fungus chaff as raw materials with the characteristics that sulphuric acid with the proper concentration and quantity is used for pretreating the auricularia fuscosuccinea fungus chaff; bacterial agents are further added for thoroughly decomposed fermentation, so that the thoroughly decomposed time is shortened; the ammonia volatilization in the thoroughly decomposed process is reduced. The method comprises the following steps of raw material treatment, pretreatment, thoroughly decomposing and pile turning. A method of adding a sulfuric acid solution is used during the rice seedling culture substrate pretreatment is used. The method has the advantages that the operation is simple and convenient; sulfuric acid can be easily bought and used; the popularization and the popularization are convenient.

Description

technical field [0001] The invention belongs to the field of agricultural technology. Background technique [0002] The rapid development of my country's edible fungus industry has made my country the world's largest producer of edible fungi and at the same time produced a large amount of agricultural waste, namely fungus chaff. The current method of processing fungus chaff is mainly incinerated and discarded, which not only pollutes the environment but also wastes resources. Therefore, it has become an urgent problem to effectively utilize the fungus chaff resource and solve the pollution caused by waste dumping. [0003] Mushroom chaff contains high lignin, cellulose and hemicellulose and other difficult-to-use substances, which are not suitable for direct use in rice seedling cultivation. It needs to be decomposed to make its physical and chemical properties meet the requirements of rice seedling cultivation. In order to shorten the decomposing time, improve the physical...

Problems solved by technology

However, the previous acidification treatment is generally for the purpose of composting. During the composting process, acidic substances such as sulfuric acid or superphosphate are added at the same time as the fermentation agent or after adding the inoculum. The amount of acidic substances added is small and the concentration is low. To reduce the volatilization of ammonia, but without the effect of cracking lignin and cellulose, and because the acid concentration is not suitable for microbial activities, it generally reduces the decomposing speed and prolongs the decomposing time. In addition, if the added acid concentration is too high, after decomposing The acidity of the organic fertilizer will not meet the relevant fertilizer standards (the acidity standard of general organic fertilizers is pH5.5-8.5)

However, the pH required for the seedling substrate is low (pH4.5 or so). Both the traditional soil seedling substrate and the seedling substrate after decomposing wastes need to be acidified before rice seedlings can be grown. The acidification treatment before traditional seedlings requires high technical essentials. Difficult for farmers to master and increase labor costs
