Problems solved by technology

About FeSO 4 In the research of additives, poultry manure is mainly used as compost material, but FeSO 4 There are few reports on the amount range of the dosage and its synergy with EM bacteria agent and urea to make additives, and there is no FeSO 4 In the application of simple straw composting, it can be seen that FeSO 4 How effective it is to promote the high-efficiency decomposition of straw deserves further study

Embodiment 1

[0017] 1 Materials and methods

[0018] 1.1 Test material

[0019] Peanut stalks are taken from the Red Soil Station in Yingtan City, Jiangxi Province, with a carbon content of 359.9g.kg -1 , Nitrogen 10.95g.kg -1 , Phosphorus 1.54g.kg -1 , Potassium 14.81g.kg -1 ;FeSO 4 It is an analytically pure chemical reagent; the test bacteria is a commercial EM bacteria stock solution.

[0020] 1.2 Test method

[0021] This experiment was set up without FeSO 4 control, and three levels of FeSO 4 Additives, a total of 4 treatments (Table 1), were cultured in an incubator with constant temperature and ventilation. First, put 80g of crushed peanut straw into a 500mL culture bottle; then, add 2% of the weight of the straw and 1% to 5% of FeSO 4 Additives are mixed evenly, and at the same time, in order to achieve the best C / N required by microorganisms, the C / N of the material is adjusted to 20~30 with 0.75% urea; finally, the water content of the mixed system is adjusted to 60~70%...

Embodiment 2

[0051] 1 Materials and methods

[0052] 1.1 Test material

[0053] The rice straw was taken from the Red Soil Station of Yingtan City, Jiangxi Province, with a carbon content of 403.8g.kg -1 , Nitrogen 6.37g.kg -1 , phosphorus 0.88g.kg -1 , Potassium 21.21g.kg -1 ;FeSO 4 It is an analytically pure chemical reagent; the test bacteria is a commercial EM bacteria stock solution.

[0054] 1.2 Test method

[0055] This experiment was set up without FeSO 4 control, and three levels of FeSO 4 Additives, a total of 4 treatments (Table 5), were cultured in an incubator at a constant temperature of 25-30°C with ventilation. First, put 80g of crushed rice straw into a 500mL culture bottle; then, add 2% of straw weight EM agent and 1%~5% FeSO 4 Mix the additives evenly, and at the same time, in order to achieve the best C / N required by the microorganisms, adjust the C / N of the material to 20~30 with 2.1% urea by weight of the straw; finally, adjust the water content of the mixed ...

Abstract

The invention provides an additive for accelerating crop straws to efficiently maturate and an application thereof. The weight of the straws is used as the reference; the weight of EM (Effective Microorganisms) fungus raw liquid accounts for 2% of the weight of straws; the weight of urea accounts for 0.75-2.1% of the weight of the straws; and the weight of FeSO4 accounts for 1-5% of the weight of the straws. According to the application of the additive for accelerating the crop straws to efficiently maturate, peanuts or rice straws are used as raw materials; EM fungus is selected as a fungicide for testing; the FeSO4 with different levels can be respectively added, so that the acceleration effect on the straw efficient maturation by the FeSO4 with the different levels can be researched in a constant-temperature and ventilation culture condition; and finally, a compost additive product is formed by properly proportioning the fungicide, the urea and a chemical matter FeSO4. The additive for accelerating the crop straws to efficiently maturate, provided by the invention, provides a suitable additive and suitable addition volume for an aerobic compost of the straws, so as to improve the circulation utilization of straw resources.

Description

technical field [0001] The invention belongs to the technical field of crop straw treatment, and in particular relates to an additive for promoting efficient decomposition of crop straw and its application. Background technique [0002] According to the survey, the annual unused straw resources in my country are about 215 million tons, accounting for about 1 / 3 of the amount of straw resources that can be collected. However, straw contains a lot of nitrogen, phosphorus, potassium and organic matter, and the discarded straw is the lost solid resource. , and making straw into organic fertilizer through composting technology is an effective means to deal with its surplus. Therefore, it is necessary to explore a set of high-efficiency straw decomposing technical solutions in order to alleviate the waste of straw and achieve the purpose of recycling agricultural resources. Studies have shown that additives can adjust the physical and chemical properties of compost, Mu Kejun et al [...
