Abstract
The invention relates to the technical field of straw compost after-ripening accelerators, and in particular relates to a straw compost after-ripening accelerator and a use method thereof. The accelerator comprises the following components by weight: 10-20kg of paper-making mud, 0-10kg of cellulose, 5-10kg of betaine and 2-5kg of arginine. The use method comprises the following steps: adding an urotropine modifier in the stage of converting a high temperature to a low temperature in a conventional compost method; and adding the after-ripening accelerator and a surfactant to carry out compost for 10-15 days at room temperature. By using the after-ripening accelerator, the decomposition rate of straw cellulose is above 50%, the increase production effect generated by using the compost product on crops is obvious, and the after-ripening accelerator has the effects of improving soil and enhancing the quality of agricultural products.
Description
Technical field
The present invention relates to the straw compost processing technology field, a kind of straw compost after-ripening accelerator and using method thereof specifically are provided.
Background technology
China is grain-production big country, is also stalk big producing country.Strengthening the agricultural crop straw comprehensive utilization, is key subjects of China's new stage agricultural and rural economy development.But the peasant often adopts the mode of burning to process, and it is very serious that stalk is thrown out the phenomenon of disorderly abandoning without care, causes the serious wasting of resources and has aggravated pollution to environment, has become the common problem that needs to be resolved hurrily in China's agriculture and countryside environmental construction.Strengthening the fermentation maturity of stalk and utilize technical study, is that stalk resource effectively utilizes and adapt to the better approach of agricultural sustainable development needs, both has been conducive to the reasonable utilization of resource, can extensively ward off the source of manure again, improves soil productivity, reduces and pollutes.
Because Mierocrystalline cellulose, hemicellulose and xylogen degradation speed in composting process in stalk is slow, adopt traditional compost method length consuming time, cost is high, is unfavorable for again the preservation of nitrogen nutrient, has become the main bugbear in composting technology.The inoculation cellulose-decomposing bacteria, and select suitable condition to become the important technology of straw compost, can present the variation of low temperature-high temperature-low temperature due to temperature of charge in composting process, cellulose-decomposing bacteria is difficult to survive under hot conditions, existing patent and bibliographical information often have certain effect at compost initial stage inoculation cellulose-decomposing bacteria at low thermophase, just are greatly affected but enter the hot stage decomposition of cellulose.Therefore, straw compost often needs time of growing, and simultaneously, the degree of becoming thoroughly decomposed is not high, and the land for growing field crops result of use is greatly affected.
Summary of the invention
The present invention be directed to above deficiency, a kind of straw compost after-ripening accelerator and using method thereof are provided, when it has solved the compost method that adopts routine, the cellulose decomposition rate is low, and the compost product is difficult to reach cellulolytic problem.
The technical solution adopted in the present invention is as follows:
A kind of straw compost after-ripening accelerator, its component includes: paper mill sludge 10-50kg, cellulase 0～10kg; Trimethyl-glycine 5～10kg; Arginine 0～10kg.
Component according to weight ratio is: paper mill sludge 10-20kg; Cellulase 2～6kg; Trimethyl-glycine 6～8kg; Arginase 12～5kg.
A kind of using method of straw compost after-ripening accelerator, its method steps comprises:
A, add urotropine 5-20kg in every cube of compost, the turning mixing was placed 4-5 days;
B, add paper mill sludge 10-50kg, cellulase 0～10kg; Trimethyl-glycine 5～10kg; Arginine 0～10kg; Tensio-active agent 5-10kg places that after 10-15 days, material becomes thoroughly decomposed.
Step B need to carry out under lower than the prerequisite of 45 ℃ at the compost heap temperature that satisfies steps A.
The method that step B adopts turning mixing or layering to add.
The paper mill sludge that adds in step B is 10-20kg, and cellulase is 2～6kg, and trimethyl-glycine is 6～8kg, and arginine is 2～5kg.
Tensio-active agent is one or both in Yelkin TTS, Natvosol, cyclodextrin, Lalgine.
Compared with the prior art, the present invention has following technical superiority:
1, a kind of straw compost after-ripening accelerator of the present invention, contained material is nontoxic, crop is had the effect of growth regulation;
2, compare with conventional compost, the formula that the present invention relates to uses when compost high temperature transfers low temperature to, and main purpose is to promote the decomposition of cellulosic material in stalk, thereby promotes becoming thoroughly decomposed of windrow.
Use a kind of straw compost after-ripening accelerator of the present invention, the stalk cellulose rate of decomposition can reach more than 50%, the obvious effect of increasing production that the composting product uses on crop, and straw compost after-ripening accelerator of the present invention also has improvement soil, the effect of raising quality of agricultural product.
