Embodiment 1

[0020] Crush the cotton stalks into 1-10mm segments, add water to a water content of 60% according to the mass percentage, then add 2 kg of urea, 0.5 kg of superphosphate, 1 kg of gypsum, and 50 g of fermentation bacteria per cubic meter according to the volume ratio, and Mix evenly, and ferment in a sealed pile at an air temperature of 15°C; the sealed pile fermentation is carried out under a plastic film or straw curtain, and the pile is turned every 10 days after the start of fermentation. When turning the pile, add water to the water content of 60%. 40 days; the fermented composite bacterial agent used is Pseudomonas aeruginosa ( Pseudomonas aeruginosa ), Streptomyces albicans ( Streptomyces albus ) and Flavobacterium ( Flavobacterium mizutaii ) is prepared by mixing according to the weight ratio of 2:3:1; under the condition of full fermentation, the color of the crushed cotton stalks will change from light yellow to dark brown, and at the same time, the fermentation h...

Embodiment 2

[0022] Crush the cotton stalks into 1-10mm segments, add water to the water content of 80% according to the mass percentage, then add 3kg of urea, 1kg of superphosphate, 2kg of gypsum, and 100g of fermentation bacteria per cubic meter according to the volume ratio, and mix Uniform, sealed stacking fermentation at an air temperature of 40°C; the sealed stacking fermentation process and the fermentation compound bacterial agent adopt the method provided in Example 1, and the water content is replenished to 80% when turning over; in the case of full fermentation, the cotton straw pulverized The color of the mixture will change from light yellow to dark brown, and the fermentation heap of the pulverized material will no longer produce a musty smell. After the fermentation is completed, it can be spread to dry and then the substrate can be prepared.

Embodiment 3

[0024] Crush cotton stalks into 1-10mm segments, add water to 70% water content according to mass percentage, then add 2.5kg of urea, 0.6kg of superphosphate, 1.5kg of gypsum, and 80g of fermentation bacteria per cubic meter according to the volume ratio , and mix evenly, and ferment in a sealed pile at an air temperature of 30°C; the sealed pile fermentation process and the fermentation compound bacterial agent adopt the method provided in the above example, and the water content is replenished to 70% when the pile is turned; in the case of full fermentation, the cotton The color of the crushed straw will change from light yellow to dark brown, and at the same time, the fermentation heap of the crushed product will no longer produce a musty smell. After the fermentation is completed, it can be spread out to dry and then the substrate can be prepared.

Abstract

The invention discloses a method for producing a seedling raising substrate by using cotton straw and a substrate prepared with the same. The method comprises the following steps of: smashing cotton straw into sections of 10-50 millimeters; adding water till the water content is 60-80 percent according to mass percentage; adding 2-3kg of urea, 0.5-1kg of calcium superphosphate, 1-2kg of gypsum and 50-100g of fermentation inoculum into each cubic meter of substances obtained in the last step according to the volume ratio; mixing uniformly; and sealing, piling and fermenting at the air temperature of 15-40 DEG C, wherein the adopted compound fermentation inoculum is prepared by mixing pseudomonas aeruginosa, streptomyces albus and flavobacterium in the ratio of 2:3:1, and can be used by fermenting, airing in a scattered way and drying. In the method, a main raw material is derived from a large amount of waste cotton straw generated during the production of cotton, the raw material source is rich, a preparation process is simple, the aim of utilizing resources is fulfilled, and resource waste of cotton straw caused by direct smashing and returning to field can be reduced; and the method has a wide application value.

Description

technical field [0001] The invention relates to the technical field of agricultural substrate production, in particular to the technical field of a method for producing a seedling raising substrate with cotton straw and the prepared substrate. Background technique [0002] With the development of modern agriculture, the use range and amount of seedling substrates are very large, but the current seedling substrates are still mainly composed of peat soil, vermiculite, perlite, etc. These are non-metallic mineral resources and are non-renewable in the short term. Natural resources, natural reserves are limited, and for the purpose of environmental protection, they cannot be exploited and used without restriction; using solid organic waste to produce seedling substrates can not only protect limited natural resources, but also increase the utilization value of organic waste and create considerable economic benefits . [0003] Up to now, China's cotton planting area is about 6 mi...
