Embodiment Construction

[0013] The invention relates to a method for composting pure organic fertilizers by using straws, which includes selecting a place leeward to the sun, convenient for transportation, and close to water sources during the composting process, first leveling and compacting the ground to prevent fertilizer solution from seeping down, and taking wheat straw and rice stalks , corn stalks, sorghum stalks or mixed straws 60%, soaked with water the day before retting, it is advisable to squeeze water by hand, 30% of fine dry soil or pond mud, 10% of decomposed human and animal manure;

[0014] The steps are as follows: firstly spread a layer of sludge and turf with a thickness of about 15 to 20 cm on the ground as a bottom pad for absorbing infiltrating fertilizer;

[0015] 2. Spread a layer of 25-30cm thick straw on the basis of step 1, pour a layer of human and animal manure after being firm and compacted; spread a layer of 10-12cm thick fine dry soil or pond mud on the human and anima...

Abstract

The invention relates to a method for composting pure organic fertilizer by using straws. The method comprises the following steps: taking 60 percent of one of wheat straws, straws, cornstalks and sorghum stems or mixed straws, soaking the straws with water on one day before retting until water can be wringed, and taking 30 percent of fine dry soil or pond silt and 10 percent of composted human and animal excreta; firstly, laying a layer of sludge and turf with the thickness of 15 to 20 cm on the ground to serve as a bottom mat absorbing infiltrating fertilizer nutriments; secondly, laying a layer of straws with the thickness of 25 to 30 cm on the basis of the first step, treading, compressing and then sprinkling a layer of human and animal excreta; laying a layer of the fine dry soil or the pond silt with the thickness of 10 to 12 cm and laying the straws with the thickness of 25 to 30 cm on the fine dry soil or the pond silt; stacking upward layer by layer according to the operationuntil the height is 1.5 to 2 m; finally, sealing and storing for 20 to 25 days by using slime; and thirdly, turning over piles once after a mixture is retted for 20 to 25 days, and using the raw materials when the raw materials reach the black, rot and odor degrees. According to the method disclosed by the invention, natural resources are completely utilized for fermenting, so that the rotting cycle of the straws is shortened, and the straws can be retted even in winter; and the method becomes a novel method for producing high-quality organic fertilizer at present.

Description

technical field [0001] The invention relates to the production of organic biological fertilizers, in particular to a method for making pure organic fertilizers by using straws. Background technique [0002] There have been many patent documents for the production of organic fertilizers. A method of quick-rot composting organic fertilizer Application No.: 201210222147.6 Application date: 2012-06-29 A method of quick-rot composting organic fertilizer, involving agricultural production technology field, the specific composting process is: first soften the crop stalks, divide the softened crop stalks into three layers of mixed materials, and evenly add 0.1% of the crop stalk weight biological composting agent and 0.5% of the crop stalks to each layer of crop stalks For weight nitrogen-containing regulators, after layering stacking is completed, the stacked stacks are sealed with mixed mud and retting takes 20 days. The method of retting organic fertilizer is simple and fast, an...
