Embodiment 1

[0030] Example 1 An organic nutrient soil improvement agent is mixed with agricultural solid waste biogas residue, chicken manure, and rapeseed cake at an air-dry weight ratio of 0.30:0.30:0.09, fermented, and sieved, and 30 kg of soil improvement agent is added to each ton of the soil improvement agent. CO(NH 2 ) 2 , 50kg NH 4 h 2 PO 4 、40kgK 2 SO 4 , 8kg polyacrylamide powder, 25kg hydrated lime powder mixed.

[0031] Its specific production method is as follows: First, mix the various agricultural solid wastes according to the proportion, add water to make the water content reach 60-65% (just hold water droplets to leak out), mix well, and pile them into 1.0-1.20m (thick trapezoidal , stack and ferment for 7-10 days under the condition of sunlight temperature of 32-35 °C, turn over once when the temperature in the stack reaches 60-65 °C, and then turn over once at intervals of 15-20 days, add a small amount of water each time ; then ferment for 90-100 days and then a...

Embodiment 2

[0032] Example 2 An organic nutritional soil improvement agent is mixed with agricultural solid waste biogas residue, chicken manure, and rapeseed cake at an air-dry weight ratio of 0.60:0.60:0.20, fermented, and sieved, and 31 kg of soil improvement agent is added per ton of the soil improvement agent. CO(NH 2 ) 2 、51kg NH 4 h 2 PO 4 、41kgK 2 SO 4 , 10kg polyacrylamide powder, 26kg hydrated lime powder mixed.

[0033] Its concrete production method is with embodiment 1.

Embodiment 3

[0034] Example 3 An organic nutritional soil improvement agent is mixed with agricultural solid waste biogas residue, chicken manure, and rapeseed cake at an air-dry weight ratio of 0.40:0.40:0.10, fermented, and sieved, and 31 kg of soil improvement agent is added per ton of the soil improvement agent. CO(NH 2 ) 2 、51kg NH 4 h 2 PO 4 、41kgK 2 SO 4 , 10kg polyacrylamide powder, 26kg hydrated lime powder mixed.

[0035] Its concrete production method is with embodiment 1.

Abstract

The invention relates to an organic and nutrient soil improving agent. The soil improving agent is characterized by being prepared by mixing agricultural solid wastes, such as biogas residue, chicken manure and rapeseed meal in an air drying ratio of 0.30-0.60:0.30-0.60:0.09-0.20, fermenting the mixture, sieving the fermented mixture, adding 30-31 kilograms of CO(NH2)2, 50 to 51 kilograms of NH4H2PO4, 40 to 41 kilograms of K2SO4, 8 to 10 kilograms of polyacrylamide powder and 25 to 26 kilograms of hydrated lime powder into the sieved mixture based on 1 ton of soil improving agent and mixing the components. Since the agricultural solid wastes are used, the aim of improving the physicochemical property and the environment condition of soil is fulfilled and the water storage function and organic matter content of the soil can be effectively enhanced.

Description

technical field [0001] The invention relates to the field of agricultural soil, in particular to an organic nutrient soil improvement agent. Background technique [0002] my country's planting industry has a long life, the amount of chemical fertilizers used in farmland is increasing year by year, the amount of organic fertilizers is seriously insufficient, and the amount of chemical fertilizers N and P 2 o 5 Input amount and organic fertilizer N, P 2 o 5 The ratio of the total input is 1:0.28. The improvement of crop yield mainly depends on the application of chemical fertilizers. The long-term and large-scale application of chemical fertilizers will continuously consume soil organic matter, resulting in soil compaction and compaction, and weakened water storage function. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an organic nutrient soil improvement agent that improves the water storage function and or...
