Embodiment 1

[0050] A method for compounding and applying green manure organic materials for improving soil fertility, comprising the steps of:

[0051] S1. Treatment of organic materials:

[0052] a. Put the crop stalks into the straw grinder for crushing treatment. The speed of the grinder is 600rpm, and the crushing process is 30min. Then, the crushed crop straws are immersed in the treatment solution. After 20kHz ultrasonic vibration treatment for 1h, the soaked crop Put the straw treatment liquid into the reactor, raise the temperature in the reactor to 100°C, raise the pressure in the reactor to 0.3MPa, maintain the temperature and pressure for 10 minutes, quickly release the pressure to normal pressure, filter out the crop straw and dry it After drying, the components and the corresponding weight percentages in the treatment liquid are: 0.2% sodium hydroxide, 2% ethylenediamine, 5% Tween, 0.6% decanoyl acetaldehyde, and the balance is deionized water;

[0053] b. Put decomposing ag...

Embodiment 2

[0062] A method for compounding and applying green manure organic materials for improving soil fertility, comprising the steps of:

[0063] S1. Treatment of organic materials:

[0064] a. Put the crop stalks into the straw grinder for crushing treatment. The speed of the grinder is 700rpm, and the crushing process is 35 minutes. Then the crushed crop straws are immersed in the treatment solution. Put the treatment solution of crop straw into the reactor, raise the temperature in the reactor to 110°C, raise the pressure in the reactor to 0.4MPa, maintain the temperature and pressure for 18 minutes, quickly release the pressure to normal pressure, and filter out the crop straw After drying, it is used for later use, wherein the components and corresponding weight percentages in the treatment liquid are: 0.25% sodium hydroxide, 2.5% ethylenediamine, 6% Tween, 0.7% decanoyl acetaldehyde, and the balance is deionized water ;

[0065] b. Put the decomposing agent, farm manure and ...

Embodiment 3

[0074] A method for compounding and applying green manure organic materials for improving soil fertility, comprising the steps of:

[0075] S1. Treatment of organic materials:

[0076] a. Put the crop stalks into the straw grinder for crushing treatment. The speed of the grinder is 800rpm, and the crushing process is 340min. Then, the crushed crop straws are immersed in the treatment solution, and after 50kHz ultrasonic vibration treatment for 2 hours, the soaked crops Put the straw treatment solution into the reactor, raise the temperature in the reactor to 120°C, raise the pressure in the reactor to 0.5MPa, maintain the temperature and pressure for 26 minutes, quickly release the pressure to normal pressure, filter out the crop straw and dry it. After drying, the components and the corresponding weight percentages in the treatment liquid are: 0.3% sodium hydroxide, 3% ethylenediamine, 7% Tween, 0.8% decanoyl acetaldehyde, and the balance is deionized water;

[0077] b. Put ...

Abstract

The invention discloses a green manure organic material combined application method for improving soil fertility, and belongs to the technical field of soil improvement. The method comprises the following steps: S1, treatment of organic materials; S2, planting of green manure; and S3, harvesting and turning over of green manure. The invention provides a green manure organic material combined application method for improving soil fertility. Soil organic matters, alkali-hydrolyzable nitrogen, rapidly available phosphorus, rapidly available potassium and soil microbial quantity are all higher than those of a basic soil sample after green manure organic material combined application by the method provided by the invention. The method is conducive to changing the physical and chemical properties of soil and improving the soil fertility, and the method is safe, environmentally friendly and beneficial to application and popularization.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a method for compounding and applying green manure organic materials for improving soil fertility. Background technique [0002] Green manure is the essence of traditional agriculture in my country. The cultivation and utilization of green manure crops has a long history and played a pivotal role in my country's agricultural production. The application of green manure can significantly increase the nitrogen content in the soil, because the green manure is fresh and tender, decomposes and mineralizes quickly after overturning, and can release nutrients quickly and timely for crops to absorb and utilize. While increasing the content of organic matter in the soil, green manure can increase the content of alkaline nitrogen, available phosphorus and available potassium in the soil, and can also reduce the soil bulk density, increase the porosity and water stabili...
