Abstract

The invention provides a basic farmland soil modifying agent, belonging to the technical field of fertilizer production. The modifying agent is prepared by adopting grass carbon, dried pine straw, vermiculite, natural zeolite, humus soil, well-rotted farmyard manure, aluminum sulfuric acid, zinc sulfuric acid and manganese sulfuric acid as raw materials. The preparation method is to crush the grass carbon, the dried pine straw, the vermiculite and the natural zeolite and mix with other raw materials to be uniformly stirred. The basic farmland soil modifying agent can loosen soil of basic farmland, improve the physical character and chemical character of the basic farmland soil, promote crop growth, improve utilization rate of fertilizer, and increase yield of crops.

Description

Alkaline Farmland Soil Conditioner

technical field

The invention belongs to the technical field of fertilizer production and is a soil improver.

technical background

In the semi-arid area in the western part of the Northeast Plain, there are a large amount of alkaline farmland composed of chernozem and light alkaline soil. The alkaline farmland soil has high salt content, hard soil, poor water storage and air permeability; the soil organic matter content is low and the nutrient content is low. ; The degree of salinization of alkaline farmland is relatively high, and the natural fertility and potential fertility of the soil are low, forming a medium-low yield field. There is no ideal solution yet.

Contents of the invention

The technical problem to be solved by the invention is to disclose an alkaline farmland soil improver so as to improve the properties of the alkaline farmland soil.

The technical solution to be solved in the present invention is to use peat, dry pine needles, vermiculite, natural zeolite, humus, decomposed farmyard manure, aluminum sulfate, zinc sulfate and manganese sulfate to make alkaline farmland soil improver, the weight ratio of the above raw materials for:

Peat 33-37

Pine needles 11-14

Vermiculite 8-10

Natural Zeolite 7-9

Humus 10-13

Decomposed farmyard manure 16-22

Aluminum sulfate 1.5-2.5;

Zinc sulfate 0.005-0.015

Manganese sulfate 0.005-0.015

The preparation method is that peat, dry pine needles, vermiculite and natural zeolite are pulverized, and then mixed with other above-mentioned raw materials and mixed evenly.

The optimal weight ratio of above-mentioned raw materials is:

Peat 35

Pine needles 12.6

Vermiculite 9

Natural Zeolite 8

Humus 12

Decomposed farmyard manure 21.38

Aluminum Sulfate 2

Zinc sulfate 0.01

Manganese sulfate 0.01.

The application method of this improver is to apply 20,000 kg of improver per hectare of farmland, and after the soil surface is evenly applied, rotary tillage is inserted into the soil 20 cm and mixed with the soil evenly; Then bury it in a ridge.

After applying the improver, soil bulk density decreased by 5.5%, soil hardness decreased by 1.8%, solid phase decreased by 4.6%, liquid phase decreased by 8.9%, gas phase increased by 26.3%, and corn yield increased by 14.3%. The alkaline hydrolysis N content in the soil increased by 6.3%, the available P increased by 9.8%, the available K increased by 14.5%, the organic matter content increased by 20.4%, and the soil pH decreased by 6%.

This product is a soil conditioning nutrient improver that can improve the physical and chemical properties of alkaline farmland soil. Nutrient elements and nutrient coordinating substances needed by plants are added, which can improve soil, increase fertilizer efficiency and protect the environment.

This product has the following functions: loosen the soil of alkaline farmland, improve the physical and chemical properties of alkaline farmland soil, promote crop growth, improve fertilizer utilization rate, and increase crop yield.

The product has the characteristics of rich raw material resources, simple manufacturing process, convenient field application, low production cost, and no toxic and side effects.

Detailed ways

Take 35 kg of peat, 12.6 kg of dry pine needles, 9 kg of vermiculite and 8 kg of natural zeolite, and then mix them with 12 kg of humus, 21.38 kg of decomposed farmyard manure, 2 kg of aluminum sulfate, 0.01 kg of zinc sulfate, and 0.01 kg of manganese sulfate , mixed evenly.
