Soil conditioner for enhancing crop stress resistance, and preparation and use methods thereof

Abstract

The invention relates to a soil conditioner for enhancing crop stress resistance, and preparation and use methods thereof, and belongs to the field of an agricultural soil conditioner. The soil conditioner for enhancing crop stress resistance is prepared from the following ingredients: 3.0 to 7.0 percent of fulvic acid, 0.20 to 1.0 percent of polyacrylamide, 0.2 to 1.0 percent of polyvinyl alcohol, 1.0 to 5.0 percent of manganese sulfate, 0.001 to 0.01 percent of proline, 1.0 to 5.0 percent of calcium lignosulphonate, 0.02 to 0.05 percent of boracic acid and the balance of water. The inventionalso discloses the preparation method and the use method of the soil conditioner. The soil conditioner for enhancing crop stress resistance, and the preparation and use methods have the advantages that the ingredients of the soil conditioner are simple; the cost is low; the price is cheap; the effects of maintaining the soil moisture, improving the soil agglomeration structure and enhancing the plant resistance can be achieved; meanwhile, the crop growth and development character can be improved; the crop yield is increased; the crop quality is improved; the crop benefits are high; high practicability is realized; the soil conditioner is suitable for being used under the drip irrigation condition; great popularization prospects are realized in the drought region. The preparation method and the use method are simple.

Description

technical field [0001] The invention belongs to the field of agricultural soil conditioners, and in particular relates to a soil conditioner for enhancing the stress resistance of crops and a preparation and use method thereof. Background technique [0002] Soil degradation is a worldwide environmental problem, which has seriously threatened the sustainable development of agriculture. my country is one of the countries with serious soil degradation. Among them, the total area of ​​saline-alkali soil is about 100 million hectares. Saline-alkali soil leads to a decrease in soil fertility, a decrease in nutrient utilization, and poor structural air permeability. The decline in disease resistance seriously affects the yield and quality of crops. my country is also one of the countries most severely affected by drought. The area of ​​desertified soil in my country reaches 126 million hectares, mainly distributed in the arid and semi-arid areas of northern China, and the expans...

Problems solved by technology

Although the soil improver invented by him is rich in nutrition, improves the stress resistance of celery, and promotes crop growth, it is a powder that cannot be applied with water under drip irrigation conditions, and has a narrow scope of application, cannot improve soil structure, and does not have the ability to repair degraded soil. The function is mainly to enhance the nutritional function of the soil. The effect of application in saline-alkali land is not obvious, and the process is mainly for physical mixing, with limited functions. It is only suitable for improving soil nutrient deficiency in facility greenhouses
