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...
