Problems solved by technology

[0006] For the deficiencies in the prior art, the object of the present invention is to solve the problem of soil salinization and hardening caused by fertilizer hardening and excessive fertilization by adding anti-hardening agent and humic acid powder in the drip irrigation fertilizer. The reasonable combination of elements and trace elements can effectively improve the physical and chemical properties of the soil while meeting the needs of crop growth, avoiding the accumulation of salt again, and can prevent crops from nutrient deficiency symptoms. At the same time, the preparation method has a simple process and is easy to operate. Etc

Abstract

The invention discloses an anti-hardening drip irrigation fertilizer suitable for improving salinized and hardened soil and a preparation method thereof. The anti-hardening drip irrigation fertilizeris prepared from the following raw materials in parts by weight: 10 to 20 parts of nitrogen fertilizer, 15 to 25 parts of phosphate fertilizer, 15 to 25 parts of potash fertilizer, 10 to 20 parts of humic acid powder, 0.5 to 2 parts of trace elements and 5 to 10 parts of an anti-hardening agent, and all the raw materials are crushed and mixed to obtain the anti-hardening drip irrigation fertilizer. The product is suitable for salinized and hardened soil, the anti-hardening agent in the product enters a salinized layer of soil after fertilization, the binding force between salting-out crystalsis destroyed, the soil structure is adjusted, nutrient elements needed by growth and development are provided for crops, and therefore the dual effects of improving soil and providing nutrition are achieved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a compaction-resistant drip irrigation fertilizer suitable for improving salinized compacted soil and a preparation method thereof. Background technique [0002] Soil salinization compaction refers to the lack of organic matter in the soil plow layer due to the long-term application of high-concentration inorganic fertilizers. Hardening is a phenomenon, and usually this type of hardening will be accompanied by "hoarfrost". There are many factors that cause soil salinization and compaction. Usually, excessive application of chemical fertilizers leads to low soil organic matter content, poor structure, and nutrient imbalance in the soil, which destroys the soil aggregate structure and affects the activity of microorganisms. The harm of soil compaction is huge. (1) Plant root respiration is blocked. In the case of soil compaction or long-term flooding, plant root ce...
