Problems solved by technology

The existing saline-alkali land improvement fertilizers have complex production processes, unstable product quality, cumbersome use process, and uneven improvement effects. In particular, the existing formulas have not responded to the problem of saline-alkali land anti-salt, resulting in their improvement effects. The process is getting worse and worse, and every three to five years must be re-invested in improvement, the cost is high

Abstract

The invention discloses a straw half-composed saline land improvement fertilizer which comprises the following raw materials in percentage by weight: 40-50% of half-composed straws, 5-10% of humic acid, 9.8-14.5% of ardealite, 0.2-0.5% of a microorganism improved bacterial agent and 30-40% of farmyard manure. The straw half-composed saline land improvement fertilizer disclosed by the invention takes half-composed straws as a main material, other saline land improvement materials are added, and due to a physical structure formed by the half-composed straw, salt return of soil of saline lands is effectively prevented, and the improvement lasting effect of the improvement fertilizer is prolonged; the crop straw is wide in resource, low in price and low in use cost, and a reuse way for crop straw wastes generated in agricultural production is provided.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers for saline-alkali soils, in particular to an improved fertilizer for semi-decomposed straw saline-alkali soils. Background technique [0002] Saline-alkali soil is a general term for saline soil with too much soluble salt in the soil and alkaline soil with more substitutable sodium. It is a soil type widely distributed on the earth, and it is also an important land resource. At present, the global saline-alkali soil is about 1 million hm per year 2 ~1.5 million hm 2 speed growth. Saline-alkali soil exhibits the characteristics of swelling, dispersion, and muddy when wet, shrinkage, hardening, and hardness when dry, and very poor air and water permeability, which can cause physiological drought of crops, affect the normal nutrition of crops, and even poison them, thereby affecting grain production and leading to a decline in the area of ​​cultivated land. reduce. [0003] China has...
