Problems solved by technology

[0004] Alfalfa is a high-quality perennial leguminous plant with good palatability and high-quality grass. It is a high-quality pasture grass; it also has a certain ability of salt-alkali tolerance and can be planted in mildly saline-alkali land, but its growth and yield are not good.
Xinjiang has a vast area of ​​saline-alkali land, of which sandy saline-alkali land is the main area in southern Xinjiang. The predecessors have done a lot of research on soil conditioners in saline-alkali land in Xinjiang. Humic acid, zeolite, desulfurized gypsum and other soil conditioner products are beneficial to the cultivation of alfalfa in saline-alkali land. Research has been conducted, and in terms of the effect of using a single product, desulfurized gypsum has the best performance in increasing the emergence rate and yield of alfalfa planted in that year, but the alfalfa yield in the coming year has not been effectively guaranteed
At present, there is no special soil conditioner product for alfalfa planting in saline-alkali land. It is urgent to develop a special soil conditioner for alfalfa planting in saline-alkali land, and support the application method in saline-alkali land, so as to effectively improve the survival rate and yield of alfalfa in saline-alkali land.

Abstract

The invention discloses a soil directional conditioning agent and a preparation method thereof, and a method for planting alfalfa by using the conditioning agent, which belong to the technical field of agriculture plantation. The soil directional conditioning agent suitable for saline-alkali land to plant the alfalfa is composed of, by weight, the following components: 25-30% of desulfurized gypsum powder, 20-25% of weathered coal, 20-25% of decomposed cow dung, 10-15% of nitragin, 10-15% of rice straw powder, and 5-10% of calcium sulfate The soil directional conditioning agent of the invention takes growth characteristics of the alfalfa and the characteristics of the saline-alkali land into consideration, composition of the components is simple, the components interact with each other, the seedling emergence rate of the alfalfa in the saline-alkali land is improved, and the seedling emergence time is shortened; and the output of the alfalfa in the same year can be improved, and the output of the alfalfa in the coming year is also ensured.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a soil directional conditioner, a preparation method thereof and a method for planting alfalfa using the soil conditioner. Background technique [0002] Saline-alkali soil is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to the soil containing carbonate or heavy phosphate, the pH value is high, the soil is alkaline, the organic matter content of saline-alkali soil is small, the soil fertility is low, the physical and chemical properties are poor, and there are many anions and cations harmful to crops. Promote seedlings. [0003] The area of ​​saline-alkali land is vast in the world. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world ...
