Problems solved by technology

In addition, if the soil is too alkaline, it will affect the availability of nutrients such as phosphorus, iron, manganese, boron, and zinc in the soil, and will easily cause a large amount of nitrogen, phosphorus, and potassium major elements, as well as trace elements such as iron, calcium, and boron.

Abstract

The invention discloses an ameliorant combination suitable for secondary saline-alkaline soil in irrigation areas of the Yellow River. The ameliorant combination comprises, by weight, 120-180 parts of a soil loosening agent, 250-400 parts of citric acid residue, 160-200 parts of diatomite of 1,250-2,000 meshes, 120-160 parts of ammonium molybdate, 80-120 parts of sodium selenite, 30-60 parts of seaweed slag, 8-20 parts of straw ash, 800-1,200 parts of coconut residuum and 10-14 parts of microbes. The soil loosening agent is a mixture obtained by crushing peat, dry pine needle, vermiculite, natural zeolite and peanut shell according to the mass ratio of 5:3:1:2:1. According to the ameliorant combination suitable for secondary saline-alkaline soil in irrigation areas of the Yellow River, various nutritional ingredients are reasonably cooperated, and various components are combined mutually, influence each other and coordinate with each other. Then, soil secondary saline-alkalization caused by random fertilization can be avoided.

Description

technical field [0001] The invention relates to a soil improver, in particular to a combination of improvers suitable for secondary saline-alkali soil improvement in Yellow River irrigation areas. Background technique [0002] Saline-alkali soil is a general term for saline soil, alkaline soil and various salinized and alkalized soils. Saline soil refers to the soil in which the soluble salt content in the soil reaches a certain level, which can cause obvious harm to the growth and development of plants. Alkaline soil refers to the soil that contains a large amount of exchangeable ions in the soil, and the amount reaches the level that can harm the growth and development of plants and change the soil properties. In actual conditions, saline soil and alkaline soil often coexist in a mixed manner, collectively referred to as saline-alkali soil. [0003] Soil secondary salinization, also known as "secondary salinization", refers to the process of turning good cultivated land ...
