Abstract

The invention relates to a novel selenium-enriched nutritional liquid preparation method and belongs to the field of chemical fertilizers. The nutritional liquid comprises a component A and a component B, wherein the component A is composed of sodium selenite, zinc sulfate heptahydrate, sodium perborate tetrahydrate, EDTA disodium and ferrous sulfate while the component B is composed of an EM bacterial raw liquid, monopotassium phosphate, magnesium sulfate and sodium selenite; when the nutritional liquid is used, the components A and B are mixed in water and sprayed on foliage of a plant, so that the content of heavy metals in soil and plant can be reduced, the metal trace elements of the nutritional liquid are prevented from being fixed by soil, the utilization ratio is improved, the soil pollution is reduced, and moreover, crops can be promoted to grow, plant diseases and insect pests are prevented, and the plant quality and output are improved.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a method for preparing a novel selenium-enriched nutrient solution. Background technique [0002] my country is a big agricultural country with a dense population. In order to meet people's living needs, the use of chemical fertilizers in grain planting is essential. However, due to the low utilization rate of chemical fertilizers in my country, the soil fertility is reduced, and the degree of soil compaction is becoming more and more serious. At the same time, due to the rapid development of modern technology, various heavy metals are left in the soil, causing the heavy metals in the soil to exceed the standard. cycle. [0003] In order to improve the utilization rate of chemical fertilizers and reduce the amount of chemical fertilizers, chemical fertilizer synergists came into being. Selenium is a beneficial element required for plant growth. Selenium can stimulate the grow...
