Soil conditioner for tuber crops and preparation method thereof

Abstract

The invention discloses a soil conditioner for tuber crops and a preparation method thereof. The soil conditioner is prepared from a clinker containing calcium, magnesium, silicon and potassium and trace elements; the trace element are a combination of boron, zinc and sulfur; and the soil conditioner comprises the following effective nutritional components in percentage by weight: 20-25% of calcium, 12-15% of magnesium, 10-12% of silicon, 2-2.5% of potassium, 0.2-0.25% of boron, 0.25-0.5% of zinc, and 0.5-1% of sulfur. The soil conditioner provided by the present invention mainly contains silicon, magnesium, calcium and potassium, which are matched with other trace elements which can strengthen the intrinsic quality of tubers, and by use of the effects of increasing the yield and improving the quality of the tuber crops, and improving soil of the above elements, the purposes of keeping nutrient balance of the tubers, and improving the yield, quality and storage endurance are achieved.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil conditioner for tuber crops and a preparation method thereof. Background technique [0002] Soil conditioners originated in the 1950s. Early research mainly used small molecule organic materials, mainly soil structure stabilizers. Following the further research on soil conditioners, some countries such as Belgium and the United States began to study soil water retaining agents in the 1980s; in the 1990s, Britain, France, Japan, Belgium, etc. studied soil water and fertilizer conditioners. In the 21st century, from the perspective of food intrinsic quality and food safety, various countries began to study the supplementation of medium and trace elements and repair of polluted soil conditioners. [0003] At present, due to the irrational use of chemical fertilizers in our country, the increasingly prominent problems of soil pollution, acidification, degradation, an...

Problems solved by technology

Lack of pertinence, resulting in waste of resources, may not really solve the problem of reduced food production and lower internal quality

[0004] In order to pursue the yield of potato crops, a large amount of chemical fertilizers are used to achieve the purpose of increasing production, but the use of chemical fertilizers for a long time will deteriorate the soil environment, the yield will increase, but the starch content will continue to decline, and there will be deformed products, which are easy to rot and cannot be stored.
