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] Traditionally, chemical fertilizers are used to increase the yield in rice cultivation, but a single chemical fertilizer will deteriorate the soil environment, resulting in the phenomenon that the increase in application does not increase the yield, and the quality of rice continues to decline. Rice is a silicon-loving crop, and continuous cropping makes the soil The continuous decrease of available silicon leads to the reduction of rice yield

preparation example Construction

[0045] A preparation method for a soil conditioner for paddy rice, comprising the following steps:

[0046]1) Classification: the clinker is divided into two parts, which are respectively recorded as the first clinker and the second clinker; wherein, the particle size of the first clinker is greater than 100 mesh, and the particle size of the second clinker is less than 100 mesh. More than 100 mesh;

[0047] 2) Ball milling: placing the first clinker in a ball mill, and ball milling until the particle size is not greater than 100 mesh;

[0048] 3) Mixing: mix the ball-milled first clinker with the second clinker, and stir until uniform, to obtain the soil conditioner for rice.

[0049] As a preferred solution, the soil conditioner for rice is prepared according to the following steps:

[0050] 1) Ball milling: place the silicate soil conditioner clinker containing citrate-soluble silicon calcium magnesium and molybdenum in a ball mill, and ball mill to about 100 mesh;

Abstract

The present invention discloses a soil conditioner for rice and a preparation method and an application method thereof. The soil conditioner is prepared from clinker containing calcium element, magnesium element, silicon element and molybdenum element and a trace element fertilizer. The trace element in the trace element fertilizer is zinc element, or the trace element in the trace element fertilizer is a combination of zinc element and molybdenum element. The effective nutrient components in the soil conditioner comprise 18-22% of calcium, 11-13% of magnesium, 11-13% of silicon, 0.1-0.5% of zinc and 0-0.003% of molybdenum. The soil conditioner can improve the yield and quality of the rice, improve the lodging resistance of the rice and enhance the pH value of the soil.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil conditioner for rice and its preparation method and application method. 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, degra...
