Soil conditioner and preparation and application methods thereof

Abstract

The invention relates to a soil conditioner and preparation and application methods thereof. The soil conditioner is prepared from the following ingredients in percentage by weight: 30% to 35% of overrotten organic fertilizer, 35% to 40% of fruit tree branch charcoal, 14.5% to 19.5% of oyster shell powder, 8% of pyroligneous liquor, 6.0% of natural humus acid, and 1.5% of titanium oxide. The conditioner has effects of loosening soil, improving soil acidification and removing soil hardening, and has effects of improving water and nutrient retention capacity of soil, supplementing trace elements in soil calcium and magnesium and reducing crop diseases and pests. The soil conditioner can replace slaked lime, an organic fertilizer and the like as the soil conditioner to be applied to the planting industry.

Description

technical field

[0001] The invention relates to the field of organic fertilizers used for planting, in particular to a high-efficiency, environment-friendly soil conditioner and a preparation and application method thereof. Background technique

[0002] For a long time, people have been pursuing the high yield of crops. In order to achieve this goal, they often overuse agricultural inputs such as chemical fertilizers and pesticides. Disease aggravation, etc. In actual production, in order to solve the acidification, salinization, and compaction of soil, some directly use slaked lime. However, the ability of slaked lime to adjust acid is too strong, which has caused damages such as crop root burn and new soil compaction.

[0003] In addition, some of the existing technologies use organic fertilizers, which have a certain effect on eliminating hardening, but have relatively poor effects on increasing the pH value and reducing the salt content. For example, the Chinese invent...
