Abstract

The invention provides a soil conditioner beneficial to vegetable cultivation and a preparation method thereof. The invention relates to the technical field of soil conditioners. The soil conditioneris prepared from the following raw materials in parts by weight: 5-10 parts of calcium nitrate, 3-8 parts of monopotassium phosphate, 5-10 parts of potassium sulfate, 10-20 parts of carbonized rice husk, 10-20 parts of shell powder, 10-20 parts of zeolite powder, 22-35 parts of decomposed municipal sludge and 20-40 parts of potassium-rich slate leavening. The soil conditioner is high in functionality and various in raw materials, contains organic and inorganic components and EM flora, can improve soil nutrients and soil pH, and is beneficial to vegetable cultivation and propagation due to scientific and reasonable compounding of the raw materials.

Description

technical field [0001] The invention relates to the technical field of soil improvers, in particular to a soil improver beneficial to vegetable cultivation and a preparation method thereof. Background technique [0002] Vegetable cultivation in my country has a long history. There are many kinds of vegetables, and the organs of the products are diversified. The growth and development laws have different requirements for environmental conditions. Conditions such as soil, water, and temperature are the basis for the cultivation of various vegetables. In the process of vegetable production, especially the production of greenhouse vegetables, due to the continuous planting of vegetables all year round, the use of pesticides and fertilizers is more, the garden soil acidification, salinization, compaction and other soil obstacles are serious, crop diseases and insect pests are increasing year by year, crop physiological drought, ion exchange Imbalance, poor permeability, weak root...
