Description

Organic silicon soil conditioner and preparation method thereof

Technical Field

The invention relates to the technical field of land improvement, in particular to an organic silicon soil conditioner and a preparation method thereof.

Background

The soil conditioner is a product which is prepared by using agricultural water-retaining agent and natural peat or other organic matters rich in organic matters and humic acid as main raw materials, and biological active ingredients and nutrient elements as auxiliary materials and processing the raw materials by a scientific process. The soil conditioner has three remarkable conditioning performances of water retention, fertility enhancement and air permeability.

The existing soil conditioner is mostly used by a base fertilizer method with soil plowing or ditching and backfilling. If the fertilizer is scattered on the soil surface by a top dressing method, the following defects exist: 1. raise dust is easy to generate and is unfavorable for the leaf surfaces of crops and operators; 2. the spreading is not uniform, and the cement-like hardening phenomenon is easy to cause by moisture, so that the effect is influenced. Although watering immediately after fertilization can solve the problems of foliage and dampness of crops, the labor is increased. In addition, the existing soil conditioner is too much lost under the impact of rainwater or watering, and the continuous effect of the existing soil conditioner cannot be reflected. Importantly, the existing silicate soil conditioner is formed by high-temperature calcination and grinding, contains almost no moisture, and has the defects in various aspects. In addition, the silicate soil conditioner with the water content of almost zero is easy to fly dust, and is difficult to exhaust during charging; after the material is charged, the material bag is not stable in shaking, the material bag needs to be manually supported on a belt to be conveyed for sealing, and although the problem can be relieved by changing individual packaging equipment, the packaging progress is difficult to improve. Materials containing certain moisture are easy to exhaust due to the fact that the materials have large gravity, the materials can be packaged according to a normal fertilizer packaging method, production progress is promoted, and the existing silicate soil conditioner is easy to harden due to hydration reaction after water is added.
