Background
China is a big population country, the cultivated land resources are relatively in short supply, and the area of the saline-alkali soil accounts for more than 10% in the limited cultivated land resources. The saline-alkali soil has high pH value and salt content, influences the normal growth of crops and causes low crop yield. Therefore, the reasonable method for treating the saline-alkali soil is related to the sustainable development of agriculture and the food safety in China. A plurality of saline-alkali soil conditioners are developed in the market at present, wherein the microbial saline-alkali soil conditioner has low investment, can improve the micro-ecological environment of soil by utilizing the existing nutrient elements in the soil, and has wide market value and application prospect. However, because of the high technical content of the microbial fertilizer and the high production difficulty, the high-quality products in the market of China are few. The current production capacity of the microbial fertilizer in China is far from meeting the market demand.
According to the requirement of the industrial standard of the compound microbial fertilizer of Ministry of agriculture, the number of effective viable bacteria is the main technical index of the product, and the number of the effective viable bacteria must be more than 2 million/g. However, in order to ensure high viable bacteria amount, the carrier raw material accounting for 70-80% of the formula proportion of the product is the main factor influencing the viable bacteria amount. The composite microbial fertilizer products produced in the current market are powdery and granular, and the powdery products are not suitable for machine sowing and directly influence the use and popularization of the products; granular products can be produced by means of disc granulation, roller granulation or double-roller extrusion granulation, and mainly have the following technical problems:
1. disc granulation and roller granulation belong to wet-type production processes, the moisture content of the granulated product is high, the granulated product is usually dried in a high-temperature drying mode, the temperature is about 200 ℃, the duration is more than 15 minutes, and the quantity of viable bacteria is greatly influenced; if normal-temperature drying is adopted, longer time is needed, and the production efficiency is influenced;
2. extrusion granulation belongs to a dry-type production process, granulation is carried out by high-strength extrusion, but the temperature is up to more than 60 ℃ at the moment of high-strength mechanical extrusion, and even if a low-temperature drying method is adopted later, the activity of viable bacteria is still greatly influenced, so that the method is not suitable for preparing the improver containing the bacteria;
3. when the cylinder granulation, the material adheres easily on the cylinder inner wall, is difficult to clear up, if the material adheres to the agglomeration piece on cylinder discharge end inner wall, the material of agglomeration piece can be too big because of the granule during the ejection of compact, and unsatisfied requirement.
