Soil conditioner refers to the material used to improve the physical and chemical properties of soil and its biological activity. It is mainly composed of agricultural water-retaining agent and natural mud rich in organic matter and humic acid, pure natural ore or other organic matter, supplemented by biological activity. The composition of ingredients and nutrient elements, the products processed by scientific technology have extremely significant functions such as “water retention, loosening soil, fattening, and ventilation”. Although soil conditioners cannot replace the use of NPK fertilizers, they can improve soil structure, promote the absorption of nutrients by crops, reduce the use of chemical fertilizers, and finally achieve the effect of increasing crop yields.
As long as the soil conditioner is used reasonably, it can achieve the effect of restoring the healthy body of the soil, but we need to use the most scientific and reasonable combination according to the characteristics of different types of conditioners.
Mineral sources + macromolecular polymers can quickly improve soil structure.The most specific mineral source soil conditioner is silicon calcium magnesium fertilizer, and these three types of elements themselves are the most important components of soil structure. If these elements are lacking, the soil structure will be destroyed, and to improve the soil structure, the silicon, calcium and magnesium in the soil must be supplemented. The representative product of macromolecular polymer soil conditioner is polyacrylic acid, which can quickly aggregate soil molecules and make soil aggregate into agglomerate structure. However, the requirements for the use of such products are very strict, especially not excessive amounts. Excessive amounts will lead to aggravation of soil colloidization, which is counterproductive.
Functional fertilizer + microbial inoculum.The soil in the greenhouse is often mixed with a variety of problems. For example, the soil deteriorates obviously, and the diseases mostly occur at the same time. Sometimes it is difficult to rely on one thing to play an effective role. At this time, functional fertilizers can be reasonably matched according to the actual situation to make them play the role of 1+1>2. Functional substances such as humic acid, alginic acid, and chitin all have the effect of promoting the proliferation of beneficial bacteria. For example, after humic acid improves the soil structure, the permeability is enhanced, and soil microorganisms will naturally increase; alginic acid fertilizer is rich in nutrients and has strong activity, which can also increase the number of beneficial bacteria; in promoting the proliferation of microorganisms, chitin has the most obvious effect. The proliferation rate of actinomycetes increased by 30 times, and the proliferation rate of Bacillus was increased by 6 times, and the effect was extremely prominent.
Organic fertilizer + biological bacterial fertilizer, maintain soil health.After soil improvement, if it is not maintained, it will be destroyed again in a short time, and the healthy organism of soil includes not only the physical structure of the soil, but also the balance of nutrients and ecology. Therefore, after completing the rapid improvement of the soil, it is necessary to rationally use organic fertilizers and biological bacterial fertilizers. Organic matter and biological bacteria are complementary to each other. The decomposition and utilization of organic matter requires biological bacteria, and it is impossible for biological bacteria to survive without organic matter. Therefore, the two need to be used together. By increasing the amount of the two, the content of beneficial bacteria in the soil can be increased, and the problem of soil ecological imbalance can be solved in the long run.
It should be noted that to understand and judge whether the soil has a tendency to deteriorate or has deteriorated, the soil must be tested by a formal testing department to determine whether appropriate soil conditioners should be used for proper conditioning to restore soil function. The main function of soil conditioner is to improve the partial acid, partial alkali, salinization and compaction of soil, so it cannot be used for a long time.
