How to use soil conditioner rationally

A: It refers to the material added to the soil to improve the physical and/or chemical properties of the soil and/or its biological activity. According to different functions, it can be divided into: soil agglomerates and soil particles, and soil cement to improve soil structure; soil stabilizers to fix topsoil and prevent water and soil loss; soil acidifying agents to adjust soil pH; and soil warming to increase soil temperature. Agents; Soil water retention agents that can maintain soil moisture.
China has large-scale traits of low-yielding fields and adverse soil. In recent years, due to the improper use of chemical fertilizers, the input of organic fertilizers has decreased, and many farmland characters have deteriorated, and the soil fertility has shown a downward trend. In this case, in addition to improving soil fertility through rational fertilization and cultivation, the scientific use of soil conditioners is also an effective measure. It can improve the soil and increase soil fertility. Although it does not provide nutrients directly to the crop, it provides favorable conditions for improving plant nutrition.
The selection of conditioners mainly depends on the soil amendment objectives, soil improvement effects, and material characteristics of the conditioners. Specifically consider the following aspects:
Conditioning agent material characteristics. If it is a natural resource conditioner, the application amount can be larger, and the range of suitable dosage is wider; and the artificially synthesized conditioner has a much smaller amount due to higher efficiency and cost. For example, weathered coal is added with an appropriate amount of ammonia water or mixed with ammonium bicarbonate for fertilization and soil improvement. The application rate per acre is 30 to 100 kg. It can be applied after plowing to dig soil or furrows and acreage; polyacrylamide is used to increase soil. Aggregate structure is the main purpose, the appropriate amount is generally 1.33 ~ 13.3kg, can be sprayed on the surface of the liquid or dry sprinkled in the topsoil, mixing with a disc harrow. It should be noted that the use of less conditioner will not work, and not only will the cost increase, but it may also have the opposite effect.
Conditioning agent application conditions. Soil conditions have a great influence on the application effects of conditioners. Soil moisture affects uniformity of conditioner dispersion, soil moisture is too high, ploughability is poor, field operations are difficult, and it is difficult to mix evenly; Soil texture affects the agglomeration of soil particles with sand, and the effect of clay reunion is better than that of sand. The high content of organic matter has a relatively low effect. The purchase or application of soil conditioners must not only consider the need to improve the soil, but also take into account economic conditions and capabilities. First, we must make full use of inexpensive natural resources such as peat/straw and lime, gypsum and other minerals. However, the use of organic materials and natural minerals is relatively large. It should be developed nearby and applied nearby.
How to face new products. In recent years, there have been new soil conditioner products coming out. Before buying, it is necessary to carefully understand the true and false features of the products, and carefully follow the requirements of the specification when applying.

Nuts can generally be divided into two types: one is seeds, such as sunflower seeds, pumpkin seeds, peanuts, etc.; the other is tree nuts, such as pistachios, hazelnuts, cashews, walnuts, pine nuts, walnuts, chestnuts, almonds. And the macadamia and pecans that have been very hot in the past two years. These nut foods contain more protein, calcium and a variety of vitamins, which can provide the body with a variety of nutrients needed by the brain and body.

In general, a nut is a closed fruit classification of a nutrient-covered woody or leathery hard shell. The skin is hard and contains one or more seeds. It includes two types of tree nuts and fruit seeds, walnuts, chestnuts, pistachios, almonds, etc., which belong to the fruit seed class.
