In recent years, the state has vigorously advocated the application of organic fertilizers in agricultural production. However, a few people still disagree with this, and fertilizing according to traditional concepts not only pollutes the soil, but also affects crop quality and yield. The application of organic fertilizer has the following five benefits.
1. The source of soil nutrients. Organic matter contains various nutrients needed for crop growth, providing nitrogen, phosphorus, potassium and various trace elements for crop growth. In addition, the carbon dioxide produced by the decomposition of soil organic matter can provide conditions for photosynthesis of green plants.
2. Promote crop growth and development. Humic acid in organic matter can enhance plant respiration, increase the permeability of cell membranes, and enhance the absorption of nutrients, while vitamins and some hormones in organic matter can promote plant growth and development.
3. Improve soil structure. The humus in organic matter helps the cohesive soil to form a good structure, change the soil pore condition and the ratio of water and air, and create a suitable soil tightness.
4. Improve soil fertility retention capacity. The organic colloid in the soil organic matter can absorb a large amount of cations and water, and its cation exchange capacity and water absorption rate are several times or even tens of times larger than that of clay particles, so it can improve the ability of the soil to retain water and retain moisture. Improve the buffering of soil to acid and alkali.
5. Increase soil nutrients. Humus in organic matter has a complexing effect, which helps eliminate soil pollution. For low-yield fields, increasing the organic matter content can fertilize the soil and increase the fertility level. For high-yield fields, as organic matter continues to decompose, organic matter needs to be continually replenished. Humus can form complexes or chelates with phosphorus, iron and aluminum ions to avoid the precipitation of insoluble phosphate and increase the amount of effective nutrients. It is necessary to change the concept of fertilization, increase the application of organic fertilizers, and increase the content of soil organic matter in order to give full play to the role of chemical fertilizers in increasing production.

When the elderly get older, their body functions and physical strength will decline. Sometimes it is difficult to bend down and bend back. It is a very difficult process from lying down to getting up. Today, we introduce a kind of auxiliary equipment for health care - bedside handrail.
