Insufficient water content in soil affects the plant
The water content in different periods and different parts of the plant body is not the same. The water content of the root tips, young shoots, and green leaves of the seedlings is relatively high, generally 60% to 90%, while the water content in the dry parts is only 40% to 50%. . The lack of water content in plants is likely to cause plant death. The main source of water content in plants is to absorb the water in the soil. Therefore, appropriate moisture should be added when the water content is insufficient. However, excess water is also unfavorable and will be even worse. It is not possible to breathe normally. Therefore, in order to understand and analyze the moisture content of the soil, it is necessary to use a quick soil moisture analyzer, a time-fixed soil moisture detector, and a soil moisture temperature meter to measure the amount of moisture that is added. But one thing to keep in mind when judging drought is to consider the nature of the soil.
When there is insufficient moisture in the soil, the evaporation effect is too strong: it is impossible to properly transport the necessary elements of the crop to the places where the plants need, such as young fruit and seedlings, and the plants cannot grow normally. At the same time, the lack of water also affects the normal progress of the plant's organic matter, photosynthesis. Water deficit will decrease the photosynthetic rate. In the case of slight water deficit, photosynthetic ability can be restored after water supply. If the water deficit is severe, the water potential of the leaf after restoration can be restored to the original level, but the photosynthetic rate is difficult to recover to its original level. The following figure shows the soil moisture. Defects and the process of restoration of water, photosynthesis of plants and other physiological reactions:
Precision Plastic Injection Parts
Plastic injection parts can be seen everywhere in industry and in daily life, and can be said to be the most used parts by humans. All industries such as automobiles, airplanes, ships, electrical and electronic, etc. will use more or less precision plastic injection molding parts, and even our daily washbasins, tooth cups, plastic chairs, power sockets, etc. are plastic injection molding parts. Its biggest feature is that it is widely used, high efficiency, low cost, and high product precision. However, since precision molds are required to form products before production, mold costs and mold opening time need to be invested in the early stage, which is not suitable for small batches of products. Moreover, the development of precision molds is very critical. Only by producing high-precision and durable molds can the accuracy and production efficiency of subsequent products be guaranteed. Therefore, the development of plastic molds is very important for the production of plastic injection parts.
