The correct management plan for spring vegetable seedlings

The correct management plan for spring vegetables and seedlings The seedlings of vegetables should pay attention to the temperature, humidity and light intensity in the environment after transplanting. After the rural vegetable seedlings are transplanted, they will adopt some methods to increase their survival rate. The most common method is to fold some branches. To be inserted next to the seedlings and watered properly after planting, measurements were made using a temperature-humidity monitor and a photon quantizer. Both measures were appropriately reduced in light intensity and temperature, while the humidity was increased.
After the transplanting of seedlings, there are certain requirements for the temperature and humidity in the environment. The temperature is closely related to the growth of seedlings. Within a certain temperature range, with the increase of temperature, the photosynthesis of seedlings is enhanced, but beyond a certain range. When the temperature is raised again, photosynthesis will not increase again. Instead, the increase in respiration will weaken the accumulation of nutrients in the seedlings. When the temperature is too low, all physiological activities are inhibited, and severe freezing damage occurs.
Most of the water needed for seedling growth is absorbed from the soil, but the amount of air humidity determines the amount of absorption and the rate of absorption. The relative humidity of the indoor air in the general seedling shed should be controlled at about 70%. When the humidity is too high, the transpiration of the plants is hindered, which affects the rate of absorption. Excessive air humidity also easily leads to the occurrence of diseases and insect pests. Humidity is too small, transpiration is increased, and the seedlings are easily withered.
Illumination in the customization process of plants has a relatively large impact. After the planting, the seedlings must be finer to have a certain fusion period with the soil. Only after this fusion period, as the light intensity increases, the photosynthesis of plants will increase. Therefore, in the customized days, the light intensity in the environment should be controlled. In this monitoring, the light quantum recorder can be used to perform fast and accurate measurements. After the colonization period, the light intensity is increased to promote the synthesis of organic substances. .
