Peanut cotyledons should not be unearthed or semi-excavated. When the first cultivating is carried out after the peanut seedlings, the soil around the seedlings is opened with a small hoe to form a "small nest", so that the two cotyledons and the first pair of side branches Exposed to the soil surface, directly exposed to the sun, in order to facilitate the first pair of side branches to develop vigorously, so that the seedlings grow robust and achieve high yield. Qingcao can promote the strong growth of stem-based branches and the early branching of secondary branches, and play a role in seedlings. Clearing the tree can also increase the effective flowers and concentrate. The time of clearing the tree should not be too early, so as to prevent the yellow bud seedlings from being too weak, the leaves are easy to be sunburned, and the topsoil is too dry, which affects the development of young roots. Clearing the tree should not be too late, because the first pair of side branches are buried for too long, affecting early fast-growing, losing the role of clearing the tree, the best period of clearing the tree is the basic seedling period. The depth of the clearing tree is suitable for the exfoliation of the cotyledonary leaves. The shallow Zhangziyin leaf section cannot completely expose the soil surface. The first side branch and the stem base are still buried in the soil, which can not be used for clearing the tree; The following embryos stem out, which is easy to cause seedlings. It is advisable to maintain the seedlings for 15-20 days, that is, the roots of the stems and branches are changed from purple to green, and when the secondary branches begin to divide, the seedlings are finished and the second cultivating is carried out.
The micro peristaltic pump is suitable for many general fields such as laboratories, pharmaceutical industry, fine chemicals, water treatment, environmental protection engineering, food and beverage production dosage additives, acid supplementation and alkali defoaming in technological fermentation systems, scientific experiments, etc. The mini peristaltic pump is pollution-free, the liquid only touches the pump tube, the transmission accuracy is high, and it is easy to clean. It can work again only by replacing the pump tube.
