What should be paid attention to in peanut seedling stage?

What should be paid attention to in peanut seedling stage? Also ask experienced netizens to help introduce the period when peanut seedlings are unearthed, show two true leaves to the emergence of flowers, and the main stem has 7-8 true leaves in the seedling stage. The planting network has sorted out the matters that should be paid attention to in the peanut seedling stage, which are listed below for netizens' reference. 1. The temperature of peanut seedling stage: the temperature of 20-22 ℃ is the most suitable for the development of stem and branch and leaf growth in peanut seedling stage. When the average temperature is more than 25 ℃, the seedling stage can be shortened, the stems and branches will grow, and the basal nodes will be elongated, which is not good for squatting seedlings. When the average temperature is lower than 19 ℃, the differentiation of stem and branch is slow, the differentiation of flower bud is slow, the initial florescence is delayed, and the "young and old seedling" is formed. Second, peanut seedling water: peanut seedling plant water demand is the least, accounting for about 3.4% of the total. At this time, the most suitable soil water content is 45% 55% of the maximum field capacity, less than 35% of the maximum capacity, new leaves are not shown, flower bud differentiation is inhibited, and the initial flowering period is delayed; higher than 65% of the maximum water capacity, it is easy to cause stem and branch elongation, basal node elongation, slow root development and shallow prickling, which is not conducive to the formation of flower organs. Third, the light of peanut seedling stage: the optimum sunshine hours per day is 8-10 hours in peanut seedling stage. When the sunshine hours were more than 10 hours, the stem and branches grew only, and the flowering stage was delayed; less than 6 hours, the stem and branches grew slowly and the flowering stage was advanced. Peanut requires a large range of light intensity, the optimum light intensity is 51000 ridge / m ~ 2, less than 10200 ridge / m ~ 2 or more than 82000 ridge / m ~ 2 affect the photosynthetic efficiency of leaves.
