Cultivation method of peanut
1, seed treatment
Potted plants need fewer seeds, so you can choose 1 ~ 4 healthy seeds, then soak them in water for 1 night, and you can sow the next day. Sowing with 1 ~ 2 cm soil is enough. It is suggested that film should be attached after sowing, which is helpful for early germination. It can germinate directly under light in about 1 ~ 7 days.
2. Emergency management
The germination stage is when 50% of the seedlings are unearthed and the first real leaves are unfolded. At this time, the growth characteristics of peanuts are mainly vegetative growth such as rooting, branching and long leaves. After the seeds germinate and emerge, check the seedlings immediately, find the missing seedlings, replant or replant them in time according to the lack of seedlings, and pay attention to the prevention and control of pests and diseases.
3. Seedling management
Peanut seedling stage is generally 20 ~ 35 days. The growth characteristics of this period are mainly vegetative growth, and flower buds begin to differentiate to form nodules. Adequate water and fertilizer, especially nitrogen fertilizer, should be ensured at seedling stage to promote nodule formation and flower bud differentiation.
But don't apply too much fertilizer, lest the branches and leaves grow too fast and the results are not enough. At the same time, we should do a good job in weeding to prevent root rot and other diseases. Cultivate strong seedlings, promote the early growth and rapid development of the first and second pairs of lateral branches, and strive for more effective flower buds.
