Key points of Peanut Seedling Management

Under normal circumstances, after peanut seeds are sown, seedlings will grow in half a month, and if the seedlings are managed properly, they will not be far away from high yield. what are the key points of peanut seedling management?

1. And time to replenish seedlings

Peanuts in the 10-15 days after sowing, to check the growth of the whole garden, and time seedlings to supplement seedlings, generally lack of seedlings should be timely transplanting the place where the growth is dense. Or sprout and replant in time. When transplanting, it is appropriate to water the seed or transplant with soil. Replanting should be early to prevent the emergence of young seedlings and affect the density. If the temperature is high in the seedling stage, it is necessary to pick up the seedlings in time (mainly refers to plastic film peanuts), otherwise it is easy to cause the phenomenon of roasted seedlings, thus affecting the normal growth of peanuts. Seedling replenishment is usually carried out before 8 o'clock in the morning and after 5 o'clock in the evening. It should be carried out 2 or 3 times before the first flower.

2. Timely ploughing and weeding

After peanuts grow and grow, check the situation in the ditch. If you find weeds, close the ground with herbicides in time. After peanuts are full of seedlings, try not to spray them, so as not to harm the tender leaves of peanuts and affect their growth.

3. Moderate ploughing

After emergence, peanuts should be ploughed three or four times, namely, first scraping (shallow hoe), second digging (deep hoe), three and four hoes, of which the shallow hoe does not exceed 1cm and the deep hoe does not exceed 2cm.

4. Prevention of leaf spot in advance

From the production practice of peanuts, peanut leaf spot has already occurred after peanut seedlings are complete, especially for early sowing peanuts, due to long emergence time, obviously low air and ground temperature, hindered root growth, insufficient nutrient absorption, and slow plant growth. It is extremely vulnerable to the invasion of bacteria, so it must be prevented and controlled in advance. After peanut seedlings, spray with 800 times of pure carbendazim or 800 times of thiophanate methyl, every 7 days, at least twice. At the same time, imidacloprid and nutrition can be added to achieve the effect of disease prevention, insect control, nutrition spray and three prevention.

5. Timely and appropriate amount of topdressing

Topdressing at seedling stage should be carried out before the beginning of flowering to promote seedling emergence and flower bud differentiation. The quantity depends on the seedling condition, if the leaves are thin and light, it is appropriate to apply fertilizer once in 4 to 5 true leaves, 4 kg urea per mu, or 20 piculs of dilute manure and urine; if the leaves are wide and dark, they can not apply or apply less as appropriate, focusing on phosphorus and potash fertilizers to prevent excessive growth and premature closure.
