1 Check the seedlings to make up for shortages and timely seedlings. Usually 10-15 days after sowing, the seedlings are fully investigated after the basic seedlings. If there is a shortage of seedlings, it is necessary to promptly regenerate the seedlings, or to select a cloudy or sunny afternoon to transplant the seedlings to fill the deficiency. If the temperature is high at the seedling stage, the seedlings (mainly referred to as mulching peanuts) must be promptly processed.
2 Scientific weeding. Before the emergence of peanuts, timely close the ground with herbicides, peanuts Qi Qimiao, try not to spray, so as not to damage the young leaves of peanuts, affecting growth.
3 Moderate cultivator. Generally, three or four times of cultivators are needed, and the common people have the idea of ​​“scraping (shallow rakes), digging (deep borings), three paths, four paths, such as rusty flowers (fine rakes)â€. About two inches deep.
4 Prevent leaf spot disease in advance. Peanut leaf spot disease has already occurred after the peanuts have been established. In particular, early peanuts are sown. Therefore, early prevention and control must be carried out. After the peanuts are seedlings, use pure carbendazim 800 times or thiophanate-methyl 800 times, spray once every 7 days, spray at least 2 times. At the same time, imidacloprid and nutrients can be added to achieve the effect of “one spray and three preventions†for disease prevention, pest control and nutrition.
5 appropriate amount of timely fertilizer. Fertilizers at the seedling stage should be carried out before flowering to promote seedlings and flower bud differentiation. The number depends on the seedling condition. If the leaves are fine and pale, it is recommended to apply 4-5 true leaves to one fertilizer, 4 mus of urea to 4 kg, or to dilute urine to 20 lbs; if the leaves are large and the leaf color is dark, it is not necessary. Application or discretionary application of less, focusing on phosphorus, potassium, to prevent excessive growth, premature closure.
