1. Check the seedlings for deficiency and timely seedlings and 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. Supplementary time should be watering species or transplanting with soil. Replanting early to prevent the emergence of young seedlings, affecting the density. If the temperature is high at the seedling stage, the seedlings (mainly referred to as mulching peanuts) must be promptly prepared. Otherwise, the phenomenon of roasted seedlings will easily occur, which will affect the normal growth of peanuts. Seedling emergence seedlings generally before 8 o'clock in the morning, after 5 o'clock in the evening, the first hole to open the air, until the peanut seedlings after the appropriate seedlings, since the beginning of the regimental period, we must promptly check and absorb the pressure buried under the membrane The lateral branches make it robust. It takes 2-3 times before starting flowering.
2. Scientific weeding. In order to prevent the grass from growing in the peanut ditch, the ground should be closed with herbicide immediately before the emergence of the peanuts. After the peanuts are seeded, they should not be sprayed so as not to harm the young leaves of the peanuts and affect their 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. From the perspective of peanut production practice, peanut leaf spot disease has already occurred after peanuts have been established. In particular, peanuts that have been sown early have a long time of emergence, coupled with significantly lower temperatures and ground temperatures, impeded root growth, and insufficient nutrient absorption. Plants grow slowly and are vulnerable to attack by bacteria. Therefore, they must be prevented and treated early. 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. Right amount and top dressing. 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.
In short, only by strengthening the management of seedling stage, on the basis of guaranteeing Miaoquan Miaoqi, appropriate control of the growth of the aboveground part will make it strong and not prosperous, and it will achieve strong seedlings, thick stems, numerous branches, dense sections, and well-developed root systems, which will be beneficial to flower buds. The formation of a large number of conditions for the creation of flowers and flowers to create the basis for high yield.
