First, the prevention and control of pests and diseases: The main pests and diseases that damage peanuts in this period include leaf spot, rust, cockroach and cotton bollworm. If they are not controlled, they can easily cause leaf shedding and reduce the area of ​​green leaves.
1, prevent disease. In order to control leaf spot and rust, and to extend the functional period of the leaves, after the onset of disease, according to the disease conditions, the use of carbendazim, thiophanate-methyl, mancozeb, chlorothalonil and other agents for foliar spraying twice to four times Control, spray two times interval 10-15 days.
2, pest control. If larvae are found to be harmed during the growing period of peanuts, piers may be treated with methyl isophosulfide or phoxim in solution. The high temperature and humidity in the summer will benefit the occurrence of cotton bollworm. After the prevention and control indicators are exceeded, new pesticides such as Proteobacterium, Insect Overlord, and Thousand-thousands can be used to prevent and cure.
Second, spray foliar fertilizer: Peanut spray foliar fertilizer can maintain leaf vitality. Peanut pods inflating period is the period when peanuts need to peak, in order to prevent defertilization, extend the functional period of the leaves, and increase the fullness of the pods, the leaves can be sprayed once every 7-10 days in the later stage of the scab, too much fertilizer, chlorophyll, etc. leaven.
Third, timely spray growth regulator: In the early stage of scarring in order to prevent plant length, maintain a high and stable effective leaf area, increase the photosynthetic rate, increase the transfer rate of photosynthetic products to the pod nutrients, can be in the peanut ridge before and after the foliage Spraying paclobutrazol, peanut-bamboo, Zhuang-Shen-an and other growth regulators for chemical control.
IV. Drought and Watering: If drought occurs during the period of peanut pods and pods maturation, they should be drenched and irrigated immediately to ensure normal growth and development of peanuts and ensure high and stable yields.
V. Must be harvested in a timely manner: cultivating once in 15 days before harvesting, timely harvesting before the arrival of frost in early September, or harvesting 4 days before the second frost arrives after the first frost. Special attention should be paid to preventing frost and fruit. After harvesting, it should be dispersed and aired in the field for 7 to 10 days. The stems should be turned once every 3 days to ensure the moisture reaches 9%. Early-maturing varieties of peanuts should also be harvested within 7-10 days of meeting their growth period to prevent seeds from breaking their dormancy and germinating in the soil.
6. Antifreeze and Frost Protection: After harvesting peanuts, it is necessary to prevent frost. In the event of frost, frozen fruit will appear, the oil content and germination rate will decrease, and the quality will deteriorate, resulting in lower income. After the peanuts are harvested, the moisture content must be reduced in time. The specific measures are to dry in the ground after harvesting for 7 to 10 days in a timely manner so that the water content of the peanuts can reach 9% or less. Do not pull back home immediately after harvest, stacking up, due to high humidity, high temperature peanuts, can not be timely drying, mold and germination will occur two days, not only affect the quality, but will reduce income.
