An increase of four peanuts late to ensure high yield
Timely irrigation and fruit filling In the full fruit ripening period, the water requirement of the plant is reduced, and the water absorption capacity of the roots is weakened. If too much autumn rain results in poor drainage, it will cause root rot, stem blight, fruit loss rate, and soil air suffocation. And rotten fruit disease occurs. Therefore, it is necessary to pay attention to clearing the ditch in time, removing water, and eliminating waterlogging. At the same time, it is necessary to timely fill the fruit and water with furrow irrigation to preserve the roots and protect the leaves, maintain the vitality of the leaves, increase the rate of fruit filling, and ensure high yields and stable yields. Control tree growth and fruit growth stability 30 to 50 days after the beginning of flowering, the main stem is 35 to 40 cm high, the first pair of lateral branches is 8 to 10, and the average length is greater than 10 cm. Agents to control the promotion of the next, to ensure that the stem is stable and promote long-term results. Generally, 0.1 kg of B9 solution is used for 50 kg per acre, evenly sprayed on the upper leaves of peanuts. Foliar spray fertilizer to protect the top leaves from the stage of tillering to harvest, only 4 to 6 top leaves of each branch of peanuts, is to maintain the vitality of the whole plant, the basis for photosynthesis. In order to enhance the leaf vigor and extend the functional period, the foliar fertilizer should be sprayed from the later stage of the results and sprayed every 7~10 days for a total of 2~3 times, 500 grams of urea per acre, 100 grams of potassium dihydrogen phosphate. , add 50 kg of water diluted and spray evenly. Prevention and treatment of pest control and harvest of peanuts in the middle and late stages mainly include leaf spot, rust, aphids, cockroaches and other pests and diseases. For leaf spot, the initial flowering period should be sprayed once every 10 to 15 days according to the disease condition, and sprayed 3 to 4 times; for rust, when the diseased plant is seen, the drug should be used, spraying once every 10 to 15 days, Even spray 2 or 3 times. Commonly used agents: 70% thiophanate-methyl wettable powder 1500 times, 75% chlorothalonil wettable powder 600 times. For pests, it should be based on early treatment and treatment to reduce harm. Timely harvesting and increasing yields Because peanuts are generally difficult to see from the outside whether the pods are already full and mature, harvesting too early or late will affect their yield and quality. Therefore, it is especially important to determine the appropriate harvest period for peanuts. A look at the growth period. The growth period of common peanut varieties is about 125 days. Second look at the temperature. When the average day-night temperature is below 12°C, the plants basically stop growing and can be harvested at this time. Three to see plants. Under normal conditions, when peanuts enter the later stage, the plants show an aging state, ie, the tops stop growing, the upper leaves turn yellow, and the base and middle leaves fall off. At this time, most of the pods are full and can be harvested.
