Peanuts are widely used and can be used to refine edible oils, non-staple foods, etc. Peanut shells can also be used to make soy sauce. Therefore, peanuts are all treasures. It is good to plant peanuts. Of course, the economic benefits are very good! Now come along with the Hui Nong School to learn about the high-yield cultivation techniques of peanuts!
First, choose the plot, formula fertilize
Choose sandy loam or loam suitable for peanut growth to create a soil condition with deep soil layers and loose layers. Soil testing and formula fertilization, applying sufficient base fertilizer, especially pay attention to the application of decomposed organic fertilizer. Organic fertilizer is a full-price fertilizer, and it is important to pay attention to the application of organic fertilizer. At present, there are few organic fertilizer sources. The bio-organic fertilizers on the market are rich in organic matter, such as phosphate-dissolving bacteria, nitrogen-fixing bacteria, potassium-releasing bacteria and anti-bacteria, which can replace farmyard manure. According to our experience, 2 to 3 kg of potassium dihydrogen phosphate is used as seed fertilizer, not only the seedlings are strong, but also the functional stage of the top leaves can be prolonged, and the deciduous leaves, the fruit rate and the rice yield rate are obviously improved.
Second, ridge mulching, single seeding
The mid-late maturing varieties have a ridge distance of 90 cm and a plant spacing of 20 cm. The mid-early maturity varieties have a ridge distance of 80 cm and a plant spacing of 15 cm. The principle of arranging the spacing of the plants is to exert the productivity of individual plants and to create conditions for the reproduction of the later plants. Using "ANM" cultivation method, the sowing depth is 3cm, and the film is pressed 5cm along the seeding line. The leaf part of the leaf is excavated by the leaf, and the cotyledonary leaves are excavated and the soil is cleared, which promotes the flower bud differentiation of the first pair of side branches, which can increase yield by more than 15%. . Plots with peanuts can be used for seed dressing with ketamine, or with sclerotin (ingredients of pentachloronitrobenzene and calcium hypochlorite), which can also control the occurrence of rickets. .
Third, the main branch cutting, side branch pressure
60 to 70 days after sowing, choose the strong and robust plants after the initial flowering, cut the top of the main stem 5~10cm, the row spacing is 35cm, the plant spacing is 20cm, and then watering in time, pay attention to the soil and ensure the survival. It takes 120 days from cutting to maturity, and 150 to 200 kg of pods can be harvested in acres. At the same time, in view of the fact that peanuts have many irregularities and many needles are not true, the fruiting effect of high-fruit needles is exerted. On the basis of cultivating and cultivating soil, a small bamboo strip or thin iron wire of 20-25 cm length is used to bend into a "door" shape, and the side branches of the peanut are stuck into the soil, so that the branches are close to the ground, so that the high-node fruit needles are sturdy in the soil, increasing the single Number of results. A total of two presses, acres can increase the number of pods 3 to 40%, the breeding multiple can reach more than 100 times.
Fourth, strengthen management, disease prevention and control
As long as the peanut cultivation is controlled in the early stage, the leaves are preserved in the later stage, which can basically capture high yield and high yield. Rainy years or high-fertilizer land, peanuts are easy to grow, conventional drugs such as B9, PP333 and its compounding agents are easy to cause defoliation. According to our experience, spraying PBO, even spraying 2 to 3 times, no leaves, and Can significantly improve the disease resistance of plants. From mid-June, it began to spray 1:2:150~1.80 Bordeaux liquid or Dasheng M-45 and spray copper preparations, mancozebs. Bordeaux liquid is easy to match with low price, has remarkable control effect, and is not easy to produce drug resistance. At present, carbendazim and thiophanate are still used in Daejeon production, but leaf spot disease has developed resistance to such drugs. It is worth noting that when spraying, it is necessary to use drugs to seal the ground between the plants to inhibit the reinfection of the ground bacteria.
The above is the high-yield cultivation technology of peanuts, for your reference, reference, planting or need to rely on experience and science at the same time, together for the high-yield peanuts to act!
