How to overcome peanut weight

Although peanuts should not be weighed heavily, the following four levels should be strictly controlled when the main producing areas for large-scale spring planting must be cultivated.

1, site preparation. The land preparation must be meticulous, and it must be done in autumn and evening, deep-turned to 30 centimeters, and meticulously chopped many times to ensure that Panasonic works on the soil, with good permeability, and ridges and compactions in autumn. Through the low temperature in winter, it can kill the fungus that causes peanut stem rot and root rot in the soil and reduce the occurrence of pests and diseases.

2, fertilization off. Peanuts must be grown with organic fertilizers in combination with 4,000 to 5,000 kilograms of high quality farmyard manure in autumn. Phosphorus and potash fertilizers were used as sowing, 15 kg of ammonium phosphate per acre and 8 kg of potassium sulfate. In the first half of August, 2% potassium dihydrogen phosphate was used for foliar spray and twice, and at the same time, the special microbial preparations containing nitrogen-fixing bacteria, phosphate-solubilizing bacteria and potassium-releasing bacteria, and moderate amounts of trace elements were used to prevent diseases. The effect is significant.

3, species off. Strengthen quarantine, it is forbidden to introduce from the ward. Select high-resistance varieties and replace them in time. Peanut hull selection before sunny weather 2-3 days. Combining with peeling and shelling, the first species with large grain, bright skin color, high fruit filling rate, good uniformity, clear texture, moderate size, beautiful appearance, germinating power, and high germination rate are selected.

4, management off. After emergence, if there is a phenomenon of lack of seedlings, it is necessary to regenerate seedlings. After the seedlings are established, clear seedlings are planted, and the seedlings in the roots of the seedlings are picked up by hand to expose the two cotyledons. About 15 days after the green bark, the soil is refilled. Three times of cultivating and weeding at the seedling stage, sapling stage and flowering stage, the first cultivator should be shallow, to prevent the stalks from being buried too much, and to affect the development of lateral branches, as long as the topsoil is loosened, the weeds can be removed; the second cultivator is Nodule formation period, the cultivator can be slightly deeper, generally about 6 cm; the third cultivator during the flowering period, the cultivator should be extra careful to avoid damage to the fruit, cultivating depth of 5 cm. That is, to master the principle of “light, deep, and shallow”. It is advisable to use 3 cm for 15 days after flowering and not to over-thickness. Strengthen the prevention and control of pests and diseases and find out that the disease is prevented and prevented early.
