One is scientific fertilization.

The general principle of peanut fertilization is to apply more organic fertilizers, less chemical fertilizers, organic-inorganic combination, quick-acting slow-release combination, and smart application of functional fertilizers according to local conditions.

Acidic soil can be added with physiologically alkaline calcium-containing fertilizers such as lime; continuous cropping soil can be added with lime nitrogen and biological bacterial fertilizer; peanut rhizobia fertilizer can be added to lower fertility gravel sand, coarse sandy loam and stubble soil Nodule nitrogen fixation ability; increase the application of biological potassium fertilizer in peanut high-yield fields to promote effective release of soil potassium. Through the application of biological fertilizers, the amount of chemical fertilizers can be reduced, heavy metal pollution and the accumulation of nitrous acid can be controlled.

The second is scientific watering.

Spring peanuts and summer peanuts sown at foot moisture generally do not need watering at the seedling stage. Appropriate drought is conducive to the development of the root system, improves the drought and waterlogging resistance of the plant, and is also conducive to shortening the first and second internodes, making it easier to pierce the fruit needles Full fruit rate; drought occurs during the seedling stage of wheat peanuts, so water should be timely to protect the seedlings.

The mid-growth period (flowering needle period and pod setting period) is the period when peanuts are most sensitive to water and also the period when the water demand is the largest in their life. Drought in this period has a great impact on yield. When the plant leaves wilt around noon, water should be timely water.

In the late growth period (full fruit period), water should be irrigated with small water in time to prevent premature plant senescence and Aspergillus flavus infection. Watering should not be carried out during the high temperature period, and it is necessary to prevent the accumulation of water in the field, otherwise it is easy to cause rotten fruit, and it is not suitable to directly irrigate with low temperature well water. The peanut fields in the south or in areas with a lot of rainfall should be smooth in the "three ditch" to prevent water damage.
