Method 1: Cultivating and weeding:
The growth of the peanut root system and the development of the pods both require the soil to have an appropriate amount of moisture and porosity. Timely cultivating, weeding and loosening the soil not only benefits root growth, but also promotes the pegs penetrating the soil and setting pods.
For spring-sown peanuts, cultivating and weeding is generally done 2-3 times. The first cultivation after full emergence should be shallow, to promote the development of the first pair of lateral branches; 8-10 days after that, carry out the second weeding and loosening of the soil, which should be done with appropriately deep hoeing; the third is carried out at flowering and before the rows close, and should be done with appropriately shallow hoeing to avoid damaging the peg. Especially on hilly red loam dryland, where the soil layer is compacted, timely cultivating, weeding and loosening the soil has an even more pronounced effect on promoting peanut growth and flowering and fruiting.
Method 2: Earthing up the peanuts:
Earthing up and mounding the base means that during the last cultivation, soil from between the rows is mounded toward the base of the plants, with a thickness of 2-3 cm being appropriate; this shortens the distance between the pegs and the ground surface, making it easier for the pegs to enter the soil. Pressing the plants with fertilized soil means loosening the soil in the furrow, splashing on diluted manure water and mixing it evenly to make fertilized soil, which should be moderately dry and wet. Then press the fertilized soil onto the center of the peanut clump, so that the pegs can enter the soil and the ovary stalks can swell and set pods.
Method 3: Pinching off the growing tip of the peanut main stem:
At the early flowering stage of peanuts, pinch off the growing tip of the main stem; this can make nutrients relatively concentrated, and both the pod-setting rate and pod weight increase significantly. The method is: at the point halfway above the highest branch of the main stem, use scissors to cut off the growing tip of the main stem. Choose a sunny day to do this, the cut should be smooth, and after pinching, apply a quick-acting fertilizer in time. For over-luxuriant peanuts, besides pinching off the growing tip of the main stem, the side tips of the first-order branches should also be pinched off.
Method 4: Timely drought relief and waterlogging prevention:
During the flowering and pegging stage, the plants grow and develop rapidly, the temperature is high, and leaf transpiration is vigorous; this is the stage of the peanut's life when it needs the most water. If drought occurs at this time, furrow irrigation must be carried out in time to keep the soil moist and promote flowering and fruiting. If there is continuous rain, the furrows should be cleared and drainage carried out in time to prevent excessive stem and leaf growth and rotten pods.
Method 5: Spraying fertilizer on peanut leaves:
During the flowering and fruiting stage, the peanut's nutrient uptake increases sharply, so a 0.5% potassium dihydrogen phosphate solution should be sprayed 1-2 times. For leaves that turn yellow, a 1.5% urea solution should also be sprayed 1-2 times to prevent premature aging. Peanuts are sensitive to calcium, so except for calcareous soils, when growing peanuts in general soils, a 2% superphosphate extract should be sprayed on the leaves once each at the early flowering stage and the full flowering stage, to meet the peanut's need for calcium, and the yield-increasing effect is significant. For diseases and pests such as rust, leaf spot and aphids, comprehensive measures should be taken and control carried out early.
