Supplemental fertiliser for flower grains. Nitrogen fertilizer was mainly applied to improve leaf photosynthetic efficiency and prolong leaf functional period. 10 kg of urea can be applied per mu and applied before rainfall to improve fertilizer efficiency. Foliar spraying of potassium dihydrogen phosphate, urea and other mixtures can also be applied to prolong the photosynthetic time of leaves, promote the accumulation of photosynthetic products, and increase grain weight.
Prevention of pests and diseases. The corn field has high humidity, high temperature, and more wind and rain weather, which is conducive to the occurrence and spread of pests and diseases.
Break off the excess ears. At present, most of the corn varieties are single-ear varieties, and if multi-ear plants are found, personnel should be organized to break off the excess ears as soon as possible, and only 1-2 ears of corn should be kept for each plant to avoid consuming nutrients.
Late harvest at the right time. Late harvesting at the appropriate time can prolong the filling time, which is conducive to the accumulation of dry matter, give full play to the high yield potential of varieties, increase grain weight and improve yield. It is recommended that general plots be harvested at the end of September and early October, and high-yield plots around October 10.
