This period of time from tasseling to maturity is known as flowering. The central task in flower pellet management is to create a good growth environment for pollination and fruition, increase photosynthetic efficiency, extend the physiological activity of roots and leaves, prevent premature aging, and prevent lodging. To achieve more grain, grain weight, grain full, high yield purposes. There are mainly the following management measures. First, the top-dressing of grain-fertilized corn in the heading period is insufficient, and when there are defertilizers in the later period, it is necessary to top-dress the flower-grained fertilizer to promote corn grain filling, grain weight, and high yield. There are three principles to follow fertilizer. One is to catch fertilizer early; the second is to be appropriate, should be determined based on fertility, corn growth; Third, can be sprayed with 0.4% potassium dihydrogen phosphate spray 80-100 kg per 667 square meters. Second, the drought-fighting and flooding flowering period is the peak period of water demand for corn. If water shortage occurs during this period, it will affect the formation of grain and the grouting is not full, resulting in bald head, lack of grain, grain lean, and reduced yield. Therefore, timely irrigation should be performed in case of drought to meet the moisture demand of corn grouting. However, in the later period of corn growth, the vitality of the root system gradually declines, the degree of phlegm resistance gradually weakens, and it is necessary to drain the larvae immediately in case of heavy rainfall or continuous rain. It is better to cultivate the low-lying fields after the row, to eliminate the compaction, loosen the soil, and promote ventilation. Extend root vitality. Third, to prevent the lodging of fallen corn has a great impact on production, so measures should be taken to prevent it. One is to urge Miao Dunshi to be strong; the other is to cultivate cultivator soil, increase the number of supporting roots, and increase the lodging resistance; the third is to spray potassium dihydrogen phosphate on the basis of increasing potassium fertilizer on the basal fertilizer to enhance the toughness of the plant. However, during the corn growing period, it encountered irresistible storm attacks and caused lodging, so active remedial measures should be taken. If lodging occurs after the jointing, cultivators should cultivate the soil and allow the corn to recover. When the corn is lodging after tasseling, it should be manually lifted and earthed in time to reduce losses. Fourth, prevention and control of pests and diseases to strengthen the prevention and control of corn pests, corn, large and small spot, corn borer, it is timely to control. V. Appropriate late harvest without affecting the conditions of multiple cropping, can appropriately postpone the harvest period, increase corn grain weight, increase production. When the corn glutinous rice leaves are dry and loose, and the grain becomes hard and shiny and golden yellow, it is the ripening period of corn, and the harvesting yield is the highest at this time.
