Summer corn can normally mature and must take the necessary technical measures to promote early maturity.
1. Foliar fertilization In the middle period of corn growth, 0.3% potassium dihydrogen phosphate plus zinc and boron micro-fertilizer can be sprayed to promote the formation of corn kernels, improve stress resistance, and achieve early maturity.
2, timely prevention and control of pests and diseases to reduce the harm of pests in the later stages of corn, improve the utilization of light energy, promote the transformation and accumulation of nutrients in summer corn. Therefore, it is necessary to prevent and treat maize brown spot, leaf spot, aphid and corn borer.
3, interlaced male "corn went to the head, strength as big as cattle." After detasseling, the nutrient and water needed for flowering of the tassel can be supplied to the growth and development of the ear. The second is that the male flower is on the top of the plant and some male flowers are removed to prevent shading, which is beneficial to the photosynthesis of corn. So intervening males can speed up the maturation of corn. Detasseling method: One line or one line can be removed one line at a time. The most suitable time for detasseling was that Tassel had just taken out and was able to hold it when the hand was able to hold it. After the end of the meal, all the remaining tassels were removed.
4, in addition to empty plants will not be planting plants, diseased plants removed, both water-saving province, but also conducive to air and light.
5. Suede tanning at the end of corn milk ripening, the temporal lobe on the corn ear is gently opened, so that the corn grain is directly exposed to sunlight, which can promote the nutrient conversion and dehydration of the corn grain and mature 7-8 days earlier.
6, with the strains harvested in the corn wax ripening period, the corn with the root planing, grasping the transport out of the field, placed in the shade of the house or under the tree stand up, it is best to root soil and pour water, in order to maintain The long-term green leaf function promotes the transportation of nutrients in the stems and leaves and increases the grain weight. The storage heap should not be too large, and the stacking time should not be too long. It is advisable to use 15 to 20 days.
