Topping: Cut some leaves in the upper part of the corn cob, and the topping has a certain influence on the yield. The earlier the cutting is, the more corn is reduced. The corn grouting nutrient is mainly provided by these leaves. Therefore, the topping should not be earlier than the initial stage of waxing, and 1 to 2 corn leaves should be left in the upper part of the stick.
Cut off the effective rod ear: This method is applicable to single ear varieties. In addition to the upper rod ear, the second and third sticks of corn plants are late, and the silk is late, and the fine stings should not be removed. This can save nutrients and attack the big ears and promote early maturity.
Suede drying: When there is a layer of “hard shell†in the middle stage of corn wax, the loquat leaves are gently opened, so that the whole grain is exposed, so that the sun is exposed to the sun, but in the normal mature year, it is not suitable for molting, low temperature early frost year, The greedy green plot, the suede drying method can promote corn early maturity for a week, and increase production by about 7%.
