At present, corn has generally been jointed and entered the vegetative growth and reproductive growth at the same time, is the period of absorption of nutrients, the most water, but also determine the panicle, grain and achieve a high yield of the key period, for this corn on the management of the late stage proposed the following Suggestions: Disposable Silicone Tourniquet,Silicone Silicone Tourniquet,Disposable Tpe Tourniquet,Medical Disposable Silicone Tourniquet Shaoxing Jenston Medical Products Co., Ltd. , https://www.sxjcmed.com
First, drought and flood control. After the jointing of corn, it will enter the period of vegetative growth and reproductive growth at the same time. It is the critical period for attacking big spikes, and it is also the frequent occurrence of severe weather such as drought and hurricane. At this time, drought and flood prevention should be carried out together so that the drought can be poured in time. Water, old can drain in time.
Second, heavy ear fertilizer. The big bell-mouth period is the critical period for corn demand and fertility, and the lack of fertilizer during this period seriously affects the corn yield. Therefore, it is necessary to re-apply panicle fertilizer and supplement grain fertilizer to ensure that the corn is not deferred during the later period, and the panicles and grains are more mature at the time of maturity. Grain weight and good quality. Generally, when the 8-10 leaves of the plots are applied, 25 kg of urea is applied per mu, and about 10 kg of urea is applied during the tasselling period.
Third, timely prevention and treatment of diseases, insects, weeds. In the middle and later stages of corn, corn borers, cotton bollworms, aphids, leaf spot diseases, bacterial wilt, and sheath blight are the most serious hazards. In particular, corn borers and aphids occur every year and must be controlled and sprayed with 50% methamidophos 1000 times solution. The major causes of spot and bacterial wilt are prevention. The main purpose is to strengthen the cultivation and weeding in the field, drain the water after the planting, disperse the wet, reduce the temperature, and maintain the microclimate in the field.
Fourth, timely harvest. Timely harvesting can ensure that corn has sufficient grouting time, which is an effective measure to increase grain weight and increase production. The standard of corn maturation is the disappearance of milk, and the general variety should be harvested about one week after the yellow leaves have been harvested.
