The latest methods of how to prevent the harm of Corn High temperature
Corn is an important food crop in China, and it also has a very large planting area in our country. When planting corn, we should adjust our management appropriately with the change of season. Especially in summer, corn is prone to high temperature harm if it is not managed properly, which will have a serious impact on the quality and yield of corn. So how can we prevent the high temperature harm of corn? Let's take a look at it with the editor.
1. Artificial pollination
After entering the summer, because of the high temperature, the ability of corn to disperse pollination, pollinate and fertilize and bear fruit will decline. Therefore, in the flowering period of loose corn flour, if you encounter weather above 35 degrees. Then we must pay attention to do a good job of artificial pollination, avoid the influence of high temperature, reduce the pollination and fertilization ability of corn, and improve the seed setting rate of corn. When artificial pollination, we should usually collect pollen around 9 o'clock in the morning. Then do a good job of pollination, mainly with picking and teaching, which can effectively improve the maize yield.
2. Reduce planting density.
When planting corn in summer, we must pay attention to control the planting density. Generally, it is mainly planted in wide and narrow rows, because in the case of low planting density, the phenomenon of nutrition and water grabbing between individual plants of maize can be effectively reduced. It can enhance the high temperature tolerance of maize plants and reduce the harm of high temperature. If it is high-density planting, then we should pay attention to the use of wide and narrow rows to improve the permeability of the field and reduce the temperature of the field. For the purpose of planting robust plants, the growth ability of maize plants was strengthened to ensure the yield and quality.
3. Rational fertilization
Fertilization in summer is also very important, we should appropriately increase the amount of farm fertilizer, focusing on base fertilizer to promote the early development of plants. Then pay attention to the use of trace elements, after the emergence of maize seedlings should be appropriate early application of seedling fertilizer to promote strong stems. During the period of big trumpet mouth of corn, panicle fertilizer was the main topdressing. Then it should be combined with irrigation to improve the nutrition of the plant. Finally, foliar fertilizer should be properly applied in summer, which can not only reduce the temperature and humidity, but also meet the nutrition needed for the growth of maize.
4. Watering at the right time
In the high temperature environment in summer, it is usually accompanied by drought. Therefore, after entering the summer, we should pay attention to proper watering, which is the simplest way to cool down. And after watering, corn can also absorb water, enhance evaporation, and effectively reduce the canopy temperature. So as to reduce the harm of high temperature and the respiratory consumption caused by high temperature. However, watering should not be too much, should be mainly irrigated with small water, not too much watering, otherwise it is prone to waterlogging. It is best to sprinkle irrigation, sprinkling water directly on the leaves, can effectively achieve the cooling effect.
The above is a brief introduction to how to prevent the harm of high temperature in corn. The high temperature harm of corn has a great impact on its yield and quality, so we must pay more attention to it. That's all for today's introduction. This article is for reference only. I hope it can help you all.
