Method for preventing corn empty stalk four
The emergence of empty stalks in maize is directly related to environmental factors and planting density. To solve the problem of empty stalks in maize, we should start by improving the environment, establish good ecological conditions, and reasonably adjust temperature, light, water, gas, and fertilizer to reduce Empty stalks of corn increase corn production. There are four ways to prevent corn empty stalks.
Choosing good varieties and selecting suitable varieties with high yield and high resistance suitable for local planting is the primary measure to reduce the empty stalks of corn.
Planting and planting density of different varieties in a reasonable and dense plant should reduce their density when the level of soil fertility is low. If you use the advantages of borderline, large ridge cultivation, close planting should be implemented. The purpose of rational dense planting is to ensure that corn groups have good ventilation and light transmission conditions, and make full use of fertilizer, water, light, and heat resources, so as to achieve multiple panicles, large sticks, and high yields.
In order to strengthen field management, we must rationally apply fertilizers, increase organic fertilizers, and apply nitrogen, phosphorus, and potassium fertilizers in a balanced manner to realize the combination of organic and inorganic fertilizers. In the maize seedling stage, strengthen management, control large seedlings, promote small seedlings, eliminate three types of seedlings, so that the maize population grows robust and neat. In the flowering pollination period, in the event of rainy weather, try to artificially pollinate.
Strengthen the construction of farmland irrigation and drainage facilities, improve the farmland infrastructure, and meet the energy discharge irrigation standards. Use groundwater irrigation to solve the problem of high temperature and drought.
