Maize produces a high yield, and good seed is the key. In the corn planting season every year, many farmers’ friends are looking for corn varieties to get a good harvest in the fall. Then, what problems should farmers pay attention to when buying corn varieties?

First, select seeds according to the conditions of thermal resources. Generally, long-growing maize varieties have good yield performance and great potential for yield increase. However, excessively pursuing high yields and using maize varieties that have grown too long will result in insufficient maturity of the corn and inadequate kernels, affecting the nutrition and quality of the corn. Therefore, to select corn varieties, it is necessary to ensure normal corn maturation, but can not affect the timely sowing of the crop. The height of the terrain is related to the ground temperature, and the temperature of the ground is high. It is advisable to choose a late-maturing variety or a medium-late-maturing variety with a long growing period; a moderate-late-maturing variety is suitable for the flat growing season; middle-early-maturing varieties should be selected for the alfalfa.

Second, according to the local production and management conditions selected species. The high yield potential of corn varieties is related to the production and management conditions. High yield potential varieties require good production management conditions, and the production potential has lower varieties, and the required production and management conditions are relatively low. Therefore, in regions with high production management, fertile soil, and abundant water sources, corn varieties with high yield potential and large potential for yield increase can be selected. On the contrary, we should choose varieties with lower production potential but better stability.

Third, according to the former planting seed selection. The increase in yield and income of maize varieties is directly related to the cultivation of the former loquat. If the former is planted with soybeans, the soil fertility is better, and high-yielding species should be selected; if the former is planted with corn and grows well and yields, the species can be continued to be selected; if the former is infected with certain diseases, When selecting seeds, avoid varieties that are susceptible to the disease.

In addition, the same species can not be planted continuously in the same plot for three or four years, otherwise there will be land barrenness and variety degradation.

Fourth, according to disease selection. Disease is the enemy of corn production, mainly related to the soil. The soil nutrients are not balanced, the ground temperature is not normal, and species that are not suitable for this condition should be avoided when selecting the species. For example, "Denghai 9" corn is suitable only for the growth of soils with a balanced soil nutrient and a high degree of ripening.

Fifth, seed selection according to the appearance of seeds. The purity of corn varieties and the quality of the corn have a direct impact on the level of corn production. When the purity of corn seed (purity 98%) declines by 1%, its yield will drop by 0.61%. The selection of high quality varieties is a good guarantee for achieving high yields in corn. The high-quality seed bags are sealed at one time, with the name and detailed address of the seed company and telephone; the date of production, purity, clarity, moisture, and bud rate specified on the seed label are clear; the shape, size, and color of the seeds are neat and consistent.

Sixth, according to the local precipitation and accumulated temperature selection. According to experience, the amount of snowfall was small in winter and cold in winter last year. In the second year, there will be more rainfall in summer, and the accumulated temperature will not be high. For varieties that grow too long, the accumulated temperature is not enough and often affects maturity. On the contrary, in the winter of last year, the amount of snowfall was heavy and the winter was very cold. In the following year, the summer rainfall was generally less and the accumulated temperature was higher. Therefore, varieties with strong drought resistance should be selected, and the middle and late-maturing varieties can be properly planted in the depression.
