How can corn cultivation be high-yield? These three conditions must be considered when selecting corn varieties.
There are many varieties of corn. Before planting corn, farmers will carefully select the corn varieties that are suitable for their own sowing. Because the quality of a corn directly affects the yield of corn, the yield will directly determine the income of the year. This year's corn market is still pretty good, the price of corn has been maintained at around 1 yuan. So how should farmers friends choose corn varieties to produce high yields?
Three necessary considerations for selecting corn varieties
1. Soil condition
The corn varieties on the market today are all high-yield varieties, but not all high-yield varieties are suitable for planting on different soils. Therefore, we should look at our soil conditions and whether irrigation is convenient when selecting corn varieties. If the local soil is rich in fertility and irrigation is convenient, then you can choose a variety with a longer growth period. For soils that are poorer and more inefficient for irrigation, you should choose a short growth period, strong anti-barren ability, and strong drought resistance. Variety.
2, the wind size
During the planting of corn, it is easy to cause the corn to fall due to the wind. The corn lodging has a great influence on the yield and quality of the corn. When harvesting, only the artificial harvest can not use the harvester. This year, the corn of a grower appears to be lodging. It takes time and effort to get the corn down one by one. If you use a harvester, you can take all the corn back home for half a day. The lodging of his corn is mainly related to the dry weather this year. The water is not timely, the straw is too thin, and the wind is blown down. Therefore, for areas with relatively high wind power, it is best to choose varieties with strong lodging resistance and relatively short plants, and if the wind is relatively small, then you can choose corn varieties suitable for close planting.
3, planting time
The sowing time of corn is early and late, some areas are planted in spring, and some areas are planted in summer. For areas planted in spring, because the temperature is just warmer, the seedlings will be very slow, so you should choose to produce fast and resistant. A variety of cold ability and high resistance to pests and diseases. For areas planted in summer, when the temperature difference is small and the air humidity is small, you should choose a variety with high drought resistance and high heat resistance.
The above grower said that the corn variety he planted is Zhengdan 958. The lodging resistance of this variety is still very good, but the lodging phenomenon this year has a lot to do with the weather this year. The weather is hot and dry. The price of corn in the first half of the year is very low. Many people prefer that the corn will not be watered, so when a corn is about to mature, a wind will cause many people's corn to fall to the ground. This is what his family is like. Well, although it took some effort to collect corn, it did not have much impact on corn production.
Therefore, to judge the quality of a variety, it is necessary to choose according to the local situation. The corn varieties of others are high-yield, and the grain may not be harvested at home. Therefore, it is very important to choose corn varieties according to local conditions. To understand the soil of your own, in order to choose the corn variety that is really suitable for your own land, I hope that the content shared by Xiaobian can help the majority of growers.
