Choose "insurance" species, not "fresh" species The so-called "insurance" species is a locally grown seed that has performed well for at least two years. The so-called "fresh" species is a species that has not been planted locally or that has performed well for only one year because the varieties that perform well in the first year Must perform well in the second year. Seed selection according to soil conditions For plots with good water and fertilizer conditions, we must choose dense varieties and plant them in accordance with the density requirements of the varieties, because increasing planting density is one of the main ways to increase corn yield. For the plots with normal or poor fertilizer and water conditions, it is not suitable to choose dense varieties, and the general planting density should not exceed 3,500 plants / mu. Proper growth period Too large or too small can cause yield reduction. Choose the variety that just disappears when the corn is harvested (that is, nails cannot squeeze water out of the middle and lower parts of the grain). Do not rely too much on the growth period on the packaging bag, because the same variety is in different regions. The childbearing period may be different. Seeds containing pesticides in the coating agent are preferentially selected. When purchasing corn varieties, we must pay attention to their resistance to stress. Mainly refers to the variety's disease resistance, fall resistance, drought resistance, cold resistance, and strong resistance varieties. Generally stable production. To buy seeds from reputable seed companies Because coated seeds containing pesticides, the pesticides in their coatings kill underground pests in the early stages of corn growth, which is the most cost-effective way to control underground pests. Before buying seeds, you must check the credibility of the seed company, and try not to buy seeds produced by seed companies with a bad reputation or after-sales service. Purchase seeds must go to the designated sales point to buy Regular seed companies have designated sales points for their varieties, because the quality of seeds sold at designated points is generally guaranteed. Don't try to buy seeds from unknown sources cheaply. Disclaimer: Some articles on this website are transferred from the Internet.
