1. The seedlings are complete and strong. Denong 7 has flexible planting density, ranging from 4000 to 6000 plants per mu, and has no special requirements for seedling retention. The seeds are half-horse-toothed, which can be fertilized with the seeds, with strong soil arching ability and high germination rate. This variety uses enough imported seed coating agent without secondary coating, and the seedling emergence is stronger, more uniform and faster.
2. Harvest saves working hours. This variety is disease-resistant and lodging-resistant, with less ear leakage and no need to peel when harvesting mechanically, which saves labor and time. After harvest, there is less water in the ear, the seeds are deep, the seed yield is as high as over 90%, and the seeds are dehydrated quickly, so they can be directly stored and air-dried. Large grain growers can arrange threshing and selling time according to market conditions. If the harvest is properly delayed to about 106 days, corn can be harvested by machine like wheat, and the whole production process in the summer corn area of Huang-Huai-Hai is mechanized.
From 2008 to 2065438+00, he participated in the general regional test of maize summer sowing group in Shandong Province, with an average yield of more than 650 kg per mu. With high-yield cultivation techniques, the yield potential can reach more than 1000 kg.
