In order to grow and plant a good type of summer corn and effectively improve the quality of sowing, the following technical opinions are specifically proposed:

1. Inspect seeds in time and use soil and soil to ensure normal emergence. For the broadcasted plots, it is necessary to publicize and mobilize the masses for field investigation, and find that the lack of species is timely soaked and replanted. In particular, the high yield of summer maize to create a field must be investigated on a block-by-block basis. At the same time, the plots of hard-seeded live and rotary sowing should be covered with soil and soil in time to suppress the damage and prevent the seeds from floating to ensure the normal emergence of corn.

2, to ensure the density of seedlings, and promote the wide and narrow row planting mode. In terms of density of seedlings, high-yield plants must be planted to achieve a seedling density of 5300-5600 for a hundred mu of cultivated land, a density of 4500-5000 strains for a million mu of demonstration plants, and actively promote wide-narrow planting to improve ventilation and light transmission in the fields. Harmonize the role of groups and individuals. A planting pattern with a width of 70 cm, a narrow row of 50 cm and a plant spacing of 20 cm was used. In the event of a lack of seedlings and ridges, the seedlings will be planted around the seedlings or around the seedlings to make up for the number of acres.

3, stage fertilizer, a promotion in the end. In this year's summer corn fertilization, in accordance with the requirements of formula fertilization, 1/3 of the nitrogen fertilizer and all of the phosphorus fertilizer, potassium fertilizer, trace fertilizer, and organic fertilizer are applied during the seedling stage; during the big bellmouth period, the remaining nitrogen fertilizer is re-applied. For high-yield research fields, it is required that the general Mushi quality soil-fertilizer 2000-3000 kilograms or granular organic fertilizer bags 80-100 kilograms. At the same time, a 0.4-0.5% potassium dihydrogen phosphate solution is sprayed during the big bell mouth period to ensure the nutrient requirements for corn growth.
