It is common to plant corn seedlings in summer. What are the methods to prevent corn seedlings from burning in summer?

Single-seed planting: Single-seed planting can prevent seedlings from competing for fertilizer and hurting roots during thinning, which is beneficial to cultivating strong seedlings. If it is a direct broadcast, it is advisable to use 2 kilograms of seeds per 667 square meters, plant early seedlings and fix seedlings after emergence. Formulated fertilization, reasonable topdressing, reasonable fertilization according to the growth cycle of corn, effectively improving the utilization rate of fertilizer, and fertilizing in two or three times.

Sow early. In the past, there was a habit of sowing corn in the field before wheat was yellow, and wheat emerged after harvest, which was equivalent to prolonging the growth period of corn and generally increasing the yield by 6 ~ 10%, provided that the soil moisture was good, there was labor at home and the weather was meteorological; Meteorological disasters are a great threat to high yield of maize, especially lodging, which is the biggest obstacle to high yield. Therefore, reasonable close planting, selection of lodging-resistant varieties, prevention of lodging and prevention of diseases, pests and weeds can achieve the goal of high yield of corn.

Second, reasonable close planting. Corn is a high-yield crop, but don't plant it blindly for high yield. Reasonable close planting can improve crop characters and enhance the lodging resistance of maize. Water, fertilizer and water are the lifeblood of agriculture. Corn is a fast-growing crop in summer, and the temperature in summer is the highest in a year. At this time, the transpiration is very large, especially at the trumpet stage, which is the key to determine the corn harvest.

Sowing date selection: Everything is the golden time for sowing, and it is also an auspicious day, so is summer corn. Generally, corn is divided into spring and autumn. Your main question is spring, so just say the planting time of spring corn. There is no uniform standard for high-yield corn because of different climate and soil characteristics, but efforts should be made in seed selection, planting, water and fertilizer management and pest control anyway. So, we can do more with less. Selection of varieties. Summer maize varieties should be selected with short growth period. Because summer corn is sown later than spring corn, the biggest problem of summer corn in southwest China is insufficient heat in the later stage.
