Summer Sowing Corn Management Points
In recent years, due to factors such as late crop harvesting, drought climate during sowing, and poor seed quality at the time of harvest, corn has poor seedlings, irregular cropping, and weak growth. As the saying goes: "Summer competition, autumn disputes" to strengthen the management of corn fields, promote plant growth, ensure late production does not reduce production, it is very important. In the management, we should take the early and the promotion as the center and do the following: Sodium Erythorbate,Sodium Erythorbate Powder,Food Additives Sodium Erythorbate,Antioxidant Sodium Erythorbate SHANDONG BAISHENG BIOTECHNOLOGY CO., LTD , https://www.baishengbioproducts.com
First, dry irrigation irrigation and early irrigation water, jointing water, booting water, grouting water, four key water. According to soil moisture, four waters should be fed 5-7 days earlier than normal sowing maize to meet the water requirement in each growth period and promote the rapid growth of the plants.
Second, early application of early fertilizer culm attack, attack panicle fertilizer, attack grain, make up the foliar fertilizer. Late sowing of maize, due to late sowing, delayed growth, top dressing should be applied 5-7 days earlier to promote growth. At the same time, combined with fertilization of 667 square meters with 0.3% -0.4% of potassium dihydrogen phosphate aqueous solution or 0.2% -0.3% of urea aqueous solution; 1:1 of biogas slurry foliage fertilizer, promote nutrient transport, increase grain weight. Spray once every 7-10 days and spray 2-3 times.
Third, early seedlings, Dingmiao, check seedlings after the emergence of lack of corn seedlings, timely check seedlings to make up for deficiencies, such as the lack of seedlings should be found as soon as possible to fill the seedlings. The seedlings can be set ahead of the 3 leaves in advance, Dingmiao can be ahead of the 5 leaves in advance, reduce nutrient consumption, solve the contradiction between the seedlings compete for water.
Fourth, early prevention and control of pests and diseases The main diseases of corn are rough dwarf disease, smut, stalk rot, etc.; insect pests mainly include corn borer, armyworm, adult worm, earthworm, etc., should be found early, early control, reduce field strains , Insect strains, increase robust strains.
5. Reasonable increase in density Due to the late sowing of maize that misses the best sowing date, it will have an impact on the yield, and the yield can be increased by appropriately increasing the density of seedlings. Usually 10-15% more plants per 667 square meters.
Sixth, timely and late harvest on the premise of not affecting the sowing of crops under the crop, should be appropriate late harvest, to improve the yield and quality of corn have a certain effect, or with stalk harvest, promote grain physiological after-ripening, to increase production.
