To grow good spring corn and strive for a good harvest in the autumn, we should master the following measures: Select good varieties: spring corn should be selected from fertility of more than 112 days, with well-developed root system, compact plant type, red leaves, strong growth, strong resistance, single ear, and large grain type, such as Nongda 108 and Shen 29 Tang Kang 8 and so on. Seeds should be sowed before sowing, remove the seeds of small grains, diseased grains and alfalfa seeds, drying seeds for 2-3 days, can enhance the seed's ability to absorb water, early emergence, improve seed purity, reduce seedlings and improve the uniformity of seedlings. Promote seed coating: uncoated seeds, require 50 grams of A bell, add a "must be more" 20 kg corn seed mix, there is the prevention and control of underground pests, the effect of early emergence. Choosing the best sowing date: Spring corn requires suitable sowing date, early spring in May, spring and autumn after autumn tilling, winter irrigation, and early spring should be rolled up. High-yield fields can be sown in due course, 5 On the 5th to 15th of the month, favorable corn yields. The general field sowing date is from April 25 to May 5. Increase fertilization material: increase phosphorus, potassium fertilizer, adjust the ratio of nitrogen, phosphorus and potassium. 1, 1200 kg of corn per mu, applying 20 kg of diammonium per acre, 25 kg of urea, and 15 kg of potassium sulfate to achieve comprehensive fertilization. The ratio of NPK is 1:0.7:0.5. 2, fertilization time method: sowing 70% 0 fertilizer, plus all phosphorus and potassium fertilizer one-time application or side ditch deep, the other 30% 0 fertilizer, one-time topdressing in the 10 leaf exhibition, seedling side 15 cm, depth 15 cm. 3. Density of planting types: spring sowing maize promoted such as row spacing and sowing, Nongda 108, Shen test 29, Tangkang 8, spacing 1.8 feet, plant spacing 0.95 feet, 3500 acres of seedlings. High oil 115, spacing 2 feet, spacing 1 foot, 3000 seedlings left mu. 4. Seeding techniques: Villages with conditions, advocating machine seeding or sowing on the second floor, sowing volume 4 pounds/mu, seed and fertilizer separation, fertilizer applied to the seed 3-4 cm below, to prevent burning seedlings, can promote Seed roots under the bar. The unconditional small dice can be ditched, and the seeds are sprinkled with seed, and the seeding volume is 5-6 pounds/mu. By mastering the above measures, we will set up a high-yield shelf, and we will be able to obtain the ideal corn yield in the autumn.
