My town is a large agricultural town, and it grows 18,000 acres of corn all year long. The high yield of corn must be matched with high-yielding cultivation techniques. Combining with my town's actual practice, the high-yielding maize cultivation technology will be summarized as follows: 1. Select high-yield and high-quality new hybrids: select high-yield and high-quality hybrid hybrids with large grains, high grain weight, strong disease resistance, moderate growth period, and compact or semi-compact plants. 2. Timely sowing: sowing from March 10 to 25th. 3, seed treatment germination sowing: the use of high purity, high clarity, full of seeds. Sowing before sowing 2 to 3 days, soaked with warm water of 50 ~ 55 °C for about 2 hours, picked up the filter dry, keep warm in the place above 20 °C germination to powder mouth can be sown. 4, nurturing strong seedlings transplanted in a timely manner: the use of film fertilizer ball seedlings, corn floppy disks and other strong seedlings. Transplanting leaves were 3-4 leaves. The seedlings were graded and transplanted with mud. When planting, the pots were made flat and the two miscellaneous nests were transplanted in a directional manner. The old weak seedlings were not planted and they should be planted after planting. The roots clear the manure, and the lack of seedlings should be promptly filled after planting. 5. Reasonable dense planting: Generally, the compact planting cultivars are planted with 2800-3000 strains of acre, 2600-2800 strains of semi-compact acre, and 2500-2600 strains of loose acre. 2 meters open corn spacing 50 to 60 cm. 6, formula fertilization: corn fertilization is the basic fertilizer and tapping fertilizer, see Miaoqiao fertilizer and jointing fertilizer. Mu with 35% compound fertilizer 30 kg or 50% BB fertilizer 20 to 25 kg, plus 1500 kg of livestock manure water, in heavy acid and calcareous soil plus 1.5 kg of zinc fertilizer for the base fertilizer. Apply rooting fertilizer during transplanting. After transplanting, 500 kilograms of manure water and 3 kilograms of ammonium bicarbonate should be used as seedlings for seedlings in the 5-leaf period; 6 to 7 leaves should be used for 500 kilograms of urea and 10 kilograms of urea. For jointing fertilizer, 10-11 leaves large bell mouth mu of livestock and manure water 1500 kg plus urea 15 to 20 kg for attacking manure. It was found that the land of defertilized premature aging can be used as a granular fertilizer with 5 kg of urea per mu or foliar spraying with 150 g of potassium dihydrogen phosphate and 500 g of urea. 7. Strengthen integrated pest management: Choose a variety with strong disease resistance or light disease, implement rotation cropping, increase potassium fertilizer, etc. to improve the disease resistance of plants, eliminate corn plant residues, kill overwintering larvae, remove dry Heart seedlings can reduce pests. Pay attention to the timely control of corn sheath blight, size spot disease, ground tiger, corn borer, large borer and so on. The above pests can be controlled by carbendazim, Jinggangmycin, imidacloprid wettable powder, Jiegong water spray.
