Like wheat and rice, the mechanized seeding level of corn has been increasing year by year in recent years. In 2012, the mechanization degree of corn planting in the province reached 80.6%. On the eve of the sowing of the new season corn, readers from Fuyang and Zhangzhou sent a phone call to this newspaper, hoping to understand: How can we use more sowing methods to grow corn? To this end, the reporter interviewed He Chaobo, chief engineer of the Provincial Agricultural Machinery Extension Station. The front stalk is well treated The former glutinous wheat cultivar planted by the farmer should match the width of the operation required for no-tillage sowing of corn, ie 4.2 m or 2.1 m, and the surface should be smooth. At the same time, wheat varieties should use dwarf anti-falling varieties to reduce the amount of straw, which is convenient for the corn planter to pass smoothly during operation. The wheat yellow water is poured 3-7 days before the wheat harvest, and the bottom of the corn is planted at the same time. Under normal circumstances, the earthy and heavy plots are poured early, and the loose soil plots are poured late. The control of the armyworm during the growth period of wheat should be thoroughly controlled. In the spring, the herbicide should be sprayed at the appropriate time to inhibit or eliminate the weeds. It is best to harvest the wheat with the combine harvester with the crushing straw device, so that the wheat straw can be thrown and evenly covered; if the harvester does not have the straw crushing and throwing device, the straw crusher should be used to crush the wheat straw, and then evenly spread to adapt The need to sow corn. When the yield of the former glutinous wheat is >500 kg/mu, the amount of straw is too large, and the excess straw should be cleared out of the plot. Seeding time should be reasonable Chief Engineer He told reporters that at present, most of the corn planting in our province adopts no-till seeding method. Whether it is a no-till planter or a small amount of planter, the seeding depth is the ditch depth of the opener. If the farmer sows too early, it is easy to cause corn shrinkage disease during the growth of corn; if it is planted too late, the seedling period will easily form waterlogging when it encounters heavy rainfall. Therefore, June 10-15 is the best sowing time for corn. The seeding amount per mu is 3 to 5 kg, and 4,500 to 5,000 seedlings per mu. Conditional farmers can choose the method of belt-shaped rotary tillage, the depth of rotary tillage is 12-15 cm, and the sowing depth is less than 5 cm. Because of the seeding belt through rotary tillage, the depth of rotary tillage is greater than the depth of sowing, and the straw in the tillage layer acts as a filter screen to separate the accumulated water from the root of the seed. Choose equipment carefully At present, there are many types and models of corn planters. When purchasing a planter, users should choose according to different operation requirements, and also consider the operation performance, safety and adaptability of the planter. He Chaobo suggested that farmers should first consider the horsepower (power) of the tractors they purchase. If it is 55 horsepower, the optional corn planter should be 4-6 rows; if it is 12-18 horsepower, the purchased corn planter should be 2-3 rows. Also check the driller opener form to see if it is suitable for the local soil. In the Huaibei area, corn shovel is planted, mostly after the wheat is harvested, the straw is pulled away, and then the corn is sown. Most of the currently produced shovel seeders are suitable for low-lying machine broadcasts. The large combine harvester harvests wheat, and the cut height is generally above 20 cm. The farmer can use the high ground gap shovel planter; after the large combine harvester, if the straw is chopped and returned to the field, the straw is chopped and returned to the field. Or harvest with a combine harvester with a straw chopping device, while shredding the straw onto the ground, and seeding with a shovel seeder with a weeding device. Farmers should pay special attention to the purchase of products produced by formal enterprises, preferably brand-name products, so that the quality of product manufacturing can be guaranteed. When purchasing the planter, pay attention to the safety of the planter. Check whether the planter is equipped with a safety cover at the transmission site after purchase, and whether there is a safety warning sign in the dangerous part.
