Reasonable use of corn no-tillage planter must grasp the following five points: 1, sowing when sowing. The sowing date of summer corn is generally in the middle and early June. It should be carried out in conjunction with the harvesting operation. After the wheat is harvested, it should be planted on the same day or on the next day to form the process of receiving and broadcasting. It should be sown no later than June 15. 2, enough to plant. One is to pour yellow wheat water depending on the rain conditions from 3 to 7 days before harvesting, so as to create a suitable bottom crop for the summer corn planting; second, it is also possible to pour the head water after sowing the corn, and timely stack the wheat straw after watering. Spread out, so as not to affect the emergence. 3, Strictly control broadcast depth. Seeding depth of 3 ~ 5cm is the most suitable, too deep weak seedlings, too shallow and difficult to emerge. Poor sentiment can be appropriately broadcasted. After sowing compaction, the seeds are in close contact with the soil. 4, adjust the amount of broadcast, reasonable close planting. The following amount should be adjusted to 2 ~ 2.5kg / mu, line spacing adjusted to 60cm (to facilitate the joint corn machine). Compact varieties are suitable for densities ranging from 5000 to 5500 strains/mu, and semi-compact varieties are suitable for densities of 4500 to 5000 strains/mu. Plant spacing depends on the variety and density of seedlings. 5, strict operating procedures. During the sowing operation, strict operating procedures, sowing speed should not be too fast, walking should be even and straight, try not to stop halfway, to achieve uniform under the same kind of cover sowing depth.
