Six Technical Points for Alternate Leisure Cultivation of Corn in Wide and Narrow Rows
1. Site preparation: In the first year of cultivation with wide and narrow rows, it is necessary to carry out comprehensive extermination and rotation cultivation of the plots. Site preparation must be carried out in the fall. Conditional farming can be applied to the fields. With one-time fertilization, appropriate amount of base fertilizer is applied at one time depending on the fertility of the soil. In the second year, it is only necessary to spin the width of the fallow, which is the first year of the fallow. After soil preparation, when the topsoil has a dry soil layer of about 1 cm, a double-row V-type ballast is used for repression. 2, seed treatment: 5-7 days before sowing to dry the corn seed, and often flip, continuous drying for two days. At the same time, the seeds are coated with a suitable seed coating agent. 3. Sowing: When the temperature of the plough layer soil is 10cm at 10°C, it can be sowed. On the basis of the fall-turned land, the original 65cm uniform spacing is changed to 40cm and the 90cm width of the blank belt (in some regions, the distance between the seedlings and the blank belt is not equal), using a double precision seeder to implement 40cm Narrow rows with precision on-demand or accurate half-segment encryption seeding. After sowing, when the soil appears about 1cm of dry soil layer, the seedling belt is heavily repressed by the seedling weighted repressor, and the droughty land should be repressed immediately after sowing. After sowing, we must promptly use high-efficiency, low-residue herbicides to seal and weed the soil before seedling emergence. 4, deep loose fertilizer: Before the arrival of the rainy season in mid-June, with a deep loose fertilizer machine in the 90cm wide belt to implement about 30 ~ 40cm deep loose fertilizer, using a one-time fertilization of the land, only for deep loose operation. 5. Diseases and pests prevention and control: The techniques for controlling diseases and pests of broad and narrow rows of corn are the same as those for conventional corn cultivation. 6, high retention tinea: When harvesting in the fall, it is necessary to keep the roots high, leaving the larvae at a height of about 30 to 40cm. Practice has shown that the alternating leisure and planting techniques for maize with wide and narrow rows have a strong production growth advantage. The use of this technology with significant economic benefits can increase production by 3% to 5% in the year, and can increase production by 10% to 15% if implemented continuously for three years.
