Method for high yield of late-sowing summer corn and special simple corn detasseling device

Abstract

The invention belongs to the technical field of methods for high yield of late-sowing summer corn, and discloses a method for high yield of late-sowing summer corn and a special simple corn detasseling device. The method is mainly and technically characterized by comprising the following steps that a medium-maturing or medium-early maturing variety or a kernel direct-harvesting variety with earlyspinning is selected; the depth of a furrowing blade and the depth of a corn seeding plough of a corn seeding and fertilizing machine are adjusted to enable the depth of each seeding furrow to be 8-10cm and the soil buried depth of seeds to be 2-3 cm so as to ensure shallow burying and early seedling emergence and keep the soil moisture not dry at the same time; the width of each foot of the cornseeding and fertilizing machine and the distance between seed grooves in a seeding disc are adjusted, and the seeding row spacing and the seeding line spacing are within 38-39 cm and are equal to each other; the planting density is about 4400-4600 plants / mu, the mutual shading influence of early-stage plants can be reduced to the maximum extent, so that seedlings are promoted to grow early, and afull dose of seed fertilizer is adopted and applied to the late-sowing corn at a time in the corn seeding process, so that the seedlings are promoted to grow early; and all tassels of the corn are removed. According to the method and the special simple corn detasseling device, shading is reduced, the utilization efficiency of photo-thermal resources is improved, and in addition, nutrient consumption in the later period is reduced.

Description

technical field [0001] The invention belongs to the technical field of a late-sowing summer corn high-yield method and a corn detasseling device, and in particular relates to a late-sow summer corn high-yield method and a special simple corn detasseling device. Background technique [0002] Summer corn and wheat are one of the two major food crops in Hebei Province, which are of great significance to ensuring national food security. Summer corn is a C4 crop, which likes light and temperature, and has great yield potential. The main planting system in Hebei Province is two crops of wheat and corn a year, and the heat conditions are relatively tight. Therefore, early sowing of summer corn has always been emphasized. However, many situations in actual production will cause late sowing of summer maize: for example, over-exploitation of groundwater. In many places, water-saving crops such as potatoes and oil sunflowers are planted in spring to replace wheat that requires a large...

Problems solved by technology

However, many situations in actual production will cause late sowing of summer maize: for example, the treatment of over-exploitation of groundwater. In many places, water-saving crops such as potatoes and oil sunflowers are planted in spring to replace wheat that requires a large amount of irrigation to reduce over-exploitation of groundwater. However, due to heat conditions in Hebei Province , the planting of potatoes and oil sunflowers tends to have a later harvest period than traditional wheat planting, resulting in a later sowing date of the next crop of summer corn; the low plains of Hebei are irrigated with deep wells, and each deep well irrigates an area of ​​more than 200 mu, and the cycle of rotation irrigation is generally 15 days above

Therefore, there are always some summer corns that cannot be sown at the right time and have to be sown late; in addition, there are other reasons such as stubble fall that cause some summer corns to be sown late
