Corn early-sowing method in cold region humid area

Abstract

The invention belongs to the technical field of corn cultivation, and provides a corn early-sowing method in a cold region humid area. The corn early-sowing method in the cold region humid area is provided to solve the problems of a traditional corn sowing method in the humid area of the Heilongjiang, performs sowing in advance, improves the utilization efficiency of photo-thermal resources in climate resources and the utilization rate of soil moisture by corn and achieves high quality and high yield of the corn. According to the method, 5 cm ground temperature stably passes through 5 DEG C for 5 days continuously to serve as the initial sowing period, and the key technologies to be matched comprise autumn soil preparation, fertilization, seed selection, seed coating, ditching during sowing, intertillage and reasonable close planting. By demonstrating, popularizing and applying the early-sowing method, the improvement of the scientific farming level of a farm is promoted, and the development of local economy is promoted.

Description

technical field

[0001] The invention belongs to the technical field of corn cultivation, and in particular relates to a method for early sowing of corn in cold and humid regions. Background technique

[0002] Due to the unique natural environment in the humid area of ​​Heilongjiang, using the traditional corn sowing method, that is, the ground temperature of 5cm stably passes through 8 degrees for 3 consecutive days, sowing spring corn will delay the sowing time, reduce the utilization rate of light and heat resources, and delay the maturity of corn , the dehydration rate of the kernel is slower, which eventually leads to lower corn yield and lower quality.

[0003] At present, in the production process of spring corn in the humid area of ​​Heilongjiang, there are key problems such as outstanding soil plow layer quality, low temperature and humidity, frequent occurrence of chilling damage and waterlogging, single corn variety, low yield of grain machine, and low utilization ...

Embodiment 1

[0026] In 2020, Station 2 of the Seventh Management District of Bawuer Farm, Baoqing County, Heilongjiang Province used the sowing method and supporting technology of the present invention. After applying the same amount of fertilizer, the yield of the "three-five" sowing method was 916.3 kg / mu (grain moisture content 29.73%); traditional sowing (5cm ground temperature stably passed 8 degrees for 3 consecutive days) yield was 861.09 kg / mu (grain moisture content 32.33%). The corn variety is Demeiya No. 3.

[0029]In 2020, at 5 stations in the third management area of ​​852 Farm, the "three-five" sowing method and supporting technologies were used. After applying the same amount of fertilizer, the yield of the "three-five" sowing method was 875.16 kg / mu (the moisture content of the grain was 32.63 %); traditional sowing (5cm ground temperature stably passing through 8 degrees for 3 consecutive days) yield is 813.38 kg / mu (grain moisture content is 33.17%). The corn variety is Huanong No.1.
