Abstract

The invention discloses a method for storing moisture and preventing drought in a dry farming spring corn area. According to the method, after autumn crops are harvested, fertilizer applying, deep tillage, rake grinding and applying of chemical herbicide are performed in the late autumn and early winter according to the requirements for sowing plastic-film corn in spring of the next year, a plastic film is timely covered, hole sowing is directly performed on the film during sowing in spring of the next year, and harvest is performed in autumn. The method has the benefits as follows: by means of the provided method for storing moisture and preventing drought in the dry farming spring corn area, the water and moisture storing capacity can be enhanced, the soil moisture environment is improved, sowing in the optimum period and full stand of corn are guaranteed, the stress resistance of corn is enhanced, and the corn yield and the water use efficiency are improved. With the application of the method, the capacity of dry farming spring corn in the north of China in adapting to drying and warming of climate is improved, and the method has a very important significance in stable increase production and high yield of the corn in the dry land.

Description

technical field

[0001] The invention relates to the technical field of crop cultivation methods, in particular to a method for storing moisture and resisting drought in a dry-farmed spring corn area. Background technique

[0002] Natural precipitation is the only water resource available for agricultural production in dryland areas in northern my country. However, the total amount of precipitation is insufficient and the distribution of time and space is uneven. The precipitation period is misaligned with the crop water demand period. % of the precipitation is lost in the form of surface runoff and ineffective evaporation, resulting in long-term low and unstable crop yields, and it is difficult to sow and preserve seedlings of spring sowing corn. Therefore, high-efficiency precipitation storage and drought prevention is a long-term strategy and a major technical demand.

[0003] Climate warming has aggravated the occurrence and damage of drought, and the technology of soil...
