A kind of production method of green-fed corn in two-cropping area under pressure mining

Abstract

The invention relates to a method for producing forage maize in an underground water overexploitation restraining two-cropping region, and belongs to the technical field of agriculture. The productionmethod includes adopts a one-year-one-season forage maize planting mode or a white wheat-forage maize two-cropping planting mode, can lower the underground water overexploitation demand of high waterconsumption of white wheat to the greatest extent, can lower the demand for maize seeds, can utilize the advantages of the forage maize as fodder to sow the maize seeds before a rainy season is coming, can preferably water the maize with desalted pool water in a drought season, can ensure the high rate of emergence, can fully allow the forage maize to grow up in heavy rainfall months, can use thedesalted pool water to water the forage maize in the drought season, can determine the harvesting period according to the factors such as illumination, the accumulated temperature, the milk-filling degree, and the ensiling condition, can ensure the maximum benefit of forage maize planting, and can achieve dual objectives of benefits of the forage maize and water conservation.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a production method of green-fed corn in a pressure-harvested double-cropping area. Background technique [0002] The Hebei Plain area is the main grain producing area in Hebei Province, and it is also an area severely lacking in water resources. The area of ​​cultivated land in this area is about 63 million mu, accounting for nearly 71% of the province's cultivated land area, and its grain output accounts for 92% of the province's total. Summer corn Rain and heat are in the same season, but due to the shortage of light and heat resources, the coincidence between rainfall and crop water demand is poor. Under pure rainfed conditions, the yield of corn kernels is unstable. The contradiction between water and food in this area is sharp, the per capita water resources are only 191 cubic meters, the water resources per mu of cultivated land are only 114 cubic meters, t...
