Water-saving and high-efficiency planting method of potato millet three times a year

Abstract

The invention relates to a water-saving and high-efficiency planting method for three crops of potato millet a year, which is divided into potato strips A sown in early spring and potato strips B sown in autumn. Potato strip A in early spring is planted together with potatoes and early-maturing millet. Potatoes are sown before and after the start of hibernation. The first batch of potatoes is harvested from the end of May to early June. The first crop of potatoes, the second crop of potatoes is harvested from the end of October to November. Autumn sowing potato strip B is planted together with potatoes and rapeseed. Spring rapeseed is sown in late March as green manure. Potatoes are sown in early and mid-August. Potatoes are harvested from the end of October to early November. Winter rapeseed is sown in furrows in mid-to-late September. In May of the next year, it will be turned over and used as green manure. The invention is planted under water-saving conditions, taking into account crop yield and water-saving ecological benefits, constructs an ecologically harmonious planting mode, increases agricultural product yield, saves groundwater resources, and is beneficial to protecting the natural ecological environment.

Description

technical field [0001] The invention belongs to the technical field of crop production, and relates to a water-saving and yield-increasing production method, in particular to a water-saving and high-efficiency planting method for three crops of potato and millet a year. Background technique [0002] Potato has a short growth cycle, drought tolerance, barren tolerance, high and stable yield, and wide regional adaptability. Millet is resistant to drought and barrenness, has high water use efficiency, and uses less chemical fertilizers and pesticides. It is a typical environment-friendly crop. It only needs 257g of water to produce 1g of dry matter, equivalent to about 1 / 2 of corn. [0003] Due to perennial drought and low rainfall in North China, groundwater resources are scarce, and water for irrigation is in short supply, which affects the high and stable yield of field crops. Potatoes are mostly sown in spring, and millet is mostly sown in summer in Hebei Province. Ridgin...
