Triple-cropping, water-saving and efficient planting method of potatoes and millet

Abstract

The invention relates to a triple-cropping, water-saving and efficient planting method of potatoes and millet. An early spring potato planting belt A and an autumn potato planting belt B are included,wherein the early spring potato planting belt A is used for matched planting of potatoes and early-maturing millet, potatoes are planted before and after the Waking of Insects, a first crop of potatoes are harvested at the end of May to the beginning of June, rotary tillage and soil preparation are performed while there is enough moisture in the soil, millets are sowed in the first ten days of June, a second crop of potatoes are planted when the millet gets manure in the first ten days of August, and the second crop of potatoes are harvested at the end of October to November. The autumn potato planting belt B is used for matched planting of potatoes and oilseed rape, spring oilseed rape is sowed in the last ten days of March, the oilseed rape is turned over to serve as green manure, the potatoes are sowed in the middle ten days of August, the potatoes are harvested at the end of October to the beginning of November, and winter oilseed rape is sowed in furrows in the mid-to-late September and turned over in the next May to serve as green manure. Planting is performed under the water-saving condition, the output and the water-saving ecological benefits of crops are combined, the ecologically harmonious planting mode is constructed, the yield of agricultural products is increased, underground water resources are saved, and the natural ecological environment is favorably protected.

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...
