Mulching film covering planting method for interplanting spring sowing peanuts by using winter wheat

Abstract

The invention discloses a mulching film covering planting method for interplanting spring sowing peanuts by using winter wheat. The method comprises the steps that when the winter wheat is sowed, a peanut interplanting ridge is built, a drip irrigation tape is laid in the center of the ridge, film covering is conducted in the center of the ridge, a winter wheat tape is sowed in the ridge, and thenpeanuts are interplanted on the ridge in the next spring. According to the mulching film covering planting method, through a mode that mulching film covering is conducted on the reserved peanut interplanting row on the ridge in advance, two aspects of effects of film covering and preservation of soil moisture, and rainwater collection on the ridge surface are achieved on wheat growth in the ridge, then the irrigation mode of drip irrigation under covered film is combined, and the irrigation water is greatly reduced; in the peanut season, the effects of warming and preservation of soil moisture, and water saving and irrigation of the mulching film on the peanut growth are further promoted, and the method helps to increase the yield and save water. According to the established water-savingplanting mode, the irrigation water amount can be greatly lowered, the water use efficiency is remarkably improved, the yield of wheat and peanuts can be increased, and the method has the positive popularization significance.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a film-covered planting method for interplanting winter wheat with spring sown peanuts. Background technique [0002] my country is a country with severe drought and water shortage. The total amount of fresh water resources accounts for 6% of the global water resources, and the per capita water resources are only 1 / 4 of the world average level. It is one of the countries with the poorest per capita water resources in the world. The spatial distribution of resources is extremely uneven, and water resources are particularly scarce in northern regions. Low water use efficiency and serious waste of water resources have caused a series of ecological and environmental problems such as serious overexploitation of groundwater, drop in groundwater level, and subsidence of foundations. [0003] Winter wheat, as one of the main food crops grown in northern my country, is a crop that re...

Problems solved by technology

In order to save irrigation water and increase crop yield, spring sowing peanuts can be interplanted between rows before winter wheat is harvested. The traditional large ridge and wide wheat interplanting peanut planting mode is to reserve wide peanut interplanting rows when winter wheat is planted. The interplanting of peanuts in the second half of the year can be done in the open field interplanting mode or in the film-mulched interplanting mode. The film-mulched interplanting can play a role in increasing temperature and moisture in the peanut season, saving water and increasing production to a certain extent, but there is still a problem in the wheat growing season. A large amount of ineffective evaporation and waste loss of soil moisture, resulting in low water use efficiency and insignificant water-saving effects
