Embodiment 1

[0048] (a) Site selection: Choose a flat land without miscellaneous stones, the slope is required to be less than 10°, and the diameter of miscellaneous stones is less than 5cm. Do not choose tuyere, green sand exposed, low fertility, barren land.

[0049] (b) Plowing and harrowing: Use a rotary plow to plow the selected land, with a root depth of not less than 30cm. After plowing, harrow the field to break up large soil clods. The diameter of the soil clods is required to be less than 5cm. .

[0050] (c) Applying organic fertilizer: Sprinkle decomposed farmyard manure on the plot after plowing, and the amount of farmyard manure spreading is determined according to soil fertility.

[0051] (d) Soil preparation: further rake and fine-grain land preparation on the plot after spreading farmyard manure. It is required that the land surface should be flat without large clods of soil and farmyard manure, and the diameter of the piece should be less than 3cm.

Abstract

The invention discloses a technology for controlling and eliminating weeds in an alfalfa field by film-side planting. According to the technology, the coverage of the weeds in the alfalfa field can be effectively controlled, and can be reduced by 21 to 46 percent; in addition, the annual yield of alfalfa hay is greatly increased by 19.8 to 152.6 percent; total yield per hectare in three years is increased by 9,387.6 to 9,438.4kg, and if per ton of alfalfa hay is 2,400, economic benefits per hectare can be increased by 22,530 to 22,652 yuan, and efficiency per hectare is equivalently improved by 1,502 to 1,510 yuan; moreover, the using amount of a weed killer is reduced, pollution to the environment is reduced, and the target of low-environmental consumption production of the alfalfa industry can be effectively promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural production, in particular to a technology for controlling weeds in the alfalfa field through a film side planting method. Background technique [0002] As people pay more and more attention to food safety, the call for the healthy development of animal husbandry is gradually rising, especially after the melamine and clenbuterol incidents, people attach great importance to the quality of high-quality meat products and dairy products. In order to better promote the healthy and sustainable development of the dairy industry, the No. 1 Central Document of the Twelfth Five-Year Plan proposed the "Alfalfa Development Action for the Revitalization of the Dairy Industry", which set off a climax of alfalfa planting across the country, and the alfalfa planting area expanded year by year. case, alfalfa is grown as follows: [0003] (1) Site selection: Select plots with deep soil, loose soil, and not eas...
