Embodiment 1

[0009] a Crop rotation Under dry land conditions, the sequence of crop rotation is wheat, soybean, rape, sunflower, buckwheat, and wheat is planted after buckwheat; under irrigation conditions, the sequence of crop rotation is wheat, soybean, corn, sorghum, millet, and millet is planted after wheat. Once a year, the scientific rotation of these diverse crop types (including cereals and broadleaf crops, warm-season crops and cool-season crops) will greatly help weed control.

[0010] b Weed control before sowing 7-10 days before sowing, use 30% Feida soluble powder or 41% Nongda water agent, the average dosage is 120-200g / mu, mixed with clean water 30-40kg / mu, and spray to kill weeds.

[0011] c Spring no-tillage sowing with 200Z4 / 8 precision rotary seeder sowing, supporting power 60-654 tractors. The soil bulk density of loam in the 0-5cm plow layer is less than 1.2g / cm 3 , clay soil bulk density is less than 1.4g / cm 3 , The soil moisture content in the 0-10cm plow layer mu...

Abstract

The invention discloses a ruderal control method for protection cornfield in farming-pasturing interlocked areas, which is characterized in that: the method is the ruderal combination control method for cornfield combining the chemical weed control, weeding by machine, weeding by manpower and other methods for weeding based on agricultural wheels. The method reduces the water erosion and wind erosion about 30 per cent for soil and vaporization of water in soil, enhances soil infiltration capacity, improves the rainwater utilization rate, increases the organic content on surface of the soil and lowers the operation cost by 20 to 50 per cent; besides, the invention can reduce the surface runoff by 50 to 60 per cent and soil lose about 80 per cent and enhance soil storage capacity of 16 to 19 per cent, thus deducing the smoke and protecting the environment.

Description

technical field [0001] The present invention relates to a method for controlling weeds in wheat fields used in protective farming in interlaced areas of agriculture and animal husbandry, in particular to a method for controlling weeds in wheat fields based on agricultural rotation and combined use of chemical weeding, mechanical weeding, artificial weeding and other weeding methods . Background technique [0002] my country's agriculture-pastoral ecotone is a zone where the farming industry and the animal husbandry industry meet. The quality of the ecological environment in this zone directly affects the quality of the ecological environment in northern my country. There are not only agriculture and animal husbandry, but also seasonal farming and seasonal animal husbandry. This is the most unstable area of ​​agricultural and animal husbandry production methods. The degradation of cultivated land and grassland is manifested in five aspects: severe wind erosion and desertific...
