Efficient planting method for intercropping of annual triple-cropping wheat, corn and beans

Abstract

The invention discloses an efficient planting method for intercropping of annual triple-cropping wheat, corn and beans. The planting method includes the steps of land preparation, wherein the land subjected to rotary tillage is prepared into a ridged field the width of which is 160 cm; sowing, wherein a combined sowing machine is adopted for completing sowing of the wheat, beans and corn accordingto a line ratio of 6:1:2 in the ridged field, the bandwidth of the wheat and corn is 80 cm, the line spacing of the wheat is 12 cm, the plant spacing of the wheat is 25-45 cm, the line spacing of thecorn is 40 cm, and the plant spacing of the corn is 25-45 cm; staggeredly planting the beans and the corn in lines between the wheat and the corn, wherein the spacing among the beans, the wheat and the corn is 15 cm, and the plant space of the beans is 25-45 cm. According to the provided efficient planting method for intercropping of the annual triple-cropping wheat, corn and beans, the yield isincreased by 10-40% under comparison with monoculture. By means of the method, the land utilization efficiency is improved, biological fertilizer culture of farmland is also achieved, and the method is an intensive, sustainable and efficient planting method.

Description

Technical field [0001] The invention relates to a method used in the case of crop cultivation. More specifically, the present invention relates to a high-efficiency planting method for intercropping wheat, corn and soybeans with three crops a year in the case of planting wheat, corn and soybeans. Background technique [0002] In order to increase the output value, the existing wheat planting usually uses wheat intercropping with corn. The two crops require roughly the same fertilizer requirements, but because the two require the same fertilizer, but in order to ensure higher yields, the two The distance between them needs to be controlled, which also makes the utilization rate of the land less than required. At the same time, the process of wheat intercropping and corn planting is not conducive to biological fertilization and rational use of the land to increase its yield. At the same time, it cannot be used during planting. Reduce the use of fertilizers. Summary of the inventi...
