Efficient planting method for intercropping semen coicis and early-maturing soybeans

Abstract

The invention discloses an efficient planting method for intercropping semen coicis and early-maturing soybeans. According to the efficient planting method, the semen coicis and the soybeans are intercropped, so that cropping index, yield and income all can be increased in the manner of utilizing the empty land space in time difference and space difference in the early growth period of the semen coicis to intercrop a batch of soybean; the rhizobium of the soybeans can be fully utilized to fix nitrogen and increase nitrogen, and the available nutrients of soil can be added and supplied to the semen coicis after the soybean leaves are buried for improving and fertilizing the soil; on the basis of the characteristics of short symbiotic stage and high complementation of ecological benefits of the semen coicis and the soybeans, the maximal benefit of the land can be acquired; according to the method, the traditional mode of singly planting the semen coicis is broken through; the high and short crops are intercropped in a strip form, so that a height difference is formed, the growing season and the microclimate condition are fully utilized, the soil fertility, space and optical energy are reasonably utilized and the cropping index is increased; according to the efficient planting method, the yield of the semen coicis is more than or equal to the yield of singly planted semen coicis, 0.4 hectare of soybeans per hectare are additionally harvested and the purpose of increasing yield and income of the farmer is achieved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a high-efficiency planting method of coix coix intercropping early-maturing soybeans. Background technique [0002] Job's tears (Coix lachryrma-jobi L.) has been a food with the same source of medicine and food since ancient times. The seeds are used as medicine, which has the functions of invigorating the spleen and removing dampness, eliminating numbness and stopping diarrhea, clearing away heat and expulsing pus.
