Embodiment 1
[0016] Embodiment 1 of the present invention: an efficient planting method of coix coix intercropping early-maturing soybeans,
[0017] 1) Site selection
[0018] It should be planted in sunny, uniform fertility, loose texture, and convenient drainage and irrigation. The previous crops are suitable for leguminous, cruciferous and root crops. The ambient air quality in the planting area should meet the requirements of GB 3095, the water quality of farmland irrigation should meet the requirements of GB5084, and the soil environmental quality should meet the requirements of GB 15618.
[0019] 2) Variety selection
[0020] Coix varieties are selected from all the Coix varieties suitable for local planting.
[0021] Soybean varieties should choose high-quality soybean varieties with great potential for increasing yield, good plant type, strong resistance, and good internal and external quality. Since they are intercropped with high-stem crops of Job's tears, they should also be ...
Embodiment 2
[0061] Example 2 of the present invention: high-efficiency planting method of coix coix intercropping early-maturing soybeans, the remaining steps are the same as in example 1, but in step 3), that is, two rows of coix coix intercropping and three rows of soybeans are planted in strips, coix coix and coix coix are planted in wide and narrow rows The row spacing is 40-140cm, soybeans are intercropped in wide rows, the row spacing between coix and soybean is 40cm, the row spacing between soybean and soybean is 30cm, the hole spacing of coix is 20cm, 3 seedlings are kept in each hole, and the soybean spacing is 8-10cm. The planting density of coix coix is 11116 plants / 667m2, and the planting density of soybean is 10000-13000 plants / 667m2 2 .
[0062] The key technical features of the field layout compared with the conventional ones: (1) Expand the row spacing between Coix and soybeans; (2) Reduce the narrow row spacing between Coix and soybeans; (3) Reduce the row spacing bet...

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. In addition to its unique medicinal value, it also has high nutritional value, ranking first among grasses, and has the reputation of "the king of grasses in the world". Coix plants are mainly distributed in Southeast Asia, and my country is one of the important origins of Coix in the world. Job's tears are widely planted in the north and south provinces and regions, and are cultivated in areas with an altitude of 35-2500m. Except for Qinghai, Gansu, and Ningx...
