Spatial mixed intercrops of rapeseed field
Rapeseed were multifariously intercropped with potato, green cabbage Aikangqing (Brassica rapa), radish- Duanye 13 Yanghua , coriander, spinach, garlic stems, watermelon, etc. on outskirts of city in middle and lower reaches of the Yangtze River. Results of field experiments showed that the models of mixed intercrops of rapeseed-potato-radish and rapeseed-garlic stems-radish were considered as most appropriate one for outskirts of city. Compared with mono-crop pattern, the yield of both rapeseed and interropped crops didn't lost significantly when intercropped with 2-3 other crops in rapeseed field with a plant density of 60000/hm2. And as a spatial mixed intercropping pattern, it could reduce disease incidence by 20 ％ for rapeseed and by 40％ for other crops in average. The production value of this model was obtained more thanl05000 yuan/hm2 per year as intercropped with four or five other crops, which notably exceeds the production value about 27960 yuan/hm2 of traditional planting model of rape-rice-rice. Generalization of spatial mixed intercrops can effectively improve the income of farmers, and promote the rapeseed production eventually.
