1985～1987年我市在进贤县南台、七里、凤岭等乡进行了玉米不同间套作的试验,将传统的麦—豆—芝麻种植方式,改为麦(油)—玉米(大豆、花生、红薯)—芝麻(萝卜)等形式。玉米间作面积由1985年的85.8亩发展到1986年的320亩,1987年由于种子不足面积仅为270亩。在不同间作方式中,玉米以同红薯间作产量最高,一般亩产220公斤左右,其次是与花生间作,亩产77公斤左右,与大豆间作,亩产65公斤左右。大豆、花生、红薯等间作物亩产接近单作产量水平,大豆一般每亩60～75公斤,花生200～225公斤,红薯1000～1200公斤。由于实行了间作,不但可多收获一季玉米,而且可减轻旱情,有利大豆、花生及瓜类作物的生育,提高单产。
From 1985 to 1987, the city experimented with maize intercropping in Nantai, Qili and Fengling counties in Jinxian County, changing the traditional planting method of wheat-bean-sesame into wheat-oil-corn (soybean, Peanut, sweet potato) - sesame (radish) and other forms. The intercropping area of maize increased from 85.8 mu in 1985 to 320 mu in 1986. In 1987, the acreage was only 270 mu due to insufficient seeds. In different intercropping modes, the yield of maize from the same sweet potato is the highest, about 220 kg per mu, followed by intercropping with peanut, about 77 kg per mu and intercropping with soybean, about 65 kg per mu. Soybean, peanuts, sweet potatoes and other inter-crop yields close to single-crop yields, soybean generally 60 to 75 kg per acre, peanuts 200 to 225 kg, sweet potatoes 1000 to 1200 kg. As a result of the intercropping, not only will one more harvest of maize crop be achieved, but also the drought will be alleviated and the growth of crops such as soybean, peanut and melon will be favorable and yield will increase.
