河北省景县的实践证明,油菜和夏播棉一体化种植,是低产田当年变成高效益农田的良好途径。该县从1986年开始小面积试种油菜,并探索油菜夏播棉一体化栽培,取得了较高的经济效益。方法是8月底前后在棉田内破皮撒播油菜,来年5月20日左右油菜收获后,立即翻耕整地播种夏棉。一般亩产油菜籽150—250公斤,每100公斤油菜籽可出食用油40公斤、菜籽饼50多公斤,亩收入300—500元。夏播棉亩产皮棉一般在50—65公斤,亩收入350—500元。全年两茬亩效益可达650—1000元,比一季春播棉高200—300元,比小麦、夏播棉一体
The practice in Jingxian County, Hebei Province, proved that the integrated rapeseed and summer sowing cotton cultivation is a good way to turn low-yielding fields into high-efficiency farmland that year. Since 1986, the county began to test rapeseed on a small area, and explored integrated cultivation of summer rapeseed and rapeseed and achieved high economic benefits. Method is before and after the end of August in the cotton field rape sowing rape, May 20 next year after about rape harvest, sowing soil preparation sowing immediately. General rapeseed 150-250 kilograms per 100 kilograms of rapeseed can eat 40 kilograms of oil, rapeseed cake more than 50 kilograms, mu income 300-500 yuan. Summer cotton crop cotton lint generally 50-65 kg, mu income 350-500 yuan. The annual benefits of two stubble acres up to 650-1000 yuan, 200-300 yuan higher than the spring quarter cotton, cotton than the summer broadcast
