安徽省安庆地区农科所,三年来进行稻田油肥大窝间作栽培试验示范,试验结果,油菜亩产300斤,箭舌豌豆鲜草亩产1,500斤。油稻稻平均亩产1,932斤,比肥稻稻增产18.2%,土壤有机质由2.72%提高到2.96%,而肥稻稻由2.72%下降到1.98%。油菜绿肥大窝间作,其增产原因在于提高光合有效辐射利用率,改善二氧化碳的供应条件,提高二碳酸核酮糖羧化酶的活性,促使油菜冬前
Anqing Agricultural Science Institute in Anhui Province, three years of rice paddy intercropping cultivation experiment demonstration, the test results, rape per mu yield 300 pounds, tongue pea fresh grass per mu 1,500 pounds. The average yield of rice was 1,932 kg, 18.2% more than that of paddy rice, 2.72% of soil organic matter and 2.96% of that of paddy rice, while the decrease of paddy rice from 2.72% to 1.98%. The reason for the increased production of rapeseed green mantel is that the utilization of photosynthetically active radiation is improved, the supply conditions of carbon dioxide are improved, the activity of ribulose carboxylase of bicarbonate is increased,
