我区的粮食生产以双季稻为主,常年水稻的早晚复播面积有130多万亩,中稻面积也有60万亩左右。历年早稻有机肥源,主要靠种植紫云英绿肥解决。60年代中期到80年代中期,我区紫云英绿肥的种植面积,曾多年稳定在100万亩左右,但亩产鲜草徘徊在1500～2000kg的水平上。约有半数田块,种一亩只能自肥一亩;有半数田块种一亩可肥1.5～2亩(含本田,下同)。自从农村推行生产责任制,大力发展越冬经济作物以来,各地在近年已逐步形成了

The grain production in our region is dominated by double cropping rice, which covers an area of ​​more than 1.3 million mu in the morning and in the evening, and the area of ​​medium rice is also about 600,000 mu. Over the years, early rice organic fertilizer source, mainly rely on planting Ziyun Ying green manure. From the mid-1960s to the mid-1980s, the planting area of ​​ShiYunYing green manures in our district has been stable at around 1 million mu for many years. However, fresh grass per mu hovers at the level of 1500-2000 kg. About half of the plots, only one acre of self-fertilizing acre; half of the acre planted acres of 1.5 to 2 acres (including Honda, the same below). Since the implementation of the responsibility system for production in rural areas and the vigorous development of winter cash crops, various places have been gradually formed in recent years
