四川盆地水旱两熟稻田约有2200万亩左右,中稻收后到播(栽)小麦、油菜尚有两个月左右空闲时间和占全年20％左右的温光资源未得到合理利用,是我省农业生产增种增收的一个巨大潜力。稻田新三熟制即是在水旱两熟的基础上,采取合理的作物及品种组合,充分利用水旱两熟制稻田空闲的晚秋资源,增种一季秋作物。其种植方式主要有油稻苕,油(麦)稻菜和麦(油)稻绿肥(饲料)、蔬菜套油菜三种。在不影响正季粮油产量的情况下,增种的秋作物一般每亩可增收红苕1000公斤,鲜苕藤1500公斤左右,或蔬菜1000—2000公斤,或饲料1000—2000公斤,增加产值100—500元。不仅提高了稻田的经济效益和
There are about 22 million mu of paddy fields with floods and droughts in Sichuan Basin. After middle-season rice is sown to sowing (planted) wheat, rape still has about two months of free time and about 20% Agricultural production in our province by planting a huge potential increase. The new three-cropping system in paddy field is based on flood and drought and double cropping. Based on the reasonable combination of crops and breeds, it makes full use of the late late autumn resources in paddy fields with double cropping system, and increases the crop of one season. The main methods of cultivation are rice 苕, oil (wheat) rice and wheat (oil) rice manure (feed), vegetable rape three. Without affecting the production of grain and oil in the normal season, the increase of autumn crops generally per acre can be added 1000 kg of red crab, fresh vine about 1500 kg, or 1000-2000 kg of vegetables, or feed 1000-2000 kg, an increase of output value of 100- 500 yuan. Not only improve the economic benefits of paddy fields and
