近年来,本省各地对稀播壮秧在春花田早稻和连作晚稻上的应用,已进行了较详细的研究,并取得了显著的增产效果。但在绿肥田早稻上的应用却研究较少。由于绿肥田早稻播种育秧期间气温较低,秧苗生长缓慢,当地习惯上秧田播种量往往偏高。如遇低温多雨年份,由于播种量过多而造成大面积烂芽死苗,或秧苗生长瘦弱黄小,最终影响良种面积和产量的降低。本试验是在春花田
In recent years, the province has been carried out a more detailed study on the application of thinning and sowing seedlings to early spring rice and continuous cropping rice in spring and field, and achieved remarkable yield increase. However, the application of green manure early rice has been less studied. Due to the low temperature during planting and transplanting of green manure early rice, the growth of the seedlings is slow, and the seeding rate of the local habit is often high. In case of low temperature and rainy years, due to excessive seeding caused by large-scale rotten buds, or thin yellow seedling growth, the final impact on the reduction of area and yield.
