稻作杂交技术诸如去雄授粉等问题,常为一般选种家与农业科学工作者所重视,并随时研究改善,期收事半功倍之效。Jodon 氏倡用水稻温水去雄法,在花器不受损伤的情形下举行交配,因此杂交结实率提高,杂交种子结实饱满,杂种第一代成活率高而生长健旺。国内农业科学工作者采用此法甚为普遍。但因去雄时所用方法不适当,稍不注意穗下的茎部因过度弯曲而折 Paddy hybridization techniques such as the removal of pollination and other issues, often for the general election of species and agricultural scientists attach importance to and study at any time to improve, reduce the effect of multiplier. Jodon’s advocate of warm rice to water male method, in the flowers without injury under the circumstances of mating, so the seed setting rate increased, full of hybrid seed full of hybrids, the first generation of high survival rate and growth and prosperity. Domestic agricultural scientists to adopt this method is very common. However, due to the method used to remove the male inappropriate, slightly do not pay attention to the spike under the stem due to excessive bending off
