摘　　要：为促进水稻节水抗旱高产栽培模式的推广应用,以黑龙江省各积温带水稻主栽品种(系)为材料,通过常规灌溉和节水抗旱两种栽培模式,分析了其对水稻品种(系)的穗部性状和产量的影响。结果表明:节水抗旱处理使各积温带部分品种(系)的穗长变短,穴穗数减少,充实率增加,着粒密度和经济系数增加,同时增加了部分品种(系)的受精颖花率和千粒重,从而使其产量有所提高。筛选出了不同积温带节水抗旱处理后增加产量的品种(系),供当地生产应用参考。In order to promote the popularization and application of water-saving,drought resistant and high-yield cultivation mode of rice,the main rice varieties(lines)of each accumulated temperature in Heilongjiang Province were used as materials,the effects of panicle traits and yield on rice varieties(lines)were analyzed by conventional irrigation and water-saving and drought-resistant cultivation models.The results showed that the water-saving and drought-resistant treatment shortened the ear length of some varieties(lines)of the each accumulated temperature zone,reduced the number of ear spikes,increased the filling rate,increased the grain density and economic coefficient,and increased the fertilization of some varieties(lines).The flower rate and 1000-grain weight increase the yield.The varieties(lines)with increased yield after different water-saving and drought-resistant treatments were screened for local production and application.
