滨海稻区旱直播条件下水稻品种的适应性研究

Study on the Adaptability of Rice Varieties under Dry Direct Seeding in Coastal Region

基于为直播稻将来在滨海稻区迅速发展给予品种支撑,以吉粳系列、铁粳系列、北粳系列、盐粳系列等27个水稻品种为材料,对各品种在滨海稻区旱直播条件下的成苗率、耐盐能力、收割前能否完全成熟等情况进行试验分析,结合田间表现及小区实割测产,确定滨海稻区适宜旱直播的粳稻品种。结果表明,旱直播条件下盐粳933、盐粳1403、盐粳927、盐粳662、盐粳765、盐粳22、富友33、北粳1604、铁粳14、吉粳88等品种的成苗率高、耐盐能力强、收割前能完全成熟,平均产量为8.03t/hm2,适宜在滨海稻区作旱直播稻推广。

Based on the rapid development of direct seeding rice in coastal area, 27 rice varieties contains Jigeng Series, Tiegeng Series, Beigeng Series and Yangeng Series, were used to analyze the seedling rate, salt tolerance and maturity of each variety under dry direct seeding condition. According to the field performance and yield to choose the suitable varieties for dry direct seeding in coastal areas. The results showed that Yangeng 933, Yangeng 1403, Yangeng 927, Yangeng 662, Yangeng 765, Yangeng 22, Fuyou 33, Beigeng 1604, Tiegeng 14 and Jigeng 88 had high seedling rate, strong salt tolerance and good maturity, the average yield was 8.03 t/hm2, which were suitable for planting as dry direct seeding rice in coastal areas.
