[目的]探明节水稻新品种“绿旱1号”的水分利用率,为其进一步示范推广提供参考依据。[方法]对节水稻新品种“绿旱1号”与原始受体6527进行全生育期无水层旱处理,以正常灌溉为对照。[结果]在较正常灌溉节水67.4%的条件下,“绿旱1号”千粒重、结实率、株高、有效穗降幅较小,且均未达显著水平,而原受体“6527”小区产量、穗总粒数、理论产量、穗实粒数降幅均超过25%,且均达极显著水平(P<0.01)。[结论]“绿旱1号”在节水栽培条件下,表现出产量稳定、节约能源、减少环境污染等优点。
[Objective] The research aimed to find out the water use efficiency of a new rice variety “Lvhan No.1” which is a water-saving rice and provide a reference for further demonstration and popularization. [Method] The new paddy rice variety “Lvhan No.1” and original recipient “6527” were treated with the waterless layer drought treatment during the whole growing period, which was controlled by normal irrigation. [Result] Under the condition of 67.4% water saving compared with normal irrigation, the grain weight, seed setting rate, plant height and effective panicle of “Green Dry No.1” were less and did not reach significant level, while the original “ The area yield, the total number of grains per ear, the theoretical yield and the number of spike grains exceeded 25%, all of which reached the extremely significant level (P <0.01). [Conclusion] ”Green Drought 1" showed the advantages of stable yield, energy conservation and environmental pollution reduction under water-saving cultivation conditions.
