摘要:
研究了栽培和灌溉模式对水稻生长、产量与倒伏性状的影响，以探寻江苏省水稻适宜的节水高产模式。采用桶栽试验，设置移栽稻、直播稻两种栽培模式，以及浅水勤灌、蓄水控灌高蓄、蓄水控灌低蓄3种灌溉模式，分析了水稻生长、产量和倒伏指标对灌溉和栽培模式的响应特征。结果表明，乳熟期前直播稻的株高低于移栽稻，而在黄熟期无显著差异。与移栽稻相比，直播稻植株重心高度和重心比例升高，茎粗减小，抗折力下降，倒伏指数升高（控灌高蓄除外）。控灌低蓄处理能减小节长、增加茎粗，提高茎干抗折力，从而降低茎秆倒伏系数。直播稻产量低于移栽稻。蓄水控灌降低了产量，其中控灌高蓄处理的产量低于低蓄处理，但差异不显著。上述成果对江苏省水稻灌溉和栽培模式选择具有指导意义。
Abstract:
The effects of cultivation and irrigation modes on rice growth yield and lodging traits were studied in order to explore the suitable water-saving and high-yield mode of rice in Jiangsu province. Two cultivation modes of transplanted rice and direct-seeded rice, and three irrigation modes of shallow and frequent irrigation （SFI, CK）, controlled irrigation with high depth of water after rainfall （CH） and controlled irrigation with low depth of water after rainfall （CL） were tested by barrel-planted experiments. The results showed that the plant height of direct-seeded rice was lower than that of transplanted rice before milk ripening stage, but there was no significant difference at yellow ripening stage. Compared with transplanted rice, direct-seeded rice would increase the barycenter height and barycenter ratio of plant, decrease stem diameter and bending resistance , and thus increase lodging index （except for CH）. CL could reduce the stem length, increase the stem diameter, improve the stem bending resistance, and thus reduce the lodging index of stem. The yield of direct-seeded rice was lower than that of transplanted rice. Controlled irrigation reduced the yield, where CH treatment was lower than CL, while the difference between treatments was not significant. The above results will be useful for rice irrigation and cultivation pattern selection in Jiangsu Province.
