| 摘 要： | 本文研究了川西平原雨养条件下地膜覆盖对水稻产量及其构成因素的影响.结果表明:覆膜栽培可增加水稻的穗长、一次技梗数、单穴穗数、穗着粒数和穗实粒数,但对千粒重的影响不明显;在雨养条件下,所有覆膜处理的水稻产量和单茎干物重均比对照高,覆膜处理对经济系数影响较小;除移栽密度较低的半覆膜处理6外,所有覆膜处理的综合经济效益均比对照高.

| Abstract: | In this paper,the effect of plastic film mulching cultivation on rice yield and yield components were studied in the field experiment under rain-fed area of Chuanxi plain.The results showed that the effect of plastic film mulching cultivation on the ear length,panicles per plant,spikelets per panicles,filled grains and seed-setting rate was significant compared with conventional cultivation,but 1000-grain weight was not obvious under the different cultivations.The rice yield and biomass per plant under plas... |
