摘要
本文研究了川西平原雨养条件下地膜覆盖对水稻的生物学效应。结果表明:覆膜栽培可使水稻提早返青,促进早发多发分蘖,迅速增加叶面积,减缓叶片早衰,增加根系重量,但使水稻齐穗期有所延迟。
Biological effects of plastic film mulching on rice production were studied in the field experiment in rain-fed area in Chuanxi plain.The results showed that the rice growth under plastic film mulching was more exuberant at the early transplanting stage compared with conventional cultivation.The tiller number,leaf area and root biomass of rice under plastic film mulching were higher than that in conventional cultivation,while heading stage was put off for 3 days.And leaf vitality under traditional treatment was premature aging in contrast with plastic film mulching.Therefore,rice plastic film mulching cultivation was an efficient technology.
