摘    要:通过对水稻旱作覆膜增温保墒效果的系统研究,表明水稻旱作覆膜具有显著的增温效果和较好的保墒作用。由于覆膜的增温保墒作用,旱作覆膜后的前期生长比不覆膜旱作、水作旺盛,分蘖盛期来得早,使水稻旱作覆膜比不覆膜有显著的增产效果

关 键 词:水稻旱作  覆膜  增温保墒效果  生育性状影响

Abstract:The effects of plastic film mulching on temperature increase and preservation of soil moisture were studied in rice field under dry land cultivation. The results show that the soil temperature was markedly raised and the soil moisture kept high by means of plastic film mulching. The tillering at early stage was more exuberant than that under dry land cultivation without plastic film mulching and wetland cultivation, and the exuberant period of tillering was more earlier. The rice yield under dry land cultivation with plastic film mulching was higher than that without plastic film mulching, which increased by 48 1%~108 9%.
Keywords:rice under dry  land cultivation  plastic film mulching  temperature increase and soil moisture preser  vation  rice growth character
