水稻覆膜节水增温高产栽培技术研究
Study on Filming High Yield Cultivation Technique of Rice to Save Water and Increase Temperature
摘要
Abstract
In order to increase the efficient of active accumulated temperature in Heilongjiang province, release the contradiction between paddy field area expansion and limited water resource, the effect of rice growth, tillering dynamic change and yield components were studied by the method filming and irrigation. The result showed that there was improvement function of filming to rice growth, it could shorten growth period, increase soil temperature,decrease leaf chlorophyll content slowly, increase leaf area index by 47.37% and yield by 10.37%. It was a saving water and increasing temperature high yield cultivation technique with obvious effect and easily grasped by farmers.关键词
