小流量与大流量滴灌带对大豆生长及产量的影响

摘要

The four main physiology traits of soybean had been analyzed and evaluated comprehensivly under the cuhivation pattern of one film and one pipe with four line by using small aperture drip tape （12-1.6 L/h） and large aperture drip tape（ 16-2.8 L/h）. The results showed that plant dry material accumulation, leaf area index（LAI）, population photosynthetic potential and soybean yield of large aperture drip tape（ 16-2.8 L/h） were all higher than that of small aperture drip tape （12-1.6 L/h）.%本研究在一膜一管四行大豆膜下滴灌的栽培模式下采用小管径小流量 12—1．6L／h滴灌带与常规大管径大流量 16—2．8L／h滴灌带对膜下滴灌大豆进行了4个主要性状指标的综合分析和评价。结果表明，16—2．8L／h滴灌带在干物质积累、叶面积指数、群体光合势、产量等方面均高于 12—1．6L／h滴灌带。
