黑豆叶面积指数及干物质积累与产量的关系

试验以沈农黑豆3号和辽黑1号为试验材料，研究了黑豆在不同施肥水平下的干物质积累动态及叶面积指数与产量的关系。结果表明：各品种在施肥水平下的干物质、叶面积指数及产量均高出对照，叶面积指数与产量的相关性在始花期达显著水平，在结荚期达到极显著水平；干物质与产量的显著相关性出现在结荚期。始花期至结荚期黑豆保持着较高的叶面积指数可以增加相应的干物质积累量、荚数、粒数，选用优良品种辅以高产栽培措施，可以获得较高的产量。

Studies on the Relationship Between Yield and Leaf Area Index and Their Dry Matter Accumulation in Black Soybean

The relationship between yield and leaf area index and their dry matter accumulation were studied by using two black soybean cultivars which have high yield potency,under different fertilizer levels.This experiment showed that: The dry weight,leaf area index and yield of all varieties were higher than CK under fertilizer levels,the correlation coefficients of yield with the leaf area index were tending to positive correlation in before flowering stage and was significant in pod stage;the correlation coeffic...
