大豆不同垄向栽培增产效果研究初探

为了探明不同垄向方位对大豆产量的影响,通过对东-西垄向、南-北垄向、西南-东北垄向、东南-西北垄向耕作条件下大豆的叶面积指数、干物质积累、叶绿素含量、产量及产量性状进行研究。结果表明：大豆不同垄向栽培叶面积指数花期各处理均在7.0以上,结荚期西南—东北垄向的叶面积指数最高为6.52,干物质积累花期时西南—东北垄向最高为18.38g,结荚期西南—东北垄向最高为30.98g,叶绿素含量变化差异不明显,西南—东北垄向的产量最高为2746.0kg/hm2,较其他垄向平均增产22.51kg/hm2。从试验结果可以看出,西南—东北垄向栽培方式对大豆高产的获得具有重要研究意义。

The Research Discussed on Effect Increasing Yield of Soybean with Different Ridges Cultivation

To explore the impact of soybean yield on different orientation of the ridge ,the leaf area index,dry matter accumulation,the content of chlorophyll the yield and its characters of soybean with different ridges cultivation were tested,the result showed that： The size of leaf area index were in 7.0 above ,in the podding period southwest to northeast ridges the highest was 6.52,dry matter accumulation was highest 18.38 g of northeast to southwest ridges in flowering period,and 30.98 g of southwest to northeast ridges in podding period,the content of chlorophyll change still performance highest for the northeast to southwest ,the highest hectares yield were 2746.0 kilograms of Northeast to southwest ridges ,compared with other ridges average yield increased 22.51 kilograms.
