大豆行间覆膜栽培技术增产因素分析

Analysis for Yield Increasing Reasons to Inter-row Mulching Cultivation in Soybean

行间覆膜栽培技术对大豆增产效果明显,本文通过试验研究分析了大豆行间覆膜栽培技术增产因素。通过对大豆行间覆膜栽培技术耕层土壤温度、土壤含水量、大豆根系以及大豆植株高度的调查,表明大豆行间覆膜以后,地温升高、土壤含水量增加、大豆植株根瘤数增加、大豆植株的生物量增加,从而促进了大豆产量的增加。

Reasons to increased yield by inter - row mulching cultivation in soybean was analyzed, including the increased soil temperature, soil moisture, nodule number, and biomass.
