光叶紫花苕子

光叶紫花苕子是湖北省烟田的重要绿肥作物。

Vicia villosa Roth var is one of the main green manures in tobacco field in Hubei Province .

烟田翻压光叶紫花苕子做绿肥时，应在烟苗移栽前翻压，并适当减少化肥用量。

When we turned under Vicia villosa Roth var. as green manure in tobacco fields , they should be turned under before tobacco transplanted , and reduced the amount of fertilizer properly .

结果表明，种植烤烟与否对烟田土壤中翻压光叶紫花苕子的有机物质腐解及养分释放动态无明显影响。

Results show that there was no significant influence on organic matter decomposition and nutrient release dynamics of turn Vicia villosa Roth var. in tobacco fields whether it planted flue-cured tobacco or not .

在湖北恩施利用2年大田定位试验研究了光叶紫花苕子不同翻压量对烤烟生长发育、产质量及养分吸收的影响。

A 2 years field experiment was conducted to study the the effect on tobacco development and production quanlity , also about nutrient absorption , researching by different manure application amounts and periods in Enshi city , Hubei province .

获得以下主要结果：1.在田间条件下利用埋设尼龙网袋法研究了光叶紫花苕子做绿肥翻压后的腐解速率及养分释放规律。

The main results were showed as follows : 1 . With the buried nylon bags method a field experiment was carried out in tobacco fields to study dynamics of nutrient release and decomposing rates of Vicia villosa Roth var. as green manure .
