燕麦与毛苕子混播试验初报

Initial report of sowing mixed oat and hairy vetch trial

各样本苕子蜜均有一定的抗氧化活性，呈现量效关系。

All the honey samples exhibited some antioxidant activity in a dose-dependent manner .

3个苕子品种各生育期无明显差异。

But there was no significant difference among three varieties of Vicia villosa Roth * 3 .

毛叶苕子和箭筈豌豆养分含量和养分累积量的变化趋势与光叶苕子基本一致。

The nutrients content and accumulation trends of Villous vetch and Common vetch were same to Smooth vetch .

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 .

通过对毛苕子进行不同刈割时间与次数对比，发现其生产能力有很大差别。

Compared different cutting time and different cutting frequency , the productivity of hairy vetch has great difference .

施用有机肥增加了土壤的速效钾含量（猪粪例外），施用油枯、猪粪及苕子还显著增加了土壤速效磷含量。

Organic manure increased the soil available K ( except pig dung ) and soil available P significantly .

某些生物因子对苕子根瘤菌菌剂和土著根瘤菌竞争结瘤的影响

Influence of some biological factors on the competition of nodulation of Vetch between inoculants and indigenous strains of Rhizobia

地上部氮、磷、钾、碳素累积量均表现为光叶苕子单作的最低。

The N , P , K , C accumulation of Smooth vetch monoculture in shoots was characterized as minimum .

即使是效益最低的黑麦草+苕子高丹草系统，净收入也分别达到水稻油菜系统的2.09倍，水稻黑麦草系统的1.22倍。

The net income of RVS system was the lowest , but it is still as much as rice-rape system , and 1,22 times of rice-ryegrass system .

除苕子处理上部叶钾氯比小于4，其余均大于4。

In addition K-Cl ratio was less than 4 in the upper leaves in common vetch treatment , and in the rest it was more than 4 .

本次实验时间是1998年5月至1999年4月，实验用种为光叶紫苕（简称苕子）种子。

The experiment was conducted between May , 1998 and April 1999 , with bare milk vetch ( common vetch in short ) seeds as the subject seeds .

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 .

但是，施用油枯、猪粪、秸秆、苕子及无机肥对土壤容重无显著影响，土壤容重变化于1.2698-1.3748g/cm3之间。

However , the soil bulk density was not significantly affected by the application of rapeseed cake , pig dung , straw , common vetch and chemic fertilizer , it varied between 1.2698-1.3748g / cm3.2 .

本文探讨了苕子、柽麻、稻草和锯木屑四种植物残体，在南宁地区赤红土中的腐殖化系数和土壤有机质的自然增减率。

The humification coefficients of plant residues of common vetch , sunnhemp , rice straw and sawdust in lateritic red loam in Nanning prefecture , and the natural increase and decrease rates of soil organic matter were investigated .

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 .

主要试验结果如下：1.与原始土壤相比，定位施用有机肥和无机肥后，明显提高土壤中有机质含量，尤以施用秸秆和苕子的处理最为明显。

Following are the main results : 1 . After the organic manure and chemical fertilizer application , the soil organic matter content showed a remarkable increase , especially straw and common vetch treatments had the most obvious effects .

在旱作处理下，毛叶苕子的累积释放率高于紫云英：四种绿肥均是淹水较旱作条件更利于养分释放。

In drought condition , the cumulative release amount and the cumulative release rate of Villous vetch are higher than Chinese milk vetch . The submerged condition is more conducive to the release rates of the nutrients than the drought condition .

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 .
