豆类萌发期矿物质元素和糖类含量变化的研究

在绿豆(PhaseolusradiatusL)、大豆[Glycinemax(L)Merr]和黑豆(GlycinesojaSieb.etZucc)的萌发期,研究其矿物质元素和糖类含量的变化规律。结果表明:①3种豆类的矿物质元素含量大多数呈一定的规律性变化。②3种豆类的总糖含量随芽的增长而普遍降低,大豆芽超过4.5cm时,其含量有所增加。还原糖含量随芽的增长而普遍升高。黑豆芽萌发到4.5cm时,还原糖含量达最大值(2.35g·kg-1);大豆芽萌发到4.5cm时,还原糖含量达最大值(2.05g·kg-1);绿豆芽萌发到1.5cm时,还原糖含量达最大值(1.50g·kg-1)。     

温室茄果类蔬菜枯萎病的发生及防治

枯萎病是瓜类和茄果类蔬菜的重要病害，此病主要为害番茄、黄瓜、西瓜、苦瓜、冬瓜、甜椒、茄子以及豆类等多种蔬菜。近年来为害呈逐渐加重趋势。据调查，枯萎病一般发病率为5％～25％。导致减产10％～30％，给蔬菜生产带来较大的威胁。     

太行山区豆类作物常见病害的防治

1 锈病 1.1 发生.锈病是真菌性病害.以菜豆、豇豆、蚕豆、大豆受害为重.受害部位以叶为主,叶柄、茎蔓及荚果亦可受害.初生黄白色稍突起的小斑点,扩大后呈黄褐色的夏孢子堆,表皮破裂,散出锈褐色粉末,后期锈粉转黑粉.诱发锈病的主要因素是高温高湿.     

旱地麦后复种玉类糜子荞麦后效观察

通过３ａ旱地麦后复种不同作物后效观察试验结果表明，麦后复种豆类与不复种处理相比，土壤有机质增加０．８３～１．２２ｇ／ｋｇ，全氮增加０．１２～０．１６ｇ／ｋｇ，速效磷增加１．１～４．５ｍｇ／ｋｇ，容重降低０．０５～０．０８Ｍｇ／ｍ＾３，而且多收一季豆类作物，其中豆类籽粒产量１５７８ｋｇ／ｈｍ＾２，绿肥鲜草产量１８７５０ｋｇ／ｈｍ＾２，后茬作物小麦增产率６．７％～１０．６％。

Genetic Stability of Resistance of Bean （Phasedus vulgaris L.） to Glyphosate

Thirty lines of bcan were tested for resistance to glyphosate in the field.Obvious difference in resistance response to glyphosate was detected when glyphosate was applied at the rate of 1kg ai/ha on the 15th day after emergence of seeclings.The ling 89-05 showed high resistance with a survival of 77%.Even after glyphosate was reapplied.the survival rats was still 20%,Obvious segregation was found in Progency of 89-05 for resistance to glyphosate;the survival rate of lined 89-05-1 89-05-2 and 89-05-3 were,respectivcly,42.3%,51.4% and 85.7%,at 1kg ai/ha of the herbicide with a survival of 77%.Even after glyphosate was reapplied.the survival rate was still 20%,Obvious segregation was found in progency of 89-05 for resistance to glyphosate;the survival rate of lined 89-05-1 89-05-2 and 89-05-3 were,respectively,42.3%,51.4%and 85.7% at 1kg ai/ha of the herbicide.Progenies 89-05-3 continued to show resistance and lines 89-05-3-5and 89-05-3-7 both had a survival rate of 100%,When glyphosate was applied with a rate over 1keqia/ha,the survival rate of the 89-05-3-5 was still between 50%-98%.
