苯磺隆对枣树营养生长及叶绿素含量的影响

针对枣麦间作地杂草防除 ,选用苯磺隆不同浓度进行试验 ,对枣树新梢生长量、叶面积、叶绿素含量及开花情况作了测定 ,结果表明 ,Ⅱ号处理对枣树的新梢生长量、叶面积和叶绿素含量影响很小 ;Ⅰ号处理比对照枣树新梢生长量降低 4 4 71%、叶面积减小 2 8 85 % ,叶绿素含量降低 31 5 % ;Ⅲ号处理对枣树新梢生长量 ,叶面积和叶绿素含量均受到严重影响 ,分别降低 71 37%、 96 15 %、 34 2 %。经方差分析表明 ,三种浓度对枣树开花的影响 ,Ⅱ号达显著水平 ,Ⅰ、Ⅲ号达极显著水平

Effect of Herbicide Tribenjuron - methyl on the Vegetation growth and the Chlorophyll Content of Zizy-phus jujuba Mill

A series of concentrations of herbicide Tribenjuron-methyl were applied to the fields where Zizyphus jujuba Mill. and beans were intercroped. The results showed that the growth amount in new tips, leaf areas and chlorophyll's content of Zizyphus jujuba Mill. in the fields treated with Ⅱ were little influenced. However, the growth amount in new tips, the leaf areas and the chlorophyll's content of Zizyphus jujuba Mill.treated with Ⅰ were reduced by 44 7%,28 85%,and 31 5% respectively. And the new tips growth amount, the leaf areas and the chlorophyll's content of Zizyphus jujuba Mill. treated with Ⅲ reduced by 71 37%,96 15% and 34 2% respectively. By statistics analysis, the result indicated that the blossoms of Zizyphus jujuba Mill. treated with Ⅰand Ⅱ were very remarkable, and with Ⅱ was marked.
