萝卜叶面积测定方法研究

Study on Estimate of Leaf Area of Radish

潍县萝卜叶面积形成与施肥量呈正相关。

Weixian radish leaf size shape had a significantly positive correlation with fertilization volumes .

不同氮肥种类对潍县萝卜叶面积形成的影响差异不明显。

There were no significant difference that the impact of different types of nitrogen fertilizer on Weixian radish formation of leaf area .

ALA对萝卜不同叶位叶片光合作用与叶绿素荧光特性的影响

Effects of 5-aminolevulinic Acid on Photosynthesis and Chlorophyll Fluorescence of Radish Seedlings

由此形成在萝卜长叶期进行苗期单位面积叶鲜重测定；

In the period of radish to grow leaf the fresh weight unit area was menstruate ;

然而，在山区进行蔬菜种子生产，从经济上考虑，只有萝卜和叶用芥菜种子生产有效益，而大白菜种子生产没效益。

However , when seed production was considered economically on the highland , only Chinese radish and leaf mustard seed production was profitable , but not for Chinese cabbage .

恢复氮、磷、钾供应时，萝卜的叶面积及地上部分鲜干重随着氮浓度的增加而逐渐增加，随着磷、钾浓度的增加其值变化不大。

When N , P , K were supplied , the leaf area , flesh and dry weight of leaf were increased with the rising of N concentration , but which were not affected by P , K concentration .

其中白萝卜、地瓜叶、大白菜、青菜等超标严重。

The nitrate content of radish , pachyrhizus , cabbage and greengrocery is much higher above the required limit .

并且芹菜、莴笋、水萝卜三种蔬菜叶中黄酮含量远高于其茎中。

Flavonoids content in celery , lettuce and radish is much higher than in their stems or roots .

结果表明，桃蚜和萝卜蚜两种菜蚜，主要在嫩叶和老叶的背面取食，成叶背面也有一定数量，但萝卜蚜在成叶上的发生比率较桃蚜明显要高。

The results showed that the two aphids , namely Myzus persicae and Lipaphis erysimi , mainly fed on the underside of young and old leaves .

以上数据推断出，GMP可能在萝卜肉质根AsA累积中起着重要的作用。（3）比较了在光照处理下萝卜成熟叶、幼叶、根肉以及根皮4个部位中AsA含量的变化。

The data suggested that GMP could play an important role in the regulation of ascorbate accumulation during radish fleshy taproot development . ( 3 ) Compared the AsA contents of mature leaves , young leaves , root flesh and skin of radish under light treatment .

滴灌下萝卜肉质根中可溶性糖含量和维生素C含量比漫灌下萝卜肉质根内含量高。（5）不同灌溉方式对萝卜的叶水势日变化没有明显的影响。

The contents of the soluble glucide and the vitamin C in the root of the radish under the condition of drip irrigation were higher than those under flood irrigation . ( 5 ) . Different treatments had no significant impact on the daytime changes of the leaf potential .
