| 利用不同孔径的防虫网为覆盖材料，以露地栽培为对照，研究不同孔径防虫网对菜心生长的影响，以期为生产上利用网室栽培菜心提供理论依据。结果表明：夏季防虫网覆盖栽培可以有效防治各种害虫，减少农药使用量，提高菜心产量，同时也提高了菜心的株高和节间长度、可溶性糖、还原糖和果糖的含量。防虫网覆盖栽培还降低了菜心臺茎的硝酸盐含量，提高了叶片的可溶性蛋白含量。综合考虑生产上宜采用孔径为0.710 mm的白色防虫网更适合夏季菜心种植。 |

| In order to provide theoretical evidence for Flowering Chinese Cabbage production of insect-proof net, we compared different pore size of insect-proof net and open field on the effects of Flowering Chinese Cabbage growth. The results showed that in summer the insect-proof net cultivation could prevent different pets effectively, reduce the usage amount of pesticide and improve the yield, and also increase its plant height, internode length, the content of soluble sugar, reducing sugar and fruit sugar. Besides, insectproof net could also decrease the nitrate content of Flowering Chinese Cabbage bolting stem, increase the soluble protein content of leaf.In conclusion, the pore size of 0.710mm of insect-proof net was more suitable for Flowering Chinese Cabbage growth in summer. |
