喷洒高脂膜对防治甜菜褐斑病及产量效应的初步研究

Preliminary Study on the Spraying Higher Fatty Acohl Emulsion Effect on Controlling Sugarbeet Leaf Spot and on the Root Yield

本文研究了高级脂肪醇水乳剂(简称高脂膜)对甜菜褐斑病防治及产的作用。结果表明:甜菜叶簇生长、单位面积叶片重、功能叶片寿命和叶绿素含与甜菜的有关生理特性之间,受高脂膜浓度相互制约,存在差异性。

Three—year experemental result shows:Spraying sugarbeet foliage with Higher Fatty Acohol Emulsion for2-3 timesduring sugarbeet plants growing stake can prevent sugarbeet plants fromleaf spot.The averge preventive result is about 58% and highest preventiveresult is about 81.5%.And in generally,it can increase the sugarbeet rootyield by 12.8%,sugar yield by 17.7%.Higher Fatty Acohol Emulsion have the action of adjusting sugarbeetgrowth and the plants can escape from forage spindling after applying it.In the meantime,it can promote the formation of chlorophyll and lengthenthe longevity of functional leaves.
