摘要
[目的]筛选适合小麦包衣的新型高效种衣剂。[方法]选用市场上销售的4种小麦拌种剂,了解这4种小麦拌种剂对小麦出苗率、防病效果、干重、鲜重、农艺性状及产量的影响。[结果]处理①(2.5%的适乐时悬浮种衣剂)、处理②(25%的迈舒平悬浮种衣剂)、处理③(3%的敌萎丹悬浮种衣剂)能有效地提高小麦出苗率;在预防小麦纹枯病方面,4个处理较对照均有明显的差异;4个处理间产量差异不显著,但均较对照有所提高。[结论]25%的迈舒平悬浮种衣剂拌种在提高小麦出苗率、预防小麦纹枯病以及产量性状等方面均有显著效果,建议在生产上推广使用。
Abstract
Objective] To screen new and high-efficient seed-dressing agents suitable for wheat coating. [Method] We selected four wheat seed-dressing agents sold in the market, and researched the effects of four seed-dressing agents on the emergence rate, disease prevention effect, dry weight, fresh weight, yield and agronomic traits of wheat. [Result] Treatment①(2. 5% celest suspended seed-dressing agent ), treatment②(25% Maishuping suspended seed-dressing agent), treatment ③ (3% Dividend suspended seed-dressing agent) could effectively enhance the emergence rate of wheat. In the aspects of preventing wheat sharp eyespot, the four treatments both had significant differences compared with the control. There were no significant differences in yield of four treatments, but they all increased in different degree compared with the control. [ Conclusion] 25% Maishuping seed-dressing agent shows significant effects on wheat emergence rate, yield traits and the prevention of wheat sharp eyespot.
