摘要:

为了验证免疫诱抗剂对小麦具有促生、防病、增产和提质的效果,本研究通过对比维大力、氨基寡糖素、常规化学药剂和空白对照在小麦拌种及叶面喷施应用的效果,研究其对小麦秧苗素质、纹枯病防治效果、赤霉病防治效果、产量及呕吐毒素的影响。结果显示,利用维大力进行小麦拌种处理能显著增加小麦根长,促进次生根产生;在小麦拔节期喷施免疫诱抗剂对纹枯病防治效果达83.33%,显著优于常规药剂;在小麦抽穗扬花期喷施免疫诱抗剂对赤霉病防治效果达96.45%~98.05%,显著降低了呕吐毒素产生;利用免疫诱抗剂在拔节期和扬花期与常规药剂配合使用,可显著提高小麦籽粒实粒数,较单用常规药剂增产12.1%~13.7%。免疫诱抗剂在小麦应用上具有较高价值。

Abstract:

In order to verify the effects of immune inducers on wheat growth, disease prevention, yield increase and quality improvement, the effects of VDAL, amino-oligosaccharides, conventional chemicals and blank control on wheat seedling quality, sheath blight control effect, gibberella control effect, yield and vomitoxin were studied by comparing the effects of vitamin oligosaccharides, conventional chemicals and blank control on wheat seed dressing and foliar spraying. The results showed that wheat seed dressing treatment with VDAL could significantly increase the root length of wheat and promote the production of secondary roots, the control effect of spraying immune inducers on sheath blight at the jointing stage of wheat was 83.33%, which was significantly better than that of conventional pesticides, and the control effect of spraying immune inducers on scab at the heading and flowering stage of wheat was 96.45%-98.05%, significantly reduced the production of deoxynivalenol. The use of immune inducers in combination with conventional pesticides at jointing stage and flowering stage could significantly increase the number of grains in wheat, and the yield was increased by 12.1%-13.7% compared with conventional agents alone. Immune inducers have high value in wheat applications.
