5种药剂对西瓜草甘膦药害的恢复效果

The mitigation effect of 5 kinds of agentia on the glyphosate's phytotoxicity of watermelon

随着大棚西瓜种植面积增加和田间草害的日益严重,除草剂在大量应用于田间除草的同时,产生的药害问题也越来越突出。通过观察、拍照,测定植株生长指标、产量及品质等,初步明确了西瓜草甘膦药害症状,研究了5种药剂对西瓜草甘膦药害的恢复效果,旨在为解决西瓜草甘膦药害问题提供方法和途径。田间试验表明,草甘膦药害对西瓜生长产生严重影响,导致西瓜产量降低24%,喷施碧护和快克能够恢复植株生长,显著增加植株蔓长和叶片数,并利于干物质的积累,生物硼钾肥可提高西瓜产量28%,提高中心可溶性固形物含量10.58%,基因活化剂可以改善西瓜品质,提高中心可溶性固形物含量11.33%。综合看来,碧护和快克对草甘膦药害西瓜植株生长的改善效果较好,基因活化剂和生物硼钾肥能够有效提高西瓜产量、改善品质。

With the increase of the planting area of watermelon and the increasingly serious weeds in the field, the herbicides are becoming more and more important, at the same time, the phytotoxicity is becoming more and more serious,so the study on mitigation techniques of watermelon herbicide phytotoxicity is of great significance. In this study, the mitigation effects of different agentias on the glyphosate＇s phytotoxicity of watermelon were studied. The results showed that watermelon was seriously affected by glyphosate, and the yield decreased by 24%. After spraying the Bihu and Kuaike, the plant growth resumed quickly, the vine length, leaf number and dry matter increased significantly. When spraying the Biological boron potash, the yield and the central soluble sugar content increased by 28%, 10.58%,respectively. The Gene activator could improve the quality, and the central soluble sugar content increased by 11.33%.In conclusion, Bihu and Kuaike had obviously mitigation effects on watermelon seedling growth, Gene activator and Biological boron potash effectively increased the yield and improved the quality of watermelon.
