棉花脱叶剂的田间效果筛选

Screening Test of Different Disleave Agents for Accelerating Effect

【目的】主要研究卫绿环脱叶剂在田间应用中的脱叶效果及其对单铃重、衣分、纤维长度、马克隆值和产量的影响。【方法】田间小区试验测定。【结果】喷施卫绿环脱叶剂20 d后平均脱叶率可达93.2%,略高于瑞脱龙,与脱吐隆脱叶效果大致相近。喷施卫绿环脱叶剂对棉花单铃重、衣分、纤维长度、马克隆值和产量无显著影响,卫绿环脱叶剂适宜在机械采棉中应用。【结论】喷施卫绿环脱叶剂脱叶效果好,价格适中,适宜在机采棉地区大面积推广。

【Objective】In this experiment,the field efficacy of different disleave agents for accelerating effect of disleave,boll weight,lint percentage,fiber length and micronaire as well as yield were completed.【Method】The test was carried out by field plot experiments.【Result】It was showed that the accelerating effect of disleave after Weilvhuan disleave agent treatments 20d was 93.2%,which was higher than Ruituolong and close to Thidiazuron.No significant difference of boll weight,lint percentage,fiber length and micronaire as well as yield was observed between Weilvhuan disleave agent treatment and control treatment.【Conclusion】The results indicated that the best accelerating effect of disleave of disleave agent was Weilvhuan disleave agent in agricultural production for its high efficiency and low cost.
