摘要: 为研究植物油助剂对棉花脱叶和吐絮效果及产量的影响,设置植物油0、600、900、1200 g/hm2 4个剂量处理,以烷基乙基磺酸盐助剂为对照,应用剂量1500 g/hm2。脱吐隆和乙烯利用量分别为180 g/hm2和1200 g/hm2。在相对低温条件下于新疆玛纳斯县和呼图壁县2 个试验点同时进行了大田应用效果试验,分析了各处理棉花脱叶率、吐絮率及产量的差异。结果表明添加900 g/hm2植物油助剂处理的最终脱叶率和吐絮率显著高于对照处理和植物油0 剂量处理,分别达到95%和96%以上(P<0.05)。相对低温条件下植物油助剂对棉花脱叶和催熟具有显著增效作用,用量以900 g/hm2最为理想。

Abstract: In order to study the effect of vegetable oil additive on the defoliation, boll opening effect and yield of cotton, alkyl ethyl sulfonate is taken as the control (1500 g/hm2), 4 kinds of vegetable oil application dosages are set up, including 0, 600, 900 and 1200 g/hm2. Under the relative low temperature, a field application test is conducted in two sites, Manas County and Hutubi County, Xinjiang. The differences of defoliation, boll open rate and yield are analyzed. The results showed that the final defoliation rate and boll open rate with 900 g/hm2 vegetable oil additives treatment was significantly higher than that of the control and 0 g/hm2 vegetable oil treatment, reached over 95% and 96% , respectively (P <0.05). In conclusion, vegetable oil additives have significant synergistic effect on defoliation and ripening of cotton under low temperature, and the dosage of 900 g/hm2 is the best.
