植物生长调节剂复配不同叶面肥对棉花干物质积累及产量品质的影响

Effects of plant growth regulator combined with different leaf fertilizer on the accumulation of dry material and yield quality in cotton

【目的】研究植物生长调节剂胺鲜·甲哌鎓复配不同叶面肥对棉花生长发育的影响,分析胺鲜·甲哌鎓复配不同叶面肥对棉花的增产效果。【方法】试验于2021年在新疆呼图壁大丰镇进行,选用棉花品种为新陆早82号,以植物生长调节剂胺鲜·甲派鎓为主,分别复配缩节胺,助剂,硼锌肥,亚鳞酸钾,硅肥;单施缩节胺为对照。分析不同处理对棉花的农艺性状、干物质积累与产量品质的影响。【结果】不同处理对株高呈现不同的调控力度,其中胺鲜·甲哌鎓+助剂+硼锌肥处理抑制株高的能力较强;叶面喷施胺鲜·甲哌鎓+助剂+亚磷酸钾的蕾铃干物质积累量在所有处理中最大,达到45.37 g/株,且干物质总重最高,达到83.71 g/株;喷施处理胺鲜·甲哌鎓+助剂+硼锌肥的单株结铃数达到最大为6.78个/株,且单铃重最高为6.41 g,喷施胺鲜·甲哌鎓+助剂+亚磷酸钾收获籽棉产量最高,较对照高出10.42%。【结论】胺鲜·甲哌鎓+助剂+亚磷酸钾组合的增产效果最佳。

【Objective】To understand the effects of amine fresh and methylperidium compound on the growth and development of cotton,and to clarify the effect of amine fresh and meperamide compound on cotton yield increase of different foliar fertilizers,【Methods】The experiment was carried out in Dafeng Town,Hutubi County in 2021,using Xinluzao 82,mainly amine fresh and methyl,respectively,compounded acetylamine,auxiliary,borozin fertilizer,potassium scalemate,silicon fertilizer;Single administration of acetylamine was taken the control.In this experiment,the effects of different treatments on the agronomic traits,dry matter accumulation and yield quality of cotton were analyzed.【Results】The results showed that different treatments showed different degrees of regulation of plant height,among which the treatment of amine fresh meperidium+additive+boron zinc fertilizer had a strong ability to inhibit plant height.In terms of dry matter accumulation,the amount of drifting dry matter accumulated by foliar sprays of amine fresh,meperamide+additive+potassium phosphite was the largest in all treatments,reaching 45.37 g/plant,and the total dry matter weight was the highest,reaching 83.71 g/plant;In terms of yield,the number of bolls per plant sprayed with amine fresh,meperidium+additive+boron zinc fertilizer reached a maximum of 6.78 per plant,and the maximum weight of a single bell was 6.41 g,and the yield of seed cotton harvested by spraying amine fresh o meperidium+additive+potassium phosphite was the highest,which was 10.42%higher than that of the control.【Conclusion】Therefore,the combination of amine fresh o meperidium+auxiliaries+potassium phosphite has the best yield enhancement effect.
