摘要
[目的]研究无人机喷施不同浓度缩节胺对棉花生长发育的调控效应,为构建棉花轻简栽培提供科学依据.[方法]在缩节胺剂量相同的条件下,共设置 6 个不同兑水量控制缩节胺浓度(缩节胺分次分时期喷施,共7 次),分别为7.5(C1)、15(C2)、22.5(C3)、30(C4)、37.5(C5)、45(C6)L/hm2,分析不同缩节胺浓度对棉花生长发育的影响.[结果]喷施低浓度缩节胺(C5、C6)会延长棉花生育期,使棉花贪青晚熟;中浓度缩节胺(C3、C4)处理的棉花株高较低,对棉花株高抑制效果最好,其中C4 处理产量最高;高浓度缩节胺(C1、C2)处理会使棉花生育时期提前,缩短生育期,促早熟,但不利于伏前桃增长,还会降低棉花单铃重.[结论]新疆南疆地区种植棉花使用无人机化控时,选择兑水量为30 L/hm2(C4)的调控效果最优,且皮棉产量达到 2 762.6 kg/hm2.
Abstract
[Objective]To study the regulation effect of different knot-cut amide concentrations on cot-ton growth,and to provide a scientific basis for the construction of light and simple cultivation.[Methods]Under the condition of the same dosage,the concentration concentration was controlled A total of 6 water vol-ume were set,respectively 7.5(C1)、15(C2)、22.5(C3)、30(C4)、37.5(C5)and 45(C6)L/hm2,to analyze the effects of different acetamine concentrations on the growth and development of cotton.[Results]The spra-ying of low concentration(C5 and C6)will prolong the growth period of cotton and make the cotton mature late;the cotton plant treated with medium concentration(C3 and C4)is the best,in which the C4 treatment has the highest yield;the high concentration of acetamide(C1 and C2)will advance the cotton growth period,shorten the growth period,promote the growth of peach,and reduce the single bell weight of cotton.[Conclu-sion]In the use of cotton in southern Xinjiang,the control effect of the water amount was 30 L/hm2,and the yield reached 2,762.6 kg/hm2.
