叶面喷施噻苯隆次数及喷施时期对棉花生长发育及产量的影响
Effects of foliage spraying thidiazuron times and periods on growth and yield of cotton
摘要
Abstract
[Objective]In order to screen out the suitable thiabilone spraying period and times in the process of cotton growth and development,the effects of foliar spraying of thidiazuron reagent on cotton growth and yield will be studied.[Methods]In 2021,the experiment of Pencil Thiophenone was carried out in Dafeng Town,Hutubi County,Changji Hui Autonomous Prefecture.The cotton variety Xinluzao 82 was used as the test material.150 mL/hm2 was used as the spraying standard,and T1,T2,T3 were used as the spraying treatments once,which were sprayed in bud,flower and boll stages respectively.T4,T5,T6 were sprayed twice,respectively,in bud and boll stage,bud and boll stage,boll and boll stage.T7 was sprayed for three times,spraying once in bud-blooming,flowering and boll-blooming stages.There were 7 treatments and one clean water control.The effects of spraying times and spraying cycle of Thidiazuron on agronomic traits,dry matter accumulation and distribution,yield and quality of cotton were studied.[Results]The results showed that the number of fruit branches and bolls in T5 treatment increased by 1.8 and 3 compared with the con-trol.After 60 days of application,the dry matter accumulation of T5 treatment increased by 28.94 g compared with CK,and the dry matter of reproductive organs accounted for a larger proportion than CK,increasing by 6.5％.Compared with CK,the effective boll number and single boll weight of cotton treated with T5 increased by 0.45 and 0.37g,respectively,and the yield of seed cotton and lint cotton treated with T6 increased by 20.7％and 17.9％,respectively.Compared with CK,the fiber length of the top half of T5 treatment increased by 0.4％.[Conclusion]It is recommended to spray thidiazuron twice,and spraying it in full bud stage can promote the growth and development of cotton.Spraying it in full boll stage can increase the yield of cotton,and using thidiazuron as a plant growth regulator has a positive effect on cotton.关键词
