无人机喷施缩节胺对棉花光合及叶片生理特性的影响
Effects of UAV application of arthrothylamine on photosynthesis and leaf physiological characteristics of cotton
摘要
Abstract
[Objective]To investigate the effects of the interaction between the frequency and dose of arthropyl amine application on the photosynthesis and leaf physiological characteristics of cotton based on the whole-process chemical control of unmanned aerial vehicle(UAV)with a view to providing the scientific basis for the construction of light and simple cultivation of cotton was provided.[Methods]A two-factor split plot design was used in the experiment.The main plot was the application times of knotylamine,T1 was applied for 6 times during the whole growth period,T2 was applied for 4 times during the whole growth period.The secondary area was the dose of arthroacetamine,and 5 chemical control doses were set,the total amount was C1:11.6 g/667 m2,C2:17.4 g/667 m2,C3:23.2 g/667 m2,C4:29 g/667 m2,C5:34.8 g/667 m2,respectively to study the regulatory effects of UAV application of arthrostatin on physiological characteristics of cotton.[Results]After 6 times of application,the contents of malonaldehyde,peroxidase,soluble sugar and soluble protein increased with the flat application of knotylamine,indicating the stress effect of knotylamine.When spraying for 4 times,the high concentration of lumen led to higher content of malondialdehyde,peroxidase,soluble sugar and soluble protein in the final leaves,which was not conducive to the development of cotton boll and easy to appear"empty"phenomenon.Compared with the two spraying times,the 6 spraying times increased the intercellular CO2 concentration by 8.69%,providing raw materials for the photosynthesis of leaves,and the net photosynthetic rate of leaves increased by 68.07%in the early stage of boiling,prolonging the photosynthetic time of leaves.The intercellular CO2 concentration,peroxidase and soluble protein contents increased with the increase of the amine dose,while the soluble sugar contents increased first and then decreased under the same spraying times.[Conclusion]When unmanned aerial vehicle chemical control is considered to be used in cotton cultivation in southern Xinjiang,during the whole growth period,if 6 times of chemical control is applied,C4 treatment is recommended,and the total amount of arthrococtin is 29 g/667 m2;During the whole growth period,if 4 times of chemical control is applied,C3 treatment is suggested,and the total amount of arthrococtin is 23.2 g/667 m2.关键词
