不同棉花品种适宜机采性状比较研究

摘要

For the requirement of machine-harvesting cotton variety,choosing 13 different cotton varieties authorized by Shandong Province in recent years,the differences of growth process,agronomic traits,yield,fiber quality and defoliation characteristics were compared and evaluated.The results showed that five traits of Luza 311 and Lumianyan 36,four traits of the Lumianyan 37 and Lu 6269,three traits of the Lu HB Biaoza-5 and Lumianyan 21,two traits of Yinxingmian 4 and K836 were in accordance with the requirement of machine-harvesting cotton.Under the experimental conditions,Luza 311,Lumianyan 36 and Lumianyan 37,Lu 6269,Lu HB Biaoza-5 and Lumianyan 21 were more suitable for machine-harvesting.%针对棉花机械采收对品种的要求,选取13个山东及河北省近年审定棉花品种,研究评价其在生育进程、农艺性状、产量性状、纤维品质和脱叶特性诸方面的差异.结果表明:鲁杂311、鲁棉研36号5类性状全部符合机采棉要求;鲁棉研37号、鲁6269两品种有4类性状表现较优;鲁HB标杂-5、鲁棉研21号在3类性状方面表现较优;银兴棉4号、K836在2类性状方面符合机采要求.所以,本试验条件下,鲁杂31 1、鲁棉研36号、鲁棉研37号、鲁6269、鲁HB标杂-5、鲁棉研21号为较适宜机械采收的棉花品种.
