河西走廊西部玉米机械粒收质量影响因素分析
Analysis of factors influencing the maize mechanical grain harvest quality in the western of Hexi Corridor
摘要
Abstract
[Objective]To improve the maize harvest quality and to extend the application of maize mechanical grain harvesting in western Hexi Corridor.[Methods]In 2023,the harvest quality test in field of 10 different maize cultivars was carried out in Xiaheqing Farm,Jiuquan City,Gansu Province in which,the same mechanical was used to harvest and the the grain moisture content,grain breakage rate,impurity rate,and field loss rate of sampled and tested after harvest.[Results]On average,the grain moisture content,grain breakage rate,impurity rate,and field loss rate of tested cultivars were 26.25%with a variation of 17.80%-33.10%,8.13%with a variation of 2.96%-19.80%,0.86%with a variation of 0.02%-3.26%,and 3.58%with a variation of 3.51%-3.64%,respectively.There was a extremely significant positive correlation between grain breakage rate and grain moisture content(P<0.01),which could be described with a fitting equation:y=-0.466 1e0.1002x(R2=0.405 7)that grain breakage rate would reach its lowest when grain moisture content were 17.10%;another extremely significant positive correlation was also found between impurity rate andgrain moisture content(P<0.01),which could be described with a fitting equation:y=0.001 5e0.2177x(R2=0.454 7)that impurity rate would be minimized when grain moisture content were 16.40%;while field loss rate was negatively correlated with grain moisture content,which could be described with a fitting equation:y=1E-06x4-0.000 3x3+0.015 3x3-0.324 0x+5.928 2(R2=0.299 2)that field loss rate would be the least when grain moisture content were 20.20%.[Conclusion]The overhigh grain moisture content on harvesting is the major affecting factor on the maize mechanical grain harvesting quality in the western of Hexi Corridor.By selecting suitable cultivars and scientifically arranging harvesting time,the maize mechanical grain harvesting quality will be improved in the western Hexi Corridor.关键词
