呼伦贝尔地区早熟抗逆宜机收玉米品种鉴选标准研究
|
摘要
本研究以内蒙古近几年审定的玉米新品种为主,对照为国家或自治区品种试验对照品种,依据宜机收玉米品种选择标准,进行呼伦贝尔地区早熟、抗逆、宜机收玉米品种鉴选标准试验。结果表明,德美亚1号熟期极早熟组品种机械收获破损率应≤0.3%,破碎率应≤2.2%,成熟期籽粒水分≤28.66%,收获水分≤25.53%。丰垦008熟期早熟组的品种机械收获破损率应≤0.3%,破碎率应≤2.4%,成熟期籽粒水分≤29.05%,收获水分≤25.37%。九玉1034熟期中早熟组的品种机械收获破损率≤0.5%,破碎率≤7.3%,成熟期籽粒水分≤30.98%,收获水分≤29.85%。根据试验各项分析最终结果,筛选宜机收品种为J6518、富成99和A2636。
Taking the new maize varieties examined in Inner Mongolia in recent years as test materials,the national or regional approved varieties as control varieties,according to appropriate identification standard for maize varieties which were appropriate mechanically harvesting in Hulun Buir area,the identification standards of maize varieties with early maturity,tolerance and appropriate mechanically harvesting were studied.The results showed that the mechanical harvesting damage rate of the maturity group of Demeiya 1 should be less than or equal to 0.3%,the broken rate should be less than or equal to 2.2%,the moisture of mature period is less than or equal to 28.66%,the moisture of harvest period is less than or equal to 25.53%.The mechanical harvesting damage rate of the maturity group of Fengken 008 should be less than or equal to 0.3%,the broken rate should be less than or equal to 2.4%,the grain moisture of mature period was less than or equal to 29.05%,the grain moisture of harvest period was less than or equal to25.37%.The mechanical harvesting damage rate of the maturity group of Jiuyu 1034 should be less than or equal to 0.5%,the broken rate was less than or equal to 7.3%,the grain moisture of mature period was less than or equal to 30.98%,the grain moisture of harvest period was less than or equal to29.85%. According to the results,best maize varieties with early maturity,tolerance and appropriate mechanically harvesting are J6518,Fucheng 99 and A2636.
