由于玉米杂交制种田与玉米大田栽培技术操作规程存在的差异,所以导致两者测产方法不尽相同。为更能准确地反映玉米杂交制种田的真实产量,需要一套适用玉米杂交制种田的测产方法。我公司从1972年就开始探讨令适的测产方法,特此提出供大家参考。1 测产时期玉米杂交制种田同玉米大田测产时期相同,适宜在蜡熟后期进行。因为在这个时期,于物质积累基本 Due to differences in maize hybridization farming practices and corn field cultivation techniques, resulting in both methods of measurement are not the same. In order to more accurately reflect the true yield of maize hybrid system of farming, you need a set of methods for the production of hybrid corn for farming. My company started from 1972 to make appropriate measurement method, hereby proposed for your reference. 1 production period of corn hybrid field farming with corn field same period, suitable for waxy later. Because in this period, accumulation of material basic
