扬麦5号小麦在我市已种植五年。在种植过程中,由于年度之间的外界条件不同,导至扬麦5号的生长出现两种类型,即早发类型和迟发类型。所谓早发,就是在越冬期(1月20日)每亩茎蘖数达到或超过45万,如1985年、1987年,所谓迟发,就是在此时每亩茎蘖数不到45万,如1984年、1986年。为了进一步认识扬麦5号在不同年景下高产的生育特点及其变化规律,提高在不同年景下的栽培水平,现将有关扬麦5号在不同年景下高产特点及栽培要点归纳如下。
Yang Mai 5 wheat has been planted in the city for five years. In the planting process, due to the different external conditions between the year, led to the growth of Yangmai 5 appeared two types, namely, early onset type and delayed type. The so-called early onset means that the number of stems and tillers per mu reached or exceeded 450,000 during the wintering period (January 20). In 1985 and 1987, the so-called late onset means that the number of stems and tillers per mu is less than 450,000 at this time, Such as 1984, 1986. In order to further understand Yangmai 5 in different years of high yielding fertility characteristics and changes in law, to enhance the level of cultivation in different years, now on Yangmai 5 in different years of high yield characteristics and cultivation points are summarized below .
