摘要
为探究单穴不同留苗数对晋谷21号茎秆机械强度及抗倒伏能力的影响,研究了在单穴留苗数为1,2,3,4,5株下的晋谷21号的茎秆特性,比较了单穴留苗数对茎秆机械强度和倒伏指数的影响。结果表明,晋谷21号在单穴留苗3株时,植株茎秆机械强度最高,倒伏指数最低;其次为单穴留苗2,4株。
To explore the effect of different leaving seeding number each hole of Jingu 21 culm mechanical strength and lodging resistance, under each hole for seedling number from 1 to 5, the effect of culm characters of Jingu 21 was studied, the influence of the each hole leaving seedling number on the culm mechanical strength and culm lodging resistant index was compared. The results showed that when Jingu 21 leaving seedling number at each hole was 3, the culm mechanical strength was the highest and the culm lodging resistant index was the lowest, followed by 2 and 4 at each hole leaving seeding.
