1苗情特点1.1群体适宜当前农田平均总茎数1 027.5万/hm2,比越冬前增加75.0万/hm2;大蘖525.0万/hm~2,比越冬前增加67.5万/hm2。其中总茎数、大蘖与常年同期略低,群体整体较适宜。1.2个体转壮小麦平均单株叶片,比冬前增加0.4片叶,比2015年同期少1.0片叶;单株分蘖2.5个,比冬前考察时增加0.4个,比2015年同期少0.8个;单株次生根2.92条,比冬前考察时增加0.70条,比2015年同期少1.00~2.00条。
1 seedling characteristics 1.1 population suitable for the current average total number of farmland stem 12,075,000 / hm2, increased by more than 750,000 before winter / hm2; big tiller 5,250,000 / hm ~ 2, an increase of 675,000 / hm2 than before winter. Among them, the total number of stems, big tillers and slightly lower than the same period perennial, the population as a whole is more appropriate. The average number of individual leaves per plant increased by 0.4 leaf as compared with that before winter and 1.0 leaf less than the same period of 2015. The number of tillers per plant was 2.5, which increased by 0.4 compared with that before winter and 0.8 less than the same period in 2015. The number of secondary roots per plant was 2.92, which increased by 0.70 compared with that before the winter survey, 1.00 ~ 2.00 less than the same period in 2015.
