一、种子发芽势差目前,市场上销售的种子,发芽率大部分达到国标,但是其中有一部分种子的活力差,发芽势不高,发芽势高的种子在种植条件适宜的条件下,能迅速出苗,且苗齐苗壮。即使稍遇逆境,也能一播全苗。发芽势低的种子在出苗过程中,稍遇逆境(例如阴雨、低温等),便会受到影响,造成出苗率低,成苗率不高。即使有 First, the seed germination potential difference Currently, the market sales of seeds, most of the germination reached the national standard, but some of them have poor vitality, sprouting potential is not high, high potential seed germination conditions suitable for planting, quickly Emergence, and Miao Miao Zhuang strong. Even a slight adversity, but also a broadcast seedlings. Seeds with low germination potential will be affected during the emergence process with a slight adverse adversity (eg rainy weather, low temperature, etc.), resulting in low emergence rate and low seedling rate. Even if there is
