室内试验表明，在３０℃、２５℃、１８℃３种温度条件下，包衣子的出苗率、出苗速率、苗高、苗重、根重均低于光子。在３０℃和２５℃时，包衣子的出苗率还低于毛子，而包衣子的苗病率和根病率低于光子和毛子。种衣剂１１号对包衣棉种具有保苗效果，同时又有抑制作用。低温试验是检验种子活力水平保证一播全苗的好方法。
Laboratory tests showed that the seed germination rate, seedling height, seedling weight and root weight were all lower than those of photons under the conditions of 30 ℃, 25 ℃ and 18 ℃. At 30 ° C and 25 ° C, the rate of emergence of the coated seed was lower than that of the wool, while the rate of the seedling and the root rate of the coated seed were lower than those of the photon and the wool. Seed coating No. 11 on the cotton seedlings have seedling effect, but also inhibitory effect. Low temperature test is to test the seed level of seed to ensure a good way to seedlings.
