培育壮苗涉及的因素较多,而合理确定秧田播量是重要因素之一.近年来,有的生产单位为了节约薄膜,盲目增加秧田播量,导致秧苗素质下降,插后返青较慢,有的死苗比较严重,影响插秧面积.为此,1981年我们设置了不同播量试验,调查了秧苗的生长情况、秧本田比例、插后的返青、分蘖情况.得到一些结果. In recent years, some production units in order to save the film, blindly increase the sowing of seedlings, resulting in decreased quality of seedlings, plug back green after the slow, there are Of the dead seedlings is more serious, affecting the area of ​​transplanting.For this reason, we set different sowing experiments in 1981, investigated the growth of seedlings, the proportion of transplanting Honda, plugging back green, tillering.We got some results.
