壮秧是高产的基础,播量是影响秧苗素质的重要因素。我们于1981～1982年进行了早稻秧田播量的试验,试从秧田群体动态的角度,分析不同播量对秧苗素质的影响,以为确定合理播量提供一些依据。 试验方法 试验于1981～1982年在本所进行,试验田为四纪红壤发育的粘质土,在我县属中上肥力 Seedling is the basis of high yield, sowing rate is an important factor affecting the quality of seedlings. In 1981 ~ 1982, we conducted experiments on the sowing rate of early rice seedlings. The effects of different sowing rates on the quality of seedlings were analyzed from the perspective of seedling population dynamics to provide some evidence for determining the reasonable sowing rate. Test method The experiment was carried out in our institute from 1981 to 1982, and the experimental field was clay soil developed in the fourth-century red soil.
