不同水稻苗床调理剂对机插秧秧苗素质的影响
Effect of Different Rice Seedbed Conditioners on Quality of Mechanically-transplanted Rice Seedling
摘要
Abstract
The japonica rice "Ningjing No.4" was used to carry out the plot experiments of seedling breeding with plastic plate, and the effects of three kinds of seedbed conditioners on the quality of the mechanically - transplanted rice seedlings were studied. The results showed that: in comparison with the control, the rice seedbed conditioners "Hailing" and "Chengxin" could significantly reduce the seedling height, speed up the rate of leaf emergence, reduce the maximal leaf length, expand the maximal leaf width, and increase the basal stem width, root weight, ratio of root to shoot, root twisting power and rooting capacity. The rice seedbed conditioner "Chunquan" could significantly increase the seedling height, maximal leaf length, maximal leaf width, basal stem width and shoot weight, speed up the rate of leaf emergence, but it had little effect on the ratio of root to shoot, root twisting power and rooting capacity. In short, "Hailing" and "Chengxin" could improve the quality of rice seedlings for mechanical transplanting, and extend the seedling age, thus they were worthy of popularizing and applying.关键词
