水稻机插秧盘排水孔数量对秧苗素质的影响

Effect of Different Holes of Rice Tray on Seedling Quality

采用1 038孔、510孔、264孔、150孔、0孔机插秧盘,在不同秧板及育秧土上进行秧盘应用效果的分析比较。研究结果表明:旱地秧板育秧条件下,较少的秧盘排水孔数可以有效减缓秧盘水分流失速率,保水条件较好,出苗率也较高,促进了秧苗生长,同时起秧方便,根系较为盘结,不易松散;而泥浆秧板育秧条件下,较少的秧盘排水孔数阻碍了湿润泥浆对秧盘的水分供给,出苗率较低,秧苗生长反而受到抑制,虽然起秧力较小,但由于秧苗根系差,根系盘结力较低,易松散。

This study inves soil, conducted with 1038 trays can effectively reduce gence rates are higher. At ing. However less holes see tigated the effects of different holes trays on seedlings with different seedling plate and seedling hole, 510 hole, 264 hole, 150 hole, 0 hole trays. The results showed that less holes seedling water loss rate on the dryland plate, and the water conditions are better, the seedling emerthe same time, less holes seedling trays are easy for seedlings lifting and the root is intertwindling trays effectively prevented water supply from wet mud to the trays. The seedlings growth and the seedling emergence were inhibited. It was easy to lift trays, but the roots were poor and inattentive.
