水稻抛秧栽培是继水稻机插、水稻直播之后的又一种水稻轻型栽培技术。由于它具有省工、高产、高效等优点,被农民誉为一种愉快的劳动正日益推广使用。与常规移栽水稻相比抛秧水稻因空中飞栽作业,秧苗在田间的分布格局缺乏规律性,株行距配制混乱,难免会形成大小不等的空白无苗区(即空档)。空档过多过大将直接影响产量的提高,同时,会导致农民有匀苗补缺花工多的顾虑。为此,我们连续两年针对抛秧稻田间空档对生育和产量的效应作了较为深入的试验研究,旨在探讨明确适宜的空档大小和配置,为发展大面积抛秧水稻高产高效 Throwing Rice Cultivation is the rice planting machine, rice after planting another light cultivation techniques. Because it has the advantages of labor-saving, high yield and high efficiency, the peasants hailed as a pleasant work is being promoted. Compared with the conventional transplanting rice, the transplanted rice transplanted in the air had no regularity in the distribution pattern of the seedlings in the field. Too much will directly affect the increase in output, at the same time, will lead to farmers have a lot of seedlings fill more missing concerns. Therefore, for two consecutive years, we conducted a more in-depth experimental study on the effects of paddy field neutrality on fertility and yield in order to explore the appropriate and appropriate gap size and configuration. In order to develop a large area of ​​paddy rice with high yield and high efficiency
