农谚說:“肥田不如肥秧,十分稻九成秧”,可見培育壮秧是水稻增产的一个重要环节。秧苗素質的优劣与很多条件都有密切关系,其中施肥技术更为显著;但怎样合理施肥才能培育出壮秧,目前国內外意見还是不一致的,尤其缺乏試驗数据。为此,我們进行了秧田施肥技术的研究,試图从这方面为培育壮秧提供理論根据。一、試驗材料与方法本試驗是1963年在合肥本院进行的,供試品种为中秈三九九,分六个处理(表一)。
Agricultural proverb said: “Fertilizer is not as good as fertilizer seedling, rice is very Jiucheng seedlings”, shows that cultivating strong seedling is an important part of rice yield. The quality of seedling is closely related to many conditions, including fertilization technology is more significant; but how to fertilize to cultivate strong seedlings, the current domestic and international opinion is inconsistent, especially the lack of test data. To this end, we conducted seedling fertilizer technology research, trying to provide theoretical basis for cultivating strong seedlings in this regard. First, the test materials and methods This experiment was carried out in Hefei Hospital in 1963, the test varieties for the medium-sized three nine nine, divided into six treatment (Table I).
