近年沙田晚稻增产幅度不大,肥料不足是其主因;在技术上,与夏收夏种间隔期短,漚田期短,耕耙粗糙,插植期迟,品种不纯等有关,而秧苗不好也有一定关系。秧苗不好表现为“不壮”“不老”,而“不壮”最为主要。“不老”多由于利用早稻跡地为秧田,播期较迟;“不壮”则与基肥不足,杂草较多有关。因此,通过施用基肥,早施追肥,促进秧苗快长,抑制杂草丛生,以达壮秧目的是值得注意的。 In recent years, the yield of late rice in Shatian crop is small, and the shortage of fertilizer is the main cause. In terms of technology, it is related to the short summer interval, the short cropping period, the rough rake, late planting, impure variety, etc., while the seedling is not good There is also a certain relationship. Poor performance of seedlings as “not strong” “not old”, and “not strong” the most important. “Not old” and more due to the use of early rice to seedling, sowing later; “not strong” is not enough with the basic fertilizer, weeds more related. Therefore, through the application of basal fertilizer, as early as the top dressing, to promote fast seedling growth, inhibition of weeds thick, so as to achieve the purpose of strong seedlings worth noting.
