佛山地区早春水稻育秧,常因遭受冷空气侵袭造成烂秧。为了增强秧苗抗寒能力,解决烂秧问题,除采用抗寒育种外,通过栽培技术,提高秧苗素质,也可增强抗寒能力,其中尤以施肥方法和肥料成分对秧苗素质有着重要影响。因此,秧田合理施肥是抗寒育秧成败的一项关键措施。根据我区育秧经验,拟定了“低氮、高磷、高钾”(简称“一低两高”)抗寒育秧,经过一些社队的初步实践,取得了良好效果。
Early spring rice growing in Foshan, often due to cold air invasion caused by rotten seedlings. In order to enhance the ability of cold-tolerant seedlings and solve the problem of rotten seedlings, in addition to using cold-resistant breeding, cultivation techniques can improve the quality of seedlings and enhance the ability of cold-resistance. Fertilizing methods and fertilizer compositions have an important influence on seedling quality. Therefore, the rational fertilization of seedling is a key measure of the success or failure of cold-curing seedlings. According to the experience of nursery seedlings in our district, we have formulated the cold-curing seedlings of “low nitrogen, high phosphorus and high potassium” (short for “one low and two highs”) and achieved good results through the initial practice of some communes and brigades.
