早春育秧遭受冷空气侵袭,常常发生严重的烂秧,使水稻生产受到很大的损失。这是大家共同关心研究解决的“老大难”问题。向来,在生产上防寒育秧多数采用长流水防寒、水播水育;覆盖暖性肥料、设防风障及熏烟,等等。毫无疑问,这些防寒育秧法都能够在一定的程度上克服恶劣天气的影响而收到较好的效果。为了进一步提高防止烂秧的成效,根据我区的育秧经验教训,拟定“低氮、高磷、高钾”抗寒育秧(简称“一低两高”育秧)。经过一些社队的初步实践,认为对抗寒、壮秧都有良好效果。
Early spring nursery seedlings were hit by cold air, often serious rotten seedlings, so that rice production suffered great losses. This is a common issue that everyone cares about studying and resolving. Has always been in the production of cold-blooming seedlings most of the long-term use of cold water, water sowing and education; covered by warm fertilizers, wind barriers and set up fumigation, and so on. There is no doubt that these cold-blooded seedlings are able to overcome the bad weather to a certain extent to receive better results. In order to further improve the effectiveness of preventing rotting seedlings, according to the experience and lessons of nursery seedling in our district, we plan to develop cold-tolerant seedlings with low nitrogen, high phosphorus and high potassium (referred to as “one low and two highs”). After the initial practice of some communes and brigades and teams, it is believed that the fight against cold and strong seedlings has good results.
