1976年1月间,以《提高秧苗质素,增强抗寒能力。——谈“低氮高磷高钾”抗寒育秧》为题,在《广东农业科学》谈了一些抗寒育秧的意见。1976年早造育秧季节,又对这方面的问题作了调查研究和试验分析。特别是1976年春季长期低温阴雨,对育秧威胁很大,有些地区还遭受严重烂秧,但不少社队采取控施氮肥,改进秧苗栽培管理方法,使烂秧减少到最低限度,进一步证明了“一低两高”育秧,是有一定的现实意义的。现将有关调查材料分述如下,供参考。早春天气与早造育秧的关系我区早春天气向来是不稳定的,民间曾有 January 1976, with “to improve the quality of seedlings, enhance the ability of cold. Talking about ”low nitrogen, high phosphorus, high potassium, cold hardy seedling“ as the title, and talked about some cold hardy seedlings in ”Guangdong Agricultural Sciences“. In early 1976, the season of planting seedlings was made, and the problems in this area were investigated and analyzed. In particular, the prolonged cold and rainy weather in the spring of 1976 has posed a great threat to the seedling raising. In some areas, it has also suffered serious rotting of seedlings. However, many communes have adopted measures to control the use of nitrogen fertilizers and improve the methods of seedling cultivation and management to minimize the rotting seedlings. This further proves ”A low two high" nursery, there is a certain practical significance. Now the survey materials are as follows for reference. Early spring weather and the relationship between early seedlings My area has always been unstable weather in early spring, folk have
