早春低温引起烂秧,是我县水稻育秧中长期存在的一个大难题,每年因烂秧造成的种子损失13.5万公斤左右,严重年份达55万公斤以上。水稻育秧抗寒剂是具有稳定细胞膜结构功能的一种多成份抗寒剂。1992年早春由我县科委、农业局引进并试用于早稻育秧,取得较理想效果,现将试验结果报道如下: Low temperature in early spring caused by rotten seedling is my county rice seedling in the long-term existence of a major problem, each year due to rotten seed loss of 135,000 kilograms, a serious year of more than 550,000 kilograms. Rice seedling cold-resistant agent is a multi-component cold-resistant agent with stable cell membrane structure. Early spring 1992 by the county Science and Technology Commission, Bureau of Agriculture introduced and trial for early rice seedlings, achieved better results, the test results are reported as follows:
