水稻育秧抗寒剂是中国科学院植物研究所研制成功的。承德地区农科所引进在水稻育秧上用于浸种,经多点试验,取得了良好的效果。一是能防止或减少水稻烂秧,提高成秧率。1992年承德地区水稻烂秧较重,发生率轻者达14—15%,重者整个苗床全毁;而经抗寒剂浸种的烂秧率在1.3%以下,成秧率在90%以上。二是提高了秧苗质量。用抗寒剂浸种的秧苗远看绿色明显比对照(水浸种)深,苗
Rice seedling cold agent is the Institute of Botany, Chinese Academy of Sciences successfully developed. Chengde area of agricultural introduction of rice seedlings for seed soaking, the multi-point test, and achieved good results. First, to prevent or reduce rotten rice seedlings, raising seedling rate. 1992 Chengde area heavier rotten rice seedlings, the incidence of light of up to 14-15% of light weight, the whole seedbed was destroyed; and soaked by cold agent soaked seedling rate of 1.3% or less, into the seedling rate of 90%. The second is to improve the quality of seedlings. Seedlings soaked with cold-resistant agents far see the green significantly (control) (water soaked species) deep, seedlings
