摘要
研究了种子引发结合杀菌剂包衣处理对西瓜种子萌发和幼苗素质的影响。结果表明:15℃低温条件下,硝酸钾引发处理效果最好;20℃条件下,硝酸钾引发处理与蛭石引发处理效果相同,均能显著提高西瓜种子活力。运用咯菌腈和嘧菌酯药剂混配包衣西瓜种子,对西瓜种子具有良好的消毒效果。对西瓜种子进行引发和杀菌剂包衣综合处理可以提高温室西瓜种子萌发特性,缩短平均出苗时间,提高出苗率和幼苗素质。
Effects of seed priming and fungicide coating on seed germination and seedling growth of watermelon were studied.The results showed that at 15℃low temperature potassium nitrate had the best seed priming effect,and at 20℃both potassium nitrate and vermiculite were about the same in seed priming effect,significantly improving the seed vigor.The coating with mixture of fludioxonil and azoxystrobin had a good disinfection effect on watermelon seeds.In greenhouse culture seed priming and fungicide coating could improve the watermelon seed germination traits,shorten the mean emergence time and enhance the seedling emergence rate and seedling quality.
