种子处理对西瓜出苗率和幼苗长势的影响

摘要

为了比较在实际西瓜种植户育苗条件下，种子处理对西瓜出苗率和幼苗长势的影响，分别选取北京顺义和大兴地区的4个育苗温室，对西瓜种子进行浸种处理并评估处理效果。结果表明：温汤浸种和药剂多菌灵、普力克、亮盾浸种均提高了出苗率；同时多菌灵和普力克处理对幼苗鲜质量和整齐度有所提高；只有试验点4未处理的种子发生苗期猝倒（5%），而浸种处理种子没有发病。种子处理能够提高出苗率和幼苗长势，然而催芽或土壤处理可能会影响浸种处理的效果。%In order to compare the effect of seed treatments on watermelon seedling emergence and growth under grower condition,four nursery greenhouses in Shunyi and Daxing of Beijing were chosen for evaluation of seed treatment. The results indicated that seed soaking in warm water,and chemicals including Carbendazim,Previcurn,MaximXL,increased seedling emergence;meanwhile Carbendazim and Previcurn improved seedling fresh weight and uniformity. Only the untreated seed in experiment location 4 had damping off seedlings(5%),while no disease occurred in seedlings from treated seed. In general,seed treatment improved seedling emergence and growth. However,seed pre-germination and soil treatment may influence the effect of seed soaking treatment.
