摘　　要：为了探明丸化型水稻种衣剂的理化性能,为水稻免耕直播栽培技术提供参考,用丸化型水稻种衣剂WHW-25包衣水稻种子,通过种衣剂的成膜、贮存试验和包衣种子的吸水率、水下萌发以及贮存等试验,研究丸化型水稻种衣剂WHW-25的理化性能,并与进口种衣剂适乐时进行比较。结果显示:丸化型水稻种衣剂成膜性、贮存性及丸衣透水性良好;丸化包衣种子在水下的发芽势、发芽率分别比未包衣的对照提高了36.3%和33.5%;贮存12个月,丸化包衣种子的发芽率比对照提高了35.6%;其综合效果优于对比试验所用的进口种衣剂。说明丸化型水稻种衣剂能显著促进水稻种子在水下的萌发、提高水稻种子的耐贮存性,其理化性能良好。To explore physical and chemical properties of rice seed-pelleting agent tor prowdmg reference for no-tillage and direct-seeding cultivation of flee, the physical and chemical properties of seed-pelleting agent WHW-25 were studied by means of experiments of film-forming and storage of seed-pelleting agent, and experiments of water absorption, underwater germination and storage of pelleted rice seed. Meanwhile its effects were compared with those of a export seed -coating agent. Results showed that, the seed-pelleting agent had good properties in film-forming, film uniform and water permeability. The germinant energy and germinant rate of the pelleted rice seed increased 36.3% and 33.5% compared with uncoated controls, respectively. After 12 months＇ storage, the germinant rate of the pelleted rice seed increased 35.6% compared with uncoated controls. The general effects of this seed pelleting agent were obviously better than those of the export agent used in this experiment. These results indicated that, the seed-pelleting agent could markedly promote seed germination underwater and improve safety storage of rice seed, its physical and chemical properties were good.
