为探讨油菜种子包衣后对种子的发芽率、生育期、株高以及产量等性状的影响,在陕西鸿塬农业科技有限公司的支持下,安徽省肥东县石塘镇农业技术推广中心开展油菜种子包衣直播试验。通过采取裸种对照、包衣、三叶期喷施多效唑、三叶期和越冬期喷施多效唑4种处理进行试验分析,初步得出油菜生长过程中喷施多效唑,前期生长缓慢,后期生长加快;油菜种子包衣处理可能因种子细小,加之包衣技术有待进一步改进,其发芽率偏低。
In order to explore the effect of rapeseed seed coating on seed germination rate, growth period, plant height and yield, the agricultural technology promotion center of Shitang Town, Feidong County, Anhui Province was supported by Shaanxi Hongyuan Agricultural Science and Technology Co., Ltd. Rape seed coating direct seeding experiment The experiment was conducted by taking four kinds of treatments including naked control, coating, spraying three-leaf stage paclobutrazol, clover leaf stage and wintersweet spraying PP333. The results showed that paclobutrazol was sprayed during the growth of rapeseed. The early growth was slow and the later growth was accelerated ; Rapeseed seed coating treatment may be due to the small seeds, combined with the coating technology needs to be further improved, the germination rate is low.
