- 摘要:
- 以“新籽瓜1号”种子为试材,用4种不同梯度包衣浓度的2.5%咯菌腈悬浮种衣剂、37.5%萎锈灵+37.5%福美双悬浮种衣剂、6.25%精甲?咯菌腈悬浮种衣剂和35%丁硫克百威种子处理干粉剂处理“新籽瓜1号”种子,采用发芽盒法研究不同种衣剂处理对籽瓜发芽率及根长的影响。并采用盆栽试验及田间试验研究不同浓度药剂处理对籽瓜出苗率的影响。结果表明:4种药剂包衣后,若种子根部吸收了部分药剂会一定程度抑制根的伸长,但对于种子发芽率无显著影响。盆栽试验条件下,各浓度药剂处理种子后出苗率与对照无显著差异。而田间试验条件下,4种药剂按照商品推荐浓度处理种子后出苗率与对照无显著差异。综合各项试验结果,4种药剂在商品推荐浓度处理下具有较好的安全性,但是增大浓度处理后,尤其是在长期低温条件下可能存在一定风险。
- Abstract:
- Taking the seeds of new edible seed “Watermelon-1” as materials,four seed coating formulations include 2.5% fludioxonil flowable concentrate for seed coating formulations,37.5% carboxin and 37.5% thiram flowable concentrate for seed coating formulations,6.25% etalaxyl-M?fludioxonil flowable concentrate,35% carbosulfan DS were selected,the effect of different seed coating formulations to germination rate and root lenght of edible seed watermelon seed were compared in germinating box.The results showed that four seed coating formulations used in this research would inhibit elongation of root which absorb little seed coating formulation,but it had no significant difference to germination rate.Compared the effect of different seed coating formulations to emergence rate in pot and field experiment,the results showed that germination rate of seeds treating with four seed coating formulations has no significant difference compared with control in pot and field experiment.The experiments demostrated that four seed coating formulations used in this study had good security,but the increase of the concentration of treatment,the possible risk must exist in the long term under the condition of low temperature.
