二氢卟吩铁浸种对水稻生长与增产效应研究OACSTPCD
Effect on Rice Growth and Yield Increase:Seed Soaking with Iron Chlorin Soluble Powder
为探明0.02%二氢卟吩铁可溶粉剂浸种后对水稻生长、产量的影响及使用剂量.以'南粳9108'为供试水稻品种,将水稻种子在不同浓度0.02%二氢卟吩铁SP浸种处理,以0.0016%28-表高芸苔素内酯AS和0.136%赤·吲乙·芸苔SP为对照药剂,清水浸种为空白.分别在水稻苗期、分蘖期和成熟期调查其生长状况,并在收获期测定产量.结果表明:0.02%二氢卟吩铁浸种不影响水稻发芽,但浓度升高会降低水稻出苗率;0.02%二氢卟吩铁浸种可提高水稻秧苗鲜重、根数及水稻分蘖率;0.02%二氢卟吩铁稀释15000～10000倍浸种能增加水稻穗长、实粒数,提高水稻产量.因此,采用0.02%二氢卟吩铁15000～10000倍液浸种,可促进水稻生长,提高水稻产量,水稻生产中可扩大示范应用.
To explore the effect of 0.02%chlorin iron SP on rice growth and yield after seed soaking and its dosage,the'Nanjing 9108'was used as experimental variety.Rice seeds were soaked in 0.02%chlorin iron SP at different concentrations.0.0016%,28(s)-homobrassinolide AS and 0.136%gibberellic acid·indoleacetic acid·brassinolide SP were used as control agents,and the seeds with water immersion as blank control.The rice growth status was investigated at seedling stage,tillering stage and maturity stage,respectively,and the yields were measured at harvest stage.The results showed as follows:seed soaking with 0.02%chlorin iron did not affect the germination of rice,but the emergence rate of rice decreased with the increase of chlorin iron concentration.Seed soaking with 0.02%chlorin iron increased the fresh weight,root number and tillering percentage of rice seedling.When 0.02%chlorin iron was diluted 15000-10000 times,it could increase the panicle length,the number of solid grains and improve the rice yield.Therefore,seed soaking with 0.02%chlorin iron 15000-10000 times solution can promote rice growth,improve rice yield.The demonstration application can be expanded in rice production.
