- 摘要:
- 利用自行研制的大豆化控种衣剂和化控叶喷剂, 在大豆播种时进行化控种衣剂处理的基础上, 分别进行花期、鼓粒期及花期+鼓粒期叶喷处理, 研究了化控调节对大豆生育及产量的影响, 结果表明:生育前期化控植株明显矮化, 茎粗和根冠比增加, 尤其对根冠比作用明显, 平均比对照增加31 %;中后期喷施化控剂有利光合作用的提高, 加快蒸腾速率, 并对大豆体内水分代谢具有一定的调节作用, 最终增加结荚数、荚粒数和粒重, 起到保花保荚作用。不同化控组合增产幅度差异较大,以种衣剂+花期叶喷+鼓粒期叶喷全程化控增产幅度最高, 比对照增产23 .0 %。其次为种衣剂+鼓粒期叶喷处理, 比照增产20 .1 %, 而种衣剂+花期叶喷处理和种衣剂单独处理, 比对照增产分别增产12 .7 %和10 .2 %。
- Abstract:
- Influences of seed coating foliav agent made by us on soybean devaloping and grain yields were studied in thetest .The results indicated that seed coating significantly inhibited seedling height at early vegetative stage , enhancedstem thickness and root/shoot ratio , particularly the later increased 30 % compared with control .Application of foliar agentat later stage increased photosynthesis , sped up evaporation rate and better regulated water metabolism in the plants ,which , resulted in the increase of pod numbers , seeds per pod and seed size .The results also showed that the soybeanyield in the treatment of opplying seed coating and foliar agent at flowering and seed filing stage in creased 23 .0 %, ofapplying seed coating and foliar agent at seed filling stage increaed 20 .1 %, of applying seed coating and foliat agent otflowering stage , and applying seed coating alone increased 12 .7 % and 10 .2 % respectively than control .
