| 摘 要： | "美加富"是一种新型水稻健康理疗产品,具有抗逆防衰提高作物产量的效果。本试验采用中浙优1号、春优84、春江119、中浙A/恢5等4个水稻品种(组合),分别在移栽1周、分蘖盛期及齐穗期实施"美加富"叶面喷施。结果表明,喷施1000倍的"美加富"能显著增加水稻单株总粒数,使水稻产量提高6.0%~16.0%。"美加富"使水稻增产的主要原因是增加了水稻剑叶的叶绿素含量和光合速率,而对千粒重、结实率、株高、根系活力及品质均无显著影响。

| Abstract: | ＂Megafol＂ was classified as a plant therapy product. It is used to enhance the resistance of the plants to stress and increase crop yield. Four rice varieties as zhongzheyoul, chunyou84, chunjiang119 and zhongzheA/R5 were selected as materials. Foliage application was conducted at three stages： one week after transplanting, active tillering stage and full heading stage, respectively. The results indicated that ＂Megafol＂ increased rice yield by 6%-16% based on significantly increased the total fertile grain number per plant. Further study showed that the yield enhancement be derived from an increase of chlorophyll content and photosynthesis rate of flag leaves.＂Megafol＂ had no significant effects on 1000-grain weight, seed setting rate, plant height, roots system activity and rice cooking quality. |
