在草莓花期喷施２００ｍ ｇ·Ｌ－ １的光呼吸抑制剂ＮａＨＳＯ３，经测试，草莓植株叶绿素含量增加，光合速率增强，比叶重提高，硝酸还原酶活性受抑制，单果重增加。草莓果实品质明显改善，可溶性总糖含量增加２１％ ，提早成熟４～７ 天，亩产量增加１２％ ． At the flowering stage of strawberry, the photorespiratory inhibitor NaHSO3 was sprayed at 200 m g · L -1. After tested, the chlorophyll content, photosynthetic rate, specific leaf weight and nitrate reductase activity of strawberry plants were increased and the weight of single fruit weight increased. Strawberry fruit quality improved significantly, the total soluble sugar content increased 21%, 4 ~ 7 days earlier maturity, increased 12% per mu.
