摘要
研究了３种高效复合液肥配合缩节安叶面喷施对高产棉田的生理效应和增产效果。结果表明，绿丰宝＋缩节安的效果最好，能明显增强根系活力，提高主茎叶的叶绿素含量和光合速率，单株结铃数比对照提高３３．８９％，增产４０．０６％，比单喷缩节安提高２１．３５％，增产２２．７７％；高美施＋缩节安的增产效果居第２位。
The physiological and yield-increasing effects of three kinds of highly efficient liquidfertilzers and DPC on high-yield eotton field by spraying on leaves were studied.The resultsShowed that LFB×DPC had the best effect,enhancing significantly rcot vigor,increasing theamount of chlorohyll of main stem leaves and photosynthetic rate.LFB×DPC had increasedthe number of bolling by 33.89%compared with CK and by 21.35%compared with only us-ing DPC,the yield increased by 40.06%compared with CK and by 22.77%compared withonly using DPC.The yield-increasing effect of GMS×DPC was the second.
