本文初步研究了膨大素对甘薯块根,茎叶生长的影响以及不同剂型膨大素单一处理,复合处理对甘薯的增产效果。结果表明:膨大素可以明显促进甘薯茎叶。块根的生长,提高单块薯重和单株薯重;不同剂型的膨大素都能使甘薯产量明显提高,复合处理的增产效果更好。 In this paper, preliminary study of the effect of bulking elements on the growth of tuberous roots and stems and leaves of sweet potato, and the effects of single agent and bulking agent of different dosage forms on the yield increase of sweet potato were preliminarily studied. The results showed that enlarged bulbs can significantly promote sweet potato stems and leaves. The growth of roots and tubers increased the weight of single potato and the weight of single potato. The results showed that the yield of sweet potato increased obviously with different dosage forms of bulking elements, and the yield increase of composite treatment was better.
