    摘要:

    为鉴别BJ2101-L保水剂不同施用方式对土壤水分和向日葵生长的影响效果,在内蒙古河套灌区以不施为对照,开展了沟施、混施和撒施BJ2101-L保水剂的田间试验。结果表明,沟施、混施和撒施均提高了0-80 cm土层土壤水分,特别是在向日葵开花期分别提高了10.71%,8.24%,6.63%。不同施用方式均促进了向日葵根系向深层土壤分布,促进了茎秆增高和增粗,提高了根、茎、叶、花盘生物量。沟施、混施、撒施籽粒产量分别较对照提高了26.80%,24.52%,10.86%,水分利用效率分别提高了49.29%,46.94%,25.06%,水分产出率分别提高了33.02%,29.79%,13.11%。河套灌区向日葵生产中BJ2101-L保水剂应以沟施或混施为主。

    Abstract:

    In order to determine the effects of BJ2101-L super absorbent with various application methods,field experiments were conducted to investigate their effects on soil moisture and sunflower growth in Hetao irrigation district,Inner Mongolia.BJ2101-L super absorbent was applied with three treatmets of furrowing,mixing and broadcasting.The results showed that three application methods increased soil moisture against the control(no application BJ2101-L super absorbent),particularly there were significant effects...
