保水剂施用方式对土壤水分及向日葵生长的影响
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)
