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...
