| 摘 要： | 为探讨保水剂不同施用方式的应用效果，在河套灌区，以不施为对照，开展撒施、穴施、沟施和混施BJ2101L保水剂对土壤水分、盐分和番茄生长影响的田间试验。结果表明：1）沟施、穴施和混施均显著提高0～80cm土层土壤水分，特别在番茄坐果期较对照提高了12.66%、9.40%和7.50%；2）保水剂可有效抑制土壤盐分的积累，提高番茄幼苗成活率，沟施、穴施、混施和撒施番茄产量较对照提高了37.70%、30.93%、26.35%和12.87%，水分利用效率提高了56.58%、44.98%、32.58%和24.05%。因此，河套灌区番茄生产中保水剂应以沟施为主。 |

| 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,soil salinity and Lycopersicon esculentum growth in Hetao irrigation district,Inner Mongolia.In this paper,BJ2101-L super absorbent was applied with four treatments of furrowing,mixing,holing and broadcasting.The results showed that furrowing,holing,mixing significantly increased soil moisture in 0-80 cm soil layer,particularly there we... |
