新型改良剂对盐碱地土壤性质和玉米生长的影响

The Effects of a Novel Soil Amendment on the Saline Alkali Soil Properties and the Growth of Maize Plants

为明确新型土壤盐碱地改良剂乙酰葡萄糖对山西省怀仁县的苏打盐碱地的改良效果,研究了施用不同剂量乙酰葡萄糖对盐碱地土壤性质和玉米生长的影响,为今后山西省盐碱地的改良提供理论依据。结果表明:土壤添加盐碱地改良剂后,土壤p H值、SAR、CO32-和HCO3-与对照相比都降低;土壤有机质、有效钾、苗期株高以及百粒重均增加。施用1500 kg·hm-2乙酰化葡萄糖可以有效改良盐碱地土壤,900 kg·hm-2乙酰化葡萄糖与猪粪和牛粪混合施用改良盐碱地可以达到更好的效果。因此,新型盐碱地土壤改良剂乙酰化葡萄糖是一种对山西苏打盐型盐碱地有效的改良剂。

The purpose of this study was to determine the effects of applying a novel saline-alkali soil amendment acetyl glucose in huairen county,Shanxi province. We analysised saline-alkali soil property and maize growth in response to different doses of acetyl glucose to provide a theoretical foundation for the improvement of the saline-alkali soil in Shanxi Province. The results showed that soil p H,SAR,CO3^2- and HCO3^- were reduced,the soil organic matter,available potassium,plant height and grain weight were significantly increased. The saline alkali soil could be effectively improved by adding 1500 kg·hm^-2 acetyl glucose per mu,and mixing the soil amendment（ 900 kg·hm^-2 acetyl glucose per mu） with pig manure,cow dung could improve the soil more effectively. So the acetyl glucose could be used as an effective saline-alkali soil amendment for Shanxi Province.
