矿物类风沙土改良剂对小叶锦鸡儿生理特性和生长状况的影响

通过盆栽试验,并运用多元统计的方法分析矿物类改良剂Arkadolith对风沙土的改良效果以及对小叶锦鸡儿生理特性和生长状况的影响,结果表明:Arkadolith改良剂对风沙土理化性质的改良作用明显,表现为土壤容重、总孔隙度、pH值、EC值、>0.25 mm水稳性团聚体、全氮、有效磷、速效钾、有机质明显改善;促进了小叶锦鸡儿的生长,表现为小叶锦鸡儿的蒸腾速率、高生长和生物量明显优于对照,同时当风沙土中施入10%的Arkadolith改良剂时最有利于小叶锦鸡儿的生长。Arkadolith土壤改良剂作为一种新型矿物改良剂,改良土壤的作用更加长久、高效,并且更加安全、环保,同时更有利于植物生长。

Effects of Arkadolith Mineral Amendment to Physiological Characteristics and Growth of Caragana microphylla on Aeolian Sandy Soil

It analyzed the effects of Arkadolith amendment to the improvement of aeolian sandy soil and the physiological characteristics and growth of Caragana microphylla by multivariate statistical method through pot culture.The outcomes show that: a) the action of Arkadolith amendment to the chemical and physical properties of aeolian sandy soil are obvious and bulk density,total porosity,pH value,EC value,> 0.25 mm water-stable aggregate,total N,organic matter,available P and available K of soil are all improved greatly;b) it also promotes the growth of Caragana microphylla and the transpiration rate,high growth and biomass of Caragana microphylla are better than that of the checked and;c) at the same time,when putting 10% Arkadolith amendment into aeolian sandy soil,it is the best condition for Caragana microphylla growth.Being as a new type of mineral amendment,the function of the improvement of Arkadolith amendment for aeolian sandy soil is more efficient,secure and environmental and more advantageous to the growth of plants.
