摘要
在杭州湾慈溪滩涂盐渍土试验区块中,研究施加固体有机肥、绿化栽培介质、有机液肥和无有机肥等对盐渍土和绿化植物的影响。利用统一栽植20种植物模式的每个试验块(15m×20m),进行4个试验组,试验周期为18个月的研究。结果表明:施加有机肥能够降低和稳定表层土壤的pH值和含盐量,但未达到显著差异;3种有机肥均显著增加了土壤有机质含量,有机液肥的长期效果比绿化栽培介质和固体有机肥料差;施加有机肥料对20种植物的存活率、高度生长速率和径向生长速率等指标,改善效果,因植物种类存在较大差异;综合慈溪滩涂表层土壤理化性质和植物的变化情况,4个试验组改良效果大小为:绿化栽培介质≈固体有机肥料>有机液肥>无有机肥。
The effects of solid organic manure,green culture medium,liquid organic manure on coastal saline soil and garden plants were investigated in a beach saline soils experimental zone in Hangzhou Gulf（Cixi,Zhejiang,China）.4 field plots（15 m×20 m） with same planting pattern of 20 species of plants was treated with 4 different types of organic manure,Which were group B with solid organic manure,group C with Garden medium,group D with liquid organic manure and Group A,the control without organic manure.The experimental period was 18 weeks.The results indicated that the application of organic manure reduced pH and salt content of upper soil layer,but not significant.The three organic manures increased soil organic materials content significantly,but the long-term effects of garden medium and solid organic manure were better than the one of liquid organic manure.The effects of organic manure on the survival percentage,growth velocity of plant height and growth velocity of plant diameter of the selected 20 plants were very different due to the different plant species.The enhanced effects of the three organic manure on plants were as follows ：Garden medium≈Solid organic manure〉Liquid organic manure〉without organic manure.
