摘要: 通过盆栽试验比较了施用不同剂量的泥炭(0%、2%、5%、8%及10%)对风沙土改良的效果和对白菜生长及产量的影响。结果表明,泥炭能增强风沙土的持水能力,降低土壤的pH值,增加土壤中有机质、全氮、速效氮和速效磷等的含量;白菜根系长度、生物量、高生长和地上部分的生物量均有增加,其中8%泥炭处理为最佳,其根系长度、根鲜重、干重、高生长、地上部分鲜重、干重依次比对照增加71%、402%、464%、107%、847%和1001%;同时施用泥炭还有利于提高白菜干物质的积累及其品质.

Abstract: With pot experiment, the effects of adding peat on amelioration of aeolian sandy soil and growth of Chinese cabbage(Brassica pekinensis)were investigated. The peat addition was divided into five treatments: 0%(the control treatment), 2%, 5%, 8% and 10%. The results showed that the physical and chemical properties of aeolian sandy soil were improved after peat addition. Adding peat increased the water holding capacity of sandy soil, decreased the soil pH value, and increased the content of organic matter, total nitrogen, available nitrogen and available phosphorus of soil. Also, it obviously increased the root length and root biomass, plant height growth, and above ground biomass of Chinese cabbage. Among all the treatments, adding 8% peat was the best, root length, root fresh weight, root dry weight, height growth, above ground fresh weight and dry weight increased by 71%, 402%, 464%, 107%, 847%, and 1001% respectively, compared to the control treatment. Meanwhile, adding peat could be advantageous to the accumulation of dry substance and the quality of cabbage.
