无土基质中包膜复合肥对烤烟生产的影响

为了研究无土基质中，包膜复合肥对烤烟生长的影响，以水冬瓜果油为新型包膜材料，生产包膜肥料，采用盆栽试验方法对烤烟生长进行了研究。结果表明：在无土基质环境条件下，施包膜复合肥的烟株生物量鲜重为657.8 g，施普通复合肥的烟株生物量鲜重为513.5 g，净增加148.3 g；每克包膜复合肥生产烤烟干物质量比普通复合肥高6.1 g。通过无土栽培试验证明，水冬瓜果油包膜复合肥具有良好的生产性。

Study on the Ratio of Utilization of Release of Fertilizer with the Coating Fertilizer Based on Soil-less Culture

In order to research influence of growth of the tobacco with coated compound fertilizer in soilless cultivation, with the new coating material as the Idesia polycarpa var. vestita oil and producing the coated-released-fertilizer, the method of pot cultivation experiment was used in the growth of tobacco. The result showed that the weight of fresh bio-mass of the tobacco was 657.8 g in coated-composite fertilizer and that was 513.5 g in composite fertilizer and that increased 148.3 g in soilless agriculture, the quality of dry matter of production of per gram. Coated compound fertilizer was up to 6.1 g higher than ordinary composite fertilizer. The proof was tested that the coated-composite fertilizer as coating material with Idesia polycarpa var. vestita oil was good production.
