营养膜无土栽培技术的研究

试验研究着重于设备、肥料和配方,产量效益、经济成本等。采用控制和调节pH值、电导度、氧气和设备等措施,使黄瓜亩产量达6861.5公斤;番茄因品种不同而有差异,早丰番茄品种达8361.1公斤。番茄每公斤成本0.29元。植物群体高大,根系发达,结果早,个体大,质量好。证明该技术操作容易,管理简单,产量高,有明显的经济效益。

A STUDY ON THE NUTRIENT FILM TECHNIQUE OF TOMATOES AND CUCUMBERS

The study is put emphasis on the equipment , fertilizer and nutrient solution, economic benefit of NFT. The tomato yield of early yield variety in NFT culture is 8361.1 kg per mu. The cost of tomato in one production season is 0.29 yuan per kg. The plants and roots in NFT are flourishing and bearing fruit is earlier. The tomato fruit are large and good quality. The study demonstrates easy manipulation, good yield and economic effects used NFT to culture the tomato and the cucumber.
