On the basis of the minimum scale soil nutrient distribution generated randomly based on the given values of mean, standard deviation and related distance, or obtained by geostatistics analysis based on soil sampling data, the amount of fertilization, yield and fertilization use efficiency at different scales were calculated by related fertilizer models and yield models supported by geographical information system and computer simulation, then the simulation result was intuitively visualized by curve graphics and RGB primitive colors synthesized image and thematic maps.

系统通过随机数生成法或地统计分析法生成最小尺度条件下的土壤养分空间分布数据,以此为基础,采用GIS、计算机模拟技术模拟不同尺度的养分空间分布,并以肥料效应模型和产量模型计算不同尺度条件下的施肥量、产量和肥料利用效率,最后通过曲线图、三原色合成影像和GIS专题图实现形象直观地表达模拟结果。

The fertilizer is high-concentration and fluid in its development in international.

国际上肥料的发展趋势是高浓度、液体化,因此液体肥料具有广阔的发展前景。

In this study, a culture with bitter gourd seedlings (Momordica charantia L.) was conducted in a field (clay slate noncalcareous alluvial soil, Tsp2), located in Wanli, Miaoli. There kinds of composted animal manure (chicken compost, cattle compost, and cattle-hog compost) as well as chemical fertilizer were applied to different treatment plots to investigate and compare their effects on soil fertility and the growth, and on the quality of bitter gourd. One check treatment was also conducted.

本研究系采用设施栽培方式,以嫁接苦瓜苗为品种材料,在苗栗县苑里(黏板岩非石灰性冲积土,水汴头系,TSp2)试验田,分别施用三种不同资材经堆肥化过程而生成之禽畜粪堆肥(鸡粪堆肥、牛粪堆肥和牛猪粪肥),并与施用化学肥料及不施任何肥料的对照组处理比较之,以评估不同来源及组成的有机质肥料对土壤肥力与苦瓜生育及品质产量之影响。

Two other low input ways to improve the soil involve using manure or nitrogen and phosphorous as fertilizer.
