结果表明，在不同生育时期3 g/L咸水处理对甜瓜产量均无显著影响，在开花坐果期和伸蔓期至果实成熟期，5，7，9 g/L咸水处理的单果重均极显著低于对照，而在果实发育期各咸水处理的单果重均显著低于对照；在甜瓜果实发育期以前，不同浓度咸水处理使甜瓜品质稍有降低，而后期处理则能提高甜瓜果实的品质，其中可溶性蛋白含量的变化不大；伸蔓期至果实成熟期持续咸水处理对甜瓜营养生长有明显的抑制作用，其中对株高的影响表现得尤为突出。

This was associated with the traits include eviscerated yield with giblet, breast muscle weight and eviscerated yield with giblet rate.

本次试验在23—54日龄肉鸡日粮中添加脂肪乳化剂—0.25%美肥和不同浓度的脂肪，并在日粮中添加脂肪乳化剂—0.05%唯乐美作为比较。结果表明：所选用的乳化剂可显著提高屠体重，半净膛率和全净膛率，降低腹脂率。同种脂肪浓度下，美肥添加组的屠宰率比未添加组高0.79~1.38%；美肥添加组的半净膛率比未添加组高1.30~2.62%；美肥添加组的全净膛率比未添加组高0.89~1.55%；美肥添加组的腹脂率比未添加组低0.20~1.88%；且其效果总体上优于唯乐美。

Among the three types of parent material,the yield of rape( above-ground dry weight) was the best(NPK treatment was the best in purplish soil ), Quaternary red soil and in granitization red soil were followed respectively(both of the two types of parent material have weak growth vigor and have a consistent yield). 2.With plant rape,NPK treatment could get more harvest among the three types of parent material , M treatment and CK were followed restectively.

结果表明：1、三种母质以紫色土油菜产量为最高（紫色土以NPK处理为最高），四纪红土次之，花岗岩油菜产量为最低（二种母质油菜生长均不好，产量差不多）。2、三种母质种植油菜均以NPK处理为最高。

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.
