浙江省浦江县作物营养因子产生及效应分析

介绍如何使用TechnoGIN计算浙江省浦江县作物营养因子的方法,通过对这些因子进行分析知道,按目前农业水平,要实现对应的产量目标,投入同样的营养,同一作物在不同土地单元营养过剩量并不相同;同一土地单元不同作物营养过剩量也各不相同,经济作物比粮食作物的营养过剩相对较大,而旱作作物则表现为营养不足。不同作物不同土地利用类型的淋溶和气化量也可以使用TechnoGIN计算。因此可以说TechnoGIN是用来计算农业营养得失的一个有效的工具。它的结果对指导农业生产和进行环境保护有一定的参考价值。

Analysis of Efficiency and Crop Nutrition Factors in Pujiang County,Zhejiang Province

The article introduced how to use TechnoGIN to calculate crop nutrition coefficients.Through analysis,it could be seen: to realize yield target just like current agriculture level, the same crop in different land unit had different nourishment excess.The different farm crops in same land unit had different nourishment excess .The nourishment excess of the cash crop was more than food crop, but the nourishment of the drought crop was malnutrition. The number of the leaching and the vaporization of the crop in different land use type could be calculated also using TechnoGIN. So it could say: the TechnoGIN was a valid tool to calculate the agriculture nourishment gain and loss. Its result could be used to guide the agriculture produces and protect environment.
