云南西庄河流域具有发展粮食和经济作物生产的良好条件。主要粮食作物是小麦、玉米、水稻、杂粮 (苦荞、黍 ) ,主要经济作物是茶及桑树。由于作物生长具有复杂的生物物理机制和生物化学变化过程 ,不同作物对气候条件如光、热、水的需求是有差异的。为了监测西庄河流域气候特征 ,特地在流域中部设立了一个观测站 ,获得了该流域的主要气象要素特征值 ,使主要栽培作物的农业气候资源分析成为可能。本文对西庄河流域的农业气候特点及其对主要栽培作物的影响进行了分析 ,并进一步提出 :西庄河流域属于水稻、桑、烟叶分布区 ;玉米、苦荞、黍分布适宜区 ;小麦、茶生态分布最适宜区
Xizhuang River Basin in Yunnan Province has good conditions for developing food and cash crops. The main food crops are wheat, corn, rice, miscellaneous grains (buckwheat, millet), the main cash crops are tea and mulberry. Due to the complex biophysical mechanisms and biochemical changes of crop growth, the demand of different crops for climatic conditions such as light, heat and water is different. In order to monitor the climate characteristics of Xizhuang River Basin, an observation station was set up specially in the middle part of the basin, and the eigenvalues of the main meteorological elements in the basin were obtained, which made it possible to analyze the agricultural climate resources of the main cultivated crops. This paper analyzed the agricultural climate characteristics and the impact on main cultivated crops in Xizhuang River Basin, and further proposed that: Xizhuang River Basin belongs to the distribution area of rice, mulberry and tobacco; suitable areas for distribution of corn, tartary buckwheat and millet; wheat and tea Ecological distribution of the most suitable area
