论特色农业区域分布的气候条件——以葫芦河流域西芹产业带为例(英文)

Climatic Conditions of Regional Distribution of Characteristic Agriculture——With West Celery Industrial Belt in Huluhe Basin as an Example

[目的]研究葫芦河流域西芹产业带的气候条件。[方法]应用宁夏西吉县国家基本站1981～2010年气候资料,对葫芦河流域3个区域自动气象站近年作物生长期气象资料进行回归分析后,对西芹产业带气候条件用SPSS进行分层聚类分析。[结果]葫芦河流域西芹产业带划分为2个种植区:偏南部兴隆-硝河暖热多雨早熟区、偏北部吉强-新营温冷少雨晚熟区,4个亚区:兴隆暖热早产、硝河暖温偏早产、吉强冷温中产、新营冷凉晚产;每个种植亚区按气候层次结合生育期观测再聚类划分为5个不同阶段:积温播种期、低温出苗期、外叶适温生长期、心叶高温生长期、适时收获期。[结论]本研究对市场经济条件下西芹覆膜压沙种植采取不同播期、水肥方案、病虫害防治、上市时间等具有参考价值。

[Objective] The paper was to study the climate conditions of celery indus- trial belt in Huluhe Basin. [Method] Using the climate data of Xiji national basic sta- tion during 1981 and 2010, the meteorological data during crop growth period in 3 automatic weather stations along Huluhe Basin were carried out regression analysis, and the climate condition of west celery industrial belt was conducted hierarchical clustering analysis by SPSS. [Result] West celery industrial belt along Huluhe Basin could be divided into 2 growing regions： partially southern warm, rainy and early mature region, partially northern cold, rainless and late mature region. Years of practice proved that the small climate differences within 2 planting regions were more obvious, so these 2 planting regions could be further divided into 4 subre- glens： Xinglong warm, rainy and early mature subregion, Xiaohe thermal, rainy and partially early mature region, Jiqiang cool, rainless and middle mature subregion and Xinying cold, rainless and late mature subregion. [Conclusion] The study has refer- ence value for determination of different sowing time, different fertilizer and irrigation scheme, pests and diseased control and marketing time of west celery under mulch- sanded bunch plantation in market economic condition.
