摘要: 对影响小麦分蘖成穗、穗粒数、千粒重的12个气候要素,有代表性的8个地点进行模糊聚类分析,当选取λ值为0.857时,将河南省小麦气候生态聚为四个类区,即豫南、豫北、豫中北、豫中南;并对各气候生态区的小麦品种布局原则,生育特点及进一步提高产量的关键措施作了概述。

Abstract: Twelve climatic factors affecting wheat productive tillering rate, kernel number per spike, thousand-grain weight at 8 typical sits were caculated and analysed by fuzzy clustering method.Henan province was divided into four parts when λ= 0.857,they were south of Yu (Yu is short name for Henan), north of Yu, middlenorth of Yu and middlesouth of Yu.The distributive principles of wheat varieties and characteristics of growth and the main measures of harvesting higher wheat yield in their climatic ecological regions were discussed on the results.

Key words: Wheat, Fuzzy clustering method, Climatic ecological division, Henan province
