摘要: 为了研究氮肥与有机肥配施对冬小麦群体的影响,揭示实现冬小麦高产的条件,试验分析了长期定位施肥条件对冬小麦的叶面积指数及受光态势的影响。结果表明:氮肥和有机肥的施用量越大,群体越繁茂,叶面积指数也就越大,而群体内部光照强度就会降低,表征群体受光态势的半消光深度与叶面积指数极显著负相关。叶面积指数与氮肥(N)和有机肥(M)施用量之间的关系:LAI=4.41×10-3N+5.93×10-5M+0.888,通过合理施肥可以创造出具有最适叶面积指数的冬小麦群体。

关键词: 长期定位施肥, 叶面积指数, 受光态势

Abstract: In order to study on the effect of combined nitrogen fertilizer and organic manure on the winter wheat,reveal realize the conditions of the winter wheat high yielding,analyzed effects of long-term fertilization on the leaf area index of the winter wheat and the light distribution.The results showed that:the bigger accumulation of the nitrogen fertilizer and organic manure,the more flourish of the winter wheat and the bigger of the leaf area index of the winter wheat,while the light distribution of inner group decreased,A negative correlation between the leaf area index and semi-extinction depth which characterized the light distribution.A relation between the leaf area index and accumulation of the nitrogen fertilizer(N)and organic manure(M):LAI=4.41×10-3N+5.93×10-5M+0.888 was given in this research,we can create out the winter wheat which have the best suitable leaf area index by rational application of fertilizer.

Key words: Long-term located fertilization, LAI, Light distribution
