STUDIES ON THE EFFECTS OF STABLE MANURE, CHEMICAL FERTILIZER AND THEIR INTERACTION ON YIELD FORMATION OF SPRING WHEAT

WU Mei-yun~1, GAO Bing-de~1 (College of Ecology and Environmental Science,Inner Mongolia Agricultural University,Huhhot 010019 China)  
through field experiment in combination with indoor analysis,the experiments were carried out on yield and yield component factors of spring wheat in different treatment of fertilizer.The result were as follows the econornic yield,biological yield and economic coefficient of spring wheat were increased with applying stable manure,the average inereasing yield are 770kg/hm~2,1240kg/hm~2,4 peroent,and the number of kernels per ear was increased,the average increasing number was 4.2;In addition,NP and NPK fertilizer can also significantly increase the economic yield,biological yield and the number of kernels per ear of spring wheat,The interactive effect between sheep stale inanure and NP fertilizer was positive,but the interactive effect between stable manure and NPK fertilizer was different.
