镇平县2024年玉米单产提升综合试验示范研究分析
Research and Analysis of Comprehensive Experimental Demonstration for Improving Maize Yield in Zhenping County in 2024
摘要
Abstract
Through comparative experiments on corn varieties,planting density,planting patterns,water and fertilizer supply,as well as demonstrations and analyses of precise regulation,it is advocated to appropriately increase the planting density within a certain range,specifically between 4,700 and 5,500 plants per hectare,to achieve the highest yield,optimal benefits,and lowest risk.As the planting density increases,costs rise,the incidence of pests and diseases becomes higher,the risk of lodging increases,and the input-output ratio decreases.The planting pattern results indicate that the wide-narrow row planting pattern is superior to the equal-row spacing pattern,mainly manifested in increased grain number per ear and higher yield.The results of water and fertilizer experiments show that the highest yield is obtained with four applications of top dressing.The integration of water and fertilizer significantly increases yield compared to not using this integration.关键词
