Research on Fertilizer Saving and Balanced Fertilization Technologies of Maize Production in the Southeast Liaoning Ecological Region
摘要
Abstract
In the Southeast Liaoning Ecological Region Fengcheng,Haicheng and Wa Fangdian,we studied the fertilizer saving and balanced fertilization technologies of maize production with a field experiment from 2014 to 2016. The results showed that,reducing the amount of application of chemical fertilizer,the growth of maize was promoted by compound fertilization (N-P-K = 23-10-22)and controlled release fertilizer (N-P-K =26-12-13). The average yield was 10978. 20 kg / hm2 and 10690. 65 kg / hm2 ,but there were no significant differences among compound fertilization (N-P-K = 23-10-22)and controlled release fertilizer (N-P-K = 26-12-13)treatments. The lowest lodging percentage was 3. 04% among compound fertilization (N-P-K = 23-10-22)treatments. The activities of protective enzyme,soluble protein and photosynthetic rates were higher than other treatments. This will provide theoretic and practice guide for fertilizer saving and balanced rational fertili-zation for spring maize in the southeast Liaoning ecological region.关键词
