Research on the Yield and Characters of Maize in Different Controlled Release Fertilizer

This experiment researched the effects of the different controlled release fertilizer on the yield and characters of maize.The results showed that among the six types of CRFs (controlled release fertilizer),the first of all,total characters of CRFs Ⅴand CRFs Ⅵwere the best,the second were CRFs Ⅲ's and CRFs Ⅳ's.The application of CRFs in maize,not only can improve the yield characters of maize,but also can increase the yield of maize better.In comparison with common fertilizer,especially with the equal content of nutrition,to Zhengdan958,CRFs Ⅴand CRFs Ⅵincreased by13.5%,7.2%respectively,then CRFs Ⅲand CRFs Ⅳincreased by9.9%,5.1%;To Ludan50,CRFs Ⅲ,CRFs Ⅳ,CRFs Ⅴand CRFs Ⅵenhanced by0.5%,0.3%,8.1%,0.4%respectively.However the characters of CRFs Ⅰand CRFs Ⅱshowed bad and led to decrease the yield of maize.So CRFs Ⅰand CRFs Ⅱshould be given up.
