摘要
通过田间试验,研究了不同控释肥料对夏玉米产量及其产量性状的影响。结果表明,在所选的6种控释肥料中,其综合性状以控Ⅴ、控Ⅵ为最佳,其次是控Ⅲ、控Ⅳ。在玉米上施用,不仅能改善其产量性状,而且增产效果特别显著。与普通肥料相比,在相同养分含量下,对品种郑单958来说,控Ⅴ和控Ⅵ分别增产为13.5%和7.2%,控Ⅲ和控Ⅳ分别增产为9.9%和5.1%;对品种鲁单50来说,控Ⅲ、控Ⅳ、控Ⅴ和控Ⅵ分别增产0.5%、0.3%、8.1%和0.4%。而控Ⅰ和控Ⅱ则分别减产,应予以淘汰。
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.
