波尔多液营养保护剂对花生黄化症的矫治及生长效应的影响

选用山东省花生主产区的代表性石灰性土壤，通过土培试验的方法，研究了3种不同形态铁的波尔多液营养保护剂BNPP-NFe、BNPP-EFe、BNPP-RFe和美国铜基杀菌剂Kocide 4种可湿性粉剂矫治花生缺铁黄化症，以及对花生生长效应的影响。结果表明，与CK(喷清水)相比，喷施BNPP-NFe后，花生叶绿素、活性铁、全铁含量都有显著提高，并且BNPP-NFe、BNPP-EFe和BNPP-RFe处理的产量比CK分别提高92％～115％、67％～98％以及90％～94％。BNPP-NFe处理与Kocide处理相比，花生叶片活性铁和全铁含量差异显著，分别提高77.12％～139%以及29.01％～120%，产量提高27.5％～37.6％。3种不同的波尔多液营养保护剂以BNPP-NFe效果最好，且优于美国Kocide产品。

Effect of Bordeaux nutrition protective powder on iron-deficiency chlorosis and biological activity of peanuts

The calcareous soil which was collected from main peanut cultivated areas in Shandong Province was utilized to investigate the different effects of Bordeaux nutrition protective powder(BNPP-NFe,BNPP-EFe,BNPP-RFe) and Kocide on iron-deficiency chlorosis and biological activity of peanuts.The research results indicated that chlorophyll content,active iron content and total iron content in young leaves of peanuts increased differently by spraying BNPP-NFe,compared with CK(the treatment which only sprayed water).Besides,the yield of peanuts with BNPP-NFe,BNPP-EFe and BNPP-RFe treatments increased from 92% to 115%,from 67% to 98% and from 90% to 94%,respectively,as compared to CK.In addition,compared with Kocide,active iron content and(total) iron content in young leaves of peanuts by spaying BNPP-NFe significantly increased from 77.12% to 139% and from 29.01% to 120%,respectively.Moreover,the yield of peanuts with BNPP-NFe treatment increased from 27.5% to 36.7%,but BNPP-EFe and BNPP-RFe had no significant difference,compared with Kocide.As a result,the effect of BNPP-NFe was the best among three(different) Bordeaux nutrition protective powders.
