摘　　要：通过砂培试验的方法，研究波尔多液营养保护荆BNPP—Fe、BNPP-Zn、BNPP—Fe—Zn和美国铜基杀菌剂Kocide矫治番茄缺铁黄化症和缺锌小叶症的效果，以及对番茄植株生长的影响。结果表明，与只喷清水的CK相比，喷施BNPP—Fe、BNPP—Zn、BNPP—Fe—Zn后，番茄叶绿素、活性铁、全铁及全锌含量都有显著提高，均能够矫治番茄缺铁、锌症状。同时喷施波尔多液营养保护剂后，番茄株高、茎粗明显优于CK，并且BNPP-Fe、BNPP—Zn、BNPP-Fe-Zn处理的产量比CK分别提高63.8％、27．6％～33．7％和129％～140％。BNPP—Fe—Zn处理与Kocide处理相比，番茄叶片全铁、活性铁和全锌含量差异显著，分别提高78，7％～104％、65．1％～173％和109％～142％，产量提高15．2％～22．8％。3种不同的波尔多液营养保护剂以BNPP-Fe—Zn效果最好，且优于美国Kocide产品。The tomatoes which were sensitive to iron and zinc were utilized to investigate the different effects of Bordeaux nutrition protective powder （BNPP-Fe,BNPP-Zn,BNPP-Fe-Zn） and Kocide on iron and zinc deficiency and growth of tomatoes by sandy culture method. The re, arch results indicated that because Bordeaux nutrition protective powders contained a number of soluble iron and zinc, chlorophyll content, active iron content, total iron content and total zinc content in leaves of tomatoes were increased differently by spraying BNPP-Fe ,BNPP-Zn,BNPP-Fe-Zn, compared with CK, in order to rectify iron and zinc deficiency. Meanwhile, the plant height and the stem diameter of tomatoes were hastened by spraying the three different Bordeaux nutrition protective powders, and the yield of tomatoes with BNPP-Fe,BNPP-Zn, BNPP-Fe-Zn treatments in- creased by 63.8% ,27.6% -33.7% and 129% --140%, respectively. In addition, Compared with Koeide, active iron content, total iron content and zinc content in leaves of tomatoes by spaying BNPP-Fe-Zn was significantly increased by 65.1% - 173 %, 78.7 % - 104 % and 109 % - 142 %, respectively. Moreover, The yield of tomatoes with BNPP-Fe-Zn treatment was increased by 15.2% --22.8%, but the yields of BNPP-Fe and BNPP Zn were less than that of Kocide treatment. As a result, the effect of BNPP-Fe-Zn was the best among the three different Bordeaux nutrition protective powders.
