Effects of Copper-Based Nutritional Foliar Fertilizers on Photosynthetic Characteristics, Yield, Quality and Disease Control Efficiency of Pepper
chlorophyll content and various indicators of photosynthetic characteristics of leaves
the plant and fruit total contents and accumulations of Cu
Zn and Fe
disease index of pepper and enzyme activities of soil were determined. The results showed that the CFFe
CFZnB
CF
and KCD significantly increased the photosynthetic rate
stomatal conductance
transpiration rate
and the chlorophyll content
in which the maximum increment was 20.13% by CFFe and followed by CFZnB that increased by 16.19%~18.13% as compared to the CK and significantly decreased intercellular CO2 concentration in pepper leaves. The BDM
KCD
CF
CFFe and CFZnB significantly increased the plant and fruit total contents and accumulations of Cu. The CFZnB
CFFe
CF
and KCD significantly increased the plant and fruit total contents and accumulations of Zn. The CFFe
CFZnB
CF and KCD significantly increased the plant and fruit total contents and accumulations of Fe. The CFFe
CFZnB
CF
KCD and BDM greatly reduced the disease index at the early fruiting and full fruiting periods of pepper. Soil urease activities of the CFFe and CFZnB were the highest. All treatments and CK significantly increased the soil catalase activities as compared to the BDM. The CFFe
CFZnB
CF
and KCD significantly increased the soil sucrase activities as compared to the CK. Pepper nutritional quality of CFFe was the best and followed by the CFZnB. The CFFe
CFZnB
CF
and KCD significantly increased the yield of pepper
with the CFFe maximally increased by 13.22% and followed by the CFZnB that increased by 11.93%~12.52% as compared to CK. The CFFe
CFZnB
and CF significantly increased the yield of pepper
the CFFe was the most and followed by the CFZnB. The CFFe
CFZnB
and CF significantly improved the quality of pepper
pepper nutritional quality of CFFe was the best
the second was the CFZnB. Copper-based nutritional foliar fertilizer developed by Shandong Agricultural University
as a kind of bactericidal and plant nutrition health care double functional foliar fertilizer
can significantly increase yield and improve the quality of pepper
and has certain effect on prevention and control of pepper disease. Therefore
iron-copper-based nutritional foliar fertilizer and zinc-boron-copper-based nutritional foliar fertilizer are recommended.
