Abstract:
Taking ‘Jinyou 35’ cucumber cultivar as test material,the accumulation of Zn in soil,the absorption and transportation of Zn in cucumber and the distribution of Zn in subcellular fractions were studied after chicken manure application with different dosages (0,15,30,45 t·hm-2 and 60 t·hm-2),in order to provide a reference for safe production of cucumber and rational application of chicken manure.The results showed that lower application of chicken manure could significantly increase soil Zn content (P<0.05),and the highest Zn content was 140.40 mg·kg-1,which did not exceed the national safety standards.Application of 60 t·hm-2 chicken manure application significantly increased the Zn content in cucumber root and fruit.The range of Zn content in cucumber fruit ranged from 19.27 mg·kg-1 to 23.59 mg·kg-1,but the Zn content was not more than 100 mg·kg-1,which could be safely eaten.No matter the amount of chicken manure applied,Zn in cucumber roots,stems,leaves and fruits showed the following order,soluble component
