通过~(14)CO_2示踪及碳酸酐酶活性测定表明:在缺锌的石灰性土壤上,锌作为越冬青菜——上海四季青菜(Brassica Var Cammunis Tsen TT Lee.)的基肥,能提高青菜对 CO_2的同化量,增强碳酸酐酶的活性,提高茎叶、籽粒产量,并延长采食期。
The results of ~ (14) CO_2 tracing and carbonic anhydrase showed that zinc was the basic fertilizer of Chinese winter silage (Brassica Var Cammunis Tsen TT Lee.) On zinc-deficient calcareous soils, CO 2 assimilation, enhance the activity of carbonic anhydrase, increase stem and leaf, grain yield, and extend the feed intake.
