Applied Studies on the Complexes of RE with Sulphur Contain-ing Organic Ligands Ⅱ: Potence of the Et_2NH_2CLa(S_2CNEt_2)_4 Complex Preventing Disease and Promoving Vegetable Growth

摘要

It has been studied that the Et_2NH_2[La(S_2CNEt_2)_4] complex prevents disease and promoves vegetable growth. The density of comples solution was 1‰. They were sprayed three times in all growth time. The results show that Vc and per mu yield of the test plant was increased and rate of their disease was decreased by 12 - 39 % compare with that of comparison(CK).
