Effects Of Folia Fertilizer On Calendula Officinals L. Plug Seedlings' Growth And Its Physical And Biochemistry Characteristic

This paper used Calendula officinals L. plug seedlings as expetiment material. The ratio of plug media was: the volum of grass carbon: the volum of peanut shells: the volume of chichen dung=5:4:1. By L9(34) orthogonal layout, Nine kinds of defferient folia fertilizer combination were experimented on base of three levels of ureophil, potassium and micro-fertilizer. On 15, 25, 35 and 45d of seedlings age, C. officinals L. plug seedlings with nine areolas and two duplications were fertilizerd in order. After 10 days, each index marks were measured. Effects of foliar fertilizer on physiological and biochemistry Charateristic of C. officinals L. plug seedlings were discussed, which would supply making technique measurement of C. officinals L. factory seedlings with the testification of theory and practice.The results showed that plug media could supply C. officinals L. plug seedlings' normal growth during its growth with rich N fertilizer. If fertilizerd ureophil, Not only C. officinals L. plug seedlings were caused excessive growth of branches and leaves, but also root growth were inhibited significantly, RuBPcase of photosynthesis' critical enzyme and Catalase (CAT) protecting plants from H2O2 destroy were decresed significantly, which caused seedling index, Root/shoot ratio and net photosynthetic rate (Pn) decresed significantly.About 25 day of C. officinals L. plug seedlings age, Micro-fertilizer in plug media was not enough, 0.02% Micro-fertilizer were needed. Among eight index marks, Except Seedling index, Leaf dry weight, RuBPcase and Chlorophyll content, the order of three kinds of fertilizers' effects on other index marks was urophil, micro-fertilizer, potassium. The differentia of Pn affected by it was significant.About 35 day of C.a officinals L. plug seedlings' age, 0.1% potassium and 0.01% micro-fertilizer were needed, then seedlings could be able to grow normally. For Seedling index, root dry weight, leaf dry weight, root/shoot ratio, RuBPcase, chlorophyll content, the order of three kinds of fertilizers' effects on them was urophil, potassium, micro-fertilizer, other index marks is micro-fertilizer, urophil, potassium. The differentia of potassium and micro-fertilizer's effect on Pn and RuBPcase was significant.Besides, the results proved that there was interaction among three kinds offertilizers and correct ratio could better the conditions of seedlings growth.
