叶面施肥对窄叶西南红山茶苗木生长的影响
Effect of Foliage Spray on the Growth of Camellia pitardii var.yunnanica Seedlings
摘要
Abstract
This test analyzed effect of different foliage spray mode on the growth of Camellia pitardii var.yunnan-ica Seedlings.Urea and potassium dihydrogen phosphate sprayed to Camellia pitardii var.yunnanica seedlings by a-dopted the two factors of exercise at three levels design on 27 plots by 2-way randomized block design in field experi-ment.The results showed that combined application of CO(NH2 )2 and KH2 PO4 in proper ration increased the height, ground diameter,crown breadth of Camellia pitardii var.yunnanica,and the effect was better than single application. Especially,the enhancement was remarkable in treatment 5 when spraying medium dose was 3 g/L of CO(NH2 )2 and 1 g/L of KH2 PO4 .Result of interactive analysis showed that it was the best for the height growth,reaching to 1.455 cm,when spraying dose of CO(NH2)2 and KH2PO4 were 2.718 g/L,1.654 g/L and its ratio was 1∶0.608.While dose of 2.499 g/L,1.569 g/L and ratio of 1∶0.628 was best for ground diameter growth,reaching to 0.068 cm. Therefore,we could adopt different formula fertilization according to the practical requirement.关键词
