In this paper, through the research process of Iris germanica development into material accumulation of Cheng Zhonggan change, ceiling fertilizer characteristics and reasonable fertilization formula and in fact set, the goal is to for Iris germanica scientific fertilization, field management and seedlings to supply according to superstition, has the practical significance of guidance to give birth. This study with 6 different patterns of German Iris species as test materials, six kinds of separation is "Bloodstone", white and yellow "," Changchun yellow "and" white and blue "," immortal white ", are in the open field cultivation. The experiment was divided into two departments, the first Department of the 5 German Iris species of dry material accumulation and fertilizer absorption study characteristics, material accumulation and fertilizer absorption characteristics of dry discipline won two different young German iris, has carried on the analysis of coherence and made the German iris unfair fertilization period; the second sector through the process, "3414" incomplete orthogonal design plan of 2 different types of young German iris stop fertilization of nitrogen, phosphorus, and potassium on different ratio, obtained in the pot experiment under the premise of the development of the German iris is beneficial to nitrogen, phosphorus, potassium fertilizer, important research results are as follows: (1) 5 German Iris species of dry material accumulation studies: 5 total dry material accumulation of German Iris species are described as "S" curve; 5 species of Iris germanica in flowering before bud stage when dry Material accumulation speed. In the whole growth period of five species are in the developing stage of the nutrient dry material accumulation of most of the eve; growth period, five kinds of dry material accumulation order for: "daytime goose", "white and yellow", "white and blue", "" Changchun yellow "" Bloodstone ", the plant type and the corresponding discrepancy. (2) 5 German Iris species fertilizer absorption characteristic study: 5 kinds of nitrogen, phosphorus, and potassium accumulation situation is more complex, the main organs of the body of nitrogen, phosphorus, potassium accumulation of individual changes, however, total nitrogen, total phosphorus, total potassium accumulation situation is more disciplined, the 1 season blossom types nutrient accumulation and nutrient important on the spring flowering development period, the 2 quarter of the total nitrogen, total phosphorus, total potassium species blossom in the spring period, the accumulation of important nutrients in the development period and the autumn season, another difference between the 1 and 2 season blossom blossom season type species, total nitrogen, total phosphorus, total potassium in 5 a test for high order difference accumulation in Iris species, said: "the total nitrogen total phosphorus total potassium". (3) analysis of 5 species of Iris germanica dry matter accumulation and nitrogen, phosphorus, potassium accumulation of coherence: the process of SPSS17. Yellow iris 0 coherence analysis shows that five German Iris species tested kinds of dry material accumulation and the corresponding nitrogen, phosphorus and potassium nutrient accumulation of coherence have reached a very dominant coherent degree, and are expressed as N nutrition accumulation and dry material accumulation of the highest coherency and interpretation of nitrogen fertilizer on dry matter accumulation effect of the most significant; 5 German Iris species of nitrogen, phosphorus, potassium and dry material accumulation of coherence in the following order, "Bloodstone": n, P, K, white and yellow ": n, P, K," evergreen ": n, K, P, white and blue": n, K, P, "daytime goose": n, K, P. Separation is expressed that in the early period of the iris (4) 2 different flowering Iris germanica differences and nitrogen, phosphorus and potassium fertilization research: through the process of "3414" not complete orthogonal regression experimental analysis, invention, two potted Iris germanica nitrogenous fertilizer, phosphate fertilizer played an important role in the development of prometaphase, potash fertilizer played an important role in plant development, the four development goals for phosphate fertilizer, potash fertilizer; through the process of setting up a binary, binary, ternary quadratic fertilizer effect equation made every development goals under the optimum nitrogen, phosphorus and potassium fertilizers, initially through the process and the right to obtain the appropriate two German Iris species development of N, P, K fertilizer ratio 0. 10g. Kg 1, 0. 23g - kg 1, 0. 16g. Kg "1 and 0. 10g. Kg 1, 0. 27g - kg 1, 0. Kg - 19g 1. The nitrogen and phosphorus fertilizer was separated into: 1:2. 7:1. 9 and 1:2. 3:1. Six 目录: |
