The Effect Of Phyllitis Japonica Under The Different Culture And Nutritional

Phyllitis japonica, naturally distributing in Changbai mountain, had an excellent prospect of applying to greening in cold northern areas and to pot indoor for enjoying. In order to get the low cost, high quality soilless cultivation production and planting technology process for Phyllitis japonica, the research was conducted by choosing the culture substrates easily available in northeast areas and nutrient solution for soilless cultivation by means of single factor and combination method to probe into their different effect on Phyllitis japonica. It had a practical meaning for constructing a optimum technology process.Five matrix of Peatmoss soil, grain of sand, perlite, vermiculite and cinders, easily available in northeast areas, were matched by orthogonal test. The single test was conducted by using grain of sand, perlite, flowers mud (bakelite bubble) and vermiculite respectively for screening soilless cultivation matrix. The study on choosing nutrient solution were conducted with three foliage type nutrient sold well in market:Lvyiyuan foliage nutrient, Futeng foliage nutrient, Yaxing foliage and flower nutrient, and Heller,White and MS nutrients. Based on comparative study on morphological observation, determination of growth and relevant physiological indexes, comprehensive evaluation should be made to get cultivated matrix and nutrient appropriate to Phyllitis japonica. The results were as follows:1,The choice of cultivation matrixUnder the same environment of 70% Shading (118001x-456001x in the sunny noon), temperature from 5℃to 30℃, humidity from 30% to 80% and so on, the research result of single factor showed that vermiculite was the best. According to root biomass of Phyllitis japonica in different matrix, the matrix sorted in the following orders:vermiculite>perlite> grain of sand>flowers mud. The new leaves of Phyllitis japonica was the most cultivated in vermiculite, more than 50% over the perlite and grain of sand. The survival rate was the highest,1.19 times over the perlite and 2.99 times than grain of sand. By the survival rate, the matrix sorted in the following orders:vermiculite(50.0%)>perlite(42.8%)>grain of sand(16.7%)>flowers mud(0), the ck of soil (88.9%). The average leaves of Phyllitis japonica cultivated in vermiculite were 5, and its length was 15cm, which can satisfy the quality requirements about the production and ornamental cultivation.The study on cultivation of the mixed matrix showed that, sphagnum soil:pearlite: vermiculite:grain sand (7:1:1:1) and peatmoss soil:vermiculite:cinders (2:1:1) were best. The new growing leaves in the former group were 6, and in the latter one were 7. Its biomass reached the maximum in the group, the minimum growing leaves were 3. The average leaves of one flower were 8, the leaf reached a maximum length of 40cm. 2,The choice of nutrientsThe three nutrients of Lvyiyuan, Futeng and Yaxing could basically meet Phyllitis japonica's growth, and could be used as Phyllitis japonica's nutrients. The newly growing leaves in the three nutrients were all three, and the leaf area growth in Lvyiyuan foliage solution was 24.35 cm2,24.69 cm2in Futeng foliage solution,25.87 cm2 in Yaxing foliage and flower nutrients. But Phyllitis japonica were growing better in Yaxing than in Lvyiyuan and Futeng foliage nutrients. From September,2009, the content of soluble sugar of Phyllitis japonica cultivated in Yaxing was significantly lower than in the other two nutrients, only 60% in the other two nutrients. The three nutrients did not significantly influence on Phyllitis japonica, which could sustain Phyllitis japonica's ornamental periods of six months or more.In the three nutritional solutions of Heller, White and MS, only White could be as nutrients of soilless cultivation of Phyllitis japonica. Although the new buds could be got with White or Heller nutrients, the growth rate in Heller was lower than with White and there was not only no new buds with MS, but the plants withered slowly. The effectively ornamental periods of Phyllitis japonica with Heller were 60d, 100d with White and 40d with MS. In July, 2010, the content of MDA in Phyllitis japonica cultivated in MS was 30% more than in white and 120% more than in Heller. After 50d's cultivation,50% seedlings of Phyllitis japonica has vitality, with poorer ornamental effect. In White nutrients, the Phyllitis japonica were thriving, with better ornamental effect, which could meet the requirements of cultivation and application.3,It could conclude that vermiculite was the optimum matrix for Phyllitis japonica of soilless cultivation, pouring White nutrient or a regular nutrient every 7d with 200ml of dipping or dripping. Phyllitis japonica could leave enjoyment all the year in a good condition, sprayed every day.
