The biennial Spathiphyllum material, A pot experiment was carried out a systematic study on the the Spathiphyllum of soilless cultivation, is to identify the the Spathiphyllum soilless culture supporting technical measures, including lighting suitable for the growth of Spathiphyllum Method of use of temperature, humidity and other environmental conditions suitable for the cultivation substrate, nutrient solution and nutrient solution. The orthogonal design method to study the culture substrate ratio of nutrient solution, the concentration of the nutrient solution, nutrient solution application method and nutrient solution application interval five factors on target plants. Which in addition to the culture substrate to set the level of 6, other factors are set at three levels. Determination of photosynthetic rate and related ecological factors, and explore the growth and development of temperature, humidity and light conditions for Spathiphyllum; at the seedling stage, into a seedling and flowering early determination of plant height, leaf area, leaf number, net photosynthetic rate and chlorophyll content, growth and physiological indicators and indicators in order to identify suitable for the growth of Spathiphyllum at different stages of the best matrix formulation, the proportion of the nutrient solution and other cultivation measures analysis of variance, Spathiphyllum soilless culture theoretical basis and supporting science and technology measures. Measured with a Li-6400 portable photosynthesis system the Spathiphyllum seedling stage light compensation point and saturation point is 17.86μmol · m-2 · s-1 and 300 micromol · m-2 · s-1; Spathiphyllum most suitable for the growth The temperature is 26 ~ 29 ° C, humidity of 60 to 80%. In the winter to take the heated humidification facilities, with 30% shade net shade slightly in March to May, June to September in the summer to 70% shade nets and blower cooling and humidifying the need for timely watering. Into a seedling and early flowering, an appropriate increase in temperature and light, in early flowering water control, reduce air humidity, prompting Spathiphyllum early flowering. The results showed that the experimental soilless cultivation of the five factors taken affect of Spathiphyllum seedling stage of growth and physiological indicators were significant factors, 4:1 peat and perlite mixed matrix helps plant height, total leaf area, leaf increase in the number, N: P: K: Ca: Mg: S = a 8:1:3:2:1:1 the nutrient solution proportion combination, 2% of the mass fraction of the nutrient solution, fertilization pelvic floor to the liquid method, applied once every seven days fertilizers seedling growth and physiological indexes can reach the maximum. In Spathiphyllum seedling growth stage, the proportion of the selected peat and perlite mixed 2:1 matrix, the nutrient solution N: P: K: Ca: Mg: S = 10.5:1:4.5:1:1:1 good, quality scores 3 ‰, watering matrix method of application, an interval of 7 days fertilization can make of Spathiphyllum into seedling stage plant height, total leaf area, leaf number and net photosynthetic rate reaches the maximum. The soilless cultivation five factors Spathiphyllum flowering early growth physiological indicators have an impact. Available experimental matrix portfolio choice of a 2:1 mixture of peat and perlite matrix; the nutrient solution better to use the N: P: K: CA: Mg: S = 5.5:1.5:3.5:1.5:1:1 and 1 ‰ ~ 2% of the mass fraction of the nutrient solution, the use of the pelvic floor to the liquid method, application of fertilizer interval of 7 days, you can make Spathiphyllum flowering early growth and physiological indicators reached the maximum. Derived chlorophyll affect chlorophyll synthesis of the main factors is the culture medium, the concentration of the nutrient solution, nutrient solution application interval and nutrient solution application method. A mixture of peat and perlite 2:1 matrix, nutrient solution concentration to 2 ‰ quality scores, application of fertilizer interval of 15 days, the pelvic floor to the liquid method chlorophyll content. Spathiphyllum early flower and flower growth index results can be seen, the Spathiphyllum of early flowering, total leaf area is closely related to, the sooner treatment combination with the greater total leaf area in the early flowering, early flowering, indicating the growth of Spathiphyllum to a certain amount of growth before they begin to bloom, accelerate vegetative growth may promote Spathiphyllum early flowering. The use of nutrient solution, using this test, the ratio of the level 3: N: P: K: Ca: Mg: S = 5.5:1.5:3.5:1.5:1:1, Quality Score 2 ‰ watering matrix method. interval 15 day administered once fertilizer helps to improve the quality of Spathiphyllum pedicel bud.
