Sandalwood Seedling Container Weight Matrix Proportion Of Technology Reseach And Application

This paper uses L9 (34) growth light matrix optimal ratio of orthogonal test method of Santalum album seedlings. The light medium coconut chaff, peat soil,yellow soil of 3 factors, each factor selected 3 levels, a total of 9 treatmentswere set, Santalum album seedling experiment of container, Santalum album seedlingground diameter, height and leaf area of 3 growth indexes were measured.The results show that:(1) In light of different substrate compositions on Santalum album seedling ground diameter, Miao Gao and leaf area growth effects. Observation on the growth of Santalum album seedlings in container period (April 30th to August 30th), the dynamic change of container seedling growth of Santalum album ground diameter,seedling height and leaf area were relatively consistent. Early growth stage(before May 30th), different light matrix coconut chaff, peat soil and yellow soiltreatment, changes in seedling diameter, seedling height and leaf area weresmall, of late, Santalum album seedling ground diameter, Miao Gao and leaf area were significantly increased, and after the test period (August 30th)experimental treatment, A2B2C1 (coconut chaff, peat soil, yellow soil=2:2:1) the most obvious manifestation, seedling growth was the best.(2) In a different light matrix ratio in the experiment, the optimal combination of Santalum album seedling ground diameter growth were A6B2C3 and A2B2C1 treatment, the growth of diameter mean values are 0.25cm, the growth rate of88%, which is the most suitable light matrix material proportion is coconut chaff, peat soil, yellow soil=6:2:3 and A2B2C1 processing times. Through orthogonal test and analysis show that, coconut husk and yellow soil is the main factor of Santalum album seedling ground diameter growth, and differentpeat soil treatment is a minor factor Santalum album seedling ground diameter growth.(3) The optimal weight matrix proportion of Santalum album seedlings height growth: coconut chaff, peat soil, yellow soil=2:2:1, seedling height growthaverage value is 35.5cm, a growth rate of 71.52%, while the other lightmedium formula effect. The main factors affecting the Santalum album seedlingheight growth is change of Huang Xintu matrix, and coconut coir and peat soil.(4) the dominant factors affecting the growth of Santalum album seedlings leaf area is the change in the Huang Xintu ratio. The optimal combination of Santalum album seedlings leaf area growth is A2B2C1. That is the most suitablelight matrix material proportion is coconut chaff, peat soil, yellow soil=2:2:1,leaf area growth averaging 49.49cm.(5) through the breeding cost accounting analysis, obtains the Santalum album light matrix (coconut chaff, peat soil, yellow soil=2:2:1)seedling growth andseedling not only obvious advantages, low cost, light weight, should bepopularized in production.
