为探讨新型无土固态基质—炭棉在园林植物生产绿化应用上的可行性,本研究以传统基质(扦插基质、栽培基质)、进口无土固态基质—保浮科乐为对照,对4种基质物理性质进行测定,并对5种园林植物开展扦插育苗及年度生长对比试验。结果表明:炭棉容重、气水孔隙比与传统扦插基质均无显著差异,持水孔隙度显著高于“保浮科乐”;5种植物初始愈伤形成时间及生根时间在3种扦插基质中无显著差异;3种植物主根数及长度在2种固态基质中无显著差异;除金森女贞外,4种植物的生根率均高于95%;植物株高增长量和地上部干重增长量在传统栽培基质中表现最优,在2种固态基质中无显著差异;无土固态基质对植株地下部生长都表现出一定的控根作用。结合成本综合评价得出,新型无土固态基质—炭棉在植物生产上推广使用可行。
In order to explore the feasibility of a new type of soilless solid substrate - carbon cotton in the greening of garden plants, the traditional medium (cutting substrate, planting substrate) and imported soilless solid substrate - Matrix physical properties were measured, and five kinds of garden plants to carry out cutting propagation and annual growth comparison test. The results showed that there was no significant difference in bulk density, gas-water void ratio and traditional cutting matrix, and the water-holding porosity was significantly higher than that of “Bao Fu Ke Le”. The initial callus formation time and rooting time of the 5 species were in 3 There was no significant difference in the cutting medium. The main root number and length of the three kinds of plants had no significant difference in the two kinds of solid matrixes. The rooting rates of four kinds of plants were higher than 95% The dry weight increment showed the best performance in the traditional culture medium, and there was no significant difference in the two kinds of solid substrate. Soil-less solid substrate showed certain root control effect on the growth of the plant. Combining with the comprehensive evaluation of the cost, it is concluded that the new soilless solid matrix - carbon cotton is widely used in plant production.
