不同比例松针基质对凤梨生长发育及产品质量的影响

Effect of Different Proportion of Pine Needles Matrix Formulation on Product Quality and Growth of Ornamental Pineapple

研究了松针、泥炭4种不同比例基质配方对平红观赏凤梨生长发育、产品质量的影响。结果表明,全松针、1/2松针、2/3松针基质对凤梨的枯尖叶数以及枯尖长度都产生了显著影响,从而影响了观赏凤梨的产品质量;掺入1/3松针基质的凤梨枯尖叶数最少,枯尖长度短,对凤梨生长发育、产品质量影响不显著,可以替代部分泥炭。

The effect of four kinds of different proportion of matrix formulation of pine needles and peat on growth and development and product quality of Pinghong pineapple was studied. The results showed that the whole pine needles, 1/2 pine needles, 2/3 pine needles matrix had a significant impact on pineapple leaf blight tip number and length, thus affecting the ornamental pineapple product quality. The dry tip length of the matrix which mixed 1/3 pine needles shorted, was only 0.4 cm. Chlorophyll content had no significant difference between groups, so the incorporation of a matrix of 1/3 pine needles had no significant effect on pineapple growth and development, product quality, which could replace part of peat as an ornamental pineapple cultivation culture media.
