施肥对沟叶结缕草生长及生理特性的影响
Effects of fertilizing on the manilagrass growth and physiological characteristics
摘要
Abstract
The present study demonstrated the optimal fertilizing strategy for normal growth of manilagrass in the long growth stage through the experiments of fertilization, analyzing the interaction of changing in mass growth, colour, density, uniformaity of lawn and the content of chlorophyll, malondialdehyde, catalase and other physiological factors of manilagrass. The results of manilagrass growth factors indicated, the colour score of urea was better than the compound fertilizer and liquid fertilizer with significant effect on turning green in the lawn. The liquid fertilizer could promoted lawn grow uniformly; and the density of accumulation of compound fertilizer was best among the three types of fertilizers, provided the necessary fertilizer for lawn normal grwth at later stage. The treatments of urea with concentration of 15 kg/667 m2 was the best for the highest chlorophyll content, bright green colour and flourishing; the treatment of liquid fertilizer (1 000 × ) improved the MDA (malondialdehyde) to 0. 189× 10~2μmol/g FW, recovering normal growth and alleviating the growth stress for short period; the treatment of compound fertilizer (25 kg/667 m2) effectively enhanced the activity of CAT (catalase) for long time.关键词
