种植密度对决定菠萝产量起着重要的作用,高种植密度能提高每公项产量(Cha-dha等,1973;Norman,1978;Dass等,1978).种植密度不影响菠萝植株的营养生长(Mustaffa,1980).由于氮肥成本高,且对果实品质有不良影响,确定菠萝最适施氮量显得特别重要(Tay,1972;Singh等,1977).因此,进行本试验旨在探讨“Kew”菠萝的最佳种植密度和最适施氮量,达到高产优质.
Planting density plays an important role in determining the yield of pineapple, and high planting density increases yields per common project (Cha-dha et al., 1973; Norman, 1978; Dass et al., 1978) Planting density does not affect the vegetative growth of pineapple plants , 1980). Because of the high cost of nitrogen fertilizers and their adverse effects on the quality of the fruit, it is particularly important to determine the optimum nitrogen level for pineapples (Tay, 1972; Singh et al., 1977) The best planting density and the optimum amount of nitrogen to achieve high yield and quality.
