人们认识到病毒导致柑桔矮化的价值已有相当时间了,但由于缺乏有关最适宜的距离报道,使发展受到阻碍。 1973年在澳大利亚、新南威尔士、阳可怖置了柑桔种植密度试验。这项试验把二个重要概念——矮化和高度密植放在一起来考虑。测定枳壳砧上的矮化和不矮化伏令夏橙栽距和产量之间的关系。行距2.0～5.0米,株距是1.0～3.0米。在矮化区第一年生产11～61吨/公顷,虽然矮化和不矮化柑桔之间,产量差异不一致,但12个处理中有9个处理未接种树的产量高于矮化树。在每株树的产量上全部差异少于5％,矮化接种和栽植密度两者都影响到树体大 It has been recognized for some time that the virus causes the dwarfing of citrus, but development has been hampered by the lack of coverage of the most appropriate distance. 1973 in Australia, New South Wales, Yang horrifying citrus planting density test. This experiment considers two important concepts - dwarfing and high density planting. The relationship between dwarfing and not dwarfing summer orange planting and production on Fructus Aurantia was studied. Row spacing of 2.0 to 5.0 meters, spacing is 1.0 to 3.0 meters. In the first year of the dwarfing zone, 11 to 61 tons per hectare were produced. Although there was no consistent yield difference between the dwarfed and the dwarfed citrus, the yield of 9 of the 12 treatments was higher than that of the dwarf tree . All differences in yield per tree were less than 5%, and both dwarfing and planting densities affected the tree size
