我场位于广西北海市合浦县,有3000多亩柑桔。20多年的实践,使我们在柑桔矮、密、早、丰栽培措施上有深刻的体会。现仅就两个方面浅谈如下: 砧穗选择是关键。搞矮、密、早、丰栽培,成功的基础和关键是矮化。要做到矮化,措施很多,但最重要的是选择砧穗。砧穗的矮化效果不好,依靠以剪压梢、以果控冠这些办法,效果有限,最终还是果园严重郁闭,产量极低。根据我们的试验和大面积种植实践,选用枳和宫川温州密柑作砧穗,最适合建立矮化密植园,用酸桔和化州橙、尾张扁柑作砧穗矮化效果差。砧穗已定,种植密度必须与其适应。以枳作砧木的早熟温州密柑永久性果树,每亩以70～80株为宜。以 My field is located in Hepu County, Beihai City, Guangxi Province, more than 3,000 acres of citrus. More than 20 years of practice have given us a profound understanding of the measures for the cultivation of short, dense, early and abundant citrus fruits. Now just two aspects as follows: The choice of root scion is the key. Engage in short, dense, early, Feng cultivation, the basis of success and the key is dwarfism. To dwarf, a lot of measures, but the most important thing is to choose scion. Root dwarfing effect is not good, relying on the shear pressure tip, if the crown control of these methods, the effect is limited, and ultimately the orchard serious canopy closure, yield is very low. According to our experiments and large-scale planting practices, the use of Trifoliate orange and Miyagawa Wenzhou as the rootstock scion, the most suitable for the establishment of dwarf close planting, with orange and Huazhou orange, dwarf mandarin orange dwarfing effect as poor. Root scion has been set, planting density must be adapted to it. Trifoliate orange rootstock for the early maturing citrus permanent fruit trees, 70 to 80 strains per acre is appropriate. To
