柑桔定植后,促进幼树营养生长,使之迅速扩大树冠,是柑桔早结丰产栽培的基础,特别是在矮化密植栽培中更具特殊意义。广汉县地处川西平原,气温偏低(年均温16.4℃),加之冬春干旱,对柑桔刚定植幼树的成活及其生长均为不利。为此,我们在以往试验的基础上,于1983—1984年进行了本试验。试材植株(1年生枳砧兴津温州蜜柑)于1983年9月中旬至10月上旬,按8—4×3尺的宽窄行(333株/
Citrus planting, to promote the sapling vegetative growth, so that the rapid expansion of canopy is the basis for early harvest high-yield citrus, especially in the dwarf and close planting more special significance. Guanghan County is located in western Sichuan Plain, the temperature is low (average annual temperature of 16.4 ℃), combined with winter and spring drought, the success of citrus young planting tree growth and its growth are unfavorable. For this reason, we conducted this experiment from 1983 to 1984 on the basis of previous experiments. Plant materials (1-year-old Citrus aurantium Satsuma Satsuma mandarin) in mid-September 1983 to early October, according to 8-4 × 3 feet wide and narrow line (333 /
