早酥梨栽植密度试验初报

对早酥梨采用不同密度进行栽植试验，结果表明：５年生前，各密度间单株产量差异不显著，而单位面积产量差异显著。每６６７ｍ２定植１６６株，５年生单位面积产量可达３３３５ｋｇ，比定植４２株提高１９８０ｋｇ。密植栽培，是早酥梨获得早期丰产的重要措施。

Rreliminary reportage on experiment of cultivated density of Zaosu pear

The experiment has proved that the difference of individual tree yield before fiveyear-old Zaosu pear was not significant among the different planting density, but the difference ofyield per area was significant. Planted 166 trees per 667 m2, the yield reach 3 335 kg at five-year-old, and it increased 1980 kg more than planted 42 trees per 667m. Planting densely was animportant measure by which the early high yield Zaosu pear may be obtained.
