摘要
通过4种山楂初植密度与产量关系的试验,找出生产上既能获得早期丰产又能保持较长的结果周期的适宜的种植密度。结果表明,大面积推广应用以833株/hm2(3m×4m)的林分密度比较合理。为充分利用地力和获得单位面积最大收益,初植密度1666株/hm2(2m×3m),配以疏伐,最后达到833株/hm2(4m×3m)。
Based on the results of planting density experiments for
hawthorn,it was defined that for the high yield of hawthorn plantations the properstand density was
833 plants or 3m×4m per hectare.Therefore,the plantingdensity should be 1666 plants or 2m×
3m per hectare with the thinning toprovide the proper stand density,3m×4m.
