摘　　要：1987～1990年,在山西省稷山县建立了20.7 ha板枣早实丰产试验林。采用“圆锥形”矮化栽培为主导的综合增产措施,结果表明:2年生板枣苗栽后第3年平均每公顷产鲜果878 kg(360株/ha)和3 113kg(1 245株/ha)。第4年,平均每公顷产鲜果1 940kg(360株/ha)和7 595 kg(1245株/ha),分别比对照提高3～8倍,投入产出比为1:7及1:13。早实丰产与树势、枝果比及叶绿素增加密切相关。The experimental plantation of 20.7 ha was established with seedlings of 2-year-old for research on early-bearing and high-yielding technique of Zizyphus jujuba in 1987 in Jishan County, Shanxi Province. The integrated measures (mainly conical brachysm cultivation) were applied. The results showed that the measures could remarkably increase the fruit yield. In the third year after planting, the mean yield of fresh fruit was 878 kg/ha in the plantation with a density of 360 trees/ha and 3113 kg/ha in the plantation with a density of 1245 trees/ha. In the fourth year after planting, the mean yield of the plantation with the density of 360 trees/ha, 1940 kg/ha, was 4 times over that of the control, and the mean yield of the plantation with the density of 1 245 trees/ha, 7 595 kg/ha, was 8 times over that of the control. The ratios of input to output were 1:7 and 1:13 respectively.
