| 摘 要： | 板枣是我国枣树的名优品种之一。枣果营养丰富,经济价值高,既味美可口,又可入药,还是食品加工的重要原料,是我国一大特产。但因管理粗放,病虫较多,影响产量和质量的提高。在推广枣树增产技术措施中,虽以枣树开花期喷施赤霉素提高座果率效果较好,但目前赤霉素价格高,货源缺乏,严重影响了这一增产措施的实施。

| Abstract: | The comparison experiment of spraying 300 ppm rare earth solution, 15 ppm gibberellin solution and water on jujube (Zizyphus jujuba Mill.) during blossoming period was conducted in 1988 and 1989. As a result of the studies, the average yields per tree in the treatment sprayed with 300 ppm rare earth, 15 ppm gibberellin and water are 35.3kg, 28.2 kg and 18.5kg respectively. Rare earth can also improve the fruit quality. Sucrose and vitamin C content of the fruits in the treatment with 300 ppm rare earth is more than that in the treatment with 15 ppm gibberellin and water, sucrose and vitamin C content of the fruits in the treatment with 300 ppm rare earth, 15 ppm gibberellin and water are 8.842g/100g and 330.20 mg/100 g, 8.049 g/100g and 307. 92 mg/100 g, 8.078g/100g and 309.20 mg/100 g respectively. It is profitable to apply rare earth to jujube, the input to profit is approximately 1:62.3. |
