山葡萄由野生变为家植,只有二十多年的历史,还有许多问题有待逐步研究解决。为了提高山葡萄的产量,提高座果率是其中主要的一环。在某些农作物和果树上,喷硼增产的成功经验国内外都有报导。据此,1976～1977两年我们在山葡萄开花期进行了喷硼提高座果率的试验,获得了良好的效果。 1976年,用0.1％和0.3％两种浓度的硼酸水溶液在盛花期行进喷布,以不喷硼作对照,每处理5个花序。结果是喷硼的两个处理,其座果率均比对照高一倍多(见表1) 喷硼的两个处理不但座果率显著提高,且果穗上浆果也比较整齐。 Mountain grapes from wild to home planting, only two decades of history, there are many problems to be studied step by step. In order to improve the yield of mountain grapes, fruit set rate is one of the major components. In some crops and fruit trees, the successful experience of spraying boron has been reported both at home and abroad. Accordingly, in the two years from 1976 to 1977, we conducted the test of spraying boron to increase the fruit set rate in the flowering stage of the mountain grape, and achieved good results. In 1976, with two concentrations of 0.1% and 0.3% boric acid aqueous solution at full bloom flowering, non-boron as a control, each treatment of 5 inflorescences. The result was two treatments of boron sprayed, whose fruit rate was more than double that of the control (see Table 1). The two treatments of spraying boron significantly improved the fruit set rate and the berries on the ear were more neat.
