葡萄的负载量与葡萄品质密切相关，一般而言，产量越高，葡萄所含的有效成分就越低，葡萄质量就越差，但产量也不是越低越好，每个品种都有其自身最佳的产量和质量比。本试验以赤霞珠、西拉、雷司令、琼瑶浆为试材，研究在怀来产区的气候和生产条件下，通过留芽量来控制负载量，探索产量和果实品质的关系。结果表明：留18个芽对酿酒葡萄产量及果实品质的影响最佳，产量、果粒情况、糖、酸、PH值等各项均处于中上等。
Grape load is closely related to grape quality. Generally speaking, the higher the yield, the lower the effective components contained in grapes and the worse the grape quality, but the lower the yield, the better. Each variety has its own best yield and quality ratio. In this experiment, Cabernet Sauvignon, Shiraz, Riesling and Qiongyao pulp were used as test materials. The load is controlled by the amount of buds retention to study the relationship between yield and fruit quality under the climate and production conditions of Huailai production area. The results showed that 18 buds had the best effect on the yield and fruit quality of wine grape, and the yield, fruit grain condition, sugar, acid and pH value were in the middle and upper grades.
