不同时期施基肥对葡萄生长及产量的影响

Effect of Base Fertilizer Applied in Different Periods on Growth and Yield of Grape

对葡萄春、秋不同时期施用基肥的效果进行了田间对比试验,结果表明,秋季与春季施基肥对葡萄植株的营养生长没有表现出差异,但在产量和浆果含糖量方面,秋施基肥略优于春施基肥。春施基肥可以节省劳动力,降低生产投入成本,在秋施基肥不便的情况下,可以考虑改为春季施肥。

The field experiments were conducted to compare the growth and yield difference between base fertilizer applied in spring and autumn. The results showed that there was no significant difference on nutritional growth of grape between base fertilizer applied in autumn and spring. While in the aspect of yield and sugar content compared with base fertilizer applied in autumn,it could save labor and decrease the production cost when base fertilizer applied in spring. When fertilizing is inconvenient in autumn the fertilizing in spring should be the best choice.
