2年田间试验结果表明,萄葡喷施磷钾、微肥和有机、无机营养液均能提高产量,促进早熟。浆果着色好,果粒大,可溶性固形物、总糖和Vc含量增加,总酸度下降。浆果风味好,商品价值高。其中尤以喷施有机、无机营养液的效果最佳。营养液中加入GA(赤霉素),萄葡产量虽有所下降,但其品质和早熟性均优于未加GA的其它处理。
The results of field experiment in 2 years showed that phosphorus and potassium spraying, micro-fertilizer and organic and inorganic nutrient solution could increase yield and promote early maturity. Berry coloring, large fruit, soluble solids, total sugar and Vc content increased, the total acidity decreased. Berry flavor is good, the value of the product is high. Especially spraying organic and inorganic nutrient solution best. GA (Gibberellin) was added into the nutrient solution, although the grape yield declined, but its quality and precocity were better than other treatments without GA.
