通过田间生产试验研究不同配比施肥对广西野生毛葡萄“野酿1号”“野酿2号”不同品种石漠化种植产量和品质的影响。结果表明,广西罗城县毛葡萄石漠化生产种植区土壤普遍缺钾,是影响毛葡萄健康生长的一个突出问题;毛葡萄对钾的需求量超过氮、磷,幼果至果实膨大期钾的供应特别重要,全年施肥N∶P2O5∶K2O=1∶5.1∶3.4,比N∶P2O5∶K2O=1∶0.6∶0.6有利于提高植株养分含量、增大叶面积,处理Ⅰ与Ⅱ、处理Ⅲ与Ⅳ相比产量分别增加29.9%和58.5%,总糖含量分别增加1.23g/100g和2.66g/100g,单宁含量分别增加3mg/100g和27mg/100g,可溶性固形物含量分别增加1.1和0.6个百分点,落果率分别降低6和1.2个百分点。
The field experiment was conducted to study the effects of different fertilization on the yield and quality of different desertified rocky planting grasses of Guangxi wild hairy grapes “wild stuffed 1 ” “wild stuffed 2 ”. The results showed that potassium deficiency in the soil of rocky desertification production area in Luocheng County of Guangxi Province was a prominent problem that affected the healthy growth of the grapevine. The demand for potassium in the grapevine was higher than that of nitrogen and phosphorus, Of the supply is particularly important throughout the year fertilization N: P2O5: K2O = 1: 5.1: 3.4, than N: P2O5: K2O = 1: 0.6: 0.6 conducive to improving plant nutrient content, increase leaf area, treatment Ⅰ and Ⅱ, treatment Compared with Ⅳ, the yield of Ⅲ increased by 29.9% and 58.5%, the total sugar content increased by 1.23g / 100g and 2.66g / 100g, the content of tannin increased by 3mg / 100g and 27mg / 100g respectively, the content of soluble solids increased by 1.1 and 0.6 percentage points, fruit drop rate decreased by 6 and 1.2 percentage points.
