一、试验园在农五师农科所红地球示范园内进行,试验园地势平坦,光照充足,土壤肥力中等,为壤土,株行距0.8×3米的篱架,南北行向。二、不同浓度磷酸二氢钾、尿素溶液的喷施1、方法每10株为一小区,重复三次,随机排列,红地球葡萄浆果膨大始期,每隔10天用背负式喷雾器喷液至叶面湿润不滴水为度,设有0.3%磷酸二氢钾加0.1%尿素溶液、0.5%磷酸二氢钾加0.2%尿素溶液、0.7%磷酸二氢钾加0.3%尿素溶液、三种处理浓度,以喷等量清水为对照,整个生长期进行五次喷施。2、结果与分析一定浓度范围内,喷过肥的比不喷施的固形物和糖分含量均有所提高,其中
First, the experimental garden in five agricultural division of the Red Earth Demonstration Park, the test park flat, light enough, medium fertility, loam, spacing of 0.8 × 3 m row fence, north-south line. Second, the different concentrations of potassium dihydrogen phosphate, urea solution spray 1, method for each 10 strains of a plot, repeated three times, arranged randomly, the red globe grape berries inflated the beginning of every 10 days with a sprayer sprayer to the foliage Moisture does not drip for the degree, with 0.3% potassium dihydrogen phosphate plus 0.1% urea solution, 0.5% potassium dihydrogen phosphate plus 0.2% urea solution, 0.7% potassium dihydrogen phosphate plus 0.3% urea solution, three kinds of treatment concentrations Spray the same amount of water as a control, spraying five times throughout the growing season. 2, the results and analysis within a certain concentration range, spraying the fertilizer than non-spray solids and sugar content have increased, of which
