近年来在苏联阿塞拜疆各大葡萄园广泛采用微量元素做追肥。用作根外追肥的微量元素为:硼酸、硫酸锰、钼酸铵、硫酸锌与硫酸钴,其浓度各为0.01、0.05、0.1与0.2％。喷两次:开花前10～12天与浆果形成期。据试验所得到的材料及文献资料,可以得出以下结论: 1.施用微肥是改善葡萄植株营养状况,提高产量,改善品质的有效手段。 2.喷0.05％硼酸溶液对葡萄产量影响最大,比对照增产27.5担/公顷或29.5％。这是由于果
In recent years, the major Soviet Azerbaijan vineyard extensive use of trace elements for top-dressing. Trace elements used as top dressing were boric acid, manganese sulfate, ammonium molybdate, zinc sulfate and cobalt sulfate, with concentrations of 0.01, 0.05, 0.1 and 0.2% each. Spray twice: 10 to 12 days before flowering and berry formation period. According to the test materials and literature, we can draw the following conclusions: 1. Application of micronutrient fertilizer is to improve the nutritional status of grape plants, improve yield, improve the quality of effective means. Spraying 0.05% boric acid solution has the greatest impact on the grape yield, 27.5 dan / hectare or 29.5% more than the control. This is due to fruit
