茶叶是我国农业生产中的重要经济商品,目前还存在单产较低、品质波动较大的状况,原因是供给茶树养分比例失调。除氮、磷、钾比例不当,微量元素的匮乏也是重要的限制因子。我们试制的以微量元素为主体的茶叶专用叶面营养液,经与国外同类产品比较,达到了增产优质的目标。一、试验材料与方法 (一)供试肥料:茶叶叶面营养液Ⅰ号(上海农科院),茶叶叶面营养液Ⅱ号(上海农科院),世界专利产品CROP-UP(U.S.A) (二)供试品种:黄山大叶种、槠叶种。 (三)试验地点:皖南山区茶园,共十个点十三块试验田。
Tea is an important economic commodity in agricultural production in our country. At present, there is still a situation of low yield and great fluctuation of quality due to the imbalance of nutrients supplied to the tea tree. In addition to improper nitrogen, phosphorus and potassium ratio, the lack of trace elements is also an important limiting factor. We try to trace the elements as the main tea foliar nutrient solution, compared with similar foreign products, to achieve the goal of increasing production and quality. First, the test materials and methods (a) for the test fertilizer: tea foliar nutrient solution Ⅰ (Shanghai Academy of Agricultural Sciences), tea foliar nutrition solution Ⅱ (Shanghai Academy of Agricultural Sciences), the world’s patent product CROP-UP (B) test varieties: Huangshan large-leaved species, leaves species. (C) Test Location: Wannan mountain tea garden, a total of ten points 13 experimental fields.
