由于盆栽果树养分、水分有限、在生长旺盛期易出现小叶病、黄叶病、缩叶病等生理病害。对此,需及时补充微量元素,以免影响其发育和生长。一、配制微量元素液的成分和浓度分别是:硫酸亚铁、硫酸锌0.2—0.3％,硫酸铜0.3—0.4％,硼酸0.1％,硼砂0.02％,硫酸锰0.08—0.1％,钼酸钠、钼酸铵0.08—0.1％,硫酸钙0.2—0.3％,硫酸镁0.4—0.5％(以上按等量比例配制,重量为单位)。将以上各种元素(化工商店有售)同时倒入一个容器里,加水10％,搅拌均匀即可使用。以随
Due to potted fruit tree nutrients, water is limited, vigorous growth in the prone leaflet disease, leaf disease, leaf scrub and other physiological diseases. In this regard, the need to add trace elements, so as not to affect their development and growth. First, the preparation of trace element liquid composition and concentration are: ferrous sulfate, zinc sulfate 0.2-0.3%, 0.3-0.4% copper sulfate, boric acid 0.1%, 0.02% borax, manganese sulfate 0.08-0.1%, sodium molybdate, 0.08-0.1% of ammonium molybdate, 0.2-0.3% of calcium sulfate, and 0.4-0.5% of magnesium sulfate (all the above are prepared according to the same proportion by weight). The above elements (chemical store for sale) at the same time into a container, add water 10%, stir can be used. Follow
