近年在浙江黄岩桔区初结果的槾桔树上出现大量的黄斑叶、焦叶及严重的落叶现象,喷布钼酸铵500ppm液矫治效果极为显著。喷施钼酸铵不仅能消除黄斑,提高叶片质量,防止焦叶和落叶,还能促进新梢及根系生长,并有利于果实发育和外观内质的提高,对翌年着果率及产量的提高亦有明显效果。叶分析结果还表明,槾桔黄斑并非缺钼引起,而主要是高钠环境引起叶钠含量过高所致,喷钼酸铵后,叶片钠含量大幅度降低,从42.9ppm降至5.9ppm(无黄斑正常叶为4.6ppm)。
In recent years, Huangyan orange district in Zhejiang early results of the orange tree, there are a large number of yellow leaves, coke leaves and serious deciduous phenomenon, spraying ammonium molybdate 500ppm liquid correction effect is extremely significant. Spraying ammonium molybdate can not only eliminate macula, improve leaf quality, prevent scorching and deciduous leaves, but also promote new shoots and roots growth, and is conducive to fruit development and appearance of endoplasmic reticulum, the fruit yield and yield the following year Also have obvious effect. The results of the leaf analysis also showed that the macula was not caused by molybdenum deficiency, but mainly caused by the sodium content in the high sodium environment. After spraying ammonium molybdate, the sodium content in the leaves decreased significantly from 42.9ppm to 5.9ppm No macula normal leaves 4.6ppm).
