蔬菜施锌是农业部向全国推荐的1991年100项农业适用科技成果之一。山东济南市农科所和蔬菜局的科技人员从1981年开始在10多种蔬菜上进行的研究结果表明,在缺锌土壤上给蔬菜适量施用锌肥,不仅能显著增产,而且能提高其可食部分锌元素的含量。据研究,增施锌肥,可使番茄增产13.7％,黄瓜增产13％,白菜增产18.3％,甜椒、茄子、马铃薯、甘蓝、萝卜、绿豆、菠菜、芹菜等增产15.3％～30％。施锌后番茄、黄瓜每百克鲜重果实含锌量分别增加0.058和0.034毫克。另据动物试验,含锌高的蔬菜的补锌效果明显优于无机盐补锌。因此,蔬菜施锌是补充人体锌素营养的有效农业途径。锌是一种微量元素肥料,蔬菜合理施锌的关键是要适量,用量过大会使蔬菜内锌浓度过高,对人体健康产
Vegetable zinc application is one of 100 agricultural scientific and technological achievements recommended by the Ministry of Agriculture to the whole country in 1991. The results of a study conducted by more than 10 kinds of vegetables from 1981 onwards by scientific and technical personnel from Jinan Agricultural Bureau and Vegetable Bureau in Jinan City show that proper application of zinc fertilizer to vegetables in zinc-deficient soil can not only significantly increase yield, but also increase Food part of the zinc content. According to the research, increasing zinc fertilizer can increase the yield of tomato by 13.7%, cucumber by 13%, and the yield of cabbage by 18.3%. The yield of sweet pepper, eggplant, potato, cabbage, radish, mung bean, spinach and celery increased 15.3% ~ 30%. After applying zinc, tomato, cucumber per 100 grams of fresh fruit zinc content increased 0.058 and 0.034 mg. According to animal experiments, zinc-rich vegetables zinc significantly better than zinc supplements. Therefore, vegetable zinc is an effective agricultural way to supplement human zinc nutrition. Zinc is a trace element fertilizer, vegetables, zinc should be the key to a reasonable amount, the amount of excessive use of vegetables in the zinc concentration is too high, the health of human production
