通过对“田力宝微生物肥料”产品的主要特性进行测定,结果表明该产品的N、P、K养分含量很低,达不到普通化肥的养分含量要求,不能直接作为商品化肥使用。根据该产品企业标准规定,对其固氮特性所作的测定反应,用乙炔还原法可测得该产品有还原乙炔的能力,但生物活性很弱,只有该产品标准规定活性指标的约三分之一。试验未能检出该产品的解磷、解钾能力。在对重金属的检测中,发现Cd的含量超过该产品标准的规定,但未超过国家对类似物质农业应用所规定的控制指标。
The results showed that the N, P and K contents of this product were very low, which could not meet the nutrient requirements of common fertilizers and could not be used directly as commercial fertilizers. According to the provisions of the product standards for the enterprise, its determination of the nitrogen fixation reaction, acetylene reduction method can be measured with the ability of the product to reduce acetylene, but the biological activity is very weak, only the product standard about one third of the activity index . The test failed to detect the product of phosphorus, potassium capacity. In the detection of heavy metals, it was found that the content of Cd exceeded the standard of the product, but it did not exceed the control index set by the state for the agricultural use of similar substances.
