通常来讲,水溶性复混肥配方更合理,养分更多元,对作物更有针对性。但生产中使用不合理,也会造成肥料的浪费甚至起负面作用。专家就水溶肥料的合理施用向读者提出建议。(一)根据灌溉设施选择肥料。衡量水溶肥质量的一个指标叫“水不溶物含量”。一般滴灌要求水不溶物小于0.2%,微喷灌水不溶物小于5%,喷灌水不溶物小于15%。淋施浇施要求相对更低。通常水不溶物含量越低,意味着肥料越贵。
In general, water-soluble compound fertilizer formula is more reasonable, more nutrients more, more targeted to the crop. However, the use of unreasonable production can also cause the waste of fertilizers or even negative effects. Experts advise the reader on the rational application of water-soluble fertilizer. (A) Choose fertilizer according to irrigation facilities. A measure of the quality of water-soluble fertilizer called “water-insoluble content ”. Generally, drip irrigation requires less than 0.2% of water insoluble matter, less than 5% of micro-sprinkler water insoluble matter and less than 15% of sprinkler water insoluble matter. Shower facilities require relatively lower. Normally, the lower the water-insoluble content, the more expensive the fertilizer.
