Drip irrigation potassium fertilizer

Abstract

The invention discloses a drip irrigation potassium fertilizer. The drip irrigation potassium fertilizer is characterized by comprising a mixture of a potassium source, a magnesium source and a sulfur source, and the mixture contains the following ingredients in parts by weight: 50-60 parts of potassium source, 4-34 parts of magnesium source and 6-36 parts of sulfur source. According to the invention, the drip irrigation potassium fertilizer is directly applied to root systems and middle layers in a timely and appropriate manner and applied in a small-amount and frequent manner, so that the fertilizer application is timed and positioned, the crop absorption is facilitated, the loss is reduced, the fertilizer effect is fully played, and the soil can be improved; the fertilizer has good solubility, high dissolution rate and no impurity and is suitable for various drip irrigation devices; and the fertilizer efficiency is high, the yield / income increasing effect is obvious, and the fertilizer utilization ratio of drip irrigation under a film can be increased by 20%-30% compared with that of the conventional fertilizer application, so that the income increase is remarkable.

Description
