(1) can be used as base fertilizer.When using potassium sulfate as base fertilizer in dry land, it is necessary to apply deep covering soil to reduce the crystal fixation of potassium, and use crop root system to absorb and improve the utilization rate.
(2) for topdressing.Due to the low mobility of potassium in the soil, banded or acupoint application should be concentrated in the soil layer with dense root system to promote absorption.Sandy soil often lack of potassium, should be used as topdressing to avoid leaching.
(3) can be used as seed fertilizer and topdressing.It can also be prepared into 2% ~ 3% solution for topdressing.
