Rice potassium fertilizer should pay attention to what matters?

Since sufficient potassium is beneficial to enhance photosynthesis, promote sugar synthesis and accumulation, and increase plant resistance, it can also increase the respiration of rice roots, promote the absorption of nitrogen and protein synthesis, and make plants full and full, producing high yields and stable yields. Applying potassium fertilizer to rice can produce significant yield increase.

The following three points must be taken into account when applying potassium fertilizer. Potassium, which contains less potassium, is applied less, but it is less applied. High-stalk species are applied more, and dwarf species are less applied. Hybrid rice is applied more frequently and conventional varieties are less applied. Tests show that: Mushi 7.5 ~ 10 kg of potassium chloride, the most economic benefits.

Appropriate fertilization. Rice needs the most potassium in the period of high tillering and spikelet differentiation. Potassium fertilizer should be applied once, preferably during the tillering period. For two applications, it should be applied during the tillering period and the spikelet differentiation period.

With fertilizer. Potassium application must have the combination of phosphorus and nitrogen in order to fully exert its performance. Generally, the ratio of nitrogen, phosphorus and potassium is preferably 1:0.5:1.2.
