abstract

The grain yield of rice with potassium fertilizer increased with the increase of potassium application rate, but the availability of potassium per kilogram increased, and then decreased with the increase of potassium application rate. Potassium exceeded a certain dosage range, but the yield decreased.

In this experiment, "Redmi" supplied by Guizhou partner Organic Agriculture Co., Ltd. was used as the material to compare the yield of different varieties of potash fertilizer. In order to further find out the economic and effective application method of potassium fertilizer to rice and its cultivation techniques in Redmi, give play to the best social benefits of Redmi, and provide scientific basis for verification, identification and popularization of rice varieties (lines), this experiment was conducted because of its high nitrogen tolerance and easy lodging. The experimental results show that under the same cultivation conditions and management, the highest yield of potassium fertilizer is 20 kg/mu, and its agronomic characters are good. It has good adaptability to climate and soil under medium natural conditions in Guizhou. This variety has strong growth potential, early maturity, good graininess and strong regeneration, so it can be considered for production and application in Guizhou.
