Application Effect of Far-Infrared Wave Frequency Meter in Rice Production

In order to investigate the effects of far-infrared wave frequency technology on the growth, yield and quality of rice, a study was conducted on the application effect of far-infrared wave frequency technology on rice Longjing 31. The results showed that in 2022 and 2023, the average tillering rate of far-infrared wave frequency treatment was 210.70%, which was 11.4 percentage points higher than the control. The average plant height of far-infrared wave frequency treatment was 35.10 cm（tillering stage）, 78.25 cm（booting stage）, 93.45 cm（full heading stage）, and 94.30 cm（mature stage）, which were all higher than the control at the same period. The average yield of far-infrared wave frequency treatment was 621.7 kg ·（667 m~2） ^-1, the yield increased by 13.9 kg ·（667 m~2） ^-1, with a yield increase rate of 2.29%. The far-infrared wave frequency technology is mainly used to increase the number of tillers through far-infrared wave frequency, thereby increasing the effective number of panicles, increasing the number of grains per panicle, and improving the grain setting rate of rice to achieve yield increase. The average brown rice rate, average polished rice rate, and average whole rice rate of far-infrared wave frequency were 83.6%, 75.75% and 75.60%, all higher than the control. The average amylose content of far-infrared wave frequency was 18.8%, slightly higher than the control. The average taste value of far-infrared wave frequency was 81.0 points, which was 0.5 points higher than the control. The soil organic matter content treated with far-infrared wave frequency technology was 39.60%, with an average alkaline nitrogen content of 136.25 mg · kg^-1, an average available phosphorus content of 39.57 mg · kg^-1, and an average available potassium content of 127.56 mg · kg^-1, all higher than the conventional control.The average pH6.39 of far-infrared wave frequency was lower than that of conventional control.Therefore, the use of far-infrared wave frequency meters in rice production can signifcantly improve rice yield, quality and soil nutrients.
