远红外波频仪在水稻生产中的应用效果OA
Application Effect of Far-Infrared Wave Frequency Meter in Rice Production
为探究远红外波频技术对水稻生长、产量及品质的影响,以龙粳31为供试水稻品种开展远红外波频技术在水稻生产上应用效果的研究.结果表明,2022年和2023年远红外波频处理的水稻平均分蘖率为210.70％,较对照高11.4个百分点;远红外波频处理的水稻平均株高分别为35.10 cm(分蘖期)、78.25 cm(孕穗期)、93.45 cm(齐穗期)、94.30 cm(成熟期),均高于同时期的对照;远红外波频的平均产量为621.7 kg·(667 m2)-1,较对照处理增产13.9 kg·(667 m2)-1,增产率达2.29％.远红外波频处理主要是通过远红外波频提高分蘖数继而提高有效穗数,增加水稻穗粒数和提高结实率获得增产.远红外波频处理水稻平均糙米率83.6％、平均精米率75.75％、平均整精米率75.60％,均高于对照;远红外波频处理水稻的平均直链淀粉为18.8％,略高于对照,远红外波频的平均食味值为81.0分,高于对照0.5分.远红外波频处理的土壤平均有机质为39.60 g·kg-1、平均碱解氮为136.25 mg·kg-1、平均有效磷为39.57 mg·kg-1,平均速效钾为127.56 mg·kg-1,均高于常规对照;远红外波频处理的土壤平均pH6.39,低于常规对照.因此,在水稻生产中利用远红外波频仪能够明显提高水稻产量、品质和土壤养分.
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 m2)-1,the yield increased by 13.9 kg·(667 m2)-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.
