摘要
为促进亚磷酸钾在农业生产中的合理应用,以番茄为供试作物,通过小区试验,研究了不同浓度亚磷酸钾对番茄生长、产量和品质的影响。结果表明:与对照相比,亚磷酸钾占肥料重量比为3%~6%时,番茄各时期叶片SPAD值、中后期株高、产量和品质都有显著提高,茎粗没有显著差异;亚磷酸钾重量占比大于6%时,番茄各生长指标均随亚磷酸钾浓度的升高而降低。表明在一定浓度范围内亚磷酸钾有助于番茄生长、产量和品质的提升,具有使用价值。
In order to promote the rational application of potassium phosphite in agricultural production,the effects of different potassium phosphite concentration on tomato growth,yield and quality were studied with field culture tomato as subject crop.The results showed that tomato leaves SPAD value,plant height,yield and quality all increased significantly with potassium phosphite concentration between 3%-6%,while tomato stem diameter was not in statistically difference.However,when potassium phosphite concentration exceed 6%,all tomato growth indicators decreased with the increasing potassium phosphite concentration.Therefore,potassium phosphite at low concentration could improve tomato growth,yield,quality,and has good application value.
