施用矿物源黄腐酸钾对黄瓜生长、产量及土壤的影响

Effects of Mineral Potassium Fulvate on Soil and the Growth,Yield of Cucumber

通过温室试验,研究了矿物源黄腐酸钾对黄瓜生长、产量及土壤的影响。结果表明:冲施不同浓度矿物源黄腐酸钾后,黄瓜生长指标及产量均有提高,综合对黄瓜各指标的影响,以冲施矿物源黄腐酸钾1.0 kg/667 m^2对黄瓜生长和产量促进作用最佳,增产率达11.8%;就土壤影响来看,冲施矿物源黄腐酸钾1.5 kg/667 m^2可以显著降低土壤容重。

Greenhouse experiments were used to testing the effects of mineral potassium fulvate on soil and the growth,yield of cucumber.The results showed that applying different concentration of mineral potassium fulvate could increase the growth indice and yield of cucumber.Considering the comprehensive effect on each index of cucumber,mineral potassium fulvate 1.0 kg/667 m^2 was the best concentration that consequently increased the yield by 11.8%.In terms of the impact on the soil,the application of mineral potassium fulvate 1.5 kg/667 m^2 could significantly reduce soil bulk density.
