采用田间小区试验,研究不同施肥结构和酸调理剂对由第四纪红土发育的酸性红菜园土的酸性、有效养分以及作物产量的影响。结果表明:不同施肥处理间的土壤碱解氮含量差异有统计学意义,辣椒季、小白菜季均以化肥(NPK)处理(40d)最高,辣椒季为(156.80±23.38) mg/kg,小白菜季为(349.35±7.29) mg/kg;有效磷含量辣椒季以化肥处理(60d)最高,为(160.35±31.21) mg/kg,小白菜季以化肥+氧化镁(NPK+MgO)处理的最高,为(211.13±7.34) mg/kg;速效钾含量以化肥+酸化调理剂1号(NPK+SR1)处理的最高,辣椒季均值为(155.6±16.65)mg/kg,小白菜季均值为(278.91±3.5) mg/kg;不同施肥处理对土壤pH、交换性酸(EA)和土壤...

Through field experiment, the effects of several fertilizations and acid soil conditioners on the soil acidity, available nutrient status of the acid red soil developed from Quaternary red earth and on crop yields were investigated. The results showed that there was statistically significant difference in alkali-hydrolyzable N content among soils treated with different fertilizations. Treatments （40d） with chemical fertilizer （NPK） in pepper season and Chinese cabbage season both showed the highest alkali-hydrolyzable N content, which was （...
