【摘要】 在广东省两个试点进行田间小区试验,水稻施用味精废液有机无机BB肥1000 kg.hm-2,与习惯施肥相比增产320 kg.hm-2,达显著标准;产投比值为2.08,收益明显;土壤有机质、N、P2O5、K2O含量与种植前有不同程度的增加。施味精废液有机无机BB肥,不但能满足水稻对氮、磷、钾大量元素的需求,同时具有改土、培肥地力的作用。该肥作基肥一次施用,能有效节约劳动力投入。更多还原

【Abstract】 Rice experiments were conducted for studying organic-inorganic BB fertilizer made of monosodium glutamate waste water in Guangdong Province.The results showed that the rice yield increased by 320 kg·hm-2 at the rate of 1000 kg·hm-2 compared to the control,reaching the LSD0.05.The output-input ratio was 2.08 according to current prices of the fertilizers and rice.The effects of organic-inorganic BB fertilizer were obvious on increasing yield and income,improving soil and labor-force saving when it was used totally as basal dressing in one time.更多还原
