Development of Micronutrient Fertilizer II. Effect of Micronutrient Fertilizer on Chinese Cabbage

종합미량원소비료(綜合微量元素肥料)의 개발(開發)에 관(關)한 연구(硏究) II. 비효시험

A pot experiment was carried out to evaluate the effect of a newly developed micronutrient fertilizer made of local mineral ores by the molten process. Chinese cabbage was used as the test crop and cultured on sandy loam soil to be highly responsive to applied micronutrients. The following results have been obtained from the experiment. 1. By the application of micronutrient fertilizer, the yield of chinese cabbage was increased about 30 to 40 percent compared to control. 2. Boron uptake by plants was remarkably increased in micronutrient fertilizer treatment, but the uptake of the others was not significantly. 3. After cultivation, boron content was high in micronutrient fertilizer treatment, however, the others was same as control.

국내산(國內産) 광물(鑛物)을 주(主) 원료(原料)로 이용(利用) 용융방법(熔融方法)으로 종합미량원소비료(綜合微量元素肥料)를 제조(製造)하여 배추를 공시(供試) 비효시험을 실시(實施)하여 다음과 같은 결과(結果)를 얻었다. 1. 종합미량원소비료(綜合微量元素肥料) 시용(施用)으로 대조구(對照區)에 비(比)하여 30-40%의 증수효과가 있었다. 2. 식물분 미량원소흡수량(微量元素吸收量)은 B의 경우(境遇) 현저(顯著)하게 증가(增加)하였으나 Fe, Mn, Mo, Zn은 증가(增加)하지 않았다. 3. 시험후(試驗後) 토양중(土壤中) 미량원소(微量元素) 함량(含量)은 B의 경우(境遇) 증가(增加)되었으나 기타(其他) 미량원소(微量元素)는 차이(差異)가 없었다.
