Study on Applied Effect of Red-Yellow Soil Conditioner
摘要
Abstract
In order to explore the effect of improving soil structure and fertility of Red -Yellow Soil Conditioner ( RYSC) appli-cation in red soil upland and its yield -increasing effect under the condition of different application rates , we carried out peanut , sweet potato and tobacco field tests for the application rate of RYSC at three test points in the representative hilly red soil region . The results of 2-year location tests indicated that the application of RYSC in the red soil upland had favorable effect of improving soil structure and fertility , it could effectively adjust soil acidity , improve soil structure , and increase soil nutrient and organic mat-ter content.After the application of RYSC, the soil pH -value was increased by 0.15~0.19, the bulk density of soil was de-creased by 5~6 percent, and the soil organic matter content was enhanced by 2.2~2.8 g/kg.As for the application of RYSC in peanut, sweet potato and tobacco fields , its suitable application rate was 1500~2000, 2250~3000, 1500~1800 kg/hm2 respec-tively, and the yield was increased by 8%~11%, 9%~14%, 6%~9%respectively in comparison with the control ( without the application of RYSC ) .关键词
