【摘要】 黄泥田具有耕层浅薄、耕性不良、土壤贫瘦、养分比例失调等低产因素。土壤具有前期供肥慢、肥劲小、水稻分蘖力低、源足库小的生产弱点。采用增施有机肥,结合合理深耕,增施钾肥,调节氮、磷、钾养分比例,合理施用微肥及其他综合农业措施,是综合改良利用黄泥田的有效途径。更多还原

【Abstract】 The low-yiedding factors of yellow paddy soil is shallow plough layer, bad plowing property, low nutrition and nutrive disturbance. The poor productivity of this soil is characterized to be nutrient slow-supply in rice early growing stage, lesser efficiency, low tillering capacity and smaller metabolic pool which could not congruent with rich metabolic source.As the results we studied in Fujian showed to combine the application of organic manure with other agronomic practice such as deep plonghing rationally, increasing potassium fertilizer and adjusting N.P.K. nutrient rate, reasonable application of microfertilizer, was the effective measure for the comprehensive improvement and utilization of yellow paddy soil.更多还原
