在对豫南漂白黄褐土特性研究的基础上 ,对其开展了深耕和增施有机肥的改良利用试验。结果表明 ,在常规化肥用量的基础上适当增加耕层深度和有机肥的用量 ,可以改良土壤 ,提高小麦产量。适当补充锌肥也有一定的增产效应 Based on the research on the characteristics of bleached yellow cinnamon in the south of Henan, this paper carried out experiments on the improvement and utilization of deep plowing and increasing organic fertilizer. The results showed that increasing the depth of plow layer and the amount of organic fertilizer on the basis of conventional fertilizer could improve the soil and increase the yield of wheat.
