| 摘 要： | 在北方地区耕层土壤,速效钾含量在85 PPM左右的岗地轻壤质褐土上,进行高产栽培,在施用较多的有机肥和氮、磷肥的基础上,施钾肥后小麦获得了显著的增产效果。增产幅度达6.3—13.3％。建议在此类土壤上进行高产栽培时,可结合钾肥的分期施用,对提高小麦产量有良好的效果。施钾量以亩施K_2O16斤为最理想。

| Abstract: | On the cultivated horizon in North China, when we make a high-yielding culture in the hillock light loam cinnamon soil,in which the content of quick-acting potash is about 85 ppm, after basal application of enough organic, azotic and phosphatic fertilizer,the wheat yield can be greatly increased by application of potassium ferttilzer.The range of the increase of wheat is from 6.3% to 13.3%. Therefore, we propose that we should apply potassium fertilizer by stages to get a high yield of wheat when the high-yielding culture is made in the soil of this kind. The best amount of application potassium fertilizer (K_2O) is 8 kg per mu. |
