中文摘要: |
通过分析1994~2000年陕西省关中灌区与渭北旱原农户信息监测资料,研究了两个苹果主产区的施肥状况,根据施肥量优化结果对施肥状况进行了评价,同时对苹果施肥中存在的主要问题进行了讨论。结论为:(1)农户间化肥投入不平衡现象严重,生产中需增加钾肥比例;(2)有机肥施用量下降;(3)施肥技术有待改善。 |
英文摘要: |
The situation of fertilization for apple orchards was analyzed by using the investigation data of Central Shaanxi irrigation region and Weibei rain-fed region in Shaanxi province from 1994 to 2000 and evaluated by using the optimal fertilizing schemes. The main problems of fertilization in orchards were discussed. The results are as follows: (1) the input of chemical fertilizer is unbalanced seriously among different farms, and the ratio of potassium fertilizer applied to apple need to be increased; (2)the rate of organic manure is decreasing; (3) the technology of fertilization need to be improved. |
