摘要
调查分析了绵阳市郊区 (石马、龙门、塘汛 )蕃茄、黄瓜、菜豆 3种蔬菜的平衡施肥状况。结果发现其施肥养分比 (N∶P2 O5∶K2 O)分别为 1∶0 .6 2∶0 .6 0、1∶0 .53∶0 .57、1∶0 .52∶0 .6 0 ,与其吸肥特性相比 ,施氮相对较多 ,施钾明显偏低 ,氮钾比失调。因此 ,推荐施肥方案要求控制氮肥 ,保证磷肥 ,增加钾肥用量 ,使施肥的N∶P2 O5∶K2 O分别应达到 1∶0 .6 2∶1.10 (蕃茄 ) ,1∶0 .55∶1.2 0 (黄瓜 ) ,1∶0 .50∶1.15(菜豆 )。
The present situation of fertilization for 3 kinds of vegetables, i.e. tomato, cucumber and kidney bean, in outskirts of Mianyang city (including towns of Shima, Longmen, Tangxun) was investigated. The fertilization ratios of N∶P 2O 5∶K 2O were 1∶0.62∶0.60 in tomato, 1∶0.53∶0.57 in cucumber, and 1∶0.52∶0.6 in kidney bean respectively. Compared with the nutrient absorption ratios, nitrogen was more, potassium obviously less, and the ratios of nitrogen and potassium were of imbalance. So, the request of recommendation fertilization plan controlled the amount of nitrogen fertilizer, assured the provision of phosphorus, increased the application of potassium, and made application ratios of N∶P 2O 5∶K 2O reach to 1∶0.62∶1.10 in tomato, 1∶0.55∶1.20 in cucumber and 1∶0.5∶1.15 in kidney bean respectively.
