- Title:
- Vegetable Cultivation Mode and Fertilization of Greenhouse in Yan’an
- Keywords:
- Yan/an greenhouse; vegetable; cultivation mode; fertilization

- 摘要:
- 对延安日光温室蔬菜栽培模式与施肥状况进行调查，蔬菜栽培模式有两种即果菜-果菜和果菜-叶菜。有机肥最高施用量为165000 kg/hm2，平均为105983kg/hm2；氮肥的最高施用量为28800 kg/hm2，平均为6000 kg/hm2，磷肥的最高施用量为4950 kg/hm2，平均为3009 kg/hm2；钾肥的最高施用量为1162 kg/hm2，平均为331.82 kg/hm2 。施肥结构不合理，氮肥施用量大，磷肥偏少，钾肥严重亏缺，结合试验研究结果，提出适宜的蔬菜栽培模式、合理的施肥量及施肥结构。
- Abstract:
- After investigating and analysing greenhouse cultivation mode and fertilization of vegetable in Yan’an city,there are two vegetable cultivation modes,fruit and melon vegetable-fruit and melon vegetable,fruit and melon vegetable-green vegetable.The maximum amount of organic fertilizer used is 165 000 kg/hm2,the average amount is 105 983 kg/hm2,the highest amount of nitrogen fertilizer used is 28 800 kg/hm2,the average amount is 6 000 kg/hm2,the biggest use of phosphatic fertilizer is 4 950 kg/hm2,the average amount is 3 009 kg/hm2,the maximum amount of potassic fertilizer used is 1 162 kg/hm2,the average amount is 331.82 kg/hm2.The fertilization structure is irrational,large amount of nitrogen fertilizer and less phosphatic fertilizer were applied as well as the lack of potassic fertilizer.Finally,the favorable vegetable cultivation mode,rational fertilizer use and fertilization structure are raised.
