根据国内外的大量研究资料表明,西红柿、黄瓜要求大量的氮、磷、钾养分,日本的掘裕对谣红柿等五种果菜,氮、磷、钾吸收量的平均统计表明,每亩8000斤的产量需要氮21.6～32.8斤,磷7.0～10.4斤,钾34.6～47.6斤。市农科院78年对西红柿使用磷、钾后的产量和质量分析都表明,效果极为显著。目前生产上对氮肥的使用较多,所以我们重点分析磷、钾的在城区部分社队蔬菜产区的施用效果,下面将我们的试验结果整理如下:
According to a large number of domestic and foreign research data show that tomatoes, cucumbers require a large number of nitrogen, phosphorus and potassium nutrients, Japan’s digging on the ruddy tomatoes and other five kinds of fruit and vegetable, nitrogen, phosphorus and potassium absorption of the average statistics show that 8000 acres per mu Kg yield of nitrogen need 21.6 ~ 32.8 kg, phosphorus 7.0 ~ 10.4 kg, potassium 34.6 ~ 47.6 kg. City Academy of Agricultural Sciences 78 years of tomatoes using phosphorus and potassium yield and quality analysis have shown that the effect is extremely significant. At present, the production of nitrogen fertilizer use more, so we focus on analysis of phosphorus and potassium in the urban part of the commune team vegetable production application, the following test results are summarized as follows:
