- 摘要:
- 以叶用紫苏为试材，采用田间试验方法,在塑料大棚条件下,667 m2分别施纯氮0、2.5、7.5、12.5、17.5 kg (分别用CK、N1、N2、N3和N4表示),研究了不同施氮肥量对叶用紫苏产量的影响，以期为叶用紫苏氮肥施用提供参考依据。结果表明：增施氮肥对单株商品叶片数和叶产量的提高具有显著作用，然而随着氮肥量的增加，叶片数没有显著增加，其中“南韩苏子”与“延边一号”在N3处理下达到最大值，“吉林3号”在N4处理下达到最大值。从试验结果可知,以叶片数高产的最佳施氮肥量为667 m2 施氮7.5 kg；以叶片质量高产的最佳施肥量为667 m2施氮7.5~12.5 kg。因此对于东北地区的叶用紫苏产量的最佳施氮肥量为667 m2施氮12.5 kg。
- Abstract:
- Perilla frutescens for leaf use was used as test material,the effects of different nitrogen level 0,2.5,7.5,12.5,17.5 kg per 667 m2(CK,N1,N2,N3 and N4,respectively) on yield of Perilla frutescens for leaf use were calculated according to the field test method under the condition of plastic greenhouse in order to provide reference for the scientific management of nitrogen fertilizer for Perilla frutescens for leaf use of basil.The results showed that the application of nitrogen fertilizer had significant effect on the increase of leaf number and leaf yield.However,with the increase of nitrogen fertilizer,the difference of N4 treatment was much less than that of N3 treatment.‘Suzi of Nanhan’and ‘Yanbian 1’ reached the maximum under N3 treatment,‘Jilin 3’ reached the maximum under N4 treatment.From the results of this experiment,the optimum nitrogen application rate was 7.5 kg per 667 m2 with high leaf yield.The optimum amount of fertilizer was 7.5-12.5 kg per 667 m2.Therefore,the optimum nitrogen fertilizer for the yield of Perilla frutescens for leaf use of basil in northeastern region was 12.5 kg per 667 m2.
