摘要: |
选择尿素、钙镁磷肥、硫酸钾、硫酸铜、硫酸锌、硼酸为基本成分,以不同浓度按均匀设计法组成不同配方,对银杏嫁接苗定植后第2年的植株进行施肥试验。测量植株在不同时期的生长量及计算年总生长量;每隔1个月采叶样分析营养成分;初步确定银杏幼苗的施肥模式为:尿素30克/株~60克/株,钙镁磷肥450克/株~1200克/株,硫酸钾200克/株~320克/株,硫酸铜1.5克/株~4.5克/株,硫酸锌1.0克/株~4.5克/株,硼酸3.5克/株~4.0克/株;施肥时间在每年的6月份前比较合适。 |

Abstract: |
With the method of uniform design, six common fertilizers(Urea,Calcium magnesium phosphate,potassium sulphate,Copper sulphate,Zinc sulphate,Boric acid) were selected as basic components to compose different complex fertilizers with different dosage.With these complex fertilizers,a combination fertilization experiment was carried out on the grafting seedlings of Ginkgo in the following year after plantation.The growth of the plants was measured in different stage and the annual growth was calculated.Their leaves samples were collected every other month and the contents of nutriment were analyzed.Based on these results,the relationship between dressing factors and annual growth were analyzed.The preliminary fertilization model for Ginkgo young plants in southern China was determined.The dressing dosage:Urea 30~60 g/seedling,Calcium magncsium phosphate 450~1200 g/sccdling,Potassium sulphate 200~320 g/seedling,Copper sulphate 1.5~4.5 g/seedling,Zinc sulphate 1.0~4.5 g/seedling,Boric acid 3.5~4.0 g/seedling; and the suitable dressing time is prior to June every year. |
