| 摘 要： | 以2年生黑果枸杞苗为试验材料，设计氮、磷、钾3因素4水平施肥试验（“3414”试验），探索不同施肥方案对黑果枸杞生长的影响及氮磷钾合理施肥配比，为黑果枸杞生产过程中的配方施肥提供参考依据。试验根据黑果枸杞栽培群体各性状的变异系数，确定施肥效果中各性状所占比重；根据确定的比重，计算施肥后某一施肥方案对植株整体生长的影响效果；进而确定施肥的最佳方案。试验筛选出大田黑果枸杞开花前营养施肥的最佳配比为尿素18 g/株、过磷酸钙56 g/株、硫酸钾33 g/株，3种肥料中尿素对黑果枸杞植株营养生长效果明显，过磷酸钙、硫酸钾施肥后短期效果不明显。本研究为施肥效果评价提供了一种思路，并初步筛选出一种黑果枸杞生长期施肥的肥料配比和用量。

Fertilization Effect on Lycium ruthenicum in Growing Period |
| |
| Abstract: | Taking 2 years old Lycium ruthenicum seedings as experimental materials , the author designed a ‘3414’ test, in which N ,K , P straight fertilizers were used as 3 factors and 4 different concentration of them as 4 levels , to study the effects of different fertilization schedules and the rational fertilizers combination. The test was aimed at providing a reference for formula fertilization of Lycium ruthenicum in cultivation. According to the variation coefficient of the observed characters in cultivated group of Lycium ruthenicum, the study determined the weight of the growth characters in fertilization effect. And then, each of the fertilization schedule’s influence was figured out on plant’s entire growth. At last, the best fertilizer scheme was determined. The optimum fertilizer matching pre-bloom was figured out: 18g urea per plant; 56 g superphosphate per plant; 33g potassium sulphate per plant. In addition, the urea had an obvious effect on plants’ vegetative growth, while other two kinds of fertilizer had no obvious effect in short term. The study provide a new method to evaluate fertilization effect on Lycium ruthenicum and screen out a rational fertilizer matching and dosage. |
