| 摘 要： | 通过观测不同施肥处理区寒害腰果植株重新开花坐果状况，分析施肥对寒害腰果植株恢复生长的影响，并分析腰果叶片养分含量与结果量之间的关系。结果表明：氮对寒害腰果植株重新开花的花枝数影响最大，钾次之，磷影响最小，随着氮施用量的增加，植株的花枝数逐渐增大；氮是影响寒害腰果植株结果量的主要因素，植株结果量随着氮施用量的增加而增加，磷、钾各处理间的结果量均未达到统计上显著差异；在施氮肥的基础上，配施磷钾肥，可以提高寒害腰果植株结果量，9个施肥处理中以N3P3K2处理的结果量最多。

| Abstract: | in this paper,we surveyed the reflorescence and fruit setting situation of cold injured cashew in different fertilization treatment areas,analyzed the effect of fertilization level on recovery growth of cold injured cashew,and analyzed the relationship between cashew leaf nutrient content and fruit quantity.The results indicated that,nitrogen fertilizer had the most influence on the number of flower branch of cold injured cashew,potassium fertilizer took the second place,and phosphorus fertilizer had the le... |
