摘要
为促进珍珠番石榴在贵州地区的推广种植,通过生物学调查及肥效试验研究了珍珠番石榴在贵州的表现及主要栽培技术。结果表明：珍珠番石榴在贵州种植适应性强、早结丰产,周年开花结果;从修剪处理到开花需要61-64 d,从开花到果实成熟,夏季果需要100 d左右,冬季果需要140 d左右;经回归分析表明,单株产量与干径呈显著相关关系,枝组产量与枝组粗度呈显著相关关系;两年生珍珠番石榴年施用尿素、过磷酸钙和氯化钾的最佳用量分别为0.8 kg/株0、.6 kg/株和0.8 kg/株。说明,珍珠番石榴适宜在贵州亚热带地区种植。
The growth performance of introduced pearl Psidium guajava and its main cultivation technique were studied by biological investigation and fertilizer efficiency tests to promote popularization of pearl Psidium guajava in Guizhou.The results show that the growth performance of pearl Psidium guajava has features of strong adaptability,early fruit-bearing,high yield,and flowering and fruit-bearing in the same year,61～64d from pruning to flowering,about 100d from flowering to fruit maturity in summer and about 140d from flowering to fruit maturity in winter.The regression analysis results showed that the yield per plant was significantly correlated with the trunk diameter and the branch yield was significantly correlated with the branch diameter,and the optimum application amount of urea,superphosphate and potassium chloride for single biennial pearl Psidium guajava was 0.8kg,0.6kg and 0.8kg respectively.The Psidium guajava can be planted in subtropical regions of Guizhou province.
