- 摘要:
- 以龙泉务‘香白杏’树为试材,调查分析了北京市门头沟区龙泉镇龙泉务村现有杏园‘香白杏’开花坐果、杏园土壤营养、树体矿质营养、花期天气条件、栽培管理措施等现状;研究了喷布硼尿素液和0.05%硫酸锰溶液对‘香白杏’坐果率的影响,旨在探讨龙泉务‘香白杏’坐果率低的影响因素及解决措施,为‘香白杏’生产中制订丰产稳产栽培管理措施提供理论依据。结果表明:龙泉务‘香白杏’不完全花比率高;授粉不亲和;杏园土壤、树体营养不平衡,土壤有机质和氮缺乏,树体微量元素Mn、B缺乏;花期多大风、低温、干旱天气;果园粗放管理等均是造成龙泉务‘香白杏’坐果率低的影响因素。喷布硼尿素溶液、硫酸锰溶液和清水均能显著提高龙泉务‘香白杏’坐果率。
- Abstract:
- Taking apricot ‘Longquanwu Xiangbai’ as material,the factors influencing the percentage of fertile fruit,garden soil nutrient conditions,mineral nutrition of trees,weather conditions in flowering period,cultivation and management measures were investigated.Fruit setting rate after spraying different liquid were studied,to discuss the factors that influncing fruit setting rate and solving measures,in order to provide a theotetical basis for high yield production cultivation management.The results showed that,the factors influencing the lower percentage of fertile fruit of apricot ‘Longquanwu Xiangbai’ mainly include the higher percentage of incomplete flower;pollination incompatibility;organic matter and nitrogen deficiency in soil;manganese and borax deficiency in tree;gale,low temperature and dry weather at anthessis;extensive management in orchard.Spraying carbamide and borax solution,manganese sulfate solution or water significantly increased the percentage of fertile fruit of apricot ‘Longquanwu Xiangbai’.
