摘要
"吉夫纳"作为当前广西番荔枝产业发展的主要品种,其种植效益尤为突出.通过多年观察该品种的植物学特性、生长结果习性、果实经济性状和物候期等特性,发现其在广西种植区的综合表现优良,具体表现为:早结,定植2年即可投产;丰产,每667 m2平均产量可达1151.7 kg;优质,可溶性固形物含量为21.68％、维生素C含量为32.40 mg/100g、K含量为284.82 mg/100g、Ca含量为25.02 mg/100g;产期易调节,4月～10月修剪即可成花.并探索总结出该品种在高标准建园、强化水肥管理、科学产期调节、精细花果管理和综合防控病虫害等栽培领域上的技术要点,以期为"吉夫纳"在广西适栽区的推广应用提供理论参考.
Abstract
As a characteristic fruit of tropical and South subtropical regions"Givner",Annona has a unique flavor in its flesh,rich in nutrients such as vitamins and carbohydrates.It is loved by the majority of consumers and has great market potential.However,its industrial development is relatively late,the research foundation in various fields is weak,and the lack of standardized cultivation technology can not meet the situation of continuous development of the industry.In order to improve the healthy development of the Annona industry in Guangxi,this paper studied and observed the botanical characteristics,growth and bearing habits,fruit economic characteristics,and phenological period of"Givner"in the Guangxi cultivation area.It also summarized the technical fields of this variety,such as high standard garden construction,enhanced water and fertilizer management,scientific perinatology regulation,fine fruit and fruit management,and comprehensive prevention and control of pests and diseases.The aim is to improve the cultivation technology of"Givner"in the suitable planting area of Guangxi,and provide technical and theoretical references for the sustainable development of the industry.
