北方日光温室枇杷关键栽培技术

Cultivation Technology of Loquat in Greenhouse in Northern Area

为丰富北方都市农业温室栽培品种,将南方露地枇杷经温室护根育苗定植到日光温室中。通过整形修剪培育矮化树冠,采用控水肥促早花,夏季使用遮阳网、微喷等手段降温,实现了早于南方2~3个月上市。在温室栽培＂早钟6号＂枇杷,遵从其常绿果树周年生长特性,结合北方日光温室冬春季低温高湿生产实际生产条件,发挥日光温室夏季遮阳覆盖降温和冬季保温的功能,总结出北方温室枇杷水肥管理综合栽培技术措施。

To enrich the varieties cultivated in Northern greenhouse,the cultivation technologies of loquat were studied.Seedlings were obtained by root-protected method,and then were transplanted in the greenhouse.Branches were pruned to get the dwarf foliages.Fertilizer and water controlling brought the flowering time forward.Sun-shadding nets and spray irrigation were used in hot conditions.By using of the aboved technologies,fruits were harvested two months ahead of time compared with the south.We also found that the vareity ＂ZaoZhong No.6＂ was a suitable variety growing in the northern greenhouse.The technologis of the cultivation of loquat were summarized.
