“冬芽定量”对“金魁”猕猴桃生产的影响

Quantity of Winter Buds and Productivity of Actinidia chinensis var. deliciosa ‘Jinkui’

冬芽管理是猕猴桃树体管理的重要环节之一。适宜的高质量冬芽保留,可较准确预测果实数量,提高果实大小一致性。本研究在江西省猕猴桃主栽区奉新县的赤岸镇山口果园,以10年生"金魁"猕猴桃为研究对象,研究冬芽保留数量对果实生产的影响。结果表明,在试验区立地条件和现有管理水平下,单位面积(18m2,下同)冬芽保留量约450个,有利于提高种植经济效益。

Number of winter buds is a determinant of kiwifruit yield. Maintaining an adequate number of high quality winter buds can predict fruit number and improve fruit size and uniformity. Effect of different quantity of winter buds on ＂Jinkui＂ kiwifruit yield was researched in orchards in China town, Fengxin county of Jiangxi province. The result showed that an optimal number of 450 winter buds oh 18 m^2 of land was judged the best in improving the economic returns to growers.
