针对衢县椪柑生产中果形偏小、品质欠佳和商品率低等问题 ,经大面积推广疏株、疏大枝、疏果、增施有机肥改良土壤 (三疏一改 )和果品贮藏保鲜技术后表明 :实施以“三疏一改”为核心的低改技术 ,基地平均产量超过 45t·hm-2 ,特级和一级果率由实施前的 30 %提高到 78% ,增加 1 60 % ,二级和三级果明显减小 ;年增收 0 2 6万～ 1 88万元·hm-2 ,投产比达 1∶4～ 6。推广万利得贮藏保鲜技术 ,果品保鲜时间达 3～ 4个月 ,好果率提高 3 4% ,衢县柑有 95 %果品实施贮藏保鲜 ,减少了损耗。推广“三疏一改”和保鲜技术 ,经济效益十分显著。表 5参 5
In order to solve the problems of small fruit shape, poor quality and low commodity rate in the production of citrus fruit in Quxian County, the improvement of soil (three changes) and fruit preservation and storage After the technology shows that: the implementation of “three sparse changes” as the core of the low change technology, the base of the average output over 45t · hm-2, special and primary fruit rate from pre-implementation 30% to 78%, an increase of 160% , Secondary and tertiary fruit significantly reduced; annual income of 0.226 million ~ 18.8 million yuan · hm-2, put into production ratio of 1: 4 ~ 6. The promotion of Wanli storage and preservation technology, fruit preservation time of 3 to 4 months, a good fruit rate increased 34%, Quxian Kombu 95% of the fruit storage and preservation, reducing the loss. Promote the “three sparse changes” and preservation technology, economic efficiency is very significant. Table 5 reference 5
