　　 《砂糖橘優質豐産栽培彩色圖說》傾心打造。砂糖橘優質豐産的保證！

內容簡介

　　 《砂糖橘優質豐産栽培彩色圖說》作者潘文力副教授是仲愷農業技術學院著句的柑橘專傢，廣東省砂糖橘協會顧問，農業部農業行業標準NY/T869—2004“砂糖橘”主要製訂者，長年從事砂糖橘生産技術推廣，深受牛産者的信賴和喜歡。黃義東碩十，長期從事植保試驗示範推廣工作，熟悉砂糖橘生産，對砂糖橘病蟲害防治技術有實操經驗。
　　 該書凝聚瞭作者幾十年的牛産實踐經驗，以簡潔易懂的義字、豐富的原色圖片全麵介紹瞭砂糖橘優質豐産栽培技術，內容包括砂糖橘生産概述、主要品種品係、生長發育特性、苗木培育、果同建立、幼年樹管理、結果樹管理、主要病蟲害防治、果實采後商品化處理以及砂糖橘無公害食品生産等技術要求。書中重點突齣瞭各項關鍵技術，如控梢促花、保花保果、應節“葉橘”樹上保鮮等技術。
　　 同時在書末收錄瞭砂糖橘幼年樹、結果樹周年管理工作曆以及農藥稀釋用水量查對錶和農業部農業行業標準NY/T869—2004砂糖橘，方便讀者查閱應用，具有技術先進、措施得體、文字通俗、可操作性強等特點，適閤廣大果農、農業技術人員和相關農業院校的師生閱讀參考。

精彩書摘

（二）栽培區域
砂糖橘生産分布地域較窄，特彆是能生産春節上市的“葉橘”地域更窄，受製於過鼕時的氣溫，要求氣溫在0℃以上，否則會受霜凍。因樹上留果時果實已充分成熟，果皮開始衰老，氣溫0℃時稍遇風霜。即會齣現果皮鬆軟果而發生霜凍。若加上冷雨，則果皮發泡鬆軟．更加速冷害的發生。過鼕時高溫多雨，則會使果實汁胞粒化。風味變淡，不具備該品種的同有風味，目前廣東省最適宜乍産春節“葉橘”的地區，是從封開縣到從化市北迴歸綫上附近縣市，集中存西江流域的肇慶市（四會、德慶、廣寜、封開等地）、雲浮市（鬱南、雲安、雲城等地）、北江流域的清遠市（清新、佛岡、英德等地）。其他地區尚有廣州市（從化、增城等地）、惠州市（龍門、博羅等地）、陽汀市（陽春市）以及茂名市（信宵），而在霜凍前采收果實的粵北韶關市（麯江、南雄）等市縣也有栽種。廣東栽種麵積約200萬畝（畝為已廢除單位，l畝=l/15公頃＝667米。）。外省區以廣西栽種最早。麵積最大，一年內將會突破100萬畝，此外江兩、湖南、四川、重慶、浙江、湖北等省市均有引種。圍外亦有砂糖橘銷售，如加拿大溫哥華市9月上旬已在超市Ⅲ售。但該品種並不是廣東省的砂糖橘，可見本種影響力之大。
（三）經濟效益
四會市一直保持砂糖橘單株産量500於剋的曆史記錄。據2004年四會市砂糖橘“品味、株産、畝産”之最驗收評選的結果，單株估産量最高是16年生樹，為356.4韆剋，每畝種植73株，估産最高是15年生樹．約8906韆剋。2006年清新飛來峽鎮亦有25年生樹株估産250韆剋的“橘王”。一般植後3年試産。
