High Yield and Early Bearing Techniques for Tangerina —— Xingyi Dahongpao

为大面积发展兴义大红袍这一优良地方品种，通过对砧木、密度及系列栽培技术的试验示范研究，得出兴义大红袍早结丰产的技术关键是：以枳砧壮苗计划密植（密度为１１０～２００株／６６７ｍ２）；幼龄期薄肥勤施，盛果期增施钾肥；整形修剪以保春梢、控夏梢、促秋梢为主，注意适时间伐，把７０％～７５％的树冠覆盖率作为最佳调控指标；抓住病虫害的最佳防治期，进行联片综合防治。

? To expand cultivation areas of good tangerina variety —Xingyi Dahongpao,a series of studies on stock,planting density and culture techniques were conducted. The key techniques were summerized:using robast citrus trifolita as stock, planting in proper highdensity (110～220 plants/667m2);less amount but regularity applying fertilizers in the sapling stage, adding potash in the full fruit period,protecting spring shoot, controlling summer shoot, promoting autumn shoot by training and pruning, and reasonable intermediate cutting at proper time, taking canopy coverage from 70 to 75 percent as the best reference rate, seizing the best protection stage of diseases and pests to undertake the combined protection
