丘陵旱地柿树密植早果丰产栽培技术研究

The Cultivation Techniques of Closely Planted Persimmon (Diospyros kaki L. f. )for Early Fruiting and High Yield on Arid Hilly Area

对丘陵旱地密植柿树（DiospyraskakiL.f.）的早果丰产栽培技术进行了研究。结果表明：柿树成品苗以春季葫芽期定植成活率最高，大面积栽植成活率达96．8％；栽植密度以株行距2m×4m或3m×4m较为适宜；以定干高度60～80cm、自由纺锤形整形较好；采用幼树期（定植后3a内）以中短截为主、4a生以后以甩放为主的修剪措施，配合树下管理、保花保果、病虫害防治等技术，达到了3a开花、6a最高产24t·hm-2、7a生最高产36t·hm-2的效果。

The cultivation techniques of closely planted persimmon (Diospyras kaki L. f. )on arid hilly area were conducted on the purpose of early fruiting and high yield. The main results were as follows:96. 8% of survival rate of planting could be reached when the edings were planted on the stage of sprout in spring; The young persirnrnon tree could flower in its third year, the highest yield could be 24t·hm-2 in its 6th year and the highest yield could be 36 t·hm-2 in its 7th year on the conditions of 2 m ×4 m or 3 m ×4 m planting density, medified spindle of tree shape with 40-60 cm trunk height,proper pruning of the young trees, together with proper soil management, flowers and young fruit drop protection and pest control .
