张家口地区杏扁面积大,但由于栽培管理技术落后,成龄树多为低产园,严重制约着杏业生产的发展。为了研究成龄杏树增产潜力和综合管理技术,确立丰产园的树体结构及其技术指标,为杏扁大面积丰产示范提供依据,本课题组在1989年对丰产园进行了调查,现将情况报告如下。
Zhangjiakou area apricot large area, but because of the cultivation and management of backward technology, mostly low-yield mature garden, severely restricted the development of apricot production. In order to study the yield potential of apricot and the integrated management techniques, the tree structure and its technical index of high yield garden were established, which provided the basis for the large-scale high yield demonstration of apricot. The group conducted a survey on high yield garden in 1989, The situation report is as follows.
