摘要
1991~1994年,以五三农场果园为基点,采用普查,结合田间小区设计试验和室内样品分析,研究查明砂梨小果成因。通过疏花蔬果控制负载量;整形修剪改善光照;施用钾肥促使物质运转与积累;人工授粉提高果实种子数量与质量,促使梨树稳产、果大的技术效应明显。
During the period of 1991~1994, field investigations and experiments, integrated with labortory analyses were carried out on the fruit trees of Wushan farms orchard. The causes of fruit let formation in Sand Pear (Pyrus pyrifolia Nakai) were determinded, and the following methods produced significant effects in stablizing the yield and enlarging fruit size: controlling the crop load by thinning flower and thinning fruit;improving light intensity by training and pruning;stimulating the transportation, transformation and accumulation of substances in the body of the trees by applying potassium;--increasing the quantity and quality of seeds by artificial pollination.
