朱砂李是我省优良地方品种之一。主要分布在海城、鞍山一带,已有二百多年的栽培历史。近年来已逐渐引往外省、市试栽。该品种抗寒力强,果实大、色泽鲜艳,甜酸可口、风味浓郁,品质极佳。但落花落果严重,往往是花开满树,结果却很少(一般盛果期树平均株产不到10斤)。产量低,成为推广该优良品种的一大障碍。为探讨朱砂李落花落果严重的原因,解决其在生产上存在的问题,我们于1983年进行了有关朱砂李座果问题的试验研究。一、试材和方法本试验在鞍山市汤岗子畜牧场李子园进 Cinnabar is one of the finest local varieties in our province. Mainly distributed in Haicheng, Anshan area, about 200 years of cultivation history. In recent years has gradually attracted to other provinces and cities planted.

In order to explore the reasons for the serious drop of vermilion flower and solve the problem of its production, we conducted a pilot study on the problem of vermilion fruit in 1983. First, the test materials and methods The test in Anshan City Tanggang livestock ranch plum Park into
