文冠果在生产中的一个严重问题是开花多,座果少,故有“千花一果”之说。为提高文冠果的座果率,增加单位面积产量和进行有效的杂交育种,观察研究其花的生物学特性是十分必要的。但目前有关这方面的报道很少。我们于1978—1980年开展了此项试验。现将观察结果报告如下。一、观察地点及土壤气候条件观察地点是在内蒙古通辽县文冠果林场进行的。该场气候特点是:春季干旱,夏季酷热,冬季严寒。年平均气温5—6℃,1月份平均气温-13°至-18℃,7月份平均气温24℃,极端最低气温-34.7℃,极端最高气温39.5℃。年平均降雨量400毫米,蒸发量达1800毫米。
A serious problem in the production of Wen Guan Guo is that it has more flowering and less fruit, so it is said that “a flower is a fruit.” In order to improve the fruit set rate, increase yield per unit area and carry out effective cross breeding, it is necessary to observe and study the biological characteristics of the flower. However, there are few reports on this issue at present. We conducted this experiment in 1978-1980. The observations are reported below. First, the observation site and soil climate conditions observation site is in Tongliao County, Inner Mongolia fruit tree forest site. The climate is characterized by: spring drought, hot summer and winter cold. The annual average temperature of 5-6 ℃, January average temperature of -13 ° to -18 ℃, July average temperature of 24 ℃, the extreme minimum temperature of -34.7 ℃, the extreme maximum temperature of 39.5 ℃. The average annual rainfall of 400 mm, evaporation of 1,800 mm.
