一 前言 油瓜[Hodgsonia macrocarpa(Bl.)Cogn.]自1960年在我园引种栽培以来,在繁殖、栽培和生物学特性研究工作中,取得了一些进展。虽然要完全实现油瓜家化还不是短期的事,但已有的工作结果,已为我们展示了未来家化的途径和前景。 根据目前工作的情况,油瓜的人工栽培利用的主要习性和技术已经掌握。并已经在云南、广东等地开展推广试种工作。因此,尽早把有关生物学特性的研究成果推荐出来,对于当前的推广试种工作是有益处的。现在特把未发表过的有关生物学特性的资料整理出来,向有关单位与同志汇报和求教。 二 野生分布 油瓜分布于北纬24°以南直到赤道附近,在马来、印度及中印三半岛诸国和我国云南南部,广西大部分地区,广东湛江专区各县山区和肇庆专区西江沿岸各县山区都有野生资源。其分布特点如下: (1)周年有流水的山溪、沟谷两旁; (2)在阔叶林覆盖之下,常伴有各种热带亚热带地区特有的嗜湿性的耐阴植物; (3)着生的坡面不高,多不超过距谷底50米处,且以20米以下为最多;
A Preamble Since the introduction and cultivation of Hodgsonia macrocarpa (Bl.) Cogn. In our garden in 1960, some progress has been made in researches on breeding, cultivation and biological characteristics. Although it is not yet a short-term task to fully realize the melon establishment, the results of our work have shown us the ways and prospects for future development. According to the current work situation, the main habits and techniques of artificial cultivation and utilization of melon have been mastered. And has been in Yunnan, Guangdong and other places to promote trial planting work. Therefore, recommending the research results on biological characteristics as soon as possible is beneficial to the current popularization and cultivation work. Now we have put out unpublished data on biological characteristics and reported and solicited advice to relevant units and comrades. Two wild distribution of melon distributed in the latitude 24 degrees south until the equator near the Malay, India and China Peninsula Peninsula countries and our country southern Yunnan, Guangxi most of the area, Guangdong Zhanjiang area counties mountainous areas and Zhaoqing area along the Xijiang County mountainous areas have wild resources. Its distribution features are as follows: (1) annual mountain streams, valleys on both sides; (2) in the broad-leaved forest cover, often accompanied by a variety of tropical subtropical peculiar hygroscopic plants; (3) Raw slope is not high, not more than 50 meters away from the valley, and to 20 meters below the most;
