本试验于1992年在崖城（北纬18°27’）进行。采用6个在当地不开花和难开花的品种，主要结果如下：（1）所用品种（Co419，华南56－12、华南56－21，粤据59-95，粤糖57－423和Badila）全部抽穗开花；（2）降低夜温或（和）延长固定光照（12h25min）可提高孕穗率，抽穗率和提早粤糖57-423开花期；（3）9月6日以后的固定光照处理效果比9月6日以前的好；（4）崖城11月以后的光或室内夜温非常适合花芽分化的诱导。笔者认为，利用冬、春诱导来促进难开花和不开花品种开花是一种经济有效的办法。 This test was conducted in Yacheng (latitude 18 ° 27 ’) in 1992. The main results are as follows: (1) All the cultivars (Co419, South China 56-12, South China 56-21, Guangdong 59-95, Yantang 57-423 and Badila) (2) Reducing night temperature or (and) prolonging fixed illumination (12h25min) could increase the booting rate, heading rate and early flowering period of 57-423. (3) The effect of fixed illumination after September 6 September 6 before the good; (4) Yacheng after November light or indoor night temperature is very suitable for the induction of flower bud differentiation. The author believes that the use of winter and spring induced to promote flowering and flowering is not a flowering species is a cost-effective approach.
