解放后在党的领导重視下,我国园艺事業有很大的发展和提高,成都作到菊花常开。这里把我們成都地区作提前或延迟开花的栽培,点滴收获,提出来供大家参考。菊花是一种短日照植物。在发育期若光照長至14—15小时它不继续发育,不开花,只是生長。作“秋菊冬开”曾经这样对照观察。秋季八月中旬扦插繁殖,生根后上盆,摘心,那时每日的光照漸渐缩短,为了使菊花只生長,不繼續发育,不开花,我們每日用电光(日光灯40瓦)加長光照到16小时左右。同时使有几株在自然光照下生長。
After the liberation, under the leadership of the party, great progress has been made in the development of horticulture in our country. In Chengdu, chrysanthemum is often opened. Here we Chengdu region for early or late flowering cultivation, bit by bit harvest, put forward for your reference. Chrysanthemum is a short-day plant. If the growth period of light to 14-15 hours long it does not continue to develop, not flowering, but growth. As “Chrysanthemum winter open” had such a controlled observation. Autumn in mid-August cutting propagation, after the root on the pot, topping, then gradually reduce the daily light, in order to make the chrysanthemum grow only, do not continue to develop, not flowering, daily electricity (fluorescent 40 W) To 16 hours or so. While allowing several strains to grow in natural light.
