①水分控制用盆宜小不宜大。早春、秋冬低温季节尤应少浇水,避免茎叶腐烂,促使植株健壮。健壮植株所开的花必然花期长。但夏季高温、干燥,应多浇水、喷水,不使花柄失水下垂,缩短花期。②多施钾肥钾是植物代谢中多种酶的活化剂,能延长花期。如经常往盆中施少量草木灰,能为植株提供一定量的钾元素,同时还能起到灭菌作用。③光照和温度非洲紫罗兰是需较多低光照的中性植物。夜间温度24℃左右,白天17℃左右才能生
① water control basin should not be large. Early spring, especially in autumn and winter cold season should be less watering, to avoid stems and leaves decay, prompting plants robust. The flower that the robust plant has opened must have a long flowering period. However, the summer heat, dry, should be more watering, water spray, do not make flower stems sag, shorten the flowering. ② more potassium fertilizer Potassium is a variety of plant enzyme activator of metabolism, to extend the flowering period. As often to the pot a small amount of plant ash, can provide plants with a certain amount of potassium, but also play a role in sterilization. ③ light and temperature Africa violets is the need for more low light neutral plants. Night temperature of about 24 ℃, about 17 ℃ during the day to students
