一、看花 生长势强的植株，伸长的雌花向下开放，花瓣大，色鲜黄。如果伸长的雌花短而细，横向开放，子房弯曲，花瓣色淡黄，表明生长势弱，应加强肥水管理。如雌花向上开放，则表明生长势更弱。如果各叶腋都出现雌花，甚至出现两个以上雌花，是乙烯处理浓度偏大造成的，应提高 First, see the plants growing strong perennial, elongation of the female flowers open down, petal, yellow color. If the elongation of the female flower short and thin, horizontal open, ovary bending, petal color yellow, indicating weak growth, fertilizer and water management should be strengthened. If the female flowers open upward, then the growth potential is weaker. If each leaf axils appear female flowers, or even more than two female flowers, is caused by the ethylene concentration is too large, should be increased
