最适宜君子兰发育生长的气温条件是15℃—25℃。当气温在25℃以上时,一般停止生长;30℃以上如湿度过大,则会出现徒长,叶片明显变长变窄,管理不当还会出现病害;气温低于10℃时,生长速度变慢,8℃以下停止生长。因此,必须根据气温的变化管理好君子兰。春、秋季节,气温适当,是君子兰生长的旺盛时期。最好在二月下旬和九月底前后(天津地区的气温)换一次新土,一年生小苗可不换。培养土可用腐叶±50％,发酵马粪30％,2—3毫米直径的粗砂或煤渣(轻质多孔的)20％配制;或用腐叶土40％,马粪20％,粗砂20％,骨粉20％配制。每隔10—15天施一次,用豆饼、淡水鱼下水、蹄壳等沤制的液肥。要坚持薄肥勤施的原则。液肥浓度,应根据原液
The most suitable temperature for the growth of Clivia is 15 ℃ -25 ℃. When the temperature is above 25 ℃, the general stop the growth; 30 ℃ above the humidity is too large, it will appear leggy, the leaves become significantly longer and narrower, mismanagement will occur disease; temperatures below 10 ℃, the growth rate slows , Below 8 ℃ to stop growing. Therefore, the climber must be managed according to the temperature change. Spring and autumn seasons, the temperature is appropriate, is the vigorous growth of Clivia. Best in late February and late September (the temperature in Tianjin) for a new soil, annual seedlings can not change. The cultivated soil can be prepared with rotten leaf ± 50%, fermented horse manure 30%, 2-3 mm diameter grit or cinder (light and porous) 20%; or 40% 20%, 20% bone meal preparation. Apply once every 10-15 days, with beancake, freshwater fish into the water, hoofs, etc. 沤 system of liquid fertilizer. To adhere to the principle of thin fertilizer Qin Shi. Liquid fertilizer concentration, should be based on stock solution
