During the severe winter season from December to February of next year, the potted Rhododendron was packed with non-toxic plastic bags, and sunned for 4 hours a day (light can be used instead of cloudy days). The temperature in the bags was 5 to 7 degrees higher than that in the indoor.In this way, as long as four hours of sunshine are guaranteed every day, the temperature at night is not less than 9 degrees Celsius, and the branches can be covered with plastic bags for about 50 days.But we must pay attention to the following points: we must choose early flowering varieties.Such as Paeonia suffruticosa, white peony, Wang Guan, Feng Ming brocade, Dan Ding, peony, spring friendship, hi Ying Chun and so on.The temperature of early flowering varieties is not the same.Store the plants at 10 degrees Ce呂修斯If you want to blossom during the Spring Festival, you need to put on plastic bags 40 days in advance to warm them up.Among them, Paeonia suffruticosa, white peony, Feng Ming brocade, etc., usually more than 30 days in advance.The water temperature should not be lower than the room temperature.It s應該注意的是,袋子里的溫度不應該太高。If it is too high, the mouth of the bag should be loosened and tightened until the heat is released.When you see that the Rhododendron in the plastic bag is budding, you can remove the plastic bag, stop heating, and keep the temperature above and below 10 degrees Celsius.The leaves were sprayed one or two times a day with the same water at room temperature, and the flowering period could be maintained for 30 days to 40 days.Thus, the Rhododendron after the above treatment can bloom in the Spring Festival, which is full of snow and cold.Paeonia suffruticosa is not very strict with peony cultivars.Generally, most of them are adaptable varieties, such as Hu Hong, Zhu Shalei, Zhao powder and so on.Choose three or four year old healthy plants.The potting time should be flexibly controlled according to the local temperature. When it is cold in the morning, the potting time should be properly postponed if it is warm.The key to Paeonia suffruticosa winter flower forcing is to master temperature.After the peony enters the room, it can be divided into two stages to master the change of temperature.The first stage is the heating stage.One week after entering the room, the temperature is controlled at 8-12 degrees Celsius, then the temperature is raised to 18-20 degrees Celsius for half a month, and then the temperature is raised to 20-24 degrees Celsius for a week.At this time, the flower has been exposed, and then into the second stage, namely cooling stage, the temperature will be reduced to 16-18 degrees Celsius, a week later, it can blossom, if the flowers blossom faster, the temperature can be reduced to 14-16 degrees Celsius, in order to prolong the flowering period and ensure Festival flowers.Paeonia su冬季必須保持環境濕度,室內空氣濕度應保持在80%以上,由于室內溫度高,耗水量大,需經常用水噴淋,常規做法是:小水,隔日一次。每天早晨和傍晚的射線水,發現溫度較高(超過24攝氏度),還噴水降溫。通過噴灑水分調節溫度和濕度,樹枝和樹葉保持新鮮,土壤保持干燥和濕潤。
