First of all, according to the overwintering requirements of various indoor foliage plants, strengthen the management of pipes, especially for the varieties with poor cold resistance, if necessary, focus on the places with increased temperature and heat preservation, so as to avoid the invasion of cold wind and avoid the adverse low temperature period.
Secondly, according to the change of temperature at the end of autumn, let it have a transitional adaptation process to low temperature, that is, when the temperature gradually decreases at the turn of autumn and winter, let the indoor foliage plants gradually exercise through a little low temperature, so as to significantly improve their adaptability to cold, make their own cold resistance potential fully play, and thus improve their resistance to low temperature. At the same time, in the winter low temperature period, it is necessary to avoid the uneven change of football instant score temperature, so as to help the plants survive the winter safely. Because the sudden increase of temperature will make the plants which are in relative dormancy state grow new shoots and leaves. At this time, if the temperature suddenly decreases, they are very vulnerable to freezing. In the same way, when early spring comes, the temperature changes indefinitely, so it is necessary to pay attention to the indoor foliage plants to prevent cold and antifreeze, so normal fertilizer and water management can only be carried out when the temperature is relatively stable.
Thirdly, the management of fertilizer and water should be done well in cultivation, so as to prevent cold and frost. In the winter low temperature period, the water content should be strictly controlled to make the excessive exercise in a relatively dry state. For most varieties, watering once in 5-7 days or longer is generally necessary to maintain the normal life activities of the tree, which is conducive to the increase of cell fluid concentration in the plant body and the improvement of its cold resistance; in winter, fertilization is generally not applied or less applied to control its growth and avoid freezing; in addition, about one month before the arrival of winter low temperature, in addition to the normal fertilization management, it is necessary to Increase the application of P and K fertilizer, such as spraying 0.3% - 0.5% potassium dihydrogen phosphate 2-3 times every other week to make the plant grow healthily, so as to improve the plant's winter hardiness.
