The suitable temperature for the growth of bracts is 15-25 ℃, and the safe overwintering temperature needs to be kept above 10 ℃, otherwise the plant will stop growing.
Goldbracts like a warm and humid environment with sufficient light, but pay attention to the appropriate light, avoid direct sunlight in summer, do a good job in shade, the best place to maintain in the semi shade, and pay attention to ventilation. Maintaining sufficient light in spring, autumn and winter is conducive to the healthy growth of plants and the reduction of disease. If the plant is placed in a shade environment for a long time, it will grow in vain, and the flowering period will be delayed, and the flowering will be less.
In the growing period of the flower, the pot soil should be kept moist, and the air humidity of the surrounding environment should be kept high, but it is not allowed to accumulate water, otherwise it is easy to rot. Generally, water once a day in spring and autumn. The air humidity around the flowerpot should be increased frequently in summer or in dry period. In summer, water should be poured 2-3 times a day, and spray water to the leaves at the same time. In winter, water should be controlled to keep the basin soil slightly wet. However, if the temperature is above 25 ℃ in the daytime and about 15 ℃ in the evening, the plants can still bloom, and the normal water and fertilizer management can be carried out at this time
The cultivation soil of the flower should be fertile, loose, well drained and permeable acid soil, and should not be sticky. For the allocation of basin soil, rotten leaf soil, garden soil, river sand and rotten organic fertilizer can be mixed evenly according to the proportion of 5:3:1:1.
Jinbao flower likes fertilizer. During the growing period, it applies the thin liquid fertilizer once every 1 or 2 weeks to promote the vigorous growth and flowering of the plant. During flowering period, it is necessary to apply two times of P and K fertilizer to ensure the nutrition supply of pregnant buds.
The diseases and insect pests of golden bracts mainly include red spider, aphid, scale insect, etc. the mixture of 1000 times lesbon and 800 times methylthiophane must be sprayed on the leaves once a month for control.
The common diseases of the flower are powdery mildew, coal pollution and so on. When the plant is infected, the former can use 70% sprays of wettable granules 800 to -000 times or 25% times of powder wetting particles 800~1000 times to spray the liquid to prevent and cure the disease. The latter generally uses 40% Omethoate 800 times liquid or 500~800 times of the spray of zein.
