Golden safflower likes warm, humid and semi-shady environment, temperature adaptation range is large, can grow normally in 18~40℃. But not cold, room temperature can not be lower than 15℃.

3. Cultivation techniques of golden safflower

Red flower potted soil, available peat soil or rotting soil plus 1/4 of the river sand or pearlite and a small amount of farm manure, pH 6 to 6.5, with a diameter of 10 cm to 15 cm round pot planting. The temperature adaptation range of this plant is large, and it can grow normally within 18~40℃, so it can be cultivated in a wide range, but it is not cold-resistant. It must ensure that the room temperature is not lower than 15℃, otherwise the plant will dormancy, the leaves will turn yellow, fall off, and stop growing. Avoid rapid temperature changes. The whole growing season should ensure that the basin soil is moist but not ponding, otherwise it will rot roots, and prevent ponding in the basin after rain. Avoid drought, pot topsoil about 1 cm dry can be watered, each time to irrigate thoroughly. Due to hairy foliage, watering water can not be sprinkled on the foliage, otherwise it will cause leaf decay. Dormancy begins in late autumn and early winter, so water less.

In spring, summer and autumn when potted plants grow vigorously, 20% cake fertilizer water is applied once every 2 weeks to 3 weeks, and 1% potassium dihydrogen phosphate is applied once a week from budding to flowering. Fertilization should be stopped in winter. The air humidity is maintained at 70%~90%, and the shade is 50%~80%. Too strong light will burn the leaves, while too weak light will make the plants grow excessively, affecting flowering. Warm and humid environment is very important for the growth of golden safflower, golden safflower in 15℃ to 35℃ temperature growth exuberant, flowering constantly.

Also belong to the same genus plants and large-leaf golden safflower. The pot soil is prepared from peat, moldy leaf soil and a quarter of river sand or pearlite and farm manure. The pH value is 6 to 6.5. It is planted in a round pot with a diameter of 10 cm to 15 cm. It prefers semi-shade environment, greenhouse cultivation needs about 50% shade in spring and summer, full sunlight in winter, suitable temperature for growth is 20℃ to 30℃, winter temperature is 13℃ to 16℃. Vigorous growth season hi sufficient water, to keep the pot soil moist, pot topsoil about 1 cm dry can be watered, each time to irrigate thoroughly. Basin soil permeability must be good, can not accumulate water, otherwise it will rot roots, after the rain to prevent basin water. Due to hairy foliage, watering water can not be sprinkled on the foliage, otherwise it will cause leaf decay. Dormancy begins in late autumn and early winter, so water less. When potted plants were growing vigorously, 20% cake fertilizer water was applied once every 2 weeks to 3 weeks, and 1% potassium dihydrogen phosphate was applied once a week from budding to flowering.
