Gladiolus grows bulbs from spring to flowering and takes about 2 to 3 months. If it is planted in stages, it can be used for flowering all year round. The potted culture soil is applied to the base fertilizer, and the large flower pot can be planted 3 to 5 heads. The planting depth is 2 to 3 times the height of the bulb. After planting, pour the water for 1 to 2 times, then loosen the seedlings to prevent the water from ruining. Enter the growing season, especially when the flowers are in the order, the water and fertilizer should be sufficient. Gladiolus should be at a temperature of 20 to 25 ° C, and the growth at high temperature is poor. When the flower inflorescence is first opened, it can be cut in all order to make cut flowers. When cutting flowers, the original plant must have 3 to 4 leaves to produce nutrients for the development of the lower bulbs. One month after flowering, the apex of the leaves turns yellow, the bulbs can be dug out, the upper leaves are cut, dried, the old balls are removed, and stored in a ventilated dark room. The room temperature should be above O °C in winter.

Sun-Shading Net is a series of colored shade nets with special optical properties which improve the utilization of solar radiation by agricultural crops. This technology promotes differential stimulation of desirable physiological responses, which determine the commercial value of each crop. This is an economical and environmentally friendly alternative to current labor-consuming methods (such as pruning and thinning) and intensive use of growth regulators and other chemicals. ChromatiNet enables growers to control vegetative growth characteristics, such as leaf size, branch length and plant height in plants, as well as the rate of maturation and flowering. This enables adaptation to market preferences, with clear economic advantages.
Greenhouse Sun-Shading System can reduce solar load, and cool down the inside temperature and create a comfortable environment for the plants.
