Irrigation facilities Water is useful for chrysanthemum plant metabolic processes. In the body of plants, water acts not only as guardians of the temperature stability of plants to chemical processes in the body's metabolism of plants can run, but the water also serves as one of the main elements of the process of photosynthesis and the processes of synthesis of other important compounds. The water also serves as a means of transport of compounds from one plant part to another part of the plant.
In chrysanthemum crop water can be supplied in several ways, namely spray manually,flooding the system, using drip irrigation (drip system) and bulk irrigation (sprinkler irrigation). The combination of the two ways the latter is highly recommended in chrysanthemum cultivation. Both ways allow fertilizer can also be given together with the provision of water at the plant to spread evenly. When plants are young, giving water can be done through the sprinkler. This method has the advantages of water can be dispersed evenly and received plants and plants in growing medium can be saturated with the perfect bed to a young plant root growth not inhibited. However, this method resulted in high moisture at planting environment as well as leaves and plant bodies wetted by water, up to potentially cause disease attacks mainly white rust caused by Puccinia horiana. Therefore, provision of water through the sprinkler system is recommended in the morning until the body and the wetted leaves of plants can dry before noon.
Houses protected Protected home for the cultivation of chrysanthemums aims to protect plants from extreme weather conditions and environments that can negatively impact plant growth, such as light intensity is too high and the wind and rain water directly as well as crop pests, in order to obtain the optimal environmental conditions . Protected home made lengthwise adjusted to the size of land, with the width a multiple of 6.4 m. Framework of protected home can be a timber, bamboo, iron, aluminum, or concrete. Altitude ranges protected house 3-4 feet above ground level. The material covers a house roof can be protected using glass, plastic UV, PVC corrugated plastic, PVC plastic sheets, fiberglass, acrylic or polycarbonate. All parts of the protected side of the house is recommended also closed to reduce direct contact with the insect crop pests and diseases and to improve the growing environment conducive conditions for plant growth.
Means of lighting installations. Chrysanthemum plants require a certain length of days to keep growing vegetatively. The length of days required for the vegetative phase is more than critical limits (13.5 to 16 hours). In tropical areas like Indonesia, the length of day ranges of less than 12 hours (10 ½ hours effective with full intensity). Therefore, for the vegetative phase in the cultivation of chrysanthemums, the provision of additional light by using light at night is absolutely necessary.
The intensity of light to chrysanthemum plants at night ranged from 70-100 lux, or the equivalent incandescent lamp 75-100 watt or 40 watt TL with the distance between the light point 2 x 2 m and a height of 1.5 to 2 meters above the surface beds. The duration of additional light around 4-5 hours per day starting at 10:00 p.m. to 02:00 or at 23:00 to 03:00. To conserve electrical energy consumption, lighting should be arranged in cyclic life with 10 minutes and 20 minutes to die by using a timer or a timer. Distribution of time per hour is 6 segments. Electrical installation for lighting is constructed prior to planting seeds.
