The results show that: the normal growth and flowering of Hanlan need comprehensive nutrients, and soilless cultivation is difficult to meet the growth needs of Hanlan, in order to get the supply from the mixed mountain mud, the growth is better.
Hanlan mostly grows in the broad-leaved forest with steep slopes and dense forests, with little light, shallow foundation and good water permeability. Because of this, when planting, choose high foot purple sand basin, one third of the basin bottom is made of coarse-grained bricks and porous materials. Planting requires looseness, air permeability, water utilization and warmth preservation.
There are differences in the growth of Hanlan, so the cultivation methods should be slightly different. One is opacity. Pay attention to shade and replenish water. Every morning or night, spray the scattered water on the leaves, and the shading degree is about 80%. Such leaves are glossy and have few diseases. Second, they are windproof and antifreeze. For a period of time in autumn and winter, the strong wind shall be prevented, and the frost damage date shall be covered with heat preservation. Third, apply fertilizer. In general, Hanlan can be used with less fertilizer, and can also be sprayed with chemical fertilizer containing phosphorus and potassium during April June and August October.
It is not suitable to plant Hanlan under too strong light. Excessive shading or long-term indoor storage will affect the photosynthesis of orchids and cause poor growth. Under the premise of not burning the orchid leaves, more sunlight should be seen properly.
Try to make the basin soil moist but not wet, slightly dry but not dry. Cold orchid is planted with the prepared culture soil, generally 8-15 days in late spring, 4-6 days in summer and 4-10 days in autumn. In winter, it can not be watered for more than a month. More seedlings are planted in large pots and less in small pots. Basin soil to see the dry see wet, pouring that is, usually slightly dry as a principle, so that the root system of Hanlan developed, robust growth.
Hanlan likes the basin soil to be slightly dry, and the air humidity is large. Therefore, a suitable relative humidity should be created for planting Hanlan. The air humidity is high, the growth is good, easy to raise the top-grade seedlings with full closed tip.
Hanlan needs fresh air and pollution-free growth environment. All people feel fresh air, no smoke, less dust, no smell, good ventilation environment are suitable for orchid. All the water that people can drink can be used for watering orchids.
Cultivate the strong seedlings of Hanlan ripe grass, and add a small amount of base fertilizer when changing pots. In order to balance the nutrients, the application of lean organic fertilizer can be increased once a month from April to June and from September to October, but it should be remembered that it is better to be light than to be thick to prevent fertilizer damage.
It is the key to eliminate the pests, disease sources and infectious sources thoroughly. Destroy in time and burn the sick plant. Secondly, the cultivation of Hanlan must be potted on the shelves, so easy to manage, less pollution, fewer pests and diseases. Spray at the right time, generally from March to may in spring and from October to November in autumn. Spray once a month for the rest of the time.
Try to stop being impatient and nurturing orchids. Be patient. That is, "one year to see flowers, two years to see seedlings, three years to see pots", that is, in a short period of time, "total annihilation". Orchid is universal in human nature. You know her and love her. She will naturally sprout every year, spit out fragrance every year, and give you rich rewards. To spoil, coddle, or be eager for success is not allowed.
