2. Perfume orchids can be cultivated outdoors and on the balcony in spring, summer and autumn. It is required to choose a place with good ventilation, moist air and no environmental pollution. It is best to be close to ponds and rivers, and at least install trees or bamboo forests and sunshade nets to reduce sunlight and temperature. It is best to put the basin on a wooden frame or steel frame. If the floor is to be bricked, the balcony at home can also be bricked on a small tin can to increase the humidity.
3, perfume orchids are mostly semi-shaded plants, most varieties are afraid of direct sunlight and need proper shading. Perfume orchids can be opened in the first half of April, and more sunshine can promote their growth. In May, in addition to the sunshine at noon, you can receive 6 hours of light. It has been cloudy all day since June. After 10, except Zhongyang, it can be fully opened for maintenance. Remember this proverb: "leafy shade is good, and more sunshine is good." Visible shading is very important.
4, perfume orchids eat "vegetarian", fertilization depends on the selected pot soil and growth. All perfume orchids that are flourishing and disease-free can be fertilized, and those that are not growing well should not be fertilized or fertilized in small quantities. A new orchid with incomplete roots needs 1-2 years to be fertilized. Generally, in June and July, when the leaf buds of orchids are about 1.5 cm long, the decomposed liquid fertilizer should be applied once every three weeks (the concentration should be around 10%). Perfume orchids should not use chemical fertilizers. If it is not suitable for fertilization in high temperature season, dilute fertilizer can be applied every two to three weeks from August to September. Perfume orchids should be fertilized at night and watered in the morning every time. This is called backwater.
5, perfume orchids should be watered with rain and spring water, tap water or rice washing water overnight. When you pour it, pour it from the edge of the basin, not into the bud. The amount of watering should be determined according to the temperature, the degree of dryness and wetness of the basin soil and the growth of bluegrass. Most of the leaves are watered, and the thin leaves are watered less. From April to May, the new buds haven't grown soil yet, so the soil in the basin should be dry, and the new buds will rot easily if they are too wet. June-September is the growth period of orchid buds, so it is necessary to increase the amount of watering. Water it once every morning on sunny days, and don't water it in the hot sun at noon. To reduce water consumption in autumn, foliar water spraying can be used to keep the basin soil moist, and water consumption can be controlled to keep "80% dry and 20% wet" in winter.
6. In the process of cultivating perfume orchids, you should always cut off dead yellow, broken leaves and diseased leaves to facilitate ventilation. If there are too many flower buds, only strong buds are left, and it is appropriate to have 1-2 flower buds per pot. Chunlan should be picked half a month after flowering, and rare orchids should be picked seven days later. The leaf buds in spring thrive and create the beauty of the next year. The last flower of the preface to Sharon was cut 3 cm away from the surface of the basin one week after flowering.
