Tamarind belongs to the tourist banana family, with beautiful leaves and peculiar flower shapes. The potted tamarind is suitable for the environmental layout of conference rooms and halls, with a fresh and elegant feeling. The ground planted courtyards in the South increase the interest of natural scenery. So how is the crane hope orchid cultivated? What are the good methods in breeding? What should we pay attention to in breeding? Please read with me with questions!
Breeding methods of beautiful crane hope orchid (basic knowledge): the best breeding time: the planting time of crane hope orchid is generally from April to may or from September to October.
Best growth soil: loose and fertile garden soil, peat, a small amount of coarse sand and rotten organic fertilizer are often used to fully mix and prepare. It is advisable to use a high barrel basin for cultivation. The bottom of the basin should be padded with more tiles, and then paved with a layer of mixed matrix of ceramsite or broken rubble and culture soil, so as to facilitate drainage.
Growth humidity requirements: it is necessary to ensure the sufficient and regular water supply of crane hope. The soil should be kept moist in other seasons except from September to February when the plant needs to be kept dry.
The optimum growth temperature is 18 ~ 24 ℃ from March to October and 13 ~ 18 ℃ from October to march of the next year. 20 ~ 22 ℃ during the day and 10 ~ 13 ℃ at night are more favorable for growth. The temperature in winter shall not be lower than 5 ℃.
The best growth light: the daily light time of crane hope orchid shall not be less than 12 hours. Proper shade should be provided in summer, and sufficient sunshine is required in winter.
Matters needing attention for beautiful crane hope orchid breeding: fertilizer application: during the growth and development of crane hope orchid, thin cake fertilizer and water should be applied once every 2 weeks. 0.5% calcium superphosphate can be added to the fertilizer solution from the formation of flower stem to full flowering stage, which will make the flower color bloom more brightly. If you are not ready to leave seeds after flowering, you should cut off the residual flower stem in time to reduce nutrient consumption. Stop fertilization after mid October.
Key points of propagation: dividing plant method and sowing propagation are commonly used. 1. Branch propagation: it is often carried out in the middle and late April of spring. Select excellent and robust mother plants. Each cluster plant can be divided into 3 ~ 4 new plants, which should be divided along the natural boundary. Smear the wound with plant ash and sulfur powder, and then plant it immediately.
2. Sowing and reproduction: the seeds should be collected and sown when they are mature. Before sowing, the seeds can be rubbed in coarse sand to remove some of the outer seed coat, or treated with concentrated sulfuric acid, and then washed with clean water before sowing in the sand bed. The row spacing of the plants on demand is about 3 ~ 6cm, covered with sand of 0.5cm. The sowing period is often in the middle and late April. After sowing, the seeds are watered with enough water, covered with plastic cloth for moisture, and the radicle sprouts after 2 ~ 4 weeks, A few seeds may not germinate in the current year and can germinate in the next year. Generally, the upper pot planting is carried out when there are 5 ~ 6 leaves.
Key points of watering: the amount of watering depends on seasonal changes, plant growth and the actual dry and wet degree of soil. Generally speaking, watering should be dry and wet. Watering should be sufficient in summer. In spring and summer festivals, water should often be sprayed on the leaf surface and the ground around the flower pot, so as to improve the air humidity and create a cool environment, which is conducive to its growth and development. Reduce watering after late autumn and control watering in winter to keep the basin soil dry.
Basin soil replacement: generally, the basin should be replaced once a year at the seedling stage. After flowering, the pot can be changed once every 1 year. When changing pots, excavate the whole clumps of Strelitzia from the soil (with roots as much as possible). After the roots and the gap between buds can be clearly distinguished, reasonably select the cutting inlet according to the plant size and on the premise of ensuring that there are 2 ~ 3 buds for each small clump of ramets, and use a sharp knife to divide the mother plant into 2 ~ 3 clumps from the gap between rhizomes. The cut shall be stained with plant ash and dried in a ventilated place for 3 ~ 5 hours. The excessively long roots can be cut properly and planted.
Disease and pest control: the crane hope is prone to root rot, gray mold, bacterial wilt and anthrax. Before sowing, soak the seeds in warm water and disinfect the soil.
Experience of breeding crane hope orchid with excellent growth: 1. Shading in summer: in the south subtropical region, shading net is used to shade the crane hope orchid plant in summer, which can reduce the exposure and burns of plants and leaves by strong sunlight and high temperature, and maintain good plant growth. In summer, shading treatment could significantly reduce the primary flower rate of cut flowers. Because the market price of flowers in summer is low, and the price is only about 20% of the peak demand season, we should control the output of cut flowers in summer, reduce the market volume, and protect the plants to cross the summer smoothly, so as to improve the output and quality of cut flowers in the peak demand season in winter and spring. From the perspective of the economic benefits of the whole year, the gains outweigh the losses.
2. Winter shed: in the southern region of the province, the temperature is low from December in winter and spring to march of the next year, and there is often a cold wave in the north. The cut flower yield of crane hope is small. At this stage, the market demand for cut flowers increases and the price increases. The results showed that the measures of building film arch shed in the field could significantly improve the yield of cut flowers, especially the effect of small arch shed was the best, and the yield of cut flowers increased by 300% compared with that in the open field. The simple film small arch shed has the advantages of easy material acquisition and covering, low cost, good heat preservation and flower promotion effect, and is suitable for the majority of rural planters.
