Propagation method: generally through tuber propagation. Planting method: before planting, ditch, keep the distance at about 20cm and the depth at about 5cm. The buds of tubers should face upwards and then be filled with soil.
Field management: during its growing period, it is necessary to do weeding, soil conservation, loosening soil, fertilization, topdressing and other related work regularly.
1, land selection and land preparation
Before planting Bletilla striata, you should first choose a good place. It likes loose and fertile sandy soil or humus soil, which is very suitable for growing in a warm and humid environment, but it is not cold-resistant. But also very suitable for planting in mountainous areas with good drainage. When planting in mountainous areas, try to choose shady hillsides for planting.
When planting Bletilla striata, the soil should be deeply ploughed, and it needs to be ploughed about 20 cm. At the same time, it needs to be fertilized or composted, and the amount of fertilization is about 1000 kg per mu. Generally, farmyard manure or ternary compound fertilizer is used as fertilizer. After fertilization, the soil and fertilizer should be fully and evenly mixed, and then turned over once before planting to make a high depression with a width of about 150 cm.
2. Breeding method
Bletilla striata can be propagated by tuber, which can not only develop in a large area, but also be propagated by tissue culture seedlings. If you choose the seeds you sow, you can't achieve this effect.
During tuber propagation, Bletilla striata is usually dug out of the ground in September-165438+10, and medium-sized tubers with many buds and no diseases are selected as seeds. Bletilla striata is selected as the seed and can be planted after being dyed with wood ash.
3. Planting method
Trenching should be done before planting, with a distance of about 20cm and a depth of about 5cm. Then, the tubers should be placed in the ditch at a certain distance, and one tuber should be placed every 10 cm. When placing tubers, the buds should face upwards, and then fill the tubers, compact them, water them, cover them with grass, and ensure the soil moisture before emergence.
4. Tian Tuan management
Field management mainly aims at intertillage weeding, topdressing, irrigation and drainage. Bletilla striata needs weeding before emergence. Generally, after tuber planting, acetochlor is sprayed on the ground. After the initial stage of Bletilla striata seedlings, weeds will grow wildly again. At this time, the hoe will be used for manual weeding.
Bletilla striata is a plant that needs a lot of fertilizer, and it needs to be sprayed with farmyard manure or potassium dihydrogen phosphate once a month. Bletilla striata should be washed and drained at the same time. It likes the humid soil environment, but it is afraid of waterlogging. When it is dry, it should be watered more, and it can be arranged to be watered once in the morning and once in the evening.
