How to plant Bletilla striata? Do a good job of field management and keep the soil moist
AbstractLand selection and soil preparation: Bletilla striata is generally planted around March, and loose, fertile sandy soil or humus soil should be chosen as much as possible. Propagation method: generally by tuber propagation. Planting method: before planting, trenches should be opened, with a spacing of about 20cm and a depth of about 5cm; the tubers should be placed with the buds facing up, and then covered with soil. Field management: during its growth period, related tasks such as regular weeding, keeping the soil moist, loosening the soil, fertilizing, and topdressing must be done well.
1. Land selection and soil preparation
Before planting Bletilla striata, the land must first be selected properly. It likes loose and fertile sandy soil or humus soil, and is very suitable for growing in warm, shady and humid environments, but it is very intolerant of cold. It is also very suitable for planting on hillsides with good drainage. When planting on hillsides, choose shady slopes for planting as much as possible.
When planting Bletilla striata, the soil must first be deeply plowed, about 20 centimeters of turning is generally needed, and fertilizer must also be applied or composting carried out at the same time. The amount of fertilizer applied is generally about 1000 kilograms per mu. Farmyard manure or ternary compound fertilizer is generally used. After fertilizing, the soil and fertilizer need to be thoroughly and evenly mixed, then the land should be shallowly plowed once before planting, and raised beds about 150 centimeters wide should be made.
2. Propagation method
When propagating Bletilla striata, tuber propagation can be chosen. This can not only support large-scale development, but tissue-cultured seedlings can also be used for propagation. If seed sowing is chosen, this effect cannot be achieved. When carrying out tuber propagation, Bletilla striata is generally dug out of the ground from September to November, and medium-sized tubers with more bud eyes and no diseases should be chosen as seeds as much as possible. After selecting the Bletilla striata to be used as seeds, dip them in wood ash and then planting can begin.
3. Planting method
Before planting, open trenches in the land. The trench spacing is about 20 centimeters, and the depth is about 5 centimeters. Then place the tubers in the trenches at a certain spacing, placing one tuber about every 10 centimeters. When placing the tubers, the buds need to face up, then cover the tubers with soil and compact the soil, then water and cover with grass. The soil moisture must be kept before emergence.
4. Field management
Field management mainly targets aspects such as intertillage and weeding, topdressing, irrigation, and drainage. For weeding, it needs to be done before Bletilla striata emerges. Generally, after the tubers are planted, acetochlor is sprayed on the ground. After the Bletilla striata seedlings are in the early stage, weeds will grow wildly again, and at this time a hoe must be used for manual weeding.
Bletilla striata is a plant that needs a great deal of fertilizer. Every month, farmyard manure or potassium dihydrogen phosphate, etc. need to be sprayed once. When irrigating Bletilla striata, it should be done together with drainage. It likes a moist soil environment, but it is also afraid of waterlogging, so when it is dry, water more, and watering can be arranged once in the morning and once in the evening.
