Embodiment 1

[0040] The high-yield cultivation method of bletilla striata comprises the following steps:

[0041] A. Site selection and site preparation:

[0042] Choose sandy loam soil with deep soil, fertile, loose, well-drained, and rich in humus as the planting soil of Bletilla striata. The nutrient status of the planting soil is: the organic matter content of the plow layer soil is 30-50g / kg, and the available nitrogen is 0.04g / kg-0.1 g / kg, available phosphorus 0.005g / kg~0.02g / kg, available potassium 0.02g / kg~0.15g / kg, pH 5~7.

[0043]Before planting, plow 20-30cm, apply 10kg of urea per mu, 60kg of superphosphate, 3kg of potassium sulfate, and 0.25kg of ammonium molybdate.

[0044] B. Selection:

[0045] Choose the tubers of Bletilla striata that were born in the same year, and it is required to be free from insects and injuries. Cut the tubers into small pieces, each with 1 to 2 buds.

[0046] C. Planting:

[0047] Plant bletilla striata from February to March, dig nests on the ...

Abstract

The invention discloses a cultivation method for bletilla striata at high yield. The cultivation method includes the following steps of land selection and preparation, seed selection, planting, field management, harvesting and disease and insect pest prevention and treatment. In land preparation, 10-12 kg of urea, 60-70 kg of calcium superphosphate, 3-4 kg of sulfuric acid and 0.25-0.35 kg of ammonium molybdate are applied per mu; during growth of the bletilla striata, in topdressing, 45-55 kg of urea, 15-18 kg of potassium sulfate, 2.5-3.5 kg of zinc sulfate and 2.5-3.5 kg of borax are applied in total by several times; the bletilla striata is planted from February to March, and corn is planted in reserved rows from April to May. The cultivation method has the advantages that the fertilization proportion of nitrogen phosphorus and potassium, zinc fertilizer, boron fertilizer and molybdate fertilizer is reasonably formulated, so that the optimal combination of the yield and quality of the bletilla striata is achieved; according to the growth period of the bletilla striata and the corn, the plant of topdressing is arranged so that the yield and the quality can be improved; the bletilla striata and the corn are planted in a reasonable match mode, so that land resources are efficiently utilized.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine cultivation, in particular to a high-yield cultivation method for bletilla striata. Background technique [0002] Bletilla striata is a perennial herbaceous plant of Orchidaceae, with a plant height of 18-60cm. The primary pseudobulb is spherical and grows to a certain extent to form a V-shaped massive pseudobulb. The flowering period is from April to May, and the fruiting period is from July to September. [0003] Bletilla striata likes a warm, damp environment, such as the undergrowth of a wild valley. It is slightly cold-tolerant and can be cultivated in the open field in the middle and lower reaches of the Yangtze River. Strong shade tolerance, avoid strong direct sunlight, and the leaves are easy to wither and turn yellow during high temperature and drought in summer. It is suitable for well-drained sandy loam soil with a lot of humus. It often grows in relatively humid stone wal...
