Embodiment 1
[0025] A cultivation method of yam, comprising the following steps:
[0026] 1) Site selection and preparation
[0027] Choose weakly acidic or neutral land with loose and fertile soil and good drainage, plow 50 cm deep in winter, apply 2000-2200 kg of farm manure and 500-800 kg of decomposed straw fertilizer per mu during plowing, and plow and harrow after the next spring Fine, when plowing, apply 20 kg of urea, 50 kg of phosphorus and potassium fertilizers per mu, 1.2 to 1.5 meters wide and 10 to 15 cm high, and cover the furrow with black film.
[0028] 2) planting
[0029] The planting time is the first ten days of April. Dig out planting holes with a plant spacing of 20 cm x 30 cm and a depth of 5 to 7 cm on the furrow surface, fill the holes with human and livestock manure and dry them, and then place the selected reed heads in the same direction. Put it flat in the ditch, backfill the poisonous field soil mixed with carbendazim and mancozeb 2 to 3 cm, and then fill th...

Abstract
The invention discloses a cultivation method for Chinese yam. The cultivation method comprises the following steps: (1) field selecting and preparing, namely, performing deep ploughing in winter after a field is selected, plowing and raking the field at the beginning of spring, ridging, and covering a ridge surface with a black film; (2) planting; (3) covering; (4) field management; (5) pest preventing and controlling, namely, preventing and controlling according to incidence. According to the cultivation method, after the basal parts of stems of the Chinese yam are planted, straw matting is adopted for covering and insulating heat, which replaces the traditional plastic film, and has the advantages of being economic and environment-friendly; the straw can be reused, so that the investment cost is reduced, and the economic benefit is improved; after seedlings come out, a low and short bracket is erected; through the combination of the bracket and the straw matting for insulating heat, the investment cost is reduced compared with the existing plastic greenhouse; moreover, the bracket is low, so that the impact force of wind to a greenhouse frame is low; therefore, the cultivation method can be applied to the environment with strong wind in north-west.
Description
technical field [0001] The invention belongs to the technical field of cultivation of Chinese medicinal materials, and in particular relates to a cultivation method of yam.
