The invention provides a method for cultivating pachyrhizua angulatus
tissue culture seedlings by means of
plant growth lamps. The method comprises the following steps of putting up a
greenhouse, determining and customizing the
plant growth lights, selecting a
seedling-raising substrate, selecting pachyrhizua angulatus
tissue culture seedlings, raising the seedlings and conducting
seedling-raising management. The
greenhouse adopts an ordinary
steel frame structure, one side of the
greenhouse is provided with a rolling gate used for being rolled up or laid down, and therefore the temperature in the greenhouse is adjusted; each
plant growth lamp adopts an LED of which the lamp head power is 3 W, and a 220 v
alternating current power supply is adopted to serve as a luminous source, wherein the ratio of red-light lamp heads to blue-light lamp heads is 7:2; the substrate is prepared from clean
loess, yellow sand and
organic fertilizer, the ratio of clean
loess to yellow sand to
organic fertilizer is 1 to 1 to 0.2, and the
organic fertilizer is prepared by evenly blending and fermenting sheep
manure,
chicken manure, peanut
bran and tea
bran according to the proportion of 1:1:0.5:0.2. The
survival rate of the pachyrhizua angulatus
tissue culture seedlings cultivated through the method is high, and compared with the situation that
seedling raising can be conducted only in February and March in the prior art, by means of the method, seedling raising can be advanced to be conducted from December of previous year, the peak that kudzuvine rhizomes appear on the market in a centralized mode is avoided, the economic benefit is improved, and the
time cost is reduced.
