The invention discloses a green biological
seedling raising matrix, relating to the
seedling raising matrix technology. The preparation method comprises the following steps of: mixing
straw powder,
organic fertilizer and
nutrient soil to be uniform, adding water until the
water content is 45-55%, adding compound
bacteria and then mixing to be uniform, stacking for fermenting, turning when the temperature increases to 50 + / - 2 DEG C, turning and cooling for 1-2 days when the temperature is increased to 50 DEG C again, adding microelements and
growth hormone, stirring to be uniform, and packaging. The invention has the beneficial effects that: (1) the matrix is rich in organic matters and beneficial biological germs, has comprehensive
nutrition and is loose and soft; (2) the matrix is seed-saving and labour-saving and can shorten
seedling raising period; (3) the matrix can be used to ensure uniform and strong seedlings and high sprout rate; (4) the matrix can protect roots and hold water and
fertilizer and has good air permeability; (5) the matrix has the functions of promoting flower
bud differentiation and improving the yield; and (6) the matrix has the effect of resisting soil diseases. The matrix disclosed by the invention is applicable to seedling raising of vegetable, melon and fruit, flower and
plant, tea, tobacco and cotton.
