The invention discloses a muskmelon
seedling growing substrate, and belongs to the technical field of
seedling growing substrates. The muskmelon
seedling growing substrate is prepared from thoroughly-decomposed maize
straw, thoroughly-decomposed chicken dung, turfy soil,
vermiculite, antagonistic actinomycetes and
chitosan, and the
mass ratio of thoroughly-decomposed maize
straw to thoroughly-decomposed chicken dung to turfy soil,
vermiculite to antagonistic actinomycetes to
chitosan is 1:(0.08-0.12):(0.8-1.2):(0.8-1.2):(0.04-0.06):(0.06-0.1). According to the muskmelon seedling growing substrate, the substrate contains antagonistic actinomycetes, the antagonistic actinomycetes has the good
colonization capability in
rhizosphere soil, the good inhibiting effect is achieved for
greenhouse soil-borne diseases, and the
continuous cropping obstacle can be effectively repaired; the PPO activity of muskmelon seedling stage leaves and roots is improved, and the muskmelon
plant disease resistance is improved; the substrate is a compound substrate, the substrate is loose and good in
water binding capacity, the total-P, total-K, quick-acting N, quick-acting P and quick-acting K contents arehigh, the fruit quality can be improved, and the fruit yield can be increased.
