The invention discloses a high-effective
fertilizer for improving greensickness resistance of tomatoes. The
fertilizer includes, by
mass, 0.1-0.5 parts of a sterilizing agent, 5-8 parts of a
traditional Chinese medicine agent, 2-4 parts of s-adenosylmetionine, 2-4 parts of
diammonium phosphate, 2-4 parts of
nitrohumic acid, 15-20 parts of
banyan leaves, 3-8 parts of soluble small-molecular
chitosan, 12-15 parts of chestnut shell
powder, 15-20 parts of
animal feces, 3-5 parts of
starch microspheres, 0.2-1 part of a microelement additive, 10-15 parts of
corncob, 2-5 parts of
zinc aminodithioformate, 1-3 parts of
borax, 1-3 parts of
magnesium sulfate, 1-3 parts of
potassium chloride, 20-30 parts of pond
sludge, 10-15 parts of
plant ash, 13-15 parts of rotten fruits, and 60-90 parts of water.In the invention, gibberellins, 24-epibrassinolide and
sodium hypochlorite are subjected to dispersion treatment under ultrasonic wave with the soluble small-molecular
chitosan and the
starch microspheres, thus producing the sustained-releasing
disease control factor which is easy to absorb and utilize. In the
fertilizer, the sustained-releasing
disease control factor can be absorbed and utilizedfor a long time during growth of tomatoes, thus avoiding increase of planting labor quantity due to repeated fertilization. Meanwhile, resistance of the tomatoes against the greensickness is improved.
