NOVELTY - A greenhouse vegetable field planting fertilizer comprises 250-450 pts. wt. biocontrol membrane coated urea, 350-500 pts. wt. diammonium phosphate, 150-300 pts. wt. granular potassium sulfate. The bio-coated urea is urea granule of anti-coating agent; the coating of bio-control agent containing weathered coal and binder containing bio-control agent at mass ratio of 3.4:1; the weathered coal-containing bio-control agent comprising bio-control agent and weathered coal at mass ratio of 2:8-12; and the binder containing epoxy resin and bi-alkene tetramine at mass ratio of 1:1-1.3.    USE - Greenhouse vegetable field planting fertilizer used in planting hole or groove (claimed).    ADVANTAGE - The fertilizer provides a disease preventing function for field planting vegetable, prolongs fertilizer efficiency and avoids the damage to the root system.    DETAILED DESCRIPTION - A greenhouse vegetable field planting fertilizer comprises 250-450 pts. wt. biocontrol membrane coated urea, 350-500 pts. wt. diammonium phosphate, 150-300 pts. wt. granular potassium sulfate. The bio-coated urea is urea granule of anti-coating agent; the coating of bio-control agent containing weathered coal and binder containing bio-control agent at mass ratio of 3.4:1; the weathered coal-containing bio-control agent comprising bio-control agent and weathered coal at mass ratio of 2:8-12; the binder containing epoxy resin and bi-alkene tetramine at mass ratio of 1:1-1.3; the raw anti-coat film-forming agent is 4-9.6 wt.%; the bio-control agent is Trichoderma bio-control agent and Streptomyces bio-control agent; Trichoderma bio-control agent and Streptomyces bio-control agent is Trichoderma and Streptomyces, and prepared by Trichoderma harzianum solid culture and Streptomyces solid culture; and the Trichoderma strain comprising T. Viride or Trichoderma reesei, and Streptomyces strain comprising Streptomyces hygrospinosus. INDEPENDENT CLAIMS are included for: (1) a preparation of the fertilizer comprising using potato dextrose agar (PDA) culture medium to prepare Trichoderma inclined plane seed, preparing into Trichoderma inclined plane seed by sterile water, preparing into Trichoderma bio-control bacteria spore, inoculating suspension liquid in sterilized liquid culture medium at mass ratio of 3-6 wt.%, liquid culture medium formulation containing 200 g potato, 20 g glucose and 1000 g water; at 28 degrees C under 180 revolutions/minute, cultivating for 3-6 days to obtain Trichoderma seed liquid and bacterial liquid containing conidiophore, culturing, at 26-28 degrees C for 6-10 days, solid culture containing Trichoderma bio-control bacteria spore, culturing Trichoderma harzianum at 40-60 degrees C, grinding through 200 meshes sieve to obtain Trichoderma bio-control strain, Streptomyces bio-control agent; using PDA culture medium to obtain Streptomyces seed, washing Streptomyces seed by sterile water, preparing into Streptomycete conidiophore, and inoculating suspension liquid in sterilized liquid culture medium in mass ratio of 2-5 wt.%, feeding liquid culture medium formulation containing 20 grams of soluble starch, 1 gram of potassium nitrate, 0.5 grams of diammonium phosphate, 0.5 grams of potassium hydrogen, 0.5 grams of heptahydrate magnesium sulfate, 0.5 grams of sodium chloride,0.5 grams of heptahydrate ferrous sulfate; cultivating for 2-4 days at 28 degrees C of temperature, 200 revolutions/minute of rotation speed to obtain seed liquid, and Streptomyces bacterial liquid containing conidiophore; mixing rice flour, sorghum flour and rice hull at mass ratio of 2:2:3 to obtain solid material, sterilizing 1-3 wt.% solid culture medium at 28-30 degrees C for 8-12 days, taking Trichoderma bio-control agent, Streptomyces bio-control agent and weathered coal, mixing to obtain the bio-control agent of weathered coal, taking epoxy resin and bi-alkene compound, and uniformly mixing to obtain binder; and preheating at 60-70 degrees C in rotary drum, spraying adhesive preparation to rotary spraying urea particle, spraying layer of weathered coal containing bio-control agent, solidifying for 1-2 times to obtain bio-coated urea, mixing diammonium phosphate, granular potassium sulfate, and biocontrol membrane coated urea and obtaining the fertilizer; (2) application of the fertilizer comprising applying fertilizer in planting hole or groove during fixing vegetable in greenhouse, mixing with soil and culturing seedling.
