The invention relates to a
greenhouse watermelon yield-increasing special
fertilizer. In percentage by weight, the special
fertilizer consists of 18 to 37 percent of soybean cake
powder, 8 to 16 percent of broomcorn cake
powder, 16 to 25 percent of dried sheep
manure, 10 to 16 percent of soybean stem
powder, 6 to 10 percent of dried
chicken manure, 4 to 9 percent of white
sugar, 4 to 9 percent of dried duck
manure, 1 to 2 percent of rock candy, 0.5 to 1 percent of dipterex, 1 to 2 percent of superphosphate, 1 to 2 percent of grass ash and 0.5 to 1 percent of
potassium sulfate. According to a proportion, all the first eight raw materials are put into a mixer together and mixed for 100 minutes before being taken out, the raw materials are then put into a grinder and ground into 200-mesh particles, the particles are taken out and then uniformly mixed with the dipterex, the superphosphate, the grass ash and the
potassium sulfate, the particles are then put into the mixer again and mixed for 50 minutes before being taken out, a
molding machine is used for molding the particles into a cylindrical
greenhouse watermelon yield-increasing special
fertilizer column which is 250g, and the yield-increasing special fertilizer column needs to be compacted and tamped and cannot be easily broken when being held by the hand.
