Abstract

The invention discloses a special fertilizer for transplanting tobacco, which is prepared from amino acid, potassium nitrate, potassium sulfate, ammonium dihydrogen phosphate, ammonium hydrogen carbonate, urea, humic acid, ferrous sulfate, ABT4 rooting powder, nicotine and soluble sugar. The special fertilizer is prepared by the steps of firstly, sufficiently mixing the amino acid, the nicotine and the soluble sugar to obtain mixed liquor; sequentially adding the ammonium hydrogen carbonate, part of the ammonium dihydrogen phosphate, part of the potassium nitrate, the urea and the ABT4 rooting powder into the mixed liquor for sufficient dissolution so as to obtain liquor A; sequentially dissolving the humic acid, part of the potassium nitrate, the potassium sulfate, part of the ammonium dihydrogen phosphate and the ferrous sulfate into water to obtain liquor B; and respectively packaging the diluted liquor A and the diluted liquor B for standby. The special fertilizer for transplanting the tobacco has the advantages that root system growth of tobacco strains is promoted, use rate of the fertilizer is increased, survival of tobacco seedlings is benefitted, pests after transplantation are decreased, the period of returning seedlings to a land for growing field crops is shortened, nutrient absorbing capacity of the tobacco strains is promoted, disease resistance and drought resistance of the tobacco strains are enhanced, the output of the tobacco strains is improved and the like.

Description

technical field [0001] The invention relates to a plant fertilizer, in particular to a special fertilizer for tobacco transplanting. Background technique [0002] The extensive promotion and application of balanced fertilization technology in the tobacco industry has greatly promoted the improvement of the yield and quality of tobacco leaves. However, most of the current balanced fertilization techniques only focus on the balance of nutrient requirements of tobacco plants throughout the growth period, but ignore the huge difference in nutrient absorption capacity of tobacco plants in different periods. Tobacco cultivation in my country generally adopts the fertilization method of combining fertilization before transplanting and topdressing after transplanting. In recent years, due to the increase in labor costs, one-time fertilization during transplanting has been adopted in some areas. The disadvantage of the above fertilization methods is that the utilization rate of fert...
