Problems solved by technology

[0002] At present, fertilizers for pear trees generally do not have a slow-release function. In addition, the nutrient elements of fertilizers are not comprehensive, which leads to the ineffective absorption and utilization of fertilizers during the growth of pear trees, resulting in malnutrition in the later stage. In addition, reasonable adjustments to the fertilization process are also required during the fertilization process. Timing, resulting in nutrient imbalance and low fertilizer uptake and utilization, resulting in low pear tree yields

Abstract

The invention discloses a fertilizer special for pear trees. The fertilizer comprises the following components in parts by weight: 60-80 parts of urea, 15-35 parts of starch, 20-30 parts of formaldehyde, 10-20 parts of potassium dihydrogen phosphate, 15-30 parts of potassium sulfate, 5-15 parts of borax, 10-15 parts of ferrous sulfate, 10-15 parts of zinc sulfate, 5-15 parts of sodium molybdate, 5-15 parts of magnesium sulfate, 40-50 parts of calcium superphosphate, 2-5 parts of a resin coating agent, 2-10 parts of a curing agent, and 100-200 parts of water. According to the fertilizer special for pear trees disclosed by the invention, by virtue of adding the resin coating agent, the fertilizer can obtain the slow-release function so that growth nutrient elements supplied to pear trees are slowly released from various elements in the fertilizer in stages. The invention also provides a preparation method of the fertilizer. The method is simple and feasible and suitable for large-scale implementation. By virtue of applying the fertilizer disclosed by the invention to induce the fruit setting, the fruit setting rate of pear trees reaches 80.33%-88.56%.
