Description
Technical Field
The invention relates to the technical field of fertilizers, in particular to a special set of fertilizer for satsuma mandarin and application thereof.
Background
The orange varieties have abundant resources, including wide-peel oranges, pomelos, lemons, oranges and the like. The citrus with wide peel has various varieties, the main cultivated variety is the wenzhou mandarin orange, and the citrus with wide peel becomes a variety with the widest planting area due to the characteristics of good stress resistance, wide adaptability, high and stable yield and the like. However, most fruit growers lack scientific planting management experience, and planting households have the problems of blind fertilization and unreasonable fertilizer proportioning application, so that the fertilizer utilization rate is low, the production cost is high, and the fruit quality is poor.
In recent years, CN 20071011393.X discloses a special controlled release fertilizer for oranges and a preparation method thereof, and the invention is to precisely compound thermoplastic resin coated urea, sulfur coated urea, potassium sulfate compound fertilizer, potassium sulfate, diammonium phosphate, zinc sulfate and borax according to a fertilizer requirement rule of the oranges to form the special formula controlled release fertilizer for the oranges, so that the absorption utilization rate of the fertilizer is improved. However, the resin coated urea and the sulfur coated urea adopted by the method have high economic cost, and can increase the use burden of fruit growers; meanwhile, the coating material is difficult to degrade, which causes soil pollution and is not beneficial to environmental protection. For example, CN 201010204644.4 discloses an organic compound fertilizer containing citrus pulp dedicated for citrus and a preparation method thereof, which adopts the technical scheme that organic matter, urea, monoammonium phosphate and potassium sulfate are used as raw materials, the organic matter is fermented, then the urea, monoammonium phosphate and potassium sulfate are added according to the proportion of nitrogen, phosphorus and potassium elements in the total mass, and the mixture is subjected to insect killing, sterilization, granulation, drying, cooling, screening and coating.
Therefore, how to provide a wenzhou mandarin orange fertilizer which is environment-friendly, has the advantages of quality improvement and efficiency improvement, low economic cost and good weight-reducing effect becomes a technical problem to be solved in the field.

The invention firstly provides a wenzhou mandarin orange package fertilizer which comprises the following components: germination fertilizer, fruit strengthening fertilizer and fruit picking fertilizer;
in the germination fertilizer, the mass ratio of nitrogen element, phosphorus pentoxide and potassium oxide is 20-24: 6 to 10:13 to 17;
in the fruit-strengthening fertilizer, the mass ratio of nitrogen element, phosphorus pentoxide and potassium oxide is 13-17: 3 to 7:18 to 22;
in the fruit picking fertilizer, the mass ratio of nitrogen element, phosphorus pentoxide and potassium oxide is (14-18): 11 to 15:6 to 10.
The invention discovers that the nutrient requirement rules of different citrus varieties are different due to the difference between the different citrus varieties. For planting satsuma mandarin, the general fertilizer special for the satsuma mandarin can cause mismatching of nutrient input quantity and fruit tree demand quantity, so that the satsuma mandarin has poor fruit quality and yield, cannot play a role in improving quality and efficiency, and can also cause nutrient waste.
The application provides the citrus unshiu package fertilizer for different growth stages of citrus unshiu by researching the absorption characteristics of nitrogen, phosphorus and potassium nutrients in each growth stage of the citrus unshiu and fully considering the soil nutrient supply characteristics. In the germination fertilizer, the fruit strengthening fertilizer and the fruit picking fertilizer, the mass ratio of nitrogen element, phosphorus pentoxide and potassium oxide is respectively controlled in the mixture ratio, so that the wenzhou mandarin orange has the most suitable chemical nutrient dosage in different growth stages, the problems of poor fruit quality and yield and chemical nutrient waste caused by excessive chemical nutrients are solved, and a better fertilization effect is obtained when less fertilizer is applied in the whole growth period of fruit trees through the synergistic effect of the fertilizer nutrients in three stages, so that the quality-improving and efficiency-improving effects are remarkable, and the economic cost is low.

TABLE 2 comparison of field test results for different fertilizer products
Note: the difference between treatments is marked by different lower case letters in the same column (P < 0.05)
Yield increase (%) = (example yield-control yield)/control yield × 100%;
soluble solid increase rate (%) = (soluble solid content of example-soluble solid content of control group)/soluble solid content of control group × 100%.
Vc increase rate (%) = (content of Vc in example-content of Vc in control group)/content of Vc in control group × 100%.
As can be seen from table 2, compared with the conventional fertilizer products for farmers, the satsuma mandarin orange set fertilizer product prepared in example 1 promotes 11.7% of yield increase, 21.3% of Vc increase and 8.5% of fixable increase. The citrus unshiu package fertilizer prepared in example 2 improves the yield by 5.0%, increases Vc by 8.0% and can improve solid content by 2.8%. The citrus unshiu complex fertilizer prepared in example 3 promotes the yield to be increased by 10.3%, the Vc to be increased by 15.7% and the solid content to be increased by 10.4%.
Although the invention has been described in detail hereinabove with respect to a general description and specific embodiments thereof, it will be apparent to those skilled in the art that modifications or improvements may be made thereto based on the invention. Accordingly, it is intended that all such modifications and alterations be included within the scope of this invention as defined in the appended claims.
