Preparation method of special fertilizer for nursery stock transplantation

Abstract

A preparation method of a special fertilizer for nursery stock transplantation comprises the following steps: 1, mixing fly ash with crop straws, fermenting the obtained mixture in a fermentation tank, removing the fermented material, drying the fermented material, and mixing and granulating the dried fermented material, monoammonium phosphate and potassium selenite to obtain grains 1; 2, drying young tangelos in the sun, drying the young tangelos, crushing the dried young tangelos by a crusher, adding an ethanol solution with the concentration of 50% according to a solid-to-liquid ratio of 1:20, stirring the crushed young tangelos and the ethanol solution, filtering the obtained solution to obtain an ethanol extract, and evaporating the ethanol extract until the ethanol extract is dry in order to obtain a powder 1; 3, calcining rice husks in a closed environment to obtain carbon powder, adding water to immerse the carbon powder, filtering the obtained solution, adding water and the powder 1, adding dimethyl formamide, methyl jasmonate and sodium alginate, heating the obtained solution for a period of time, cooling the heated solution, filtering the cooled solution, and drying the filtered solution to obtain a material 1; and 4, mixing the granules 1 with the material 1, and carrying out extrusion molding by using a heat sealer to prepare the special fertilizer for nursery stock transplantation. The special fertilizer can well reduce the loss of water in newly transplanted nursery stocks, keep good growth vigor of the newly transplanted nursery stocks and improve the survival rate of the newly transplanted nursery stocks.

Description

technical field [0001] The invention belongs to the technical field of plant fertilizers, and in particular relates to a preparation method of a special fertilizer for seedling transplantation. Background technique [0002] With the development of specialization, industrialization and scale of planting in our country, its requirements for fertilizers are constantly upgrading, while traditional fertilizers have restricted the sustainable development of planting industry due to their low nutrient utilization. The application of coated fertilizer is an effective way to solve this problem. However, at present, the coating materials of common coated fertilizers are mainly chemically synthesized non-degradable polymers, which are easily left in the soil and cause soil degradation and pollution. At the same time, the coating materials have a single function and usually only have slow and controlled release. The effect does not take into account the functions of water absorption, a...

Problems solved by technology

They have made great progress in prolonging the fertilizer effect through the application of several coating materials, but they are still mainly composed of nitrogen, phosphorus, potassium and other large elements, which cannot well meet the needs of seedlings for medium and trace elements, and need to be supplemented separately. Increase the cost of fertilization, and at the same time, it is impossible to make corresponding adjustments to the physiological conditions of plants, soil quality and water source environment

Patent No. ZL200610161312.6 provides a special fertilizer applied on seedlings, which is characterized in that the special fertilizer is mixed with ammonium sulfate, monoammonium phosphate, superphosphate, potassium sulfate, sulfur, ferrous sulfate, and malathion according to the ratio. Evenly formed, although it has the effect of promoting roots, preventing diseases and insects, but because it is basically based on chemical fertilizers, the fertilizer effect time is short, the added value is low, and it needs to be applied multiple times, which is labor-intensive, time-consuming and laborious, and the cost of fertilization is high.
