Abstract
A preparation method of a special chemical fertilizer for strawberries in a greenhouse comprises the following steps: step one, adding zinc-containing rape seed cakes, an organic nitrogen fertilizer, an organic phosphorus fertilizer, an organic potassium fertilizer and a trace-element fertilizer in a stirring machine, and stirring the components to obtain a first mixture; step two, heating the first mixture in a sealed manner to obtain a second mixture; step three, taking out the second mixture and composting the second mixture, turning and throwing the second mixture by a turner, and heating the second mixture to obtain a third mixture; step four, pulverizing the third mixture by using a pulverizer, granulating the third mixture by a granulating machine, placing the third mixture in a sterilizing box and sterilizing the third mixture at high temperature, then adding water in the third mixture and heating the third mixture to obtain slurry, and drying the slurry to obtain a chemical fertilizer coarse product; and step five, sieving the chemical fertilizer coarse product by using a sieving machine, and packing and storing the product to obtain the special chemical fertilizer for strawberries in the greenhouse. The special chemical fertilizer for strawberries in the greenhouse is prepared from waste organic fertilizers; the cost is reduced; moreover, the chemical fertilizer is economical and environmentally friendly; and the applicability of the growing strawberries is high.
Description
technical field [0001] The invention belongs to the technical field of vegetable and fruit planting fertilizers, and in particular relates to a preparation method of a special chemical fertilizer for greenhouse strawberries. Background technique [0002] Strawberry is a red fruit, a perennial herb with a heart-shaped appearance, delicious red and tender, juicy pulp, sweet and sour, and has a special rich fruit aroma. It is of high value, rich in vitamin C, and has the effect of helping digestion, so it is known as the "Queen of Fruits". At present, most of the fertilizers in strawberry planting are configured by farmers themselves. Such extensive preparation will lead to poor control of the elements in the fertilizer and the ratio of each element, which will not achieve the optimal effect, lead to waste of fertilizers, and cause strawberries. The adverse consequences of low yield, poor taste and poor economic benefits. [0003] Zinc is a kind of trace element, the content ...
