Organic and inorganic multi-element water-soluble water flush fertilizer for glasshouse culture and preparation method thereof

Abstract

The invention relates to an organic and inorganic multi-element water-soluble water flush fertilizer for glasshouse culture. The fertilizer comprises the components in part by weight: 20 to 40 parts of sodium ligninsulfonate, 10 to 20 parts of urea, 15 to 20 parts of potassium chloride, 30 to 40 parts of ammonium sulphate, 3 to 7 parts of monoammonium phosphate, 1 to 2 parts of magnesium sulfate, 1 to 2 parts of zinc sulfate, 0.5 to 1 part of borax, 1 to 2 parts of calcium nitrate, 0.4 to 1 part of compound chelator and 0.4 to 1 part of acidity regulator, wherein the organic substances account for 15 to 20% of the gross weight, the combination of nitrogen, phosphorus, potassium nutrients account for 70 to 75% of the gross weight, and the secondary and micro elements account for 5 to 10% of the gross weight. In the implementation, at first, sodium ligninsulfonate is dissolved, then is chelated with various secondary and micro-element fertilizer raw materials and is treated through cooling crystallization, and a large amount of secondary and micro-element fertilizer raw materials are added, the smashing and the packing are conducted, and finally the organic and inorganic multi-element water-soluble water flush fertilizer is manufactured. The fertilizer can be rapidly dissolved in the water, is used in coordination with a drop-irrigation and spray-irrigation device, contains comprehensive nutrition and the nutrition proportion suitable for vegetable growth, can achieve the water and fertilizer coupling, and promotes the good quality and high yield of vegetable crops. The invention has the advantages that the composition mixture ratio is reasonable, and the preparation method is simple.

Description

technical field

[0001] The invention relates to a water-soluble flushing fertilizer and a preparation method thereof, in particular to an organic-inorganic multi-element water-soluble flushing fertilizer for greenhouse cultivation and a preparation method thereof. Background technique

[0002] In recent years, with the development of my country's "two high and one excellent" agriculture and the protected cultivation of protected agriculture has developed rapidly. At present, in the production of protected areas, the method of irrigation and fertilization of vegetables in greenhouses is mostly used in irrigation and fertilization. method, due to the poor solubility and slow dissolution rate of existing fertilizers, most of them remain on the soil surface, or the way of flushing is unreasonable, or due to the strong volatility of fertilizers, it not only causes a lot of waste of fertilizers and water resources, but also reduces the utilization rate of chemical fertilizers. , but...
