Problems solved by technology

[0003] The traditional breeding method is that after the razor clam seedlings are sown, the farmers use agricultural chemical fertilizers, such as ammonium bicarbonate, superphosphate (or urea, compound fertilizer), etc., to mix and sprinkle them into the pond, and use them as nutrients for razor clam-eating diatoms in seawater. , the nutrient composition of this method is single; and the fertilizer is mostly granular, which sinks into the pond soil after not being fully dissolved, causing soil quality to deteriorate; the nutrient utilization rate is low, and the algae multiply slowly, resulting in prolonged sea razor harvest period, increased cost, and low efficiency

Embodiment Construction

[0018] Below in conjunction with specific embodiment, the present invention is further described as follows:

[0019] First of all, it should be noted that the diatom liquid compound fertilizer of the present invention belongs to the special high-efficiency compound fertilizer for saltwater culture, and the species of algae fertilizing fertilizer used in the pond culture of sea razor clams in the prior art is single, resulting in insufficient algae nutrients; the fertilizer is not fully soluble in Water, causing fertilizer precipitation, low utilization rate, soil pollution, and sometimes too much fertilization based on experience can cause the death of sea razor clams. When sea razor clams are cultured at high density in ponds, traditional fertilization cannot cultivate high-density diatoms for feeding.

[0020] The present invention selects high-quality agricultural fertilizer, and is rich in nitrogen, phosphorus, silicon, iron and other trace elements to make a mixed liquid ...

Abstract

The invention discloses a diatom liquid compound fertilizer and a preparation method thereof. The diatom liquid compound fertilizer comprises nitrogen element, phosphorus element, silicon element, iron element and fresh water, wherein in per 1L of fresh water, the nitrogen mass concentration is 20%-25%, the phosphorus mass concentration is 3.5%-4.8%, the silicon mass concentration is 3.8%-5.2%, and the iron mass concentration is 0.4%-0.5%. Full dissolubility of the fertilizer is realized, the deposition rate is decreased, soil pollution is avoided, influences on water quality are avoided, andfast growth of razor clams is promoted.

Description

technical field [0001] The invention relates to the technical field of mariculture, in particular to a diatom liquid compound fertilizer and a preparation method thereof. Background technique [0002] Sea razor clam is a bishell marine product. Coastal tidal flats and reclamation ponds in Shandong, Guangxi and other provinces in China have natural growth or artificial breeding. Among them, the coastal ponds in Zhejiang, Fujian, and Guangdong are the most. Many coastal residents get rich by raising razor clams. , The road to employment. Because sea razor is rich in nutrition, it can be sold fresh and stored in a dry place. The market demand is large, and it has become a reality for farmers to raise razor in large-scale ponds. The density of sea razor culture in ponds is high, and a large amount of diatoms in seawater needs to be cultivated in order to meet the needs of sea razor. Ingestion, and a large number of diatoms in the cultivation pond must have sufficient nutrients ...
