Problems solved by technology

In the process of cultivating benthic diatoms in large quantities, in addition to basic ecological factors such as light and temperature, nutrients such as nitrogen, phosphorus, iron, and silicon are also necessary for the growth of benthic diatoms, which play an important role in their nutrient metabolism. Can promote the rapid growth of benthic diatoms, but at present there is no method or reagent that utilizes the above-mentioned characteristics of benthic diatoms to treat and intervene in growth promotion

Abstract

The invention discloses a nutrition formula used for promoting rapid growth of benthic naviculaceae. The nutrition formula is characterized in that the nutrition formula comprises macroelements, microelements and vitamins, wherein the macroelements comprise nitrogen, phosphorus and silicon, the microelements comprise iron, zinc, copper, manganese, molybdenum and cobalt, and the vitamins comprise vitamin B1, vitamin B12 and vitamin H. According to growth characteristics of requirements of the benthic naviculaceae to different nutritive salts, the formula can achieve an objective of promoting rapid growth of purebred benthic diatom cultures. The nutrition formula has reasonable nutrition collocation, and is capable of effectively promoting rapid division growth of the naviculaceae, promoting absorption and utilization of a variety of nutrients, accelerating metabolism of naviculaceae cells and improving the production quantity.

Description

technical field [0001] The invention relates to a nutritional formula, in particular to a nutritional formula for promoting the rapid growth of benthic navicula. Background technique [0002] Artificially cultivated microalgae are the main food source for many animal larval development stages in aquatic ecosystems, and they can improve the nutritional value of animals. Marine benthic diatoms are an important natural bait for the feeding habits transformation of sea cucumber and abalone larvae, which can promote the attachment and metamorphosis of juvenile ginseng and abalone seedlings. In the process of cultivating benthic diatoms in large quantities, in addition to basic ecological factors such as light and temperature, nutrients such as nitrogen, phosphorus, iron, and silicon are also necessary for the growth of benthic diatoms, which play an important role in their nutrient metabolism. It can promote the rapid growth of benthic diatoms, but at this stage there is no meth...
