Description

Granular preparation for promoting aquatic weed to take root and leave and application thereof
Technical Field
The invention belongs to the technical field of aquaculture, and particularly relates to a granular preparation for promoting aquatic weeds to take root and grow leaves and application thereof.
Background
In recent years, the function of aquatic plants in the ecological and healthy aquaculture is more and more emphasized by people, the aquatic plants play an indispensable role particularly in the aquaculture of shrimps, crabs and special aquatic products, and the quality of the aquatic plants directly relates to the success or failure of the aquaculture. The aquatic health culture of aquatic plants mainly comprises the following components: (1) can provide rich bait. The fresh and tender aquatic weeds have the characteristics of rich nutrition, convenient ingestion, good palatability, no pollution and the like, and are favorite natural baits of river crabs, freshwater shrimps, herbivorous fishes and the like. (2) Can provide a hidden place for inhabitation. The aquatic weed can divide the water body of the pond into countless small spaces, so that good inhabitation and playing environments are provided for shrimps and crabs, the shrimps and the crabs are convenient to avoid the invasion of enemy organisms in the molting period, and the survival rate is improved. (3) Can purify water and improve substrate. The growth of the aquatic weeds can absorb a large amount of harmful substances, such as ammonia nitrogen, nitrite and organic decomposition products, which are continuously generated in water, so that the eutrophication of the water body is effectively prevented; the aquatic weeds can absorb some toxic substances and pollutants, and can be treated and purified, and the oxygen generated by photosynthesis can improve the oxygen content in water, thereby playing an important role in purifying water quality, improving substrate, ensuring fresh and stable pH value of water and improving water transparency. (4) Can be used for preventing and treating diseases. The aquatic weeds can release high-performance antibacterial substances, kill or inhibit pathogenic bacteria such as escherichia coli and the like in the water body, reduce the content of harmful microorganisms in the water body and reduce the morbidity. (5) Can be used for preventing heatstroke, cooling, preventing wind and cold. The aquatic plants are planted in the water body, so that the aquatic plants can prevent wind and cold in winter and shade sun and cool in summer, the water temperature can be adjusted, and the fish, the shrimp and the crab can be ensured to grow in a proper water temperature. The waterweeds mainly planted in aquaculture at present comprise waterweeds, hydrilla verticillata, eel grass, water peanuts and the like.
The nutrition required by the growth of the aquatic weeds comes from sediments at the bottom of the water body and water soluble substances, and the growth of the aquatic weeds is competed by the nutrition of phytoplankton in the water body. Meanwhile, the aquatic weeds are affected by water disturbance, and the root systems need to be thick, otherwise the aquatic weeds are not easily fixed on the underwater substrate and can float off the bottom. Therefore, the rooting and leaf growing of the aquatic weeds are very important.
In the prior art, nutrients for promoting the growth of waterweeds in aquaculture are mainly powdery or liquid fertilizers and partial granular fertilizers, mainly contain plant nutrient elements such as nitrogen and phosphorus, and the powdery and liquid fertilizers are dissolved in water after being used and can be utilized by phytoplankton, so that the utilization rate of the waterweeds is reduced; although the granular fertilizer can directly reach the root of the aquatic weeds, the main component of the granular fertilizer is a nitrogen-phosphorus fertilizer, and the granular fertilizer has poor effect of increasing the weight and thickening the root system.
