In winter, the water temperature gradually decreases with temperature. Farmers sell crabs and clear the pond to prepare for the next year's production. The first problem everyone faces is how to make water.
The first thing to understand is what is fertilizer?
The real meaning of fertilizer is that there are healthy, strong metabolic capacity in the aquaculture water, and a sufficient number of beneficial algae (such as green algae, diatoms, etc.). Many people know fertilizer, but do not know why winter fertilizer is so important for shrimp and crab farming?
First, fertilizers and waters are rich in floating plants and animals, providing natural open bait for shrimp and crab seedlings and strengthening their seedlings.
Second, phytoplankton can produce enough dissolved oxygen to ensure the respiration of seed.
Third, phytoplankton can effectively reduce ammonia, nitrite and other harmful substances through photosynthesis and reduce damage to seedlings.
Fourth, fertilizer and water can effectively inhibit the outbreak of moss, promote the growth of aquatic plants, and provide natural shelters for seedlings.
Fifth, fertilizer and water can stabilize various water quality indicators of the water and reduce the stress response of the seed. Taking PH as an example, the pH range of the thin water body fluctuates to a large extent and extreme conditions occur. PH is too low, shrimp and crab vitality decreased, PH is too high, alkaline burning shrimp and crab, showing poor eating.
In short, the winter fertilizer can provide excellent growth environment for the seed, directly increase the seed size and survival rate after spring, so that the year's breeding will win on the starting line!
The difficulty of winter fertilizer?
Winter fertilizer has a series of constraints:
First, the water temperature is low, and each type of phytoplankton has a corresponding optimum growth temperature. Below this temperature, the enzyme activity in the body is decreased, and the metabolic rate is decreased. The direct expression of algae is slow and the water body is not fat.
Second, light intensity is weak, and photosynthesis is directly reduced. Algae cannot absorb enough energy to synthesize organic substances that are necessary for them, and eventually reduce cell mitosis.
Third, there is a lack of algae species. After clear ponds in the winter, and particularly disinfectants such as bleaching agents, the only algae species are also lost. Water without provenance cannot be fattened anyway.
Fourth, ponds contain certain limiting factors, such as heavy metals. Everyone knows that copper sulfate has a good effect on cyanobacteria, but its side effects are very large. One of them is that the residue is very serious, and it suppresses algae breeding for years.
Fifth, in the absence of strains, after the drying ponds in the dry ponds, after disinfection and sterilization, the flora at the bottom of the ponds is severely damaged and can not continuously provide nutrients for the water bodies.
Sixth, improper fertilizer selection, a single inorganic fertilizer composition, the effect of fertilizer and water instability, fast fade. Traditional organic fertilizers, which are slowly fattened, can severely consume dissolved oxygen in the water, which can easily lead to an increase in ammonia nitrogen subsalts and the outbreak of zooplankton and further damage the water body. Biofertilizers have stringent fermentation technology requirements. If non-compliance products are selected, the effect of fertilizer and water will be greatly reduced.
solution
According to the constraints of fertilizers, a set of fertilizer and water programs is summarized here, divided into three parts. It needs to be emphasized that, in the specific practice process, appropriate steps can be selected for different Tangkou conditions.
First, create beneficial fertilizer and water conditions. After clear ponds were planted with Elodea, sunny days with more than 3 days were selected to raise the slope water level to 50-60cm. Introduce some fresh sources of algae from the outside of the pond, 2cm thick.
Second, eliminate unfavorable factors. Use water protection treasure, the active ingredient is a high concentration of organic acids, 4 acres meters / bottle, complex with heavy metal ions remaining in the water, remove fertilizer and water limiting factor.
Third, rational use of fertilizer and water packages. 1 bottle of quick-fertilizer + 1 packet of Feishuibao + +1 bottle of bacteria-producing treasure, soaked in the cabin with pool water overnight, Quanchiposa, use 10-15 acres of rice. The shrimp and crab ponds are planted with water and plants. Considering that the plants absorb some of the fertilizer, the dosage can be increased appropriately.
Fast Fertilizer, Fei Shuibao use high quality raw materials, scientific ratio, rich in amino acid nitrogen, available phosphorus, potassium fulvic acid, all-soluble organic carbon, fertilizer and water bacteria group, after a strict constant-temperature fermentation, rapid all-soluble, fast fertilizer effect, Stable and lasting. Yu Jun Bao EM highly active bacteria can quickly cultivate beneficial bacteria phase, and speed fat treasure, treasure with the use of fertilizer, fertilizer can effectively strengthen the effect.
