  • purpose of fertilizer and water

1, provide basic bait, improve the survival rate of seedlings, reduce the feed ratio, and improve the growth rate of shrimp.

2To promote the establishment of pond micro ecological balance, reduce water temperature fluctuations

3Sufficient oxygen, stable water environment

4, shading, avoid shrimp stress

5Purification of water quality. It is a positive cycle to absorb excessive amounts of ammonia, nitrogen, salts and other harmful substances before being ingested by shrimps.

Second, the factors affecting the fertilizer and water

1Temperature, weather. Spring stubble and autumn stubble, the water temperature and weather in the early stage are different, and the usage and dosage of fat water products are also different.

2, algae species, is natural selection or artificial intervention. In some areas, although the short-term impact is not significant, it has its drawbacks, such as the instability of the algae, which may occur repeatedly. These are obviously not the water colors we are pursuing, so it is cost-effective to supplement algae species appropriately and occupy space quickly.

3, the necessary nutrient elements for algae. In addition to nitrogen, phosphorus and potassium, calcium, magnesium and other trace elements are also necessary. Due to the early water is weak, mineral elements are insufficient, and shrimps are also consumed, so proper matching and supplementation will have better results.

4Residual toxins in water. Common problems, heavy metals and residual chlorine.

5, soil quality and water quality, some areas are naturalPHToo high or too low, organic matter more or less, total alkali total hard different. Algae growth also needs a suitable range, which can be detected and treated in advance according to the actual situation.

6Zooplankton. Rotifers and cladocerae can eat water in a short time. Direct sunlight to the end will cause shrimp stress, and moss may appear, making it difficult to feed water. Therefore, it is necessary to reduce or stop the material appropriately, and shade the light when necessary.

7Transparency of water.

As the shrimp grows,25To40Around the day, its ability to move gradually increased, constantly crawling led to the bottom of the mud, the water body gradually turbid, water transparency continued to decline to about.5-10cm.

At this stage, the bacterial-algal system in the water body changed dramatically, and the abundance of algae continued to decline.“fertilizer and water”On the one hand, we should try our best to maintain the abundance of algae, on the other hand, we should supplement a large number of beneficial bacteria, so as to control the increase of ammonia nitrogen and sub salt and inhibit the outbreak of harmful bacteria such as Vibrio.

Third, the common problems in the process of fertilizer and water

1, water is difficult to fertilizer, long-term adjustment is not fat. According to the influencing factors.

2, the water is too fat,phRising. Biological agents cooperate with carbon source to stabilize water, and more sets of fresh water

3, change is big, repeatedly pour algae, easy to get rid of fertilizer. Do a good job of water quality testing, culture of high-quality algae. What's missing, what's more, what's more. Before the weather changes, add fertilizer appropriately and take precautions in advance.

Four, Zhongren Aquatic Fertilizer Water Program

Idea: First use clear water to detoxify and protect water, then use detoxify and protect water to degrade residual toxins in water, then diatom flourishing, Zhongren enzyme fertilizer,EMJin Lu, super spores, super algae species, calcium and magnesium quick supplement, etc. are better to be used together according to water quality.

1Pre-stage fertilizer and water scheme

Diatom Wang1catty/Shed+Quick-acting fertilizer essence1catty/Shed+Bacteria Cube Fermentation Liquid10catty/Shed.7Day/Second, it is used when the water color is too clear in the early stage.

Product advantages:Diatom Wang,8:1:1Scientific ratio, special addition of diatom nutrients, rapid cultivation of diatoms

Bacteria Cube,EMBacterial expansion culture type, good activity, high content, fermentation per kilogram200Jin of fermentation liquid

2, middle and late stage fertilizer and water scheme

Diatom Wang2catty/Shed+Calcium and Magnesium Quick Supplement1catty/Shed+super spore3Two/Shed+Bacteria Cube Fermentation Liquid10catty/Shed.3Day/Times, stable water and fertilizer

Product advantages:super spore, hundreds of billions of spores, ultra-high content

Calcium and Magnesium Quick Supplement, rich in calcium magnesium phosphorus and other active trace elements, can improve the total hard total alkalinity of water body, help to maintain water fertility

5, thinking.This year, there is a new pattern of carbon source-only bacteria cultivation and biological flocs in the market. Personally, algae has been studied thoroughly, bacteria, less conclusive, beneficial and harmful may be relative. Therefore, based on the existing actual conditions, it is better not to go to extremes and to give consideration to both algae and bacteria.
