What if there is moss in the shrimp field? How can it be cleaned? Can it be killed with salt?

Salvage: if it is cloth-shaped moss or lump-shaped moss, salvage method can be used. Sunbathing: suitable for ponds without shrimp seedlings and adult shrimps, dry water and sun treatment. Deepen the water level: suitable for ponds with more adult shrimp and young shrimps, deepening the water level helps to shade and eliminate moss. Spray: use drugs to remove moss for treatment. Fertilization: choosing a reasonable fertilizer can also kill the moss. Water quality: after the treatment of moss, the water quality should be adjusted to facilitate the growth of shrimp.

A large amount of moss will appear in the shrimp field accidentally, which will cause great trouble to the farmers. Many farmers ask whether salt can be used to kill the moss. In fact, salt does not have much effect in killing the moss. So how can we effectively remove the moss from the shrimp field? Here are 6 ways to remove moss from shrimp fields. I hope they can help you.

First, salvage moss

Generally common moss are sunk to the bottom, attached to aquatic plants, floating on the water surface, clustered and lumpy, and the most difficult to deal with are scattered in the water. Cloth-shaped moss and lump-shaped moss are relatively easy to salvage, and slippery moss is the worst. Prepare mesh-tight tools when salvaging slippery moss, and try to slow down when fishing up from the bottom of the pool. If there are aquatic plants have been covered with moss must be salvaged, even if a small amount of aquatic plants together can not be let go.

2. Drying the fields

This method is suitable for killing moss in the pond without shrimp seedlings or adult shrimp, in the whole winter or early spring, sunny days with little rain, dry climate, drying the fields to kill moss, it is the most simple, applicable and economical. Whether it is the old pond or the new pond, the water needs to be discharged cleanly, and if the pond with deeper silt needs to dig the filter ditch. It must be noted that once stagnant water is found, it should be discharged in time. After exposure to the bottom of the pond and permafrost treatment, most of the moss can be disposed of. When the moss is low in the sun, if you find a lump of moss, be sure to turn it over after drying, and then tow it away or burn it after drying.

Third, deepen the water level

It is suitable for use in ponds with more adult shrimps and existing young shrimps. In early spring or winter, it can deepen the water level, help to shade the light and eliminate moss. When the water level deepens to more than 1m, the transparency of the water will not reach more than 70cm, and there will be no light at the bottom, so the moss growing at the bottom cannot carry out photosynthetic crops, and over time, the moss at the bottom and the moss in the deep water layer that cannot carry out photosynthesis will not be able to survive, thus killing the moss.

IV. Spraying drugs

Qingmajing can be used to kill moss, the drug is a biological enzyme preparation, will not hurt fish, shrimp and crabs, will not hurt grass algae seedlings, no side effects, but also can directly and effectively kill all kinds of moss.

Whole pond moss: if the whole pond is covered with moss, we should first catch part of the moss artificially to form a return ditch in the pond, which can improve the crayfish's living space, and then kill the moss.

Surface moss: if there is moss on the upper layer of the pond surface, it can be sprayed with moss directly. In about 3 days, the moss will turn yellow. At this time, the moss will turn yellow. At this time, the moss will be fertilized and fermented with the giant EM bacteria.

The treatment of the moss at the bottom of the moss: the moss net 1 bag is mixed with about 2 kg of water, sprayed on the dry sand, phosphate fertilizer, and large packaging biological bottom, and then mixed evenly, covered with a plastic bag, wait for about 2 hours, and dry it. Scatter it on the moss at the bottom, as long as there is moss, you don't need to sprinkle it, and calculate the usage according to the specific pond area. In about 2 days, the moss will turn yellow and wither. At this time, it will begin to fertilize and cooperate with the fermented giant EM bacteria. When the moss is about to die out, it will be detoxified and changed.

5. Fertilization

It is very important to choose the right kind of fertilizer in winter, first put the right amount of fermented organic fertilizer crop base fertilizer, and then spray the whole pool with high-quality amino acid fertilizer together with organic biological fertilizer, about once in half a month, you can control the transparency around 50cm, which can not only provide high-quality natural bait for crayfish, but also kill moss. The effect of this method is better when the water depth reaches more than 70cm.

VI. Conditioning of water quality

After a series of measures mentioned above, the water quality has changed greatly, such as muddy blackening and so on. When the water is turbid, high content sodium humate products combined with chemical flocculant can be used to deal with it. In other cases, organic acids and sodium thiosulfate are used for detoxification. If the water temperature is higher than 15 ℃, some other follow-up problems can be solved by using the original species of Bacillus giganticus and lactic acid bacteria.
