Pond cultivation conditioning water is the focus

I. Water quality analysis and culture In the aquaculture process, we generally perform simple water quality analysis on a regular basis, and qualified entities can establish their own laboratories. The pH value of water, the hardness of water, the content of ammonia and nitrogen in water body, the content of heavy metal ions such as mercury, lead, and copper in the water body all affect the breeding effect. In particular, most fish prefer to live in a neutral and alkaline environment. , Ammonia content in a small water environment. Second, aquaculture water management and regulation in the aquaculture production process, with a good source of water and good water quality, but also pay attention to the regulation of water, aquaculture water management and regulation is an important content, this problem can be summarized in the following three aspects . Water level adjustment In the aquaculture process, we need to timely adjust the water level according to different seasons and different growth stages of the fish. After the beginning of spring each year, the water level is lowered to raise the water temperature rapidly so that fish can be eaten as soon as possible. In the process of summer seedling cultivation, the summer flower cultivation before the “inch piece” should keep the depth of the pool water at about 50cm, and then gradually grow with the fish. Deepen the water level to increase the survival rate of seedlings and accelerate the growth rate. Before the advent of winter, deepen irrigation ponds to make the pool water reach the highest water level to maintain the higher water temperature of the bottom layer of the pond. In our Jianghuai area, the bottom water temperature of the 2 meters deep pond It can reach around 10°C, not only can increase the survival rate of fishes in winter, but also can carry out winter fishing at fishing grounds. Water temperature regulation Each fish has a certain temperature range, and water temperature detection is often performed and some adjustment methods are adopted to make the fish reach the optimal growth state. There are two ways to adjust the water temperature: first, artificially increase water adjustment, and timely add new water so that the temperature of the pond water reaches the optimal temperature of 28-30°C. This is particularly important in the open-air breeding of soft-shelled turtles; It is the adjustment of the ecological water temperature, and the proper cultivation of some aquatic plants. Water Quality Regulation Water quality regulation is an important aspect of water body management. It is summarized in the following four points: (1) Fresh water is added at appropriate times. Normally, new water is added every two weeks, each time about 30 centimeters of water is injected, and it is better to use aquaculture in a place where conditions permit. (2) Scientifically use oxygenation machinery. Generally, a 3kW aerator is installed for every 2,000 square feet, and the oxygen is turned on at a proper time. (3) Use quicklime to improve water quality. Each kilogram of lime water 25 kilograms of water after Quanchiposa, once a month. (4) Apply fertilizer timely. During the cultivation process, due to fish defecation, bait, residue and Other factors, the ammonia and nitrogen content of the pond are easily increased, and the fertilization amount is generally about 7 kg of dihydrogen phosphate per acre, so as to reduce the ammonia nitrogen concentration in the water and achieve fertilization. And regulate the dual effect of water quality. 3. When high-density culture of water and cultured species is carried out, the combination of different water layers and different varieties may be considered; when tropical fish (such as freshwater whitefish, tilapia) and cold water fish (such as rainbow trout) are cultured We must pay attention to the constraints of water temperature. Fourth, water and fish disease prevention and control of fish disease is a comprehensive factor, but the most closely related to water-related factors, we mainly pay attention to the following three points: (1), adhere to a daily morning and evening swimming pool, ground fish debris and die Fish to keep the pond clean. (2) Before the seedlings are planted, 250kg of quicklime per acre is used to thoroughly disinfect the ponds. (3) Regularly use 25g of lime or bleaching powder (containing 25% of available chlorine) per acre to disinfect the pool water and kill the parasite with 0.7g/m3 of trichlorfon. (4) The intensive culture of ponds is easy for eutrophication, so that the algae can multiply and form “bloom”, and 0.7 g/m3 of copper sulfate can be used for Quanchiposa. Fifth, the stress response of water and fish When the ambient temperature of fish life changes too much, it is prone to stress reaction, resulting in cold or frostbite. The temperature difference between the general fry release ponds should not exceed 2°C, and the temperature difference when the adult fish transfer to the pond should not exceed 5°C.

We offer full set Seed Processing Line solution. Whole seed processing line is from pre-cleaning, fine cleaning, destining, gravity separating, bean polishing, to seed coating, until seed weighing and packing.

 

The grain seed processing line is composed of several single machines. Base on different grain type and processing aim, we will suggest appropriate grain cleaning machines. These grain cleaning machines are collocated freely. Between each machines, there are Bucket Elevator , slope elevator or other conveying equipment to link up.

 

Seed processing line has following advantages:

 

Easy to setup, machines easy to move and can be placed freely.

Save labor, there are middle conveyors to transfer grain from one machine to another.

Effective and low cost, single machines compose a seed processing line improve the working performance. Low production cost makes it hot sale.

 

Above flexibility and convenience makes seed processing line makes it becoming hot sales item.

 

Seed processing line installation effect and introduction.

 

This seed processing line is composed of 5XZC-5DH seed cleaner & grader, 5XZ-5B Gravity Separator , DTY bucket elevator, 5BY-5B Seed Coating Machine, and DCS-50B Bagging Scale System.

 

Working flow: The seeds are fed into 5XZC-5DH seed cleaner & grader first. Seed cleaner & grader will remove the dust, light impurity, oversize and undersize impurity before seed flow into 5XZ-5B gravity separator. During seeds cleaned in gravity separator, the seeds are separated by density difference. The partially eaten seeds, immature seeds, insect damaged seed, sick seeds, moldy seeds are separated from good healthy seeds. Then seeds go on being lifted by Dty Bucket Elevator, falling into the 5BY-5B seed coating machine. During the seed coating procedure, the chemical, fertilizer or other protective liquidity will be coated to seeds' surface and improve seeds' germination rate. Finally seeds being transferred to Weighing Scale . Seeds will be weighted and packed to bags ready for sell.

One seed processing line includes several seed processing machines. It can be composed of different single machines freely. Base on client's particular cleaning aim, we will offer customized seed processing line. It is featured of simple operation, flexible and cost effectively.

 

Following is one simple seed processing line case show

 

This Seed Cleaning Line is 5 ton per hour capacity. And it consists of 5XZC-5DH seed cleaner & grader, Slope Elevator , 5XZ-5 gravity separator, and 5XQS-5 destoner.

 

Working flow:

 

Raw material is fed from seed cleaner & grader bucket elevator hopper. Then bucket elevator transfer raw material to air screen cleaner to remove the light impurity. The dust, straw, husk are removed here by air suction and collected by cyclone. Then raw material fall into sieve trunk. The sieve trunk has several layers. Each layer installed different hole size sieves. These sieves will grade raw material by size. So the oversize impurity, undersize impurity are removed. Seeds from seed cleaner outlet box are received by first slope elevator. This slope elevator transfer seeds to gravity separator. On the gravity table, the immature, eaten, sicken, moldy, shrink seeds are separated from good seeds. As the gravity separator will separated seeds to 3 parts: impurity, mixing seeds, good seeds. The mixing seeds are received by this first slope elevator too. It will take the mixing grain for reflow. The good seeds are being transferred by second slope elevator to the destoner. The destoner will separate the stones, heavy impurity out. Finally you get clean grain from the destoner good grain outlet box.
