The main differences between powder,premixed agent, granule are as follows:
Veterinary Soluble Powder: means a dry powder preparation made of one or more drugs by grinding and evenly mixing, with or without dressing.
Premix: refers to one or more drugs, and a suitable substrate evenly mixed to make a powder or granular preparation.
As a dosage form of feed drug additive, it is specially used for mixed feeding.
Powder powder, that is, powder, and premixed agent, the main differences of granules are as follows:
1.the production method is different
1.powder: medicine or with appropriate auxiliary materials by grinding, evenly mixed dry powder preparation.
2.Veterianary premix: powder or granular preparation made by evenly mixing the drug with an appropriate substrate.
3.granules: raw materials and appropriate excipients mixed into a certain particle size of dry granular preparation.
2.different characteristics
1. Dispersing agent: compared with other solid dosage forms, dispersing agent is easy to disperse, dissolves quickly, absorbs quickly and takes effect quickly; The preparation process is simple, the dosage is easy to control, and it is easy for infants to take.
2.Premix for animal: Premix used in the matrix including carrier, diluent, etc. The substrate should be stable, with good fluidity, and easy to mix with drugs and feed.
3. Granule: the dispersion, adhesion, agglomeration and hygroscopicity of granule are lower than that of granule; The separation of various components in granule is avoided because of the adhesive used to make granule after mixing. Convenient storage and transportation; Particles can change their function by coating.

1. Net catching method: Before the rice is harvested, it is set in the drainage port of the rice paddy field with a triangulation, and then the field water is discharged. The muddy water is captured when it falls down with water. This method is difficult to catch once and can be re-irrigated and captured repeatedly.
2. Drainage field water capture method: after harvesting in late autumn rice, dredge the fish in the middle of the field and drain the fish, drain the field water, make the muddy water flow into the ditch and slip through the water, use the copying net to capture, and then use Nets made of iron wire are even picked up together with silt to remove silt and leave mud. When the weather is hot, it can be done in the morning or in the evening. The part of mud left over in the soil of Tanaka can be left in winter in the middle of the Yangtze River, and it will be raised again in the following year. In areas north of the Yangtze River, it is necessary to try to catch it, and it can be used for ploughing, water digging or plowing for capture.
3. Scented bait trapping method: both before and after rice harvest. In the evening on sunny days, the Tianshui will slowly dry out. After the evening of the next day, slowly pour the water into the pit and let the loach focus on the fish pit (sleak), and then put the pre-fermented baits into the Muzzle sacks and sink into the fish pit to trap. This method is better during the period from May to July. It should be under the bag in the evening if it is after August, and it should be taken out before sunrise the next day. Stopping the food the day before the bag can increase the fishing effect. If there is no sack, you can use the old straw mat to grow 60 centimeters wide and 30 centimeters wide. Mix the sauteed rice bran and silkworm cocoon flour with the clay to make the dough into the mat. Put some branches in the middle and roll it up. Tighten up so that the mat bulges slightly. Then put Tanaka, the upper part of the water surface slightly exposed, and then put some weeds, etc., muddy will go to the straw mat food.
4. Cage catching method: It is to use a cage or cage to catch.
5. Drug-fighting method: The commonly used drug is tea aphid (also known as tea withered, tea cake, is the residue after oil extraction, storage time does not exceed 2 years), the amount of rice fields per 667 square meters of 5 to 6 kg. The drug is baked for 3 to 5 minutes and then taken out. The powder is soaked in hot water and soaked in water (hands folded and loosened). It can be used after 3 to 5 hours.
Put the water in the paddy field down to about 3 cm, and then set up fish nests in the four corners of the field. The nests of fish are piled up with silt, and the nests are stacked in a ramp shape, gradually rising from low to high 3 to 10 cm above the water surface. The size of the fish nest depends on how much the loach is, and the size of the nest is generally the size of a foot basin, with an area of ​​0.5 to 1 square meter. Fish nests should also be set up in the center of large paddy fields.
Application should be carried out in the evening. With the exception of the nests of fish nests, pesticides should be sprayed evenly throughout the rice fields. It is not advisable to move in the middle of the field after applying pesticides before catching. Muddy will generally drill into muddy fish nests under the influence of tea pots.
On the morning of the second day after the application, the fish nests are surrounded by mud and the water in the fish nest circle is drained to dig nests and catch the mud. Loach that meets the specifications of the product can be directly marketed, and those that have not reached the product specifications continue to stay in the field. If it is necessary to inject fresh water with a depth of about 5 cm in the farm in Rutian, it can be moved to his temporary place where conditions permit, and after about 7 days, the Chinese herbs in the field will disappear, and then they will be fed into the paddy fields. This method is simple and easy, fishing speed, low cost, high efficiency, and no pollution (to control the dosage). In the water temperature of 10 ~ 25 °C, the capture rate of up to 90%, and can catch large stay small, a balanced listing. However, the following matters should be noted during operation. The first is the use of tea brewing liquid preparation to be used with the match; followed by the amount must be strictly controlled, the application must be evenly sprayed all over the field (except the fish nest); In addition the nest of fish nest must be higher than the water, and can not be There are grass and mud piles that rise above the surface. The catching time of this method is best after the rice is harvested, and there is no fish-collecting pit or slipping in the rice field; if there is a fish-collecting pit or slip in the rice paddy, the pesticide may not be applied in the fish-collecting pit or slip, and the pit, Walk around to prevent muddy entry.
Paddy field muddy fishing method
The loach grown in paddy fields is generally harvested when the rice is about to be cooked, and it can also be harvested after rice is harvested. There are generally the following five kinds of fishing methods.
