Rice field fish safety summer 5 measures

In summer, due to the low water content of paddy fields, high water temperatures, and the rapid increase in fish discharge, the water is easily contaminated and causes oxygen deprivation. A slight oversight will result in the mass death of fish. In order to ensure the safety of rice cultivation in summer, the following five measures must be taken:

One, often dredge fish ditch, fish slip. In summer, due to increased fish consumption, excessive bait and excrement, and fish activity, fish ditch and fish slip easily blocked, causing the ditch and slippery water level to decrease, affecting the fish. Growth and reproduction. This should be done once every 3-4 days to ensure that the fish ditch is 40 cm wide, 30 cm deep, and the fish slips 60-80 cm deep, and that the gutters are connected and the gutters are connected.

Second, keep the rice paddy fish water level. The depth of the water level in paddy fields is directly related to the speed of fish growth. If the water level is too shallow, it can easily cause sudden changes in water temperature, which can lead to the death of large numbers of fish. Therefore, the water level of rice in paddy fields is more than 10 cm higher than that of normal paddy fields, and new water is injected once every 2-3 days to ensure water quality. Fresh and cool.

Third, do "four fixed" feeding. Qualitative, that is, the forage material to be tender, fine material must be no mildew, manure to be fermented; two quantitative, that is, the amount of bait to eat on the same day as well; three timing, that is, 6-7 am, It is advisable to feed at 5-6 pm. Do not feed at noon; four positions, that is, the position of feeding is appropriate to choose to swim in the fish, because the deeper water level inside the fish allows the fish to concentrate on feeding, and also provides for the removal of residual baits and fish excrement. Convenience.

Fourth, take a shelter. In summer, in addition to maintaining a certain level of water in the paddy fields, it is best to shale a straw in a pergola above the fish slide. At the same time, aquatic plants such as duckweed can also be stocked in the fish to be used as a bait for fish and shade. The role of summer heat.

Fifth, reasonable fertilization, such as paddy fields in the summer really need fertilization, should adhere to the application of organic fertilizer, as little as possible or not applied inorganic fertilizer, and do a small number of times.

The definition of Finished Pharmaceutical Product can be found in § 4 (1) of the Medicines Law. It reads: "Finished drugs are drugs that are prepared in advance and sold in specific packaging to the consumer..." The drugs are mostly in the form of tablets, capsules, drops, liquids, ointments and suppositories. For Phytotherapy (healing with plants) numerous drugs are also available in pharmacies in which drugs or drug preparations are processed. One distinguishes between the drug preparations: the chopped drug to prepare a tea, the milled drug (= drug powder) and the dried extract for the manufacture of tablets, capsules and pills, tincture for the preparation of drops and the fluid extract for juices, salves and other ointments to name a few. A finished drug with a drug formulation is called an "herbal medicine" or phytopharmacon (plural: phytopharmaceuticals).
