With the improvement of people's living standards, people's health awareness and environmental awareness have been further enhanced. Unpolluted vegetables have become an urgent need for people. Non-environmental pollution vegetables refer to vegetables whose residual levels of harmful substances in vegetable products meet the national health and safety standards. First, pesticide residues do not exceed the standard. Non-polluted vegetables do not contain banned high-toxicity, high-residue pesticides. Other pesticide residues do not exceed the national maximum. Permissible limit; Second, the nitrate and nitrite content does not exceed the standard; Third, the "three wastes", heavy metals and pathogenic microorganisms pollution does not exceed the standard. Among them, the problem of heavy metal, nitrate and nitrite content is closely related to the rational use of fertilizers. There are many factors that restrict the production of pollution-free vegetables, and how to correctly select and apply fertilizers is one of the key measures for the production of pollution-free vegetables.
First, the choice of fertilizer
The types and types of fertilizers that do not have adverse effects on the environment and the nutrition and quality of vegetables should be selected. The types and types of fertilizers that can be applied in the production of pollution-free vegetables include the following:
(1) Organic manure includes farmyard manure and commodity organic manure, and manure manure includes compost, mud manure, cake manure, manure manure, biogas manure, green manure, and crop straw. The compost should be in accordance with NY/T 394-2000 "High Temperature Composting Hygienic Standards." Commodity organic fertilizers should meet NY/T5018 "Standards for Permissible Content of Contaminant in Organic Fertilizers".
(b) Microbial fertilizers include humic acid fertilizers, rhizobia fertilizers, potassium bacterial fertilizers, phosphorus bacterial fertilizers, and composite microbial fertilizers. The number of viable microbial organisms must meet the requirements of 4.1 in the “Microbial Fertilizer†(NY227), and the hygienic indicators must meet the requirements of the “Integrated Products in Harm Index†of NY227.
(3) Inorganic mineral fertilizers include inorganic nitrogen fertilizers, mineral potassium fertilizers, and mineral phosphate fertilizers. Inorganic nitrogen fertilizer should be applied to the application of iron nitrogen fertilizer or urea; phosphorus, potassium fertilizer should be in line with NY/T394-2000 health standards, in which phosphate fertilizer promotes the application of calcined phosphate, impurity control indicators are: each containing 1% of phosphorus pentoxide, As ≤ 0.004%, Cd ≤ 0.01%, Pb ≤ 0.002%; Potash promote the application of potassium sulfate, impurity control indicators are: each containing 1% kalium oxide, As ≤ 0.004%, Cl ≤ 3%, sulfuric acid ≤ 0.5%.
(D) Trace elements in fertilizers such as calcium, magnesium, copper, iron, boron, zinc, molybdenum, manganese, etc.
Antimalarial:
Antimalarial medications, also known as antimalarials, are designed to prevent or cure malaria. Such drugs may be used for some or all of the following:
Treatment of malaria in individuals with suspected or confirmed infection
Prevention of infection in individuals visiting a malaria-endemic region who have no immunity (Malaria prophylaxis)
Routine intermittent treatment of certain groups in endemic regions (Intermittent preventive therapy)
Some antimalarial agents, particularly chloroquine and hydroxychloroquine, are also used in the treatment of rheumatoid arthritis and lupus-associated arthritis.
Current practice in treating cases of malaria is based on the concept of combination therapy, since this offers several advantages, including reduced risk of treatment failure, reduced risk of developing resistance, enhanced convenience, and reduced side-effects. Prompt parasitological confirmation by microscopy, or alternatively by rapid diagnostic tests, is recommended in all patients suspected of malaria before treatment is started. Treatment solely on the basis of clinical suspicion should only be considered when a parasitological diagnosis is not accessible.
Antiparasitic:
Antiparasitics are a class of medications which are indicated for the treatment of parasitic diseases, such as those caused by helminths,amoeba, ectoparasites, parasitic fungi, and protozoa, among others. Antiparasitics target the parasitic agents of the infections by destroying them or inhibiting their growth;[4] they are usually effective against a limited number of parasites within a particular class. Antiparasitics are one of the antimicrobial drugs which include antibiotics that target bacteria, and antifungals that target fungi. They may be administered orally, intravenously or topically.
Broad-spectrum antiparasitics, analogous to broad-spectrum antibiotics for bacteria, are Antiparasitic Drugs with efficacy in treating a wide range of parasitic infections caused by parasites from different classes.
