The pollution-free cultivation of vegetables is an important measure to ensure the quality and safety of vegetables. It can effectively reduce the harmful residues of vegetable products, increase the efficiency of nutrient utilization in vegetable fields, reduce the environmental pollution of vegetable fields, and has very important significance in improving the quality of life of the people, improving the international competitiveness of vegetables in China, and expanding the export of vegetables. The pollution-free cultivation of vegetables through ecological cultivation and physical control techniques, reduce medication, and the rational choice of the application of high-efficiency and low-toxicity pesticides, thus controlling the pesticide residue contamination. The first is to promote ecological cultivation techniques, to maximize the conditions for the growth and development of suitable vegetable crops, to develop pests and diseases, to prevent or minimize the occurrence of pests and diseases, so as to achieve the purpose of no drugs or less use of drugs; second is to adopt barriers, trapping Physical treatment measures such as high-temperature sterilization, control of pests and diseases, and reduction of medication; third, rational selection and application of highly effective and low-toxicity pesticides. Increase production and efficiency: Applying this technology, the average yield per unit of vegetables is 3,000 kg/mu or more, the new production value is 20%, the input of chemical pesticides in the production process is reduced by 50% from the current level, and the input of chemical fertilizers is reduced by more than 30%. Technical points: According to the current situation of vegetable residues, it mainly controls pesticide residues and nitrate pollution. 1. Pesticide Residue Control Technology (1) Control technology of pesticide residues in vegetables: 1 Insect pest control. Insect net barrier, yellow traps and reasonable choice of application of high-efficiency low-toxic pesticides. 2 disease prevention and control. Facilities control humidity and disease prevention [including cover-type drop-mist function film, under-membrane underdrain (drip irrigation)], use of disease-resistant varieties, peat nutrition nurturing strong seedlings, rain shelter cultivation, summer high temperature stuffy shed and reasonable choice of application efficiency Low-toxic pesticides. (2) Control technology of pesticide residues in horticultural products in open field: 1 Insect pest control. Frequency vibration type insecticidal lamp and reasonable choice of application of high efficiency and low toxicity pesticides. 2 disease prevention and control. Deep ditch sorghum, drip irrigation, mulching film, disease resistant varieties, peat nutrition nurturing strong seedlings, bagging cultivation and reasonable choice of the application of high efficiency and low toxicity pesticides. 2. Vegetable nitrate pollution control technology Including nitrogen fertilization, balanced fertilization, rational application of organic fertilizer, reuse of basal fertilizer, light dressing topdressing, the implementation of nitrogen fertilizer safety intervals to control nitrate pollution in vegetable products. Appropriate area: vegetable pollution-free cultivation technology applies to all vegetable production areas in the country.
Syringes are one of the most common instruments that use a system of Luer fittings, which are attached to a female needle that either screws into it or is screwed on top. There are two types of connection types: locking and sliding.
Luer lock syringes are more secure, the needle is inserted into the Syringe and twisted to form a locking connection; ensuring no fluid leakage and preventing accidental needle removal. Luer slip syringes are more convenient to use and require a simple push of the needle into the syringe and ready to go
