First, sowing time and scope. From now until the end of July, vegetable soybeans can be sown in the province and the yield is high and the benefits are good. Sowing period: Before the July 20th in Huaibei area, the area south of the Huaihe River can be planted before the end of July.
Second, choose early varieties. The early maturing varieties of “New Liuqing†selected by the Anhui Academy of Agricultural Sciences, and Tezao 1, Hefeng 25, etc.
Third, cultivation techniques
1, early fertilizer. After emergence, combined with cultivator as early as possible to raise the seedlings, the flower buds will be topdressed with urea once again, and the foliar fertilizer will be applied once during the flowering stage.
2, increase the density. The sowing rate is generally 6 kg per mu, sowing sowing of 4 to 5 seeds per hole, and 20,000 basic shoots per mu.
3. Strengthen field management, pay attention to cultivating and weed control, properly control water before harvesting, and irrigate during drought in flowering stage.
4. Prevention and control of pests and diseases Damage to soybeans mainly includes aphids, leaf miners, red spiders, Spodoptera litura, and soybean meal. Aphids, leaf miners, and spider mites can be controlled by A. versicolor and Fructus lycii; Spodoptera litura and pods can be controlled by bt biocides and enemies, and once again after 10 days.
The diseases that damage soybeans mainly include viral diseases, rust, powdery mildew, downy mildew and purple spot. Viral disease is mainly transmitted by locusts. It is necessary to control and control maggots with 800 to 1000 times of viral emulsion, and then 7 days for prevention. Rust and powdery mildew can be treated with triadimefon or zeocin; downy mildew. Chlorothalon can be used to control.
5, timely harvesting, in the soybean meal from bottom to top gradually mature, select the full, still green soybean meal harvest. The harvest was repeated for multiple harvests and the final harvest was completed.
An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody (usually) or an antigen (sometimes). The molecule detected by the immunoassay is often referred to as an "analyte" and is in many cases a protein, although it may be other kinds of molecules, of different size and types, as long as the proper antibodies that have the adequate properties for the assay are developed. Analytes in biological liquids such as serum or urine are frequently measured using immunoassays for medical and research purposes.[1]
Immunoassays come in many different formats and variations. Immunoassays may be run in multiple steps with reagents being added and washed away or separated at different points in the assay. Multi-step assays are often called separation immunoassays or heterogeneous immunoassays. Some immunoassays can be carried out simply by mixing the reagents and sample and making a physical measurement. Such assays are called homogeneous immunoassays, or less frequently non-separation immunoassays.
The use of a calibrator is often employed in immunoassays. Calibrators are solutions that are known to contain the analyte in question, and the concentration of that analyte is generally known. Comparison of an assay's response to a real sample against the assay's response produced by the calibrators makes it possible to interpret the signal strength in terms of the presence or concentration of analyte in the sample.
