Main points of management of wheat peanuts
1. Sowing at the right time. The wheat-covered peanuts have a large planting area in the central and southern plains of our province. The best sowing date is from May 20 to 25, and the planting is completed at the latest at the end of May. Generally medium fertility plots, 10,000 acres of sowing, two seeds per hole, sowing depth of 3 to 5 cm, sowing water after sowing.
2. Cultivate and remove mites. Cultivating and removing mites can eliminate the breeding grounds of germs and pests, and can also increase the ground temperature, promote the development of roots, and facilitate the lowering of fruit needles, thereby increasing the fruit setting rate of peanuts and increasing the yield. Two days after the watering of the peanuts, the wheat stubble is removed in time. After the cultivation, the weeds are removed and the weeds are removed. The peanuts are usually ploughed 2 to 3 times before the peanuts are closed.
3. Chasing seedlings. The former glutinous wheat consumes a large amount of soil nutrients throughout the growing season. After the wheat harvest, most of the plots have insufficient fertility. Therefore, it is necessary to timely apply the seedling fertilizer to the wheat straw to promote the rapid growth of the plant. The topdressing fertilizer should be based on quick-acting nitrogen fertilizer, and 20 kg of urea should be applied per acre combined with watering. After 3 to 5 days of wheat harvesting, fertilize and water in time.
4. Control pests. After the wheat harvest, there is a constant high temperature, which is prone to red spiders, second-generation cotton bollworms, and sticky insects. Such pests ingest and bite peanut leaves, affecting the normal growth of plants, and should be prevented early. It can be controlled by spraying 2.5% of cyhalothrin emulsion 1000-2000 times to control the seedling pests and lay a foundation for high yield.
There are mainly the following parts: 1. Sampling swab with disposable sterile plastic rod/rayon head 2. Sterile sampling tube containing 3ml of virus maintenance solution (gentamicin and amphotericin B are selected to better inhibit the fungus in the sample. Avoid the human sensitization reaction that may be caused by penicillin in the traditional sampling solution.) In addition, there are additional parts such as a tongue depressor, a biosafety bag, etc. Intended to use 1. It is used for monitoring and sampling of infectious pathogenic microorganisms by disease control departments and clinical departments. It is suitable for sampling of influenza virus (common influenza, highly pathogenic avian influenza, H1N1 influenza virus, etc.), hand, foot and mouth virus and other types of viruses. It is also used for sampling of Mycoplasma, Chlamydia, Ureaplasma, etc. 2. It is used to transport nasopharyngeal swab samples or tissue samples from specific parts from the sampling site to the testing laboratory for PCR extraction and testing. 3. It is used to preserve nasopharyngeal swab samples or tissue samples from specific parts for necessary cell culture. The virus sampling tubes are loaded with infectious substances, and some are even highly pathogenic substances. Therefore, the requirements for packaging containers are very strict, and three requirements must be met at the same time: 1. The safety of transportation. Ensure that the sample does not leak during transportation. Sampling tubes that comply with WHO regulations and biosafety regulations. 2. The security of preservation. Ensure that the sample does not leak during storage. Sampling tubes that comply with WHO regulations and biosafety regulations. 3. The validity of the sample. Make sure that the sampling tube itself will not have a toxic effect on the sample.
