Taro planting technology: watering instructions for steamed bread in different periods
For the cultivation of taro, we must know that the growth and development of taro mainly include the taro seedling stage, the tick hair stage, the taro crust stage, and the taro dormancy period, and the watering requirements are different for each period.
1. Taro seedling stage: 20~25 days after sowing the seedlings from the broken membrane, when the top buds of the hoe are exposed to the ground, it is necessary to break the membrane and induce the seedlings in time to prevent high temperature baking; the soil around the membrane is tightly pressed to prevent water dispersion and weeds. Growing. The soil moisture content of the taro seed during the germination period should not be too high, otherwise it will affect the germination and lead to rotten species. During the seedling stage of taro, depending on the lyrics and weather conditions, you can pour small water or not, as long as the soil is kept moist.
2, hair growth period: the hair growth period is the key period for Shantou to seize high yield, to supplement a certain quick-acting nitrogen fertilizer. Generally, 10 to 15 kg of urea is applied per acre with water. At this stage, the steamed bread should have enough water, but it should be prevented from flooding and pay attention to loosening the soil in time. When loosening the soil, it is best to walk behind the ditch to prevent soiling and improve soil permeability.
3, gimmick period: in order to ensure the growth of hoe and the expansion of the larvae, at this stage to maintain adequate nutrient supply. Generally, 30 kg of ammonium bicarbonate and 40 kg of potassium dihydrogen phosphate are applied with water twice acre. During the hot period of the steamed bread, the steamed bread grows vigorously and the bulbs expand rapidly. The irrigation should be carried out once every 5 to 7 days depending on the sensation and weather conditions.
Cutting buds: The taro leaves consume a lot of nutrients, which is not conducive to the transportation of nutrients to the bulbs, affecting the expansion of the seeds. Covering cultivation does not require soil cultivation, but it is necessary to quickly cut off the cotyledon buds before the cotyledon buds 2 leaves, thereby reducing the loss of nutrients and improving the yield and quality of steamed bread.
4. Dormancy period of taro: In the later stage of taro growth, the water requirement is gradually reduced, especially before harvesting, to keep the soil slightly dry. Keep the plot, the soil moisture should not be too low, convenient for storage.
Magnetic Bead Nucleic Acid Extraction Reagent
The magnetic bead method nucleic acid extraction kit is a high-tech product that combines biological science and nanomaterial science. It is a major breakthrough in my country's nucleic acid extraction and purification technology. . Magnetic bead method for nucleic acid extraction has incomparable advantages over traditional DNA extraction methods, which are mainly reflected in: 1. It can realize automatic and large-scale operation. At present, there are 96-well nucleic acid automatic extraction instruments, and the extraction time of one sample can be realized. The processing of 96 samples complies with the high-throughput operation requirements of biology, enabling rapid and timely response to infectious disease outbreaks, which makes traditional methods unmatched; â‘¡ The operation is simple and time-consuming, and the entire extraction process has only four steps , most of them can be completed within 36-40 minutes; â‘¢ Safe and non-toxic, no toxic reagents such as benzene and chloroform in traditional methods are used, and the damage to experimental operators is minimized, which fully conforms to modern environmental protection concepts; â‘£ Magnetic beads and nucleic acids The specific binding of the extracted nucleic acid results in high purity and high concentration of the extracted nucleic acid. According to the same principle as the silica membrane spin column, the superparamagnetic silica nano-magnetic beads are prepared after the surface of the superparamagnetic nanoparticles is modified and modified by nanotechnology. The magnetic beads can specifically recognize and efficiently bind to nucleic acid molecules on a microscopic interface. Using the superparamagnetic properties of silica-coated nanomagnetic microspheres, under the action of Chaotropic salts (guanidine hydrochloride, guanidine isothiocyanate, etc.) and an external magnetic field, samples from blood, animal tissues, food, pathogenic microorganisms, etc. The isolated DNA and RNA can be used in clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial testing, food safety testing, molecular biology research and other fields. Magnetic bead nucleic acid extraction can generally be divided into four steps: lysis-binding-washing-elution. Genetic testing will surely become a new symbol of the development of the biological industry. The emergence of high-throughput, automated nucleic acid extraction methods will reduce the labor cost of genetic testing, make large-scale testing a reality, and make it possible for genetic testing to reach ordinary people.
