The grower Lao Liu planted 40 acres of potatoes, and the annual output was more than enough. Lao Liu was in a low mood. Every year, if you don’t grow up every year, it’s definitely a problem! One day, just met with agricultural experts who are discussing with you how to do a good job in the field management of potatoes, to promote the potato to become sick, to use less medicine, and to achieve high yield. Many people came to watch, Lao Liu also couldn’t help himself, so he came over to hear what the experts said!
After five passes and six will, the high yield of potatoes must first pass these 7 levels!
The first level: selection of ground, the choice of deep soil layer and loose soil before planting, and deep soil (deep tillage) and rolling (honing, suppression).
The second level: selection of seeds: the seed selection is good, the potato to take a big step forward to high yield, we must choose the seeds with strong disease resistance.
The third level: use fertilizer, crops should be high-yield, relying on fat to be the home, nutrition to the foot, the potato can force you to grow long! According to the physiological requirements of potato for fertilizer, a large amount of elements are blended according to the ratio of pure nitrogen, phosphorus and potassium 2:1:4, and moderate elements such as zinc, boron, magnesium, calcium and sulfur are applied, and organic organisms are applied. Bacterial fertilizer. Under the action of microorganisms, it can not only release nutrients for plant absorption, but also promote soil looseness and fertility, increase gas permeability and drainage, and achieve a yield of more than 5 tons. The macro- and medium-quantity compound fertilizer should not be less than 150 kg per mu. The organic biological fertilizer should not be less than 500 kg.
Fourth pass: density off
The implementation of a ridge and double row cultivation, the ridge width is 120 cm, the ridge height is 25-30 cm, the ridge is two rows wide by 25 cm, the plant spacing is 25 cm, and the triangle is placed in a variety of 4444 plants.
Fifth level: grading off
Taking the early-maturing type of Dutch potato as an example, the head bud eye potato block and the chest bud eye potato block and the tail bud eye potato block are basically divided into three types after cultivation: the head bud eye potato grows fast, the potato block is large, and the chest bud eye is secondary. It is useless after the tail bud eye potato block. To capture high yield, when cultivating, divide the bud eye of each potato block separately, and divide the first bud potato block and the second bud potato block separately. When the seed germination eyes are all facing upwards, each nest has two 0.8-1.5 kg. The big potato on the right and left, when the potato bud eyes are down, four medium-sized potatoes of 0.4-0.7 kg are formed, and the depth is 10 cm.
The sixth level: innovation
Innovative cultivation, after the ridge is raised, open a 15 cm flat ditch in the center, apply the base fertilizer at the center of the ditch, place the potato block at both ends of the ditch, and spread the drip irrigation belt at the center. Then the straw is 10 cm thick and parallel with the ridge surface. Cover the mulch.
The seventh level: management off
During the whole process of potato growth, the seed potatoes were removed from the seedlings in time, and the seedlings were kept in a long-term manner. The 15-day field pests and diseases were inductively controlled, the early application of the base fertilizer, the skillful application of the seedling fertilizer, and the high yield management of the potato fertilizer. The model can completely complete the cultivation intention of high yield and high efficiency.
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.
