First, fertilizing the land
It is necessary to apply enough base fertilizer to cultivate wintering cucumbers. The base fertilizer should be mainly composed of decomposed straw compost, cattle and horse manure, chicken manure, pig manure and manure (the manure should be applied before the film is applied), and when the manure and manure are applied, the amount of minced fresh can be mixed. Straw, fully decomposed wheat bran, rice husk and discarded edible fungus culture medium. Generally, the farmer's fertilizer is 3000-5000 kg, 100 kg of superphosphate or 30-50 kg of diammonium phosphate or 40-50 kg of biological fertilizer or 200 kg of cake fertilizer. When the bottom fertilizer is used for a long time, it can be applied at 2/3 or 1/3. After the ground is applied, turn it over 2 times, then ditch according to the line spacing, apply the remaining fertilizer into the ditch, mix well with the soil, and then pour the water in the ditch to make the bottom. Overwintering cucumber cultivation generally takes large and small ridges, with a small row spacing of 80 cm, a large row spacing of 100 cm, and a planting of 3,300 to 3,500 plants per mu.
Three points of wintering cucumber cultivation technology
Second, colonization
1. Planting seedlings should be carried out on sunny days. According to the large, medium and small grades, the seedlings are transported to the side of the planting ridge. From the perspective of the whole greenhouse, the seedlings should be placed at the east and west ends of the greenhouse and the greenhouse should be placed in the middle of the greenhouse. From a line of view, the seedlings are in front, the seedlings are in the back, and the general seedlings are in the middle, which is beneficial to the subsequent growth. Because the light in the greenhouse is strong and weak, the seedlings and seedlings should be mastered before and after the seedlings, so that the seedlings in different parts get basically similar light. When planting, the planting distance can be opened according to the plant spacing, and the seedlings can be planted in the hole; or a deep ditch can be opened on the planting ridge, and the seedlings can be placed in the ditch to be fixed in the ditch. Watering in the cave or in the ditch, sealing the pit (ditch) after the water seeps. Note that the seedlings should not be planted deep. After the soil is sealed, the nursery and the ridge surface are flat. Note that the marriage interface cannot be buried in the soil.
2, covering the mulch film in the past people used to mulch after planting cucumber, or cover the mulch immediately after planting. This is actually not conducive to the deep rooting of the grafted roots, which reduces the ability of the plants to resist cold and cold. Because the ground temperature is higher at the time of planting, it is not necessary to cover the film. After the planting, it should be based on repeated strokes to promote the deep rooting of the roots, and cover the mulch film about 15 days after planting.
Third, hanging vine
When cultivating wintering cucumbers, in order to promote development and maintain the vitality of the roots, most of them are methods of not allowing them to grow naturally. Overwintering cucumbers generally grow to 40 to 50 knots, and the greenhouse is limited in height.
In order to facilitate the vine, the nylon thread, the cloth hang, or the nylon mesh bracket are generally used, which can greatly reduce the shading of the frame. When hanging nylon or nylon mesh, try not to connect directly to the greenhouse arch, preferably stand alone. The nylon thread for hanging should be left in the upper part to be used for the vine. When hanging the vines, the operation should be light, do not sink too much at a time, and do not damage the blades. To make the blades evenly distributed in space, do not block each other. At the same time, it is necessary to remove the lower yellow leaves, side branches, tendrils, male flowers, deformed melons and diseased melons. Leaf picking is not a necessary measure. Generally, the leaves that are better in growth and more intact should not be easily removed. Generally, the leaves should not exceed 2 to 3 pieces, and try to keep about 20 pieces of functional leaves per plant.

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.
