How to control the grape overwintering

The management of the grape before winter is an important part of the annual management. Combined with the actual situation in the production process, the following measures for preventing cold and winter can be adopted:

Winter shears are winter shears before winter to reduce the evaporation of water from winter branches. Water should be irrigated once to maintain the water needs of the weak roots in winter. During the wintering period, it must be inspected once every half month. If the soil is found to be dry, it should be watered in time, but ice and snow should be avoided to avoid the water temperature being too low.

In order to ensure the healthy growth of the plants in the coming year, it is possible to apply some fermented organic fertilizers in combination with winter shears. Note that the amount of fertilizer used should not be too much, and the fertilizer should be replenished according to the standard of 100 grams per grape. Do not use the base fertilizer directly to contact the grape roots.

Cold insulation (1) bundled to cover the cold method. The trimmed grape vines are bundled into bundles, and then 1 or 2 layers of straw curtains or sacks are wrapped thereon. Then, 15 to 20 cm thick sawdust is covered, and then a layer of plastic film is covered, and the membrane is compacted with soil. . (2) Covering soil frozen ice method. Place the grape vines bundled and trimmed on the ground, cover the branches with straw bags, cover the soil 5-8 cm, and cover the grass with a layer of straw bags. When the temperature decreases from November to December, the water is continuously poured twice on the cover to make it freeze, thereby isolating the plant from the outside world and achieving the purpose of safe wintering. (3) Four layers of sand, membrane, leaf and straw to prevent cold. Firstly, the sand is covered with 20 cm thick on the branches, and a layer of mulch is covered on the sand. A layer of corn leaves of about 10 cm is placed on the mulch, and 60 cm of corn stalks are pressed on the leaves to protect the vines and the membrane. Leaf encryption, straw warming effect. The first three layers of coverage should be carried out in mid-to-late October. The latter layer should be carried out in the middle and late November after the freezing.

Automatic Nucleic Acid Extractor

Nucleic acid extraction instrument is an instrument that automatically completes the nucleic acid extraction of samples by applying the supporting nucleic acid extraction reagents. Widely used in disease control centers, clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial testing, food safety testing, animal husbandry and molecular biology research and other fields.
Using magnetic beads as the carrier, using the principle that magnetic beads adsorb nucleic acid under high salt and low pH value, and separate from nucleic acid under low salt and high pH value, and then move the magnetic beads or transfer the liquid to realize the entire extraction and purification process of nucleic acid. Due to the uniqueness of its principle, it can be designed into a variety of throughputs, which can be extracted from a single tube or 8-96 samples, and its operation is simple and fast. It only takes 30-45 minutes to extract 96 samples, which greatly improves the The experimental efficiency is low and the cost is low, so it can be used in different laboratories, and it is the mainstream instrument on the market.

Features of Magnetic Bead Nucleic Acid Extractor
1. Enables automated, high-throughput operations.
2. Simple and fast operation.
3. Safety and environmental protection.
4. High purity and high yield.
5. No pollution and stable results.
6. Low cost and easy to be widely used.
7. Different types of samples can be processed simultaneously.
