Nowadays, there are more and more people planting fruit trees. If you want to plant fruit trees, the most important thing is to choose a good place to build an orchard. Generally speaking, to build an orchard, in the choice of the site, it is necessary to choose a flat land with good ecological conditions, environmental quality and sustainable production capacity. But in fact, there are not so many good flats to choose from. Many farmers will choose to build orchards on the mountains. What are the pros and cons?
1, good light
The mountain has a certain degree of slope. If the orchard is built in this place, the illumination will be better, and the influence between them is not very big. This is a bit like the stepped seat we usually go to the theater. of. In addition, the temperature difference between this place and the evening will be relatively larger. Everyone knows that the fruits grown in such a large temperature difference are generally delicious.
In addition to good lighting, the ventilation in this place is generally quite good, the fruit grows not only delicious, but also very beautiful.
2, good drainage
If an orchard is built on the mountain, the drainage will be better. For example, if there is continuous heavy rain, there will be no water accumulation in the soil. If there is water, most of it will flow away, so the oxygen content of the soil will be higher. It is conducive to the growth of the roots of fruit trees.
3, suitable for different varieties
If you build an orchard in the mountains, there will be some differences in altitude. In this case, you can plant several varieties, which is quite good, so that the fruit can be more competitive.
4, the soil layer is not the same
Of course, if you build an orchard on a mountain, there are some shortcomings. For example, in some places, the soil layer is thicker, and in some places, the soil layer is thinner. Where the soil layer is thin, it may be even worse in terms of water retention and fertilizer retention, and fruit growth may be affected.
In addition, there are some complicatedities in the terrain of this place. Relatively speaking, the transformation has some troubles, and the traffic may not be very convenient.
The above is an analysis of the advantages and disadvantages of mountainous orchards. In general, the advantages outweigh the disadvantages and can be considered. After all, there are not so many good flats that can be chosen for us.

Nucleic Acid (DNA/RNA) Extraction Kit
1. Introduction
The total viral nucleic acid extraction kit is suitable for extracting total viral nucleic acid from serum, plasma, tissue homogenate and other samples. The kit is based on silica column purification technology, which eliminates the need for toxic phenol-chloroform extraction and time-consuming alcohol precipitation. This product has successfully extracted nucleic acids from hepatitis B A/C, hepatitis C, and norovirus standard. The obtained DNA/RNA can be directly used in a series of downstream experiments such as PCR, RT-PCR, and LAMP.
Notice:
1. The carrier RNA solid must be dissolved in Nuclease Free Water to 1µg/µl before use, and vortex to dissolve. Store in aliquots at -70°C. If you need to store it at -20℃ for a long time, please repackage it according to the number of times of use.
2. Dissolve Proteinase K (20mg/ml): Add Proteinase Dissolve Buffer to dissolve Proteinase K to a final concentration of 20mg/ml. Proteinase K dry powder can be stored at 2-8°C for one year, but dissolved Proteinase K must be stored in aliquots at -20°C. Repeated freezing and thawing of Proteinase K can affect its activity.
3. Buffer VHB must be diluted with 14 ml absolute ethanol before use and stored at room temperature.
4. Buffer RW2 must be diluted with 80 ml of absolute ethanol before use and stored at room temperature.
3. Shelf life
Except for Proteinase K and Carrier RNA, other components of this product can be stored at room temperature (15-25°C) for 12 months, and should be stored at 2-8°C for long-term storage. Proteinase K and Carrier RNA dry powder are transported at room temperature. Please store at -20°C after receiving the test product, and store at -20°C after dissolving.
