The new tomato production techniques to be introduced today are mainly tomato oscillating pollinator, tomato bumblebee pollination technology, tomato clip, grafting seedling technology, soil disinfection technology, and multi-layer cover early colonization technology. The specific small series will be explained in detail below. I hope to help everyone's tomato planting.
(1) Oscillating pollinator
1. The current problem of exogenous hormones
The problems of exogenous hormones, such as tomato malformed fruit, tomato cavity fruit, tomato-sized fruit, tomato plant, are easy to produce phytotoxicity, work efficiency is low, work is difficult, tomato quality is difficult to guarantee, and there are many kinds of hormone products on the market. In the case of 2,4-D hormones, this hormone does not meet the pollution-free production requirements and is banned by the state, but some companies have changed these banned hormones for sale.
Tomato pollinator structure is the working principle diagram
(2) Bumblebee pollination
(three) tomato clip
Commonly used fruit stem bending diagram in production ( intuitive effect of anti-folding ring )
(4) Grafting seedling technology
(5) Soil disinfection technology
(6) Multi-layer coverage technology
Multi-covering is carried out by means of mulching, deduction of small arch sheds and two-layer curtains to early colonization and avoid the effects of low temperature in spring.
When using multi-layer covering technology, it is generally covered by mulching film, small arch shed and two-layer curtain, which is beneficial to the early planting of tomato seedlings, avoiding the influence of low temperature in spring and promoting the healthy growth of tomato.
The above is about the introduction of new technology for tomato production. I hope that everyone can help. At the same time, you can also pay attention to Huinong.com or download the Huinong mobile app to learn. At the same time, if you have any different information, you can leave a comment below.
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.
