China leads the world in strawberry cultivation area, but there is still a noticeable gap in average yield, product quality, and farming techniques compared to developed countries. With many regions across the country currently expanding their strawberry farming operations, new growers must be aware of three key taboos to avoid costly mistakes.
First, avoid purchasing seedlings indiscriminately from local markets. Most of the seedlings available are grown on the ground, and their quality can vary greatly. If farmers plant the same variety in the same field for multiple seasons, they risk losing the original variety's desirable traits and increasing the chances of pests and diseases, which can lead to significant losses.
Second, don't blindly introduce varieties without considering your own conditions. Choose varieties that match your local climate, farming purpose, and available facilities. It's best to consult reliable agricultural departments or visit farms directly to inspect and evaluate seedlings. Opt for virus-free planting material to ensure quality and achieve high yields and efficiency. When introducing new varieties, it's also wise to select 2–3 pollination varieties, which can enhance fruit quality, increase yield, extend the fresh fruit supply period, and help with even harvest timing and labor distribution. Pollination varieties should generally make up about 20% of the total planting.
Third, avoid being easily influenced by media hype and repeatedly introducing the same variety, which can result in unnecessary losses. There are numerous strawberry varieties with wide geographic distributions, and some names may refer to the same species. This confusion often arises due to unclear translation, mislabeling, or self-named varieties imported from abroad. For example, "Ryachette" might also be called "New Century 1," "Maria" could be "Carter 1," and so on. Chinese breeders should prioritize varieties that have been officially certified at the provincial level or are widely promoted. After introducing new varieties, it's crucial to maintain strict management and focus on early prevention and control of pests and diseases—this is essential for success. Additionally, adjust the variety structure according to market changes and continuously improve fruit quality to stay competitive and boost economic returns.
Vtm Sampling Tube With Swab
[Sample requirements]
The collected nasopharyngeal swab samples should be transported at 2°C to 8°C and sent for inspection immediately, and the sample delivery and storage time should not exceed 48 hours.
[Testing method]
1. Before sampling, mark the relevant sample information on the label of the sampling tube.
2. According to different sampling requirements, use a sampling swab to sample in the nasopharynx.
3. The specific sampling methods are as follows:
a) Nasal swab: Gently insert the swab head into the nasal palate, stay for a while and then slowly turn to exit. Wipe the other nostril with another swab, immerse the swab head in the sampling solution, and discard the tail.
b) Pharyngeal swab: Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a swab, also immerse the swab head in the sampling solution, and discard the tail.
4. Quickly put the swab into the sampling tube.
5. Break the part of the sampling swab higher than the sampling tube, and tighten the tube cover.
6. Freshly collected clinical specimens should be transported to the laboratory within 48 hours at 2°C to 8°C.
[Explanation of test results]
After the sample is collected, the sampling solution turns slightly yellow, which will not affect the nucleic acid test result.
[Limitations of the test method]
1. For samples that are seriously contaminated due to improper storage after collection, the final test results will be affected.
2. If the sample is not stored at the specified temperature, the final test result will be affected.
