In the middle of the winter season, when strawberries were in bulk, and in the warm sun, they were shared with their families in a bowl of fragrances and red-hot strawberries, a small “romantic” in the air of the end of the year。
However, most of the knowledge of strawberries in the general population is derived from commercial shelves, which are supported by scientific and technological power from breeding, planting and processing。
Early market, high-yielding, high-quality strawberry varieties "kangsu"
Strawberry is an important agricultural industry in my province, and according to 2021 statistics, i own about 300,000 acres of strawberries, the fourth largest area in the country. The growth of thailand is one of the first areas in which i have been able to grow strawberries, but in recent years, strawberry varieties have become monolithic and inefficient, becoming a problem for local strawberry growers, and the area under cultivation has been reduced from a peak of over 5,000 acres to about 1,500。
“the choice of strawberry varieties can significantly affect the income of growers. The economic risks to farmers are high when the growing strawberry varieties are structured in a single form and marketed in a concentrated manner at a similar time, at prices that do not go ahead.” in september of this year, the team of experts from the agricultural college of jiangsu province, guan ling, a deputy researcher at the fruit tree institute of the agricultural college, selected two very early and disease-resistant varieties of “twilight snow” and “twilight gold 66”, which were brought to the fore for pilot roll-out and distributed to local growers over 18,000 seedlings。
Strawberry seedlings planted in september have grown and blossomed, and have come to the strawberries shed of the family farm where the fruit and vegetables grow, green oil, and green leaves with a white, powdered strawberries, which the farm introduced this year as a variety of “smelling snow”, which looks as if the colour of the fruit is like a baby's blistering cheek, bites it down and sends out a fresh smell of peach。
Purple snow
In november of this year, the head of the farm, lu-chou, won a gold prize in the jiangsu purple gold cup, a variety of gold and snow. "i think it's an early, productive and tasteful species of purple snow." lubula raised a strawberries seedling and told reporters that “the ‘twilight snow' is very productive, and you can see that in this sequence, eight fruits have been produced. In september this year, the plant was scheduled to enter the fertile season in mid-november, and the purchase price was 50 pounds
Guan ling wrote to the journalists about the high production of "smelling snow" with at least three nuts on a seedling, with an acre production of at least 3,000 pounds at the average sale price and an acre of $45,000. “the white strawberries such as `twilight snow', which are expensive, fit the mind of the consumer, are expected to rise to the second fruit before the spring season, and there is room for price increases.”
Locally appropriate, planting technology-enabled strawberry cultivation “scaling efficiency”
A quality strawberry is grown, seedlings are the basis, and soil and technology are the key. Since 2018, the strawberry innovation team of the provincial agricultural college has been developing a strawberry accelerator semi-basic model, which has been in progress for four years and was replicated throughout the province in 2022。
“the advantages of the traditional ground-based seedling and high-stolen matrix cultivation models are combined.” wang qinglian, deputy researcher at the fruit tree institute of the academy of agricultural sciences of jiangsu province, described the high-soft semi-matrix cultivation pattern at a height of 40-80 cm, with 10-30 cm of soil below the planting tank, on top of which 10-30 cm fills, 20 cm from the top of the planting tank, with an anti-worm net shield, which is then filled with the matrix. The cost of construction varies from $5,000 to $30,000 per acre depending on the size of the containment material。
“structures such as this allow high-soft semi-matrix cultivation models, on the one hand, to keep the water warm and to facilitate the absorption of nutrients by strawberry roots; on the other hand, past strawberries need to bend, labour intensive, and high-soft semi-matrix cultivation models need not bend, save energy, clean and light. In the past, two people managed 10 strawberries, while two people managed 15 strawberries, which greatly improved their efficiency。
Changes in the same grower's application of the hypersynthetic semi-matropod model
Since 2022, the provincial agricultural institute's fruit-trees have been working with the local community on the implementation of a coordinated extension programme for major agricultural technologies (snapberry light-simplified farming) and piloting of the high-snap semi-basket strawberry cultivation model in response to the problem of local soil salinity and the difficulty of strawberry cultivation. “this cultivation model has performed well in the water, and the pilot plantation has built a high aluminum substrate of about 40 centimetres, using a low cost of $5,000/acre, which, in the case of the same variety, rose from less than $10,000 to about $70,000 today.” wang qinglian said. At present, this cultivation model has been replicated throughout the province, including in the water districts of nanjing city, puguchi district and the town of yujiang, and has been exposed to radiation in areas outside the provinces of shandong chinin, niigata, etc。
Strawberry cultivation in greenhouses requires “relevance efficiency”, and green control is another indispensable technology, which is being promoted and promoted throughout the province at the provincial agricultural college. “green control techniques have many facets, first, to select a pathological strawberry species that can reduce the use of drugs from the source; secondly, because strawberries are intolerant, they need to treat the soil every year to enhance soil organicity; and also to develop biological control techniques, such as insect treatment and the prevention of strawberry pests such as fungus.” wang qinglian described green prevention and control techniques that not only enhance strawberry quality, but also provide food security for consumers。
“the nutritional accumulation of strawberry fruit requires some temperature differentials, and the continuous high temperature and heavy rainfall of jiangsu this autumn did have an impact on the quality of strawberries, leading to the possible acidity and smallness of the pre-november fruit, as well as on purchase prices. In order to minimize the influence of external factors, it is recommended that the conditional berry farmer should have a false or cold nursery at the end of the period, that the planting period should be protected, that the temperature of the day and night should be increased and that the nutrient accumulation of the buds in the plant should be ensured。
Extending the strawberry industry chain and opening new ways of generating revenue
Strawberry production includes processes ranging from seedling to planting to fresh fruit sales, and in recent years, the development and production of strawberry processing products has led to a further extension of the strawberry chain。
“although most of the strawberries are currently fed directly, there is still good market potential for processed products.” zhou zhong zhou, researcher at the agricultural processing institute of the agricultural institute of jiangsu province, stated that, owing to the short harvest season of fruit, many fruits could rot when they were not sold in time, resulting in waste of up to 20-30 per cent. The processing of products such as dry fruit, fruit and wine, jam and juice not only reduces waste, but also increases product value added and increases the market life of seasonal fruits。
Strawberry processing techniques, which appear simple, involve complex processes. Zhou zhou zhou zhongxian describes, for example, a snack “frozen strawberries”, which is well known to consumers, not only for seeding and corroding after harvesting, but also for maintaining a bright colour while safeguarding food safety, but also for drying under freezing conditions. The process is highly power-consuming and costly, and how to calculate the optimal drying time and balance costs and quality is key to technology。

Vegetable fermentation of strawberry juice and functioning strawberry fruit wine are another important area of strawberry processing. The choice of a suitable processed strawberry variety can be combined with a fungus to produce functional strawberry products. The application of the fungi in dairy products such as yogurt is relatively mature, but its introduction into the processing of fruit and vegetables has been a relatively innovative process in recent years。
“despite technological breakthroughs in strawberry processing, many small and medium-sized processing enterprises currently established by growers, limited by factors such as the small size of farms, still face difficulties in marketing brand names to effectively market their products.” however, the flourishing of rural tourism in jiangsu offers new opportunities for strawberry processing products. Zhou zhou zhong chong suggested that the new forms of rural tourism, such as strawberry production bases, could be used to produce some strawberry-specific products, combining strawberry processing products with new forms of rural tourism, such as “farm-carrying”, could further widen the market for processed products, and it was hoped that a local brand of “agricultural brigade” would be created。
