This seemingly inconspicuous “cloth” is actually a combination of an “intelligent insulation blanket” and a “micro growth regulator”. It creates a more favorable growth environment for crops by changing traditional planting methods, allowing them to be launched early and sold at a good price.
Let’s uncover its secrets together.
Three magic weapons: the “black technology” of PP spunbond non-woven fabric
PP spunbond nonwoven fabric can become a “market accelerator” mainly due to its unique three abilities:
1 ️.Efficient insulation, creating a “warm room” effect: Its core advantage is the significant “insulation and warming” effect. As a harvest cloth that directly covers crops (i.e. “floating cover”), it can slow down ground heat loss and increase the temperature around crops by about 2-4 ℃ . For seedbeds with thin and weak stems, it can also increase the ground temperature by 1-2 ℃. This temperature is particularly crucial for breaking the spring chill and promoting healthy crop growth, just like putting a “warm coat” on seedlings, directly accelerating their physiological processes.
2. Intelligent “microcirculation” creates the best environment: It is not completely sealed like plastic film, but has a unique “microporous structure”, forming an intelligent microcirculation system:
Slow rise and slow fall, gentle growth: During the day, the temperature is about 5 ℃ lower than plastic film, which can avoid burns; At night, it can maintain a stable environment that is 1-2 ℃ higher.
Automatic humidity adjustment : allows water vapor to slowly pass through, effectively reducing the humidity inside the shed by about 5% -7% , greatly reducing the occurrence of diseases such as gray mold.
Accurate Light Transmittance : Maintaining a light transmittance of about 30% -60% , which can ensure photosynthesis and avoid strong light burns.
3 ️. Providing comprehensive physical protection: In addition to regulating “temperature, light, water, and air”, it also serves as a multifunctional physical barrier, safeguarding crops from the source:
Preventing disasters: It can effectively resist the invasion of harsh weather such as cold winds, frost, hail, etc.
Physical pest control: Used in the early stages of seedling cultivation, it can directly block pests such as aphids and reduce the use of pesticides.
Inhibit weeds : In orchards and other scenes, black PP non-woven fabric (also known as “weed proof fabric”) can effectively inhibit weed growth due to its extremely low light transmittance.
How to make strawberries and vegetables “win at the starting line”?
In actual planting, PP spunbond non-woven fabric has effectively helped farmers seize market opportunities through the following methods:
Strawberries: Morning Market, Higher Quality
The early ripening effect is significant: After application coverage, it can promote the strawberry ripening period to generally advance by 7 to 10 days, and in some cases, it can even advance by about 2 weeks, allowing fruit farmers to seize the high priced early market. In the process of nurturing seedlings in protected areas, it can also effectively reduce diseases and overgrowth, and improve the quality of seedlings.
Improving Quality: Bags made of non woven fabric can also be directly hung on fruits, creating a superior growth “microenvironment” for strawberries. While being waterproof and breathable, it can significantly increase the content of soluble solids, anthocyanins, and vitamin C in the fruit, making strawberries sweeter, more fragrant, and more vibrant.
Vegetables: Grab the “fresh” machine, high returns
Significantly advanced listing time : Compared to open field cultivation, it can advance the listing of various vegetables by 5 to 15 days . More innovative growers have utilized the “small arch shed” method to bring vegetables such as beef heart vegetables to the market more than a month in advance, accurately filling the market gap and doubling the selling price.
Significant increase in production and income: The improvement of microclimate has also brought about a significant increase in production. For example, the yield of overwintering leafy vegetables can be increased by 2 to 4 times. Vegetable farmers in Jiangsu also stated that non-woven fabric covered spinach, celery, and other vegetables not only have good appearance and high selling prices, but can also achieve good benefits such as a 20% increase in yield per mu and a 15% increase in income.
Summary
The application of PP spunbond nonwoven fabric in the agricultural field is like a ‘micro revolution’. It does not rely on complex equipment, but injects technology into a thin layer of fibers, cleverly changing the “microclimate” above the heads of seeds and seedlings, pressing the accelerator button for their vigorous growth. From “plastic sheeting” to “smart insulation blankets”, this lightweight material is redefining the boundaries of agriculture in the closest way to the land.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
