In addition to shading, can the sunshade net help increase the quality and yield of crops? Recently, the team of Jiang Bo, a graduate student from the School of Chemistry and Molecular Engineering of Nanjing University of Technology, developed a "spectrum adjustable sunshade net", which can convert the ultraviolet rays in sunlight into long-wavelength light that is conducive to photosynthesis while shading, thereby improving the The quality and yield of crops can help farmers get rid of poverty and increase their income. The results of this project won the first prize of the 6th Jiangsu Province "Internet +" College Students Innovation and Entrepreneurship Competition.

Brown White Shade Net 100GSM

6-needle shade net in brown and white with tonal stitching. The sunshade net is made of polyethylene (HDPE) material with about 1-5% UV stabilizer and antioxidant. The size can be customized, and its maximum width can reach 12 meters. The weight per square gram of the shading net is 100 grams, and the shading rate can reach more than 90%. The brown and white shade net is actually more orange in color, which is a more energetic color. Most customers will choose this color as a playground.

Plant growth requires photosynthesis, but not all light in sunlight is beneficial for plant growth. In the photosynthesis of plants, the pigments in the chloroplast mainly absorb the red and blue light in the sunlight, and the excessive ultraviolet rays in the sunlight are actually not conducive to the growth of plants. In response to this problem, Jiang Bo's team, a graduate student from the School of Chemistry and Molecular Engineering, Nanjing University of Technology, under the guidance of his mentor, Professor Han Zhi, cooperated with Jiangsu Huachang Textile Co., Ltd. ”, which can convert ultraviolet rays in sunlight into long-wavelength light required for plant photosynthesis, reduce the damage of ultraviolet rays to plants, convert unfavorable light into effective “photofertilizers”, and improve the efficiency of plants in photosynthesis. "While shading and cooling, this net can automatically adjust the wavelength of light passing through the shading net, convert the ultraviolet rays in sunlight into long-wavelength light that is conducive to plant photosynthesis, improve the utilization rate of light, and promote the growth of crops. So as to improve economic efficiency." said Mr. Korea Zhi.

Shade nets are agricultural consumables widely demanded by agriculture, forestry, fishery and animal husbandry. However, while the ordinary sunshade net is shading, it will also weaken the effective absorption of light by plants, affecting the effective photosynthesis of some plants, which will lead to quality problems such as weak and slender fruits. In response to market demand, Jiangsu Huachang Fabric Co., Ltd. approached Korea Zhi for scientific and technological cooperation to develop a new type of sunshade net. Under the guidance of Korea Chronicle, the project team led by Jiang Bo developed a "light-converting agent" with independent intellectual property rights after two years of technical research. Use it to replace the pigments in the ordinary color masterbatch to prepare the color masterbatch. On the basis of not changing the existing spinning process, a "spectral adjustable shade net" is produced.

"Based on the principle of light conversion, the product absorbs ultraviolet rays and emits long-wavelength light, just like 'breathing'. It can not only promote the photosynthesis of plants, but also effectively reduce the damage to the sunshade net caused by strong light." Jiang Bo said, Tested by professional institutions, the service life of the product can reach 10 years, and the material of the sunshade net can be reused without adverse effects on the ecological environment. "Our new type of sunshade net was first applied to the agricultural experimental base in Jurong, Jiangsu." Jiang Bo introduced that the base is located in Tingzi Village, Xiashu Town, Jurong. The farmland of the experimental base is mostly yellow clay, and the soil quality is poor. low. The products of the project are firstly used in cherry tomatoes planting. "From the perspective of planting effect, compared with conventional planting, the cherry tomatoes grown with our products are of better quality, sweeter in taste, and the price is 2-3 times that of ordinary cherry tomatoes. Mu can help fruit farmers increase their income by more than 20,000 yuan." The project team innovatively extended the sunshade net to food planting. In the agricultural base, the research on rice planting application of Nangeng 5055 was carried out. Few pesticides are used in the planting process, and it belongs to green organic rice. Judging from the planting results of the two seasons, the yield per mu of rice can be increased by about 100 kilograms. If the unit price is calculated at 10 yuan per catty, excluding the cost of the sunshade net, it can help farmers increase their income by more than 4,000 yuan per mu.
