"Now it is about a week before the Shine-Muscat is mature. Merchants have come to our village to book, and the maximum purchase price is 16 yuan / kg." in late August, we entered the Shine-Muscat vineyard of Li Aimin, Yongsheng County, Lijiang, Yunnan Province, and Li Aimin introduced it to us.

In 2018, Li Aimin and his wife leveled the land and built a vineyard. When the fruit growed up gradually, his wife found that the grape leaves turned yellow and the newly grown leaves has scorched edges, and the trees were getting weaker. After careful observation and comparison, Li Aimin found that the soil in his vineyard was seriously hardened, and the grape root system became brown, rotten, dry and without capillary roots. "I often pay attention to soil problems through Internet, television and other platforms. After discovering these situations, I preliminarily judge that there is a problem with the soil.”

Subsequently, Li Aimin contacted Qingdao Dorcas Biotechnology Co., Ltd and invited their experts and staff to test the soil in their own garden. "After measurement at that time, it was found that the PH of soil was 5.8, serious acidification, serious soil hardening and hypoxia of grape roots. These were caused by excessive use of chemical fertilizer. If soil purification, repair, conditioning and health care were not carried out in time, the fruit trees would become sickly, the output and quality of fruit would decline, and even cause the death of fruit trees.

After the disease was symptomatic, experts instructed to use seaweed organic fertilizer to purify, repair and health care the soil in the garden when applying fertilizer in the autumn of 2019 and spring of 2020. In the spring of 2020, after the grape leaves grow, the soil hardening phenomenon in the garden basically disappeared, and white capillary roots grew again on the original rotten and dry roots.

This year is the third year that Li Aimin used organic seaweed fertilizer. After comparing with the grapes planted by his neighbors, it is found that the vines in his garden are robust, with large thick and green leaves, large grape particles,glossy color, thin skin, rich taste and strong flavor. The grain weight is more than 12g, and the weight of each string is more than 600g, which is worthy of learning and reference for fruit farmers.
