The 6,000-kilos Kiwifruit Fairy Orchard in Yanjia Town is a standardized demonstration park and is also a business card for Dujiangyan Modern Agriculture. Every time a kiwifruit is picked, visitors come for sightseeing, photography, and riding. As the chairman of the kiwifruit farmer professional cooperative, Wang Fengsheng has a great responsibility for the quality of the fruit.
Since 2005, the village of Jinsheng where Wang Fengsheng is located has transformed from traditional agriculture into the Kiwifruit Park. Wang Fengsheng painstakingly studied kiwifruit planting techniques and began to use farmyard fertilizers to increase soil organic matter very early. However, it is difficult to solve the problem of farmyard manure.
In 2009, under the recommendation of experts from the Academy of Agricultural Sciences, Wang Fengsheng came into contact with bio-organic fertilizers. Compared with ordinary organic fertilizers, bio-organic fertilizer is fully cooked, does not burn roots, not rotten seedlings, the most important is to add beneficial bacteria, can increase the activity of the soil itself, increase nutrient absorption capacity, and control harmful bacteria, reduce disease occurrence .
On September 26, Wang Fengsheng told reporters that he is now producing 2 tons of organic manure per mu, and only one pound can be used for a fertilizer. The orchard's soil organic matter has reached 3%, which is a relatively healthy and fertile soil.
Wang Fengsheng also has an innovation: Every few years, the old roots of fruit trees are cut off, so that new roots with strong absorption capacity can be fully grown, thereby increasing the efficiency of fruit trees in taking soil nutrients. "Although it is more time-consuming, the effect is obvious. From the growing situation, we can see that its absorption capacity has increased a lot," he said.
In 2011, Wang Fengsheng used evasive cultivation techniques in grape planting on kiwifruit to reduce the occurrence of pests and diseases. He has applied for the certification of organic kiwifruit. Because of the good quality of the fruit, his orchard's net profit per mu can reach 30,000 yuan.
“Now the whole park has adopted soil testing formulas, and after discussing the advantages and disadvantages with the villagers, they are willing to use bio-organic fertilizers, which cost between RMB 1,000 and 2,000 yuan per ton, and are not much higher than ordinary fertilizers and organic fertilizers. Currently, they are The use of fertilizer has covered several thousand acres of the surrounding area." Wang Fengsheng said that in the next step, he intends to continue to explore techniques for soil improvement that are effective and easily adopted by the villagers so that soil organic matter content can be maintained at 3%-5% in an all-round and stable manner.
