The first evolution of the new elevated soilless cultivation technology of strawberry in Yangtian agriculture in Hangzhou

Recently, Hangzhou Yangtian Agricultural Development Co., Ltd., a modern agricultural enterprise, was introduced into Evolutionary Town, Xiaoshan District, Hangzhou City, and a high-tech agricultural innovation demonstration base was established in Huajiadian Village of the town. Strawberry viaduct soilless cultivation optimization technology has been successfully adopted.

Walking into the modern intelligent greenhouse of 6000 square meters of Yangtian agricultural demonstration base, rows of strawberry elevated soilless cultivation facilities are bright in front of people's eyes. "Don't underestimate this elevated soilless cultivation optimization technology. We are the first in China. This strawberry planting technology can improve the quality of strawberries, double the output, and save half the land area." Zhu Hanliang, chairman of Hangzhou Yangtian Agricultural Development Co., Ltd., said to the author.

It is understood that this set of elevated soilless cultivation strawberry technology was newly introduced from Japan with an investment of 6 million yuan by Hangzhou Yangtian Agricultural Development Co., Ltd. through a digital program control device, the formula, dosage and drip irrigation time of high-efficiency fertilizer are controlled throughout the process, which has obvious advantages over traditional strawberry planting methods.

Traditional strawberries planted on the ground not only bend over to work intensively, but also are difficult to avoid the invasion of diseases and insect pests. The outstanding advantage of elevated planting is that plants have good daylighting, can effectively control the temperature and humidity of plant roots, and create the best growth conditions for melons, fruits and vegetables.

Now, digital information technology has rapidly penetrated into various industries. Facility agriculture or high-efficiency agriculture created by Yangtian agricultural demonstration base is actually digital agriculture, which is also the core technology system of the whole demonstration base. During the visit, the author found that there are two pipes in each row of viaducts, respectively for heating and supplying water and nutrients, directly to the roots of plants, and the temperature and humidity are digitally automatically controlled. "the proportion of nutrients in each growth stage of the plant is different, so that the utilization of resources is maximized, which is very time-saving and labor-saving, and makes managers relaxed and happy," says Zhong Hanliang.

According to reports, because the optimization control technology system of elevated soilless cultivation process adopts program-controlled drip irrigation to supply fertilizer, strawberry can be managed in stages according to the water and nutrients needed for strawberry growth, nutrient promotion management can be carried out in the early growth stage and flower bud differentiation period of strawberry, and strawberry sugar content and acidity adjustment can be managed during fruit ripening period, so as to revolutionize the quality and yield of strawberry. For example, the yield per mu of traditional strawberry planting is generally about 3500 jin, while the new model of Yangtian planting strawberry yield per mu can be increased to more than 7000 jin. In addition, the traditional soil cultivation is limited by soil conditions, there are continuous cropping obstacles, land utilization rate is low, elevated soilless planting is not limited by soil conditions, avoid continuous cropping obstacles and improve land utilization rate.

After tasting the Jiale Man strawberries produced by Yangtian Agricultural demonstration Base, the author found that unlike the fruits grown in the greenhouse, the strawberries here are sweet with a slight sour taste, sufficient moisture and delicate taste. "the taste is good, which is related to the management of strawberry sugar increase and acidity adjustment," the company's marketing staff said. "at present, because the output is not very large, this kind of elevated soilless cultivation strawberries are mainly supplied to high-end fruit supermarkets. Although the price is 50% higher than ordinary strawberries, there is still a great market demand."

Recently, relevant experts from the Development Research Center of the State Council came to conduct research and had exchanges with the Secretary of the Party Committee of the Evolutionary Town to Xuehua and the mayor of the town, Cao Yifeng. Experts fully affirm the new paradigm of Yangtian farming demonstration base, which aims at "happy agriculture", introduces funds and talents, and vigorously develops facility agriculture by relying on science and technology. in particular, the innovation of "greenhouse intelligent greenhouse + substrate cultivation elevated facilities + intelligent fertilizer and water control high-tech automatic agricultural planting system" is full of praise.

Born in a rural family, Zhong Hanliang has been exposed to the traditional peasant labor form of "facing the loess and facing the sky" since childhood, and the inefficient and extensive agricultural model is also the main reason for poverty and backwardness in rural areas for many years. Therefore, "being a farmer can also be happy and have a high income" has always been a dream pursued by Zhong Hanliang. This dream has gradually become a reality with the establishment of Hangzhou Yangtian Agricultural Development Co., Ltd.
