The "Li greenhouse" closest to farmers

Li Chunsheng gives technical guidance in the greenhouse.

Twelve months a year, he lived in the countryside for 10 months, helping farmers build greenhouses and teaching farmers to grow vegetables by hand; in the early 1990s, when ten thousand yuan households were rare, he directed vegetable greenhouses with an annual income of 15,000 yuan. Farmer brothers are affectionately called him "Li greenhouses," Ji County rural areas are still circulating "buckle shed to find 'Li greenhouse'"such a saying.

He is Li Chunsheng, deputy director of Vegetable Station of Tianjin Ji County Agricultural Bureau. For more than 30 years, he has been working on the front line of vegetable technology research, promotion and service. He has successively won the first prize of Agriculture, Animal Husbandry and Fisheries Harvest Award of Ministry of Agriculture, the second and third prizes of scientific and technological progress of Tianjin City, etc. In 2012, he also won "Special Government Allowance of the State Council". The vegetable industry in Ji County has also developed into a characteristic industry under the efforts of him and his colleagues. The area of vegetable facilities accounts for 1/5 of Tianjin City. Cucumber, beans and other varieties in Ji County are supplied to Beijing market in large quantities.

Just look for "Li Da Peng" when you buckle the shed.

Speaking of the nickname "Li Dapeng", it dates back to more than 20 years ago. It was in 1993 that Ji County, Tianjin, introduced efficient energy-saving solar greenhouse technology, ending the history that local winter vegetables could not be produced, and it was three Shandong farmers who brought this technology. Li Chunsheng, 30, has worked as an agricultural technician at the vegetable station for many years. He was surprised and dissatisfied to learn the news."Shandong farmers can do it, why can't I?" Then he made a bold decision: stay in the village to learn technology and help farmers build greenhouses.

"In 1994, Shandong Shifu left, and Li Chunsheng began to independently guide the village. He was responsible for the construction of 24 greenhouses and vegetable production in Linzhuanghu Village." Li Chunsheng stayed at the shed site day and night. After three months, the greenhouse was finally built. Then there is the planting management of vegetables. Li Chunsheng, a technician, is not afraid at all. He turns from shed to shed every day to guide farmers in vegetable seedling cultivation and cultivation management.

A year later, a shed income of 15000 yuan, farmers laughed, Li Chunsheng heart of a stone landed. "In the past, Tianjin couldn't eat fresh cucumbers and tomatoes in winter. During the Spring Festival that year, cucumbers cost 10 yuan and 3 jin. On ordinary days, 1 yuan was more than 1 jin. Farmers who planted greenhouses became rich at once."

Li Chunsheng was affectionately called "Li Greenhouse" by farmers, but he did not succeed and retired. He stayed for 8 years, guiding 630 farmers in 28 villages in 6 towns and towns of Ji County to build 3650 mu vegetable greenhouses and riding bicycles for more than 30,000 kilometers.

Don't stay on imitation

Li Chunsheng's greenhouse road did not stop at imitation and reference, but carefully studied, which promoted the leap-forward development of facility agriculture technology in China.

"In the past, greenhouses were insulated externally. Farmers had to climb up and clean them when it snowed. When it rained, they couldn't pull up the straw mat. If the insulation straw mat was inside the shed, it would be fine." After more than 4 years of research, in 2005, Li Chunsheng completed the structural design of the new solar greenhouse for the first time, and built the first solar greenhouse with internal insulation in China.

The successful development of high efficiency energy-saving solar greenhouse structure with internal insulation creates a new history of solar greenhouse structure in China. The lowest temperature in the greenhouse is 3-5℃ higher than that in the ordinary second-generation energy-saving greenhouse, the vegetable yield is increased by more than 30%, and the labor resources are saved by more than 20%. In 2008, the greenhouse was named "Ji Chun type heat preservation quilt built-in solar greenhouse" by Professor Chen Qingyun of China Agricultural University.

"The inner insulation greenhouse saves us a lot of things, and the effect of heat preservation and production increase is also good. Two sheds per family, easily earning more than ten thousand yuan a year." Tang Tuo Zhuang village farmer Li Shuangliang said. In recent years, Li Chunsheng has also promoted independent innovation technologies to Beijing, Jilin, Liaoning, Ningxia and other nine provinces and cities, with a cumulative promotion of 120,000 mu, driving farmers everywhere to increase their income by more than 600 million yuan.

In 2012, Li Chunsheng presided over the construction of Ji County Modern Agricultural Science and Technology Demonstration Park. Since then, he moved his work place here and "carefully cared for" 63 modern greenhouses. Colleague Wang Hongyun said: "When the park built the shed, Li Chunsheng did not trust to hire people, greenhouse positioning, drawing stretching ruler are their own work."

In winter, the greenhouse is as fresh as spring and green. On the way to leading the farmers of the whole county to become rich, Li Chunsheng's dream is also constantly upgrading. "Ji County has unique geographical advantages and rich tourism resources. We should vigorously develop characteristic agriculture. Recently, we have just introduced long mulberry fruit, pineapple and other facilities fruit trees. The viewing effect and economic benefits are good. Next, we must introduce management and cultivation techniques to make these fruit trees the next fulcrum for farmers to become rich." Li Chunsheng said.
