Wang Haiping: grow organic vegetables on the "tree"

Wang Haiping, a farmer of Shicheng neighborhood Committee in Sushan Township, Duchang County, has been innovating around planting and breeding for more than 20 years, and has obtained one invention patent and four utility model patents. and use their own inventions to explore a new mode of integration of planting and cultivation-- planting organic vegetables on "trees", which not only reduces the cost of planting and breeding, but also greatly reduces environmental pollution.

Recently, the reporter came to Wang Haiping's pig farm and saw a greenhouse on the roof of a three-story pig house with an area of about 2 mu. Chinese cabbage is planted on the "trees" in the greenhouse, and the rows of "vegetable trees" are in good order, like a "forest". The greenhouse is very clean and free of mud, which is pleasing to the eye. "this is a standardized planting device for three-dimensional pipeline micro-irrigation vegetables invented by me. It is 1.2 meters high. It has obtained a patent for utility model at the end of 2015, and has applied for a patent for invention." Wang Haiping said, "by deeply fermenting pig excreta and matching it with uncontaminated soil, and then putting it into a planting device to grow Chinese cabbage, we can control the growth of Chinese cabbage through precise fertilization and water supply. The cabbages grown in this way are organic vegetables with a price of more than 20 yuan per kilogram and demand falls short of supply. "

Wang Haiping, 49, went home to work as a farmer after graduating from junior high school and learned excellent farming skills through China Agricultural University. In 1995, he began to raise pigs on a large scale, and in 2004 he established Duchang County Creative Industry Co., Ltd. In the process of raising pigs, he actively explored new methods and established the 666mur108 pig raising system innovation project (6 control, 6 points and 6 combinations, a total of 108 items), which was not only beneficial to the prevention and control of pig diseases, but also saved costs and improved economic benefits. At its peak, his pig farm produced 15000 pigs a year.

In order to explore the new mode of integration of planting and breeding, he innovated boldly and successively invented "a kind of multi-stage dry-wet separation device for excreta of pig house", "automatic timing and quantitative feeding device for fattening pigs", "mixed type of energy-saving and environmental protection ecological pig house for planting and breeding" and so on. and obtained four practical model patents. Among them, "planting and breeding mixed energy-saving and environmental protection ecological pig house" also obtained the invention patent.

The standardized planting device of three-dimensional pipeline micro-irrigation vegetables invented by him has achieved success in planting pakchoi, chili and other crops over the past two years. Using this device to grow vegetables in the greenhouse, the unit area is 4 to 6 times that of ordinary greenhouse vegetables, and the benefit is even higher. "according to different crops with different components of soil, through this device accurate fertilization, water supply, the whole process of crop growth control, not only without any pollution, but also save land, fertilizer, water and efficiency." Wang Haiping is very satisfied with his invention.
