Agricultural grower Zhang Gongguo

Zhang Gongguo, who started his career with 50 yuan and walked with blistering feet, came to Zhangjiagang in 1997. With 50 yuan in mind, Zhang Gongguo came to the Qingcao Lane Wholesale Market. With this 50 yuan, he bought an iron pot and other tools, bought raw chestnuts on credit from the market, fried them and sold them in the wholesale market. "the wholesale price of raw chestnuts is 8 yuan / kg, and that of cooked chestnuts is 16 yuan / kg. There is a price difference of 8 yuan per kilogram." On that day, Zhang Gongguo unexpectedly sold more than 100 kilograms of hairy chestnuts, excluding the cost and made more than 400 yuan. With the money earned from fried chestnuts, Zhang Gongguo rented stalls in the wholesale market and started a wholesale vegetable business.

After two years of wholesale business, Zhang Gongguo decided to grow his own vegetables. That year, Zhang Gongguo contracted 50 mu of land and began to grow sugar cane and chili peppers. Under his careful care, sugarcane is growing well. "in August of that year, just when the sugar cane was about to be harvested, we had a big typhoon." In the twinkling of an eye, a large area of soon-to-mature sugarcane was blown down. "despite the typhoon, there was very little sugarcane produced locally at that time, and our sugarcane was very popular, with a harvest of 4000 to 5000 yuan per mu." Excluding investment, the net income per mu is about 1500 yuan, which greatly encouraged Zhang Gongguo.

With the change of new varieties, the output has increased by more than 30%. For the first time, Zhang Gongguo made up his mind to make up his mind to do enough work on vegetable cultivation. "although it has made a good profit, according to my years of wholesale experience, due to the influence of the market, seasonal vegetables grown in traditional ways generally do not sell at a good price." Zhang Gongguo said. Therefore, he decided to plant in a greenhouse so that his vegetables and fruits could be put on the market earlier in order to achieve greater economic benefits.

Investment is the first step in the development of greenhouse planting. "if it is a bamboo structure, a greenhouse costs about 4000 yuan; if it is a steel pipe structure, the investment of each greenhouse is more than 10,000 yuan." However, high investment has also brought high benefits to Zhang Gongguo. "take greenhouse watermelons as an example. Generally, the seeds are sown in late January and can be harvested in mid-May, while ordinary watermelons will not be on the market until late July. " Last year, when his greenhouse watermelons went on sale in May, the wholesale price per kilogram reached 3.6 yuan. "moreover, in the greenhouse, it can reach 40 °C during the day and 15 °C at night, so the quality of watermelons grown in the temperature difference environment is much better than that of watermelons grown in the usual way." The average income per mu of watermelon in greenhouse is about 8000 yuan, which is much higher than that of traditional planting. " "for high-input facility agriculture such as greenhouse planting, it is very important to find high-yielding and efficient varieties." Introduced by Zhang Gongguo. With the addition of new varieties of facilities, the benefit will be better. "look at the zucchini we grow now. I introduced it from Beijing in 2006. A single zucchini can produce 7 to 10 kilograms, and the yield per mu has increased by more than 30 percent over the original variety, reaching 600 kilograms." Not only that, the new variety of zucchini has a good appearance and high quality. "it sold more than 100,000 yuan a month in March."

After these zucchini leave the field, celery will be planted in these greenhouses, and all the film in the greenhouse will be removed and towel gourd will be planted next to the steel pipe. " Zhang Gongguo said while checking the growth of zucchini. "the towel gourd seedlings have been raised and will be ready for transplanting in about 20 days." In addition to making full use of greenhouse facilities, there is another important reason why celery is planted under towel gourd. "celery is a low-temperature crop. It stops growing when the temperature reaches 25 °C and begins to age after 30 °C." Planting towel gourd on the top of celery can effectively reduce the temperature and solve the technical problem of annual production of celery.

In this greenhouse, a film is laid close to the ground, another film is covered 50 centimeters from the ground, and there is a greenhouse film on the outermost. Is there something strange growing in it? "this is called the technique of interplanting chili peppers with three-film mulching sugarcane." Introduced by Zhang Gongguo. Plant chili at the bottom, and then plant sugar cane next to it. Three-layer film can effectively ensure that sugarcane sprouts and appear on the market in advance, and then interplant with pepper to further improve the utilization rate of land. "Last year, we planted more than 50 greenhouses in this way, and the output value of each greenhouse was more than 10,000 yuan." The benefit is obviously higher than that of separate planting.
