Modern Technology Application and Research on Large-scale Production of Broccoli in Open Field
In order to improve the technical level of large-scale vegetable production of the land for returning forests to farmland in Beijing,enhance the quality of cultivated land,reduce production input and improve planting efficiency,a modern technology integration suitable for large-scale production of broccoli in open field has been summarized based on actual production situation.In the large-scale production of broccoli in open field in spring and autumn,by using modern technologies such as intensive raising seedling,labor-saving machinery and equipment,integration of water and fertilizer and unmanned aerial vehicle(UAV)for plant protection.Combining with timely harvesting after production,the average annual yield of broccoli in open field can be achieved with 2 810 kg per 667 m2 and a total output value of 19 680 yuan per 667 m2.Moreover,the cost of input was reduced by 34.59%per 667 m2 compared with traditional small-scale farmers planting,promoting the sustainable development of vegetable large-scale production.
