Research and Application of Factory Hydroponic Technology in Wheatgrass Greenhouse

Abstract

Conversion of farmland to forest is one of the important policies of China's western development strategy, which is of great significance to the protection of ecological environment in western China. In the context of this era, the traditional grazing-based breeding method that the western region has long adhered to needs to be replaced by the factory-based house feeding with large-scale construction of forage bases. On the basis of a self-developed multi-layer three-dimensional intelligent environmental control system, this study comprehensively optimized the temperature and humidity control system, automatic micro-spraying system, intelligent ventilation system and automatic light filling system, so as to develop an efficient wheat hydroponic planting system. Based on the above planting system, it only takes 7 days from sowing to harvesting. The roots, stems and leaves of wheat grains are all fodder, and 7 kilo-grams of green forage grass can be produced by per kilogram of wheat. In addition, through hydroponic transformation of wheat, protein starch, which is difficult or inefficient to be absorbed in the form of wheat seed, can be transformed into easily absorbed amino acids and glucose. Meanwhile, the vitamin content of green feed is significantly increased, which is of great significance to improve the feed biological conversion rate.
