A bag culture
system for large-scale production of solanaceous vegetables comprises a plurality of culture troughs, a plurality of culture bags, a water inlet
pipe, a reservoir, a water pump, a fertilizing device, a filter, a
drip irrigation main
pipe, a plurality of
drip irrigation branch pipes and a plurality of emitters. The culture troughs are formed in parallel on the floor of a
solar greenhouse by recessing. Two rows of upright culture bags are disposed in each culture trough. The reservoir is located inside the
greenhouse. The water pump is disposed in the reservoir, and an outlet of the water pump is connected with a liquid inlet end of the
drip irrigation main
pipe. An outlet end of the fertilizing device is connected with a liquid inlet end of the drip
irrigation main pipe. The filter is disposed on the drip
irrigation main pipe. The rear of the drip
irrigation main pipe is arranged above one ends of the culture troughs. One drip irrigation
branch pipe is disposed above each row of culture bags, and one ends of the drip irrigation
branch pipes are connected with the drip irrigation main pipe simultaneously. Each drip irrigation branch pipe is provided with the emitters, while each emitter is above a round hole of each culture bag. The bag culture
system has the advantages that production environment can be improved, water and
fertilizer can be economized,
utilization rate of
fertilizer is increased, spread of soil-borne diseases is avoided, and the like.
