Bag culture system for large-scale production of solanaceous vegetables

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of facility agriculture, in particular to a bag culture system for large-scale production of solanaceous vegetables. Background technique [0002] Soilless cultivation technology is a technology widely used in facility agriculture in the world. It obtains the most suitable growth conditions for plants by changing the natural environment, and satisfies the various elements required for crop growth to the greatest extent, so as to increase crop yield and improve product quality. , to extend the growing season and improve efficiency. At present, more than 100 countries in the world have used soilless cultivation technology for modern greenhouse production. Soilless cultivation is mainly divided into three categories: substrate cultivation, hydroponics, and aeroponics, among which substrate cultivation is the most widely used. The main device that matrix cultivation is really applied to facility agricultural p...

Problems solved by technology

The bag culture technology that my country is used for the large-scale production of solanaceous vegetables has not been reported, and only in a research paper of Shandong Agricultural University, it is found that a woven bag of 80 cm * 50 cm is used to carry out tomato cultivation organic substrate test (organic substrate formula is effective for bag culture). Effect of tomato growth and yield[J]. Northwest Agricultural Journal, 2009, 18(3): 184-188)

[0004] The bag cultivation technology in the United States is mainly used in arid and desert areas. Its advantage is that it mainly solves the big problem that the soil in arid desert areas cannot be planted. Disadvantages: 1) The cultivation bags used in cultivation are plastic bags, because plastic bags are breathable and water-permeable 2) The design specifications of the cultivation bag are unreasonable, and 6 tomato plants are planted in a cultivation bag of 100cm×30cm×8cm. Once the diseased plants are found, it is easy to spread each other, and the substrate in the entire cultivation bag will also have The possibility of pathogenic bacteria spreading, so it is more troublesome to deal with

Although the cultivation bag disclosed in the Japanese invention patent (JP2004-329011A) is specially provided with a water seepage device, which solves the problem of water seepage in the cultivation bag, the water and nutrient solution discharged cannot be reused.

resulting in waste and pollution

In addition, the size of the designed cultivation bag is 60cm×40cm, and 4 plants are cultivated in each bag. The above-mentioned problem of disease transmission in the United States due to the large number of cultivation plants in the cultivation bag will also occur.

In addition, the cultivation bag with water seepage function is troublesome to manufacture, and the cost is relatively high, which increases the investment cost
