Let soilless cultivation management become "fools"
People who like flowers and grass can be happy with farmers and uncles. A new soilless culture technology can reduce the cost of fertilizers for soilless cultivation of nutrient solutions. This is the organic ecological soilless culture technology invented by Jiang Weijie and other researchers of the Chinese Academy of Agricultural Sciences. In an interview, the reporter learned that this soilless culture technology first uses a variety of organic resources, including crop straws and various feces, to replace the expensive old-fashioned peat as a substrate for soilless cultivation, while adopting organic fertilizer as the mainstay. Formula fertilization technology. This fertilization technology can make the total fertilization less than 70% of the soil cultivation, while the one-time investment is also 50% lower than the well-known nutrient solution without soil, and the fertilizer cost is 50%~600% lower than the nutrient solution without soil cultivation. %. It is said that this new soilless cultivation technology can use as little or no chemical fertilizer as possible. It makes the utilization rate of water increase, but the amount of use is greatly reduced; it can ensure that more than 90% of the irrigation water is used by plants, and the water saving is 50%~70% higher than that of ordinary soil. It is understood that the introduction of organic agriculture into soilless cultivation not only improves the quality of agricultural products, but also simplifies the tedious procedures of previous soilless cultivation, realizes the “foolization†of soilless cultivation management, and at the same time creates greater social benefits and ecology. benefit.
