Soilless growing tomatoes in the greenhouse
Soilless culture technology has developed rapidly in the agricultural field in recent years, so why do we develop soilless culture technology? What are the advantages of soilless cultivation?
Good quality agricultural products:The soilless cultivation in greenhouse can reasonably adjust the environmental conditions such as light, temperature, water, air and fertilizer for crop growth, and give full play to the production potential of crops. Compared with soil cultivation, the growth rate of soilless cultivation was faster.
Save resource:Soilless culture can avoid the loss and leakage of soil irrigation water and nutrients and the absorption and fixation of soil microorganisms, which can be fully absorbed and utilized by crops and improve greenhouse utilization efficiency.
The water consumption of soilless cultivation is only about 10% to 25% of soil cultivation, saving water resources, especially for crop cultivation in dry and water-scarce areas has its important significance, is one of the effective measures to develop water-saving agriculture. The fertilizer utilization rate of soil cultivation is only about 50%, or even as low as 20% to 30%, while the fertilizer utilization rate of soilless cultivation is as high as more than 90%. Soilless cultivation saves heavy manual labor such as plowing, ploughing, carding, weeding, etc., and with the use of computers and systems in soilless cultivation production management facilities, mechanization and automatic operation are gradually realized, which greatly reduces labor intensity, saves labor force, improves labor productivity, and can be adopted in a similar way to industrial production.
Reduce pests and diseases:Soilless cultivation in greenhouse avoid the invasion of external and soil pathogens and pests on the crop, coupled with robust crop growth, so the occurrence of diseases and pests is slight, but also easier to control. There is no soil planting species of parasite eggs and heavy metals, chemical harmful substances and other public pollution.
