[Development of a minerals supply system for plants in a conveyor-type space greenhouse].
The paper presents ideas of optimizing the mineral nutrition system for salad crops in a space greenhouse. Experiments showed that to use mineral-saturated fiber ionite BIONA-V3 as an artificial soil will require to upmass a lot of expandable materials because of low specific content of nutrients. An additionally mineralized fiber soil makes possible to reduce mass of ionite in 5.6 times and volume in 28 times. The proposed mineral supply system is composed of two enrichment catridges with granulated ionite BIONA-V3 and slow-releasing fertilizer Osmocote 114-14-4, and a controller of irrigation water electric conduction stabilizer. Tests showed that this system provides sufficient mineral nutrition to plants and can be recommended for in-flight testing.
