Problems solved by technology

[0003] However, the cultivation matrix made of such ultrafine glass fibers has limited strength and shape stability, and is prone to compression and porosity reduction after repeated use, thereby reducing its water retention performance; in addition, the ultrafine glass fibers The water or nutrient solution in the glass fiber does not have long-term retention performance, and it is easy to diffuse and evaporate into the atmosphere and lose some; again, the pore

Abstract

The invention relates to stock growing soil and a preparation method thereof and belongs to the technical field of soilless culture. A stock growing medium is composed of flexible and hydrophilic hollow fibers with mass fraction more than 80% and other matters, and porosity is more than 85%; the diameter of the hollow fibers is 30-100 micrometers, and the length of the hollow fibers is 0.5-10mm; volume ratio, accounting for the total volume, of the hollow part of the hollow fibers is 0.5-0.85; the other matters at least contain water insoluble organic adhesive, soil and an antibacterial agent. The stock growing medium provided by the invention is light in weight and durable and has relatively high water retention capacity and lasting water and nutrient retention capacity, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to seedling cultivation soil and a preparation method thereof. Background technique [0002] Soilless cultivation usually uses light materials such as peat or forest leaf humus and expanded vermiculite as the cultivation substrate to fix the plants, so that the plant roots directly contact the nutrient solution, and adopts the modern seedling raising technology of mechanized precision sowing for one-time seedling formation; for the cultivation substrate In general, water retention and air permeability are very important. A large water retention means that a large amount of nutrient solution can be retained with a small volume of cultivation substrate, and the time period for reapplying the nutrient solution is longer, which also saves volume; For this reason, the Chinese invention patent with the authorized notification number CN1020326C discloses a soilless cultivation...
