What are the advantages of soilless culture?

Soilless culture has the following advantages:

(1) Soilless culture does not use natural soil, organic fertilizer, no odor, no mosquitoes and flies, no soil-borne diseases, no underground pests and a clean production environment.

(2) The output is high and the product quality is high, so the economic benefit is also high.

(3) Save labor, time and effort, change stubble quickly, and do not need to dig holes, prepare soil, cultivate soil and weed. There is no slow seedling stage after planting, and it grows fast.

(4) Soilless culture substrate has good air permeability, which is conducive to raising the substrate temperature, good water and fertilizer conservation, adequate nutrition, stable and appropriate pH value, and is conducive to the growth and development of roots.

(5) The scale production of soilless culture is convenient for mechanized operation, factory production and automatic control, which can reduce physical labor.

(6) Three-dimensional cultivation can be carried out to improve the land utilization rate.

(7) It is convenient to replace the substrate, and it is also convenient to disinfect the substrate, which is beneficial to the prevention and control of pests and diseases.

(8) It can be used for greening roofs and bungalow platforms, balconies of buildings and indoors; The construction of urban hanging gardens or vegetable gardens can increase the cultivated land area, adjust the urban microclimate, improve the urban air quality and be beneficial to environmental protection.

(10) can save water.

(1 1) can be used in spacecraft, aircraft carriers, ocean-going ships, isolated military bases, outposts and other military fields to produce high-quality vegetables.
