Abstract

The invention provides a soil conditioner containing potassium bacteria and a preparation method of the soil conditioner. The soil conditioner contains the potassium bacteria which can convert solidified ineffective potassium in the soil into quick-acting potassium, so that the problem that crops lack potassium is solved, and damage to environment due to use of chemical fertilizer is reduced; meanwhile, a fermentation method different from tradition methods is adopted, radix astragali powder and hydrogen peroxide are added during fermentation and can stimulate the potassium bacteria to produce spores and enhancing the vitality of the potassium bacteria, thus, the viable count and the spore formation rate of the potassium bacteria are increased, and the activity and efficiency of the soil conditioner are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of soil improvers, and in particular relates to a soil improver containing potassium-dissolving bacteria and a preparation method thereof. Background technique [0002] Potassium is involved in plant cell osmotic adjustment, material transport, nitrogen utilization, protein and sugar synthesis, and enhancement of plant photosynthesis, so potassium plays a very important role in plant growth and development. Potassium in the soil, 90% of which is in the form of silicate minerals such as potassium feldspar and mica, these potassium elements can only be absorbed and utilized by plants when they are released from the minerals, which leads to soils rich in potassium Potassium deficiency phenomenon. Affected by various factors such as crop absorption, loss, and corrosion, the content of available potassium in the soil has been greatly reduced. Soil potassium deficiency and potassium fertilizer shortage have becom...
