Description
Technical Field
The invention relates to the technical field of soil improvement, in particular to a tea garden acidified soil conditioner, a preparation method thereof and a soil conditioning method.
Background
Tea trees are important economic crops in China, and soil is the foundation for growth of the tea trees. Due to the unreasonable application of chemical fertilizers for a long time and the influence of the cyclic metabolism of substances of tea trees, the tea garden soil is constantly acidified. The acidification of the tea garden soil seriously influences the absorption of the tea trees to nutrients and restricts the growth of the tea trees.
The soil acidification process is that the soil receives H+Then, on the one hand H+The salt-based cations are absorbed on the surface of soil particles through exchange reaction with the salt-based cations on soil colloid, and the exchanged salt-based cations are leached along with the seepage water; on the other hand, H on the surface of the soil grains+And spontaneously reacts with aluminum on the surface of mineral crystal lattice to be rapidly converted into exchangeable Al3+(ii) a The tea garden soil is acidified, clay minerals are changed, the soil base ion saturation (CEC) is reduced, and the soil nutrient holding capacity is reduced. At present, a great deal of documents utilize calcareous materials (lime, dolomite powder and the like) to improve tea garden acidified soil, but the calcareous materials only supplement calcium and magnesium ions lost in the soil, so that the soil pH is improved to a certain extent, the soil is easy to harden, the soil nitrification is promoted, and the nitrogen absorption of tea trees is reduced; in recent years, a great deal of literature adopts biomass charcoal to improve acidified tea garden soil, and a certain effect is achieved in the aspect of improving soil CEC and pH value, but as the mechanism of improving acidified soil by biomass charcoal mainly comprises acid-base neutralization and a certain amount of salt-based ions, the supplemented salt-based ions are easy to lose, and the soil improvement duration is short; the biomass charcoal has low density, the application amount per mu is measured by tons, the application cost is high, and the method only stays in the laboratory stage in the aspect of tea garden acidified soil improvement; meanwhile, after the biomass charcoal is applied, the soil nitrification is greatly promoted, the growth of tea trees with ammonium-nitrogen is influenced, the soil improvement is formed, and the phenomena of no quality improvement and no synergy of the tea leaves are avoided.
Therefore, the problem to be solved by the technical personnel in the field is to invent an effective, low-cost and convenient-to-operate acidified soil conditioner for improving the acidified soil in the tea garden.
