Dust-free plant cultivation soil with uniform nutrients

Abstract

The invention relates to plant cultivation soil, in particular to dust-free plant cultivation soil with uniform nutrients. The cultivation soil is prepared according to a ratio and comprises, by weight, volcanic rock with the particle size of 0.5-0.8 cm, green zeolite with the particle size of 0.5-0.7cm and medical stone with the particle size of 0.2-0.7 cm; the volcanic rock, the green zeolite and the medical stone are uniformly distributed to constitute the soil. According to the cultivation soil, the volcanic rock, the green zeolite and the medical stone which have large particle size are mainly selected and screened out, granular soil with the diameter of 0.5-0.8 cm is selected, and amendments such as red jade soil, pumice stone, volcanic pumice, pelelith, Luzao soil and volcanic sandare used in extremely special cases for adjusting the density of the granular soil, so that the purpose of making rooting of pulp is achieved. After powdering contrast, the water permeability is higher, rotted roots caused by anaerobic respiration of the roots are avoided, and meanwhile, dust-free cultivation of plants on the basis of the soil is achieved.

Description

technical field [0001] The invention relates to a plant cultivation soil, in particular to a dust-free plant cultivation soil with uniform nutrition. Background technique [0002] Soil improvement is nothing more than physical, chemical and biological methods. These methods can be divided into two types: one is landfilling and covering new soil, and replacing it with new soil is a common method; The roots cause trauma and are prone to mildew and anaerobic respiration causing rot, causing irreparable damage to plants, and it is very troublesome to stack or dispose of the replaced soil. There is also a kind of rinsing and soilless cultivation methods. These methods are conventional measures in plant cultivation. Nutrient elements are also one of the indispensable factors in the soil-plant system, such as potassium hydrogen phosphate, potassium dihydrogen phosphate, ammonium phosphate and other fertilizers. If the concentration is broken within a certain interval, the plant ce...

Problems solved by technology

However, it is not enough to only use large-grained soil. For example, the selection of granular soil with insufficient soil hardness is easy to pulverize. After pulverization, the accumulation will cause the soil density of the plant roots to increase significantly, and the air permeability conditions will deteriorate, resulting in anaerobic respiration of the plant roots and causing corruption.

The granular soil pulverized by the experiment will pulverize over time and form a network-like sponge-like structure at the roots, and the water permeability will be greatly reduced. Over time, the plants will suffer from water shortage and eventually die.
