Strawberry culture medium and application thereof

Abstract

The invention relates to the technical field of plant cultivation, and particularly discloses a strawberry cultivation medium and application thereof. The strawberry cultivation medium comprises volcanic rock, peat soil and akadama soil, wherein the mass ratio of the volcanic rock to the peat soil to the akadama soil is (7-9): (5-7): (2-4); and the volcanic rock, the peat soil and the akadama soilaccount for 80%-90% of the mass of the culture medium. The culture medium disclosed by the invention can increase the retention capacity and utilization efficiency of moisture, fertilizer and nutrient substances and efficiently exert the productivity of the medium, so that the obtained strawberry is high in yield and good in quality. And the substrate is not easy to decompose and crush, has smallannual change of physicochemical properties, can be repeatedly used, and is beneficial to saving labor and cost.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a strawberry cultivation substrate and its application. Background technique [0002] At present, more and more elevated soilless substrate cultivation methods are used in strawberry production. Conventional substrates include peat perlite compound substrate, coconut peat or rock wool, etc. Later, due to the decomposition and fragmentation of the substrate, the air permeability and water permeability of the substrate will be seriously reduced. Although it can be reused, the use effect is poor, which affects the production of strawberries, while other cultivation substrates are generally disposable. It needs to be replaced once, especially for elevated cultivation, which is more labor-intensive and time-consuming, and the cost of waste disposal is very high, which may pollute the environment.

Problems solved by technology

[0002] At present, more and more elevated soilless substrate cultivation methods are used in strawberry production. Conventional substrates include peat perlite compound substrate, coconut peat or rock wool, etc. Later, due to the decomposition and fragmentation of the substrate, the air permeability and water permeability of the substrate will be seriously reduced. Although it can be reused, the use effect is poor, which affects the production of strawberries, while other cultivation substrates are generally disposable. Replace it once, especially for elevated cultivation, it is more labor-intensive and time-consuming, and the cost of waste disposal is very high, which may pollute the environment

[0003] In addition, in the Chinese patent application CN106962155, although a soilless cultivation substrate prepared by using non-metallic minerals is disclosed, it includes: expanded perlite, zeolite, bentonite, and vermiculite, which can be reused, but according to its composition, its composition According to physical and chemical properties, the original nutrient content is very small, it is not easy for strawberries to colonize and survive, and it lacks water and fertilizer retention ingredients, which is not conducive to improving the yield and quality of strawberries; in addition, because zeolite is hard and does not absorb water, the bulk density is quite different from other ingredients, and it is separated when used. More serious, after one or more crops of use, the physical and chemical properties such as porosity and water holding capacity will change seriously, and the components of the matrix will also be unevenly distributed, making it impossible to reuse for a long time

[0004] When planting strawberries, because the roots of strawberries are not resistant to waterlogging, it is required that the planting substrate not only needs to be breathable and permeable, but also needs to have a certain degree of water and fertilizer retention, and it is best to have a certain amount of original nutrients. Due to the large differences in the physical and chemical properties of different matrix materials during compounding, if you want to take into account all aspects of demand after mixing, you often encounter too high or too low original nutrient content, too high or too low porosity, and the matrix is ​​easily broken during the production process. Therefore, it is not easy to obtain reusable and comprehensive physical and chemical properties to meet the high-quality and high-yield requirements of strawberries, which restricts the development of high-efficiency substrates in the field of strawberry cultivation.
