Culture medium for strawberry water/fertilizer integrated facility culture technology

Abstract

The invention discloses a culture medium for strawberry water / fertilizer integrated facility culture technology. The culture medium comprises a substrate mixture and a strawberry rhizosphere beneficial active microorganism microbial inoculant which accounts for 0.01-0.075% of the culture medium. The substrate mixture is composed of the following components in percentage by volume: 30-45% of rotten broadleaf forest leaf mold, 25-40% of desalted coconut bran, 5-20% of grass carbon, 5-15% of porous material and 1-3% of medical stone. The culture medium has the characteristic of light weight of the raw materials. The compounded culture medium has moderate density, and thus, is beneficial to stereometric shelf facility culture. The materials have clear nutrient contents, thereby being beneficial to accurate application of nutrient elements in the culture process, satisfying the plant growth demands, protecting the environment, and laying the material foundation for strawberry water / fertilizer integrated facility culture. The culture medium preparation technique is simple and convenient to operate, and is suitable for popularization and application.

Description

Technical field [0001] The invention relates to the technical field of plant water and fertilizer integrated facility cultivation, in particular to a cultivation substrate for strawberry water and fertilizer integrated facility cultivation technology. Background technique [0002] Strawberry occupies an important position in fruit production. It is a small berry with high economic value. It is also an important part of urban sightseeing agriculture and suburban picking tourism. Strawberry has high nutritional value, rich in a variety of amino acids, Vc and Vb needed by the human body 1 , Vb 2 , Niacin, phosphorus, zinc, iron, calcium and other mineral elements, known as the "Queen of Fruits". Strawberries can be eaten fresh and processed into jams. They are very popular and are in great demand in the market. At present, strawberry cultivation is mainly based on natural soil cultivation in open and protected areas. The traditional cultivation method is greatly affected by the n...

Problems solved by technology

At present, strawberry cultivation is mostly based on natural soil cultivation models in open fields and protected areas. The traditional cultivation methods are greatly affected by the natural climate, the cost of artificial management and maintenance is high, and the fruit production process is easily polluted by soil and fertilizers. Clean production is required for picking, so the introduction of three-dimensional elevated water and fertilizer integrated cultivation technology into strawberry production has the needs of the times and practical significance

Most of the existing facility cultivation substrates have unclear nutrient content of the substrate materials, which leads to the restriction of integrated water and fertilizer precision fertilization in the later stage and / or the substrate water and fertilizer conservation, poor air permeability, etc., which cannot well guarantee the root temperature during the growth of strawberries. , water, fertilizer, air, pH, and the needs of beneficial microorganisms in the rhizosphere often lead to the occurrence of strawberry root rot, stem rot, and related soil-borne diseases, and a large amount of fertilizer loss not only causes waste but also pollutes surrounding environmental water bodies
