Cultivation substrate used for ex-situ transplantation of alpine rose old tree stumps

Abstract

The invention provides a special cultivation substrate and an application method for solving the problems that root system recovering and reestablishment are difficult after ex-situ transplantation of alpine rose old tree stumps. The method comprises the preparation steps of A, self preparing leaf mold, wherein wood bits are added in collected dead leaves, the ratio of the wood bits to the collected dead leaves is 1:5, the mixture of the collected dead leaves and the wood bits are smashed, water is added in the mixture of the collected dead leaves and the wood bits to drench the mixture of the collected dead leaves and the wood bits, the mixture of the collected dead leaves and the wood bits are buried in the soil for one year and are sufficiently decomposed, and the leaf mold is prepared; B, using turfy soil, the self-prepared leaf mold and pine needles according to the volume ratio of 7:2:1 for preparing substrate raw materials; C, preparing mixed base fertilizers, wherein three kinds of controlled-release fertilizers with the ratios of N to P to K being 10:11:18, 15:9:11, and 9:14:19 respectively are selected, and the three kinds of release fertilizers are evenly mixed in the proportion of 1.5: 1: 2; D, evenly mixing the substrate raw materials, and then adding the prepared 1 kg/m<3> of base fertilizers in the mixed substrate raw materials; E, conducting water purification process; F, using the water processed in the step E for wetting the substrate, and evenly stirring the substrate again, wherein the substrate materials are held into a spherical shape by hands and immediately loosen if the hands let the substrates go, the proper moisture content is 80-90 %, and the standards of loosening, ventilation and water retention are met.

Description

technical field [0001] The invention relates to a substrate for plant cultivation, in particular to a cultivation substrate for ex situ transplantation of alpine rhododendron ancient tree stumps and an application method thereof. Background technique [0002] Rhododendron is the most valuable ornamental flower in the world. It is called "the beauty of flowers" and is listed as one of China's top ten famous flowers. Alpine Rhododendron is a fine product in the Rhododendron family, with extremely high ornamental and economic value. In the wild distribution area of ​​Alpine Rhododendron, the root systems of many wild alpine Rhododendron stumps have been damaged to varying degrees due to various reasons such as climate, geography, or man-made reasons. The habitat is suitable for continued growth, or because of the age of the trees or the important geographical location, it is usually necessary to adopt the protection method of in situ treatment; in addition, some alpine Rhodode...
