Problems solved by technology

At present, most of the light matrix products on the market use peat as raw material, and peat is a limited natural resource, which is a non-renewable resource. Not only is the market price increasing day by day, but also excessive development will inevitably lead to the depletion of resources.

Embodiment 1

[0021] The matrix is ​​prepared from the following volume fractions of raw materials: 54.5 parts of cow dung, 45 parts of edible fungus residue, and 1.5 parts of fermented bacteria. Among them, the fermented bacterial agent adopts the "Sanju Lishengyuan" microbial fertilizer produced by Fujian Zhangzhou Sanju Biotechnology Co., Ltd. After the raw materials are mixed evenly, they are piled up for 17 days and can be used only after they are fermented and decomposed. The obtained matrix has a particle size of 3.4mm and a bulk density of 0.21g / cm 3 , the pH value is 6.6, the conductivity is 0.26mS / cm, the porosity is 76.3%, and the relative water content is 23.4%.

[0022] Put the prepared light matrix in a nutrition cup (diameter 5cm, height 12cm). After soaking the seeds of peony (variety: Fengdan) for 2 days, sow them in a nutrition cup with light substrate, one seed per cup, and cover with 2~3cm thick light substrate for daily management. Periodic observation, determination...

Embodiment 2

[0024] The matrix is ​​prepared from the following volume fractions of raw materials: 58 parts of cow dung, 43 parts of edible fungus residue, and 1.8 parts of fermented bacteria. Among them, the fermented bacterial agent adopts the "Sanju Lishengyuan" microbial fertilizer produced by Fujian Zhangzhou Sanju Biotechnology Co., Ltd. After the raw materials are mixed evenly, they are piled up for 18 days, and they can be used only after they are fermented and decomposed. The obtained matrix has a particle size of 3.2mm and a bulk density of 0.22g / cm 3 , the pH value is 6.4, the conductivity is 0.24mS / cm, the porosity is 75.7%, and the relative water content is 24.1%.

[0025] Peony seed seedling cultivation is the same as in Example 1, and the peony germination rate and growth index measurement results are shown in Table 1.

Embodiment 3

[0027] The substrate is prepared from the following volume fractions of raw materials: 60 parts of cow dung, 50 parts of edible fungus residue, and 2 parts of fermented bacteria. Among them, the fermented bacterial agent adopts the "Sanju Lishengyuan" microbial fertilizer produced by Fujian Zhangzhou Sanju Biotechnology Co., Ltd. After the raw materials are mixed evenly, they are piled up for 18 days, and they can be used only after they are fermented and decomposed. The obtained matrix has a particle size of 3.6mm and a bulk density of 0.20g / cm 3 , the pH value is 6.2, the conductivity is 0.30mS / cm, the porosity is 75.5%, and the relative water content is 23.5%.

[0028] Peony seed seedling cultivation is the same as in Example 1, and the peony germination rate and growth index measurement results are shown in Table 1.

Abstract

The invention relates to a seedling-raising light medium. The seedling-raising light medium is prepared by fermenting 50-60 parts of cattle manure and 40-50 parts of edible fungus residue through 1-2 parts of fermentation inoculum. The light medium is favorable in particle size composition, is excellent in porosity, is free of live pathogenic bacteria, ova and harmful substances, is favorable in nutrition, and achieves a good seedling raising effect when being used for peonies. Compared with traditional soil-based seedling raising, the light medium provided by the invention realizes earlier and fuller emergence of stronger seedlings, achieves a better root system conglomeration effect, and has a higher seedling transplanting survival rate. Besides, the seedling-raising light medium is prepared directly through fermentation of 17-18 days without performing separated dry and wet treatment on the raw material cattle manure, thereby effectively simplifying the production step, and greatly saving the labor cost and the time cost.

Description

technical field [0001] The invention relates to a light substrate for seedling cultivation, in particular to a light substrate for seedling cultivation using cow dung and edible fungus residue as raw materials. Background technique [0002] With the rapid development of modern agriculture and forestry, urban wall greening, and the popularization and application of soilless seedling technology, people's demand for seedling substrate is increasing. Light substrate is a mixture of agricultural and forestry wastes that have undergone natural fermentation or carbonization treatment and light minerals such as peat, perlite, and vermiculite. It is beneficial to the growth of seedlings, and has been widely used in agricultural seedling production, forest container seedling cultivation and other industries. At present, most of the light matrix products on the market use peat as raw material, and peat is a limited natural resource and a non-renewable resource. Not only is the market ...
