Preparation method for soilless seedling growing substrate of cucumbers based on auricularia polytricha mushroom dregs

Abstract

The invention relates to a preparation method for a soilless seedling growing substrate of cucumbers based on auricularia polytricha mushroom dregs. The method strictly controls fermentation of auricularia polytricha mushroom dregs, the auricularia polytricha mushroom dregs are prevented from generating reductive toxic substances of a large number of aldehydes, a large amount of hydrogen sulfide,ethyl alcohol and the like, and the water binding capacity of the mushroom dregs is greatly improved; the mushroom dregs replace part of turfy soil and are mixed with perlite, the soilless seedling growing substrate of cucumbers is prepared, the substrate is used for cultivating cucumbers, and growth indexes of height of stems of cucumber plants and length and thickness of petioles and indexes ofyield, quality and the like are significantly increased. Production cost is effectively reduced, large-scale soilless seedling growing of the cucumbers is achieved, reusing of agricultural wastes of the auricularia polytricha mushroom dregs is achieved, and agricultural sustainable development is achieved. Better social benefits, economic benefits and ecological benefits are achieved.

Description

technical field [0001] The invention relates to a method for preparing a soilless seedling-raising substrate of cucumber based on fungus slag, and belongs to the technical field of soilless seedling raising in agriculture. Background technique [0002] Cucumber (Cucumis sativus L.) belongs to the subgenus Cucumis (Subgen. Cucumis), the genus Cucumis (Cucumis. L), and the family Cucurbitaceae (Cuvurbitaceae). According to geographical distribution and ecological characteristics, it can be divided into South China type, North China type, European greenhouse type, European and American open field type, processing type and wild type. China's cucumber production has a history of more than 2,000 years. It occupies a very important position in my country's vegetable production and consumption. It also has positive significance in the adjustment of agricultural industrial structure and the realization of agricultural industrialization. Due to serious obstacles in continuous croppin...

Problems solved by technology

With the expansion of fungus, Yutai, the largest town of fungus in Shandong, produces 15,000 to 24,000 tons of dried fungus residue every year. If it cannot be used in a timely and effective manner, it will not only become a breeding source for pests and bacteria, but also seriously affect the next season. Edible fungus production, but also damage to the environment

[0006] If the Auricularia edulis slag is used comprehensively to cultivate cucumbers, the cost can be greatly reduced. However, the slag of Auricularia edulis must be fermented before it can be used. Inhibition of root respiration of cucumber seedlings caused by too low oxygen content in the roots of cucumber seedlings. In addition, improper fermentation of Auricularia spp. residues will also produce a large amount of reducing toxic substances such as aldehydes, hydrogen sulfide, and ethanol, which will cause damage to the roots of plants.
