Composite fertilizer for soilless cultivation of edible mushrooms

Abstract

The invention relates to the technical field of agricultural fertilizers, in particular to a composite fertilizer for soilless cultivation of edible mushrooms. The composite fertilizer for the soilless cultivation of the edible mushrooms is prepared from the following materials in parts by weight: 60 to 80 parts of rice bran, 30 to 50 parts of wood chip, 15 to 30 parts of sesame stalk, 5 to 25 parts of fruit peel, 5 to 20 parts of black bean meal, 3 to 12 parts of algae, 6 to 15 parts of nutshell, 5 to 25 parts of animal excrement, 1 to 5 parts of diammonium hydrogen phosphate, 1 to 5 parts ofselenium ore, 0.2 to 0.8 part of stannite, 0.02 to 0.1 part of zinc salt, 0.08 to 0.2 part of magnesium salt, 0.01 to 0.1 part of manganese salt, 0.05 to 0.3 part of iron salt, and 3 to 10 parts of microbial fermenting agent. The composite fertilizer for the soilless cultivation of the edible mushrooms has the characteristics that the slow release effect is good, and the fertilizer utilization rate is high; the growth and development of the edible mushrooms are promoted, and the nutritional value of the edible mushroom is increased.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a compound fertilizer for soilless cultivation of edible fungi. Background technique [0002] Edible fungi are rich in nutrition, fleshy and unique in flavor. Edible fungi contain protein, carbohydrates, vitamins, trace elements, minerals and various amino acids needed by the human body. Eating more can increase human immunity. Common edible fungi include shiitake mushrooms , straw mushrooms, mushrooms, fungus, white fungus, Hericium erinaceus, bamboo fungus, matsutake (matsutake), Tricholoma edodes, russula and boletus, etc. At present, the market demand is very large, and the production scale continues to expand, but there are many problems in the cultivation process of edible fungi, the most important of which are the low yield and poor efficiency. This requires adding compound fertilizers to the cultivation material to improve Its nutritional value and economic benefi...

Problems solved by technology

[0003] The currently used fertilizer formulations for supplementing edible fungus cultivation nutrition mainly focus on nutrients such as nitrogen, phosphorus, calcium, and sulfur, while ignoring the supply of other necessary nutrients and trace elements; although the cultivation materials contain carbon, nitrogen, phosphorus, potassium, etc. The large amount of elements and some trace elements required for the growth of the mycelia, but it takes a period of time (5-7 days) after the strains are sown, to be released and used by the growth of the mycelium, and some nutrients are insufficient, so the bacteria are obviously inhibited. The early growth of silk makes the early growth of mycelia slow, and it is easy to be infected by miscellaneous bacteria, resulting in cultivation failure or slow growth of bacteria and slow fruiting. In the late growth period, the supply of nutrients is insufficient and the yield decreases. Therefore, nutrients must be applied to the compost fertilizer
