Compound slow release fertilizer used for culturing needle mushroom

Abstract

The invention relates to the technical field of agricultural fertilizer, and particularly relates to a compound slow release fertilizer used for culturing needle mushroom. The compound slow release fertilizer used for culturing needle mushroom is prepared from the following materials in parts by weight: 60-80 parts of rice bran, 30-50 parts of saw dust, 15-30 parts of eggshell, 5-25 parts of fruitpeel, 5-20 parts of bean pulp, 5-25 parts of seaweed, 3-12 parts of chitosan, 5-15 parts of starch, 6-15 parts of nut shell, 5-25 parts of animal waste, 1-5 parts of diammonium hydrogen phosphate, 1-5 parts of selenium ore, 0.33-1.33 parts of inorganic mineral salt, 0.1-0.3 part of calcium sulfate, and 3-10 parts of a microorganism leavening agent. The compound slow release fertilizer used for culturing needle mushroom has extremely strong adsorbability and water retentivity, is good in slow release effect and high in fertilizer nutrient utilization rate, increases the yield and nutritive value of edible fungi, and increases the income.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a compound slow-release fertilizer for cultivating Flammulina velutipes. Background technique [0002] The scientific name of Flammulina velutipes is Chrysanthemum velutipes, also known as Flammulina velutipes, Pleurotus ostreatus, Frozen mushrooms, Flammulina velutipes, etc. Because of its slender stipe, it looks like golden needles, so it is called Flammulina velutipes, which belongs to the family Agaricaceae. The genus is a fungal lichen. Flammulina velutipes is rich in nutrition, fleshy and unique in flavor. Flammulina velutipes contains protein, carbohydrates, vitamins, trace elements, minerals and various amino acids needed by the human body. Eating more can increase human immunity. At present, the market demand is very large, and the production scale is constantly expanding, but there are many problems in the planting process of Flammulina velutipes, the most impor...

Problems solved by technology

[0003] Currently used fertilizer formulas for supplementing the cultivation of Flammulina velutipes 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 material contains bacteria such as carbon, nitrogen, phosphorus, and potassium A large number of elements and some trace elements required for silk growth, but it takes a period of time (5-7 days) after the strain is sown to be released and used by mycelium growth, and some nutrients are insufficient, so the mycelium is obviously inhibited The early growth of mycelia makes the early growth of mycelium 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 nutrient supply is insufficient and the yield decreases. Therefore, it is necessary to apply nutrient fertilizers to the compost.

[0004] Slow-release fertilizers, also known as long-acting fertilizers, mainly refer to fertilizers that transform into effective nutrients for plants after being applied to the soil at a slower rate than ordinary fertilizers, so that the release rate is consistent with the law of crops absorbing nutrients, which greatly improves the fertilizer efficiency. utilization rate, but there is no slow-release fertilizer for the growth of mushrooms
