preparation example Construction

[0023] The present invention also provides a kind of vermicompost nursery substrate preparation method, comprises the following steps:

[0024] Step 1: Processing earthworm feed made from straw and cow dung;

[0025] During specific implementation, the stalks are crushed into particles with a length of 5-8mm, and the cut stalks are evenly stirred with cow dung at a mass ratio of 1:9 to make earthworm feed.

[0026] Step 2: feeding earthworms with the earthworm feed made in step 1 to prepare high-quality vermicompost;

[0027] During specific implementation, earthworms were fed with earthworm feed for 1.5-2 months, until the stench and peculiar smell of cow dung disappeared, and good vermicompost was produced at this moment.

[0028] Step 3: After separating the earthworms from the vermicompost, they are utilized separately;

[0029] Step 4: 50%-60% of vermicompost, 10%-30% of biochar, 10%-20% of phosphogypsum, and 10%-20% of vermiculite are mixed according to mass percentage...

Embodiment 1

[0033] The straw is crushed into particles with a length of 5-8mm, and the cut straw is mixed with cow dung at a mass ratio of 1:9 to make earthworm feed. The earthworms were fed with the earthworm feed for 2 months, and the stench and peculiar smell of cow dung disappeared, and good vermicompost was produced at this time. After the earthworms are separated from the vermicompost, 50% of the vermicompost, 25% of biochar, 15% of phosphogypsum and 10% of vermiculite are mixed according to the mass percentage to make a seedling raising substrate. The existing seedling-raising substrate purchased in the market was used as a control group to compare with the seedling-raising substrate of this embodiment.

[0034] Apply the prepared seedling substrate to the eggplant, and cover it with a 50-hole seedling tray. Sow 1 seed per hole after watering, and observe the emergence of seedlings after 5 days of seedling cultivation. The emergence rate of cow dung and vermicompost seedling raisi...

Embodiment 2

[0037] The straw is crushed into particles with a length of 5-8mm, and the cut straw is mixed with cow dung at a mass ratio of 1:9 to make earthworm feed. The earthworms were fed with the earthworm feed for 2 months, and the stench and peculiar smell of cow dung disappeared, and good vermicompost was produced at this time. After the earthworms are separated from the vermicompost, 45% of the vermicompost, 30% of the biochar, 15% of the phosphogypsum and 10% of the vermicompost are mixed according to the mass percentage to make a seedling raising substrate. The existing seedling-raising substrate purchased in the market was used as a control group to compare with the seedling-raising substrate of this embodiment.

[0038] Apply the prepared seedling substrate to the pakchoi, and use a 72-hole seedling tray to cover it. After watering, one seed per hole was sown, and the emergence of seedlings was observed after 5 days of seedling cultivation. The emergence rate of seedlings rai...

Abstract

The invention provides an earthworm cast seedling breeding medium. The medium is prepared from, by mass, 50-60% of earthworm cast, 10-30% of biological charcoal, 10-20% of ardealite and 10-20% of vermiculite. The earthworm cast is defecated by earthworms after the earthworms eat and digest earthworm feed prepared from straw and cow dung. The earthworm cast serves as the main material, straw, cow dung, biological charcoal and ardealite are all recycled wastes, waste is turned into wealth, the atmosphere pollution problem caused by straw combustion and the environment pollution problem caused bycow dung and the like are solved, economic benefits are increased, and meanwhile large ecological benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a vermicompost seedling raising substrate and a preparation method thereof. Background technique [0002] At present, seedlings mostly use a compound simple matrix of non-renewable and non-degradable materials such as peat and cotton rock. On the one hand, due to the lack of clear matrix parameter standards in production, the physical and chemical properties of the seedling matrix are poor, and the nutritional components are lacking, resulting in a low survival rate for seedlings. On the other hand, non-renewable and non-degradable materials such as peat and cotton rock have the problems of resource depletion and environmental pollution. Therefore, it is imminent to study a seedling substrate with excellent physical and chemical properties. Contents of the invention [0003] The embodiments of the present invention provide a vermicompost seedling-raising substr...
