Problems solved by technology

However, the kale planted in the general greenhouse is mainly used to harvest its small plants. The existing soilless culture substrates are not mainly adjusted for the kale, which is likely to cause the loss of nutrient solution or poor fixation effect of the kale.

Embodiment 1

[0025] This embodiment discloses a culture substrate of vermiculite powder for soilless cultivation of amaranth, which comprises 25-40 parts of rice straw granules, 90-100 parts of vermiculite powder, 130-145 parts of humus and 35-48 parts of water retaining agent in parts by weight. Parts, the following is the specific preparation method of the matrix:

[0026] First prepare to take straw crumbs, vermiculite powder, humus and water retaining agent, and then place them separately for treatment.

[0027] Among them, the specific method of preparing vermiculite powder is: select raw vermiculite flake raw material and put it into an open porcelain crucible, put it into a heating furnace with an iron plate as a carrier, heat it at 980-1100°C for 1.5h, and then cut off the power Cooling; add 25% tributyl phosphate and isopropanol mixture to the cooled expanded vermiculite and stir, then filter and wash with distilled water, and put it into the dryer again to dry at 120-130°C for 2-...

Embodiment 2

[0031] According to the preparation method of Example 1, this example provides a culture substrate for soilless culture of amaranth with vermiculite powder, 25 parts by weight of rice straw granules, 95 parts of vermiculite powder, 145 parts of humus and 40 parts of water-retaining agent , and then prepare an experimental group 1 for comparative testing, wherein the experimental group 1 includes 20 groups of test samples with the same amount.

Embodiment 3

[0033] According to the preparation method of Example 1, this example provides a culture substrate for soilless culture of amaranth with vermiculite powder, 25 parts by weight of rice straw granules, 55 parts of vermiculite powder, 145 parts of humus and 45 parts of water-retaining agent , and then prepare an experimental group 2 for comparative testing, wherein the experimental group 2 includes 20 groups of test samples of the same amount.

Abstract

The invention discloses a preparing method for a culture medium for edible amaranth soilless-culture with vermiculite powder. The preparing method includes the following steps that 25-40 parts by weight of straw particles, 90-100 parts by weight of vermiculite powder, 130-145 parts by weight of humus and 35-48 parts by weight of water-retaining agent are weighed, and then are placed respectively to be treated; the straw particles and the vermiculite powder are put into a drying oven and subjected to vacuum drying for 2 h at the temperature of 75 DEG C; the dried vermiculite powder and the dried straw particles are mixed and put into a vibrating ball mill and are vibrated, mixed and ground to obtain mixed powder A; the ground mixed powder A is poured into a powder mixing machine, then the prepared humus and the prepared water-retaining agent are added into the powder mixing machine, mixed fertilizer is added into the mixed powder A, then the mixture is fully fixed for 2 h to 3 h, and afinished product is finally obtained and detected. According to the preparing method, the multiple components are orderly added and mixed with the suitable method, and through a series of treatment, the whole medium can have the good fertilizer efficiency and the good water-retaining effect.

Description

technical field [0001] The invention belongs to the field of soilless cultivation substrates, and in particular relates to a preparation method of a vermiculite powder soilless cultivation substrate for amaranth. Background technique [0002] Soilless cultivation uses light materials such as peat or forest leaf humus and expanded vermiculite as the seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts the modern seedling technology of mechanized precision seeding for one-time seedling formation. The selected seedling tray is divided into compartments, sow one seed in one compartment, and one plant in one room for seedlings. The root system of the seedlings and the substrate are intertwined with each other. nursery. Substrate cultivation is a method with the largest promotion area in soilless cultivation. It fixes the root system of the crop in an organic or inorganic substrate, and supplies the crop nutrient so...
