Embodiment 1

[0035] Embodiment 1: a kind of seedling-raising substrate, each component and parts by weight in the raw material are as shown in table 1, and wherein nutrient contains trace element selenium, phosphorus, potassium, magnesium, zinc, and wherein microbial bacterial agent comprises indole acetic acid, cell Mitogen, SOD enzyme and gibberellin GA4.

[0036] A kind of preparation method of seedling raising matrix comprises the following steps:

[0037] Step 1, mix nutrients, microbial agents, brassinosteroids and polyoxyethylene polyoxypropylene block copolymers with water and stir evenly to obtain a mixed solution, put vermiculite into the mixture to fully absorb the mixed solution, and obtain a spare mixture;

[0038] Step 2, fully mixing peat, coconut peat, and perlite through a mixer to obtain a semi-finished matrix;

[0039] In step 3, the spare mixture is added into the blender and the substrate semi-finished product is continuously stirred, and the seedling cultivation sub...

Embodiment 2

[0041] Embodiment 2: a kind of seedling-raising substrate, the difference from embodiment 1 is that each component and weight parts in the raw materials are as shown in table 1.

[0042]Among them, the growth rate of the seedlings is tested by the following method. Take 20 passion fruit seedlings with a height difference of ±0.3cm, and record the height of each seedling. In the greenhouse at ℃, corresponding plant growth lamps are equipped above each column of seedlings, and the staff waters each column of seedlings regularly and quantitatively, and re-measures the height of each seedling after one week, removes the maximum and minimum values, and obtains Average growth height of seedlings. Among them, the average growth height of seedlings is shown in Table 1.

Embodiment 3

[0043] Embodiment 3: A seedling-raising substrate, the difference from Embodiment 1 is that the components and parts by weight in the raw materials are as shown in Table 1.

[0044] Among them, the growth rate of the seedlings is tested by the following method. Take 20 passion fruit seedlings with a height difference of ±0.3cm, and record the height of each seedling. In the greenhouse at ℃, corresponding plant growth lamps are equipped above each column of seedlings, and the staff waters each column of seedlings regularly and quantitatively, and re-measures the height of each seedling after one week, removes the maximum and minimum values, and obtains Average growth height of seedlings. Among them, the average growth height of seedlings is shown in Table 1.

Abstract

The invention discloses a seedling-growing substrate and a preparation method thereof. According to parts by weight, the material is prepared from the following components: 200 to 300 parts of peat; 30 to 80 parts of coconut shell powder; 20 to 70 parts of vermiculite; 60 to 120 parts of perlite; 5 to 10 parts of nutrition agent; 10 to 15 parts of microbial agent; and 4 to 8 parts of brassinolide;and the microbial agent is prepared from heteroauxin. Both brassinolide and heteroauxin can induce plant growth gene expression, having the effect of promoting the growth of plants, brassinolide canregulate the polar transport of heteroauxin, having the effect of synergistic promotion, and thereby the growth speed of plants is increased. The coconut shell powder is coconut shell powder fiber powder, and is a purely natural organic medium which comes off in the process of processing coconut shells at a limited position, and the processed coconut shell powder is highly suitable for growing plants, and has high air permeability. With an adsorbing effect and high water-retaining capability, the vermiculite can adsorb nutrient substances and the microbial agent, preventing the loss of the nutrient substances and the microbial agent, and thereby the requirement of plants on nutrition is met.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, and more specifically relates to a seedling raising substrate and a preparation method thereof. Background technique [0002] In the nursery base, in order to improve the survival rate of seedlings and the speed of seedling growth, the nursery base will provide appropriate seedling substrates for seedlings. [0003] Notification number is that the Chinese patent of CN100441090C discloses a kind of melon vegetable seedling raising substrate, and this seedling raising substrate is that following raw material is compounded by weight ratio: fermented cow dung 50-60%; Peat 15-20%; Vermiculite 10- 15%; perlite 10-15%; NPK compound fertilizer 0.2%. [0004] This kind of seedling-raising substrate mainly uses nitrogen, phosphorus and potassium compound fertilizer as nutrient substance, which has a low effect on promoting the growth of plants and a slow growth rate, which needs to be improved. ...
