Embodiment 1

[0072] Embodiment 1 Seedling raising substrate and preparation method thereof

[0073] The present embodiment provides a taro selenium-enriched organic seedling-growing substrate, which is made from the main ingredients and auxiliary materials of the following mass ratios:

[0074] The ratio of the main material to the auxiliary material is 7:3, the main material is 70% Pleurotus eryngii residue, and the auxiliary material is composed of 26% loam, 1% superphosphate, 0.8% lime, 2% bio-organic fertilizer and 0.2% nano selenium.

[0075] The preparation method of this substrate:

[0076] Matrix preparation method:

[0077] (1) Pleurotus eryngii dregs treatment: smash the dregs of Pleurotus eryngii, dry them in the air, add water, and control the moisture content of the dregs of Pleurotus eryngii in 60% to 70% (judgment method is: grab a handful of dregs of Pleurotus eryngii, Seeing that the watermark does not drip, it is advisable to disperse when it hits the ground).

Embodiment 2

[0100] Embodiment 2 taro seedling raising method

[0101] Seedling-raising substrate and preparation method thereof are the same as in Example 1.

[0102] (1) Selection of seed taro: Select a healthy and smooth seed taro with a single weight of 30-50 g as the seed taro. After the seed selection, dry the seed taro for 2 days to remove the scales on the taro.

[0103] (2) Treatment of taro seeds: Soak with 25% amida suspension + 70% thiophanate-methyl 800 times solution for 5-10 minutes, then dry for later use.

[0104] (3) Seedbed preparation: Choose a field with sufficient sunshine and dryness. Make a seedbed with a width of 1 meter and a length of several meters (depending on the number of yams planted). Dig a 5-8cm deep pit, spread the decomposed substrate of embodiment 1, pour water thoroughly, and wait for the next planting after leveling to raise seedlings.

[0105] (4) Seedling cultivation: place the seed taro buds treated in step (2) with their eyes facing upward nea...

Embodiment 3

[0107] Embodiment 3 taro seedling raising method

[0108] Seedling-raising substrate and preparation method thereof are the same as in Example 1.

[0109] (1) Selection of seed taro: Select a healthy and smooth seed taro with a single weight of 30-50 g as the seed taro. After the seed selection, dry the seed taro for 2 days to remove the scales on the taro.

[0110] (2) Taro block treatment: cut the seed taro into multiple seed blocks with bud eyes, each seed block has 1 to 2 bud eyes, and use 25% Amida suspension + 70% methyl Tropone Soak in Bujin 800 times solution for 2 to 3 minutes, then dry it for later use.

[0111] (3) Seedling mold preparation: select 50-hole or 72-hole plug trays, put the decomposed substrate of Example 1 into the plug trays, pour water thoroughly, and wait for the next planting to grow seedlings after being leveled.

[0112] (4) Seedling cultivation: implant the taro pieces treated in step (2) with bud eyes upward into the seedling mold prepared in...

Abstract

The invention relates to the technical field of agriculture, in particular to a taro selenium-rich organic seedling culture substrate, a preparation method thereof and a selenium-rich taro seedling culture method. The taro selenium-rich organic seedling culture substrate comprises, by volume, 65-75 parts of pleurotus eryngii residues, 24-28 parts of loam, 0.8-1.2 parts of calcium superphosphate, 0.6-1.0 part of lime, 1-3 parts of bio-organic fertilizers and 0.1-0.3 part of nano-selenium. The substrate and the taro seedling culture method are efficient and environmentally friendly and simple tooperate, seedlings are cultured in a concentrated manner, cropping indexes are improved, seed taros are saved, planting costs are reduced, variety degeneration is relieved, waste of water and fertilizers is reduced, diseases and insect pests at a seedling stage are relieved, tillering and seedling strengthening of the taros are effectively facilitated, mass production requirements are met, selenium biological enhancement of the taros is implemented by the nano-selenium, the utilization rate of the selenium is increased, toxic actions of the selenium are avoided, and a good foundation is laidfor high-quality production of the selenium-rich taros.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a taro selenium-enriched organic seedling-raising substrate, a preparation method thereof, and a selenium-enriched taro seedling-raising method. Background technique [0002] Selenium is one of the essential trace elements for the growth and development of animals and plants. Selenium deficiency can cause diseases such as cancer, anemia, and vascular disease. Therefore, selenium is known as "the fire of life" and "the king of anti-cancer". Two-thirds of the world is deficient in selenium, and 70% of counties and cities in China are deficient in selenium to varying degrees. Plants are important carriers of the selenium cycle in nature. Inorganic selenium in the soil is absorbed and assimilated by plants and transformed into organic selenium, which is transformed into selenium enzymes, selenoproteins, selenocysteine ​​and other substances after being absorbed by the human bo...
