Embodiment 1

[0017] Pretreatment of fresh cow dung: take fresh cow dung and add cow urine, stir to obtain diluted cow dung liquid, squeeze and dehydrate through a cow dung dry-wet separator, then centrifuge, filter and separate to obtain solid dry cow dung. The moisture content of solid dry cow dung is 45%-50%.

[0018] Preparation of organic fertilizer (vermicompost): Take 90kg of solid dry cow dung and pile it up for 6-8 days, with a pile height of 15-20cm, add 5kg of rotten melons and fruits, mix evenly, and lay it flat with a height of 15cm to obtain feed Put 4,000 earthworms per square meter of feeding material, and separate the earthworms after 30 days: put the feeding material with earthworms in a sieve, put them under strong light, and the earthworms will drill out from the sieve, and collect earthworms and organic fertilizers respectively.

[0019] The weight ratio of each component of the rice seedling raising substrate is as follows: 6 parts of vermicompost, 20 parts of activate...

Embodiment 2

[0022] Preparation of organic fertilizer (vermicompost): get 80kg of solid dry cow dung prepared in the examples and pile up for 6-8 days, with a pile height of 15-20cm. Waste slag (composed by weight ratio 1:1:1) is evenly mixed, then paved, and the paving height is 15cm, to obtain feed; 4000 earthworms are put into feed per square meter, and earthworms are separated after 30 days: put the feed with earthworms Put it in a sieve and put it under strong light, and the earthworms will drill out from the sieve to collect earthworms and organic fertilizers respectively.

[0023] The weight proportion of each component of the rice seedling raising substrate is as follows: 65 parts of vermicompost, 25 parts of activated sludge, 5 parts of rice or corn straw granules, 2 parts of vermiculite, and 2 parts of perlite, which are uniformly mixed.

[0024] The prepared seedling-raising matrix was used for rice seedling raising, and the obtained rice was 10.9 cm in plant height when the see...

Embodiment 3

[0026] Preparation of organic fertilizer (vermicompost): get 85 kg of solid dry cow dung prepared in the examples and pile up for 6-8 days, with a pile height of 15-20 cm, add 10 kg of rotten melons and fruits, and 5 kg of traditional Chinese medicine residue (made from honeysuckle waste residue, Achyranthes bidentata waste residue, Codonopsis pilosula waste slag (composed of weight ratio 1:1:1) is evenly mixed, and then paved at a height of 15 cm to obtain feed; 4,000 earthworms are put into feed per square meter, and earthworms are separated after 30 days: bring the feed to Earthworms are placed in the sieve and placed under strong light, and the earthworms will drill out of the sieve to collect earthworms and organic fertilizers respectively.

[0027] The weight proportion of each component of the rice seedling raising substrate is as follows: 65 parts of vermicompost, 20 parts of activated sludge, 5 parts of rice or corn straw granules, 1 part of vermiculite, and 1 part of ...

Abstract

The invention discloses a rice seedling cultivating medium prepared from cow dung. The rice seedling cultivating medium comprises the following components in parts by weight: 60-65 parts of wormcast, 20-25 parts of activated sludge, 4-5 parts of rice or maize straw particles, 1-2 parts of vermiculite and 1-2 parts of perlite. The rice seedling cultivating medium effectively utilizes cow dung and agricultural wastes, thereby being environment-friendly and low in cost, and the prepared medium is good in rice seedling cultivating effect.

Description

technical field [0001] The invention relates to the reuse of cow dung, in particular to a method for preparing a rice seedling raising substrate by using cow dung. Background technique [0002] With the increase of rice labor costs, the whole mechanization technology of rice has become one of the main methods of rice production in southern rice areas, and the industrial seedling raising technology has developed rapidly. However, the traditional plate seedling cultivation will greatly destroy the plow layer and vegetation when soil is taken, and it is difficult to cultivate strong seedlings due to insufficient nutrition; the single use of agricultural waste such as rice husks and straws as the substrate for rice seedling cultivation has high costs, low benefits, and insufficient nutrition is difficult to promote. Contents of the invention [0003] The object of the present invention is to provide a low-cost, green and environment-friendly rice seedling raising substrate in ...
