Problems solved by technology

It can solve the cumbersome organization and selection of materials; the configuration of business components requires certain professional technical knowledge and special equipment, which is not easy for ordinary people to control. At the same time, due to the looseness of the substrate, it can only be planted in a special place, and the production efficiency is low. , the labor intensity is high, and it will pollute the environment. Due to the poor performance of operation and use, it restricts the development, popularization and application of soilless cultivation technology.

Embodiment 1

[0077] A soilless nutrient matrix of the present invention is composed of the following components: 100g of carbonized grass powder; 450ml of binder; 1g of yeast; 150g of organic fertilizer; 1ml of nitric acid or phosphoric acid. The carbonized grass powder is carbonized straw; the binder is polyvinyl alcohol. Its preparation steps are,

[0078] (1), carbonize the straw into a strip shape corresponding to the size of the carbonization machine and store it as a raw material, and crush it to 20 mesh when used; take 100g of such crushed carbonized straw;

[0079] (2), 2499 or 1799PVA raw material is heated and dissolved in a dissolution tank to make 2% PVA aqueous solution 450ml, and cooled to normal temperature;

[0080] (3) Mix the above raw materials, add 1g of yeast, 1ml of nitric acid or phosphoric acid to make a slurry, pump it into the mold with a grouting pump or make planting bricks, blocks or boards through an extruder or a board machine, dry and wet Store in stock af...

Embodiment 2

[0082] A soilless nutrient matrix of the present invention is composed of the following components: 100g of carbonized grass powder; 500ml of binder; 2g of yeast; 100g of organic fertilizer; 1ml of nitric acid or phosphoric acid. The carbonized grass powder is carbonized straw; the binder is polyvinyl alcohol. Its steps are,

[0083] (1), carbonize the straw into a strip shape corresponding to the size of the carbonization machine and store it as a raw material, and crush it to 30 mesh when used; take 100g of such crushed carbonized straw;

[0084] (2), 2499 or 1799PVA raw materials are heated and dissolved in a dissolution tank to make 500ml of 3% PVA aqueous solution, and cooled to normal temperature;

[0085] (3) Mix the above raw materials, add 2g of yeast, 1ml of nitric acid or phosphoric acid to make a slurry, pump it into the mold with a grouting pump or make planting bricks, blocks or boards through an extruder or a board machine, dry and wet Store in stock after bal...

Embodiment 3

[0087] The components and their proportions by weight are as follows: 100 g of carbonized grass powder; 475 g of binder; 1.5 g of yeast; 125 g of organic fertilizer; 1 g of nitric acid or phosphoric acid. The carbonized grass powder is carbonized straw; the binder is polyvinyl alcohol; Its steps are,

[0088] (1), carbonize the straw into a strip shape corresponding to the size of the carbonization machine and store it as a raw material, and crush it to 25 mesh when used; take 100g of such pulverized carbonized straw;

[0089] (2), 2499 or 1799PVA raw materials are heated and dissolved in a dissolution tank to make 475ml of 2.5% PVA aqueous solution, and cooled to normal temperature;

[0090] (3) Mix the above raw materials, add 1.5g of yeast, 1ml of nitric acid or phosphoric acid to make a slurry, pump it into the mold with a grouting pump or make planting bricks, blocks or boards through an extruder or a board making machine, and dry them. Storage after humidity balance. ...

Abstract

The invention discloses a soilless nutritive medium and a preparation method thereof. The soilless nutritive medium comprises the following components in parts by weight: 100 parts of carbonized grass meal, 450 to 500 parts of adhesive, 1 to 2 parts of yeast, 100 to 150 parts of organic fertilizer and an appropriate amount of nitric acid or phosphoric acid. The invention has the advantages that the medium is presented in the types of bricks, blocks and plates; the medium is light in weight and is health; the medium is hard when being dry and is soft and elastic when being wet; the medium contains various nutritive elements required by the growth of plants and is suitable for planting various flowers, plants, fruits and vegetables; fine sowing of seeds and the seedling culture can be carried out on a sheet material by means of the soilless nutritive medium and sowing equipment; the use of the medium is simple and convenient, and the effect is good; and the medium can be placed in the farmland and has the improvement action on the soil once the medium is invalidated.

Description

technical field [0001] The invention relates to a soilless nutrient matrix for planting, in particular to a moldable and recyclable soilless nutrient matrix and a preparation method thereof. Background technique [0002] With the development of my country's agricultural science and technology and the improvement of modernization, the output of agricultural and sideline products has increased year by year. With the increase of agricultural waste, especially crop straw, according to statistics, my country produces more than 800 million tons every year. Some of them are burned in the fields, which not only pollutes the environment, but also wastes a lot of straw resources; at the same time, with the improvement of the city's internationalization and the acceleration of the construction of green, environmentally friendly, hygienic and civilized cities, environmental greening has changed from nature Stepping into the courtyard, stepping into the living room, jumping up to the high-...
