Problems solved by technology

Inorganic substrates are difficult to decompose after use, causing environmental pollution. For example, rock wool is widely used as a cultivation substrate in foreign greenhouse production. Its excellent water and fertilizer retention properties improve the yield and quality of greenhouse vegetables, but it is difficult to decompose after use and pollute the environment.

Embodiment 1

[0020] (1) First, cut the green corn stalks into 5cm small pieces, stack them in a trapezoidal shape, cover the top and surrounding areas with plastic film, press them tightly, and cover them firmly. Place a thermometer on the top of the trapezoidal pile to measure the temperature of the pile. The temperature of the pile body rose sharply to 65°C in the first 4 days, and then decreased. When the temperature of the pile body dropped to room temperature, the corn stalks were already decomposed.

[0021] (2) Fully mix fresh pig manure, quicklime and clay at a ratio of 12:1:1, stack them in a trapezoidal shape, and cover the top and surrounding areas with plastic film. And use a thermometer to measure the temperature of the pile body. When the temperature of the heap rises to 45°C, uncover the film, turn the heap, water until the water content of the heap reaches 80%, and cover the film. When the temperature of the heap reaches room temperature, it becomes decomposed pig manure. ...

Embodiment 2

[0029] (1) Grinding the decomposed corn stalks to a particle size of 0.5 cm;

[0030] (2) Crush the decomposed pig manure and pass it through a 5mm sieve.

[0031] (3) Mix and stack the decomposed corn stalks, pig manure and vinegar grains at a volume ratio of 3:3:4. Water thoroughly after mixing.

[0032] (4) When the relative water content of the heap is 65%, the mixed organic matter is taken out, pressed into a cube with a side length of 15cm, and on the top of the cube, dig a cylindrical hole with a diameter of 4cm and a height of 5cm; Then leave to dry.

[0033] (5) Place the pressed cultivation matrix cube on the cultivation bed, and then bury it to the middle of the cube with soil. Cucumbers were cultivated and managed in the greenhouse according to conventional management.

Embodiment 3

[0035] (1) crushing the decomposed corn stalks, the particle size of which is 5mm;

[0036] (2) Crush the decomposed pig manure and pass it through a 5mm sieve.

[0037] (3) Mix and stack the decomposed corn stalks, pig manure and vinegar grains in a volume ratio of 3.5:3:3.5. Water thoroughly after mixing.

[0038] (4) When the relative water content of the heap is measured to be 70%, the mixed organic matter is taken out and pressed into a cube with a side length of 15 cm. On the top of the cube, dig a small cylinder with a diameter of 4 cm and a height of 5 cm. hole; then set aside to dry.

[0039] (5) Place the pressed cultivation matrix cube on the cultivation bed, and then bury it to the middle of the cube with soil. Cucumbers were cultivated and managed in the greenhouse according to conventional management.

Abstract

The invention discloses a greenhouse crop culturing substrate and a preparation method thereof, belonging to the technical field of facility cultivation. The method is implemented according to the following steps of: (1) grinding thoroughly-decomposed maize straws, pig manure and vinegar residues and passing the three materials through a 5mm sieve; (2) mixing by a weight ratio of 3.5:3:3.5 or 2.5:3:4.5 to obtain a mixture, piling up the mixture and thoroughly watering the mixture with clean water; (3) taking out a mixed organic material when the relative water content in a pile body is 60-70%, pressing the mixed organic material to a cube with a side length of 15cm, digging a cylindrical hole with a diameter of 4cm and a height of 5cm in the top of the cube, and then airing the cube; (4) placing the pressed cube of the culturing substrate onto a culturing piece, and then burying the cube to the middle with soil. The culturing substrate can be used for greenhouse crops such as greenhouse tomatoes, cucumbers and lettuce. Especially for soil with serious successive cropping obstacles, the successive cropping obstacles can be effectively reduced.

Description

technical field [0001] This technology introduces the production method of making agricultural production wastes (corn stalks, pig manure, etc.) and industrial production wastes (vinegar grains) as cultivation substrates for greenhouse crops (cucumber). It belongs to the technical field of facility cultivation. Background technique [0002] Agricultural waste such as crop stalks, livestock and poultry manure in agricultural production and vinegar residues in the production of balsamic vinegar contain rich nutrients and have a very high recycling value. However, due to the limitations of traditional agricultural production methods, the use of agricultural waste is relatively simple, through burning and farmyard manure. Aiming at the problems of large input of chemical fertilizers and pesticides, soil continuous cropping obstacles, and serious damage from diseases and insect pests in greenhouse production in our country, the present invention uses agricultural and industrial ...
