Problems solved by technology

With the development of soilless cultivation technology, intensive seedling cultivation technology is generally adopted for tomato. Moreover, tomato has a well-developed root system, strong regeneration ability, and is sensitive to changes in the physical and chemical properties of the substrate. In China, domestic peat is mostly used as raw material for substrate preparation. The matrix formula is peat: vermiculite: perlite = 3:1:1, and the winter formula is peat: vermiculite: perlite = 6:1:3. Although it can meet the needs of tomato growth, the matrix formula is relatively simple. Follow-up The workload of fertilization is heavy, and improper fertilization can easily cause physiological diseases

Embodiment 1

[0052] Embodiment 1, the mass parts of each component of composite matrix is:

[0053] Vermiculite: 30 parts;

[0054] Vermicompost: 3 parts;

[0055] Peat: 8 parts;

[0056] Furnace ash: 30 parts;

[0057] Perlite: 7 parts;

[0058] Nutrient solution: 6 parts;

[0059] The parts are all parts by mass.

[0060] Wherein, preferably, the nutrient solution includes distilled water, calcium nitrate tetrahydrate, potassium nitrate, potassium dihydrogen phosphate, urea, magnesium sulfate heptahydrate and boric acid, specifically, in each liter of nutrient solution, its components and contents are as follows:

[0061] Calcium nitrate tetrahydrate: 1200-1250 mg / L;

[0062] Potassium nitrate: 390-400 mg / L;

[0063] Potassium dihydrogen phosphate: 200-215 mg / L;

[0064] Urea: 40-55 mg / L;

[0065] Magnesium sulfate heptahydrate: 450-480 mg / L;

[0066] Boric acid: 2.3-2.5 mg / L;

[0067] The balance is distilled water.

Embodiment 2

[0068] Embodiment two, in every liter of nutrient solution, its component and content are as follows:

[0069] Calcium nitrate tetrahydrate: 1225 mg / L;

[0070] Potassium nitrate: 395 mg / L;

[0071] Potassium dihydrogen phosphate: 210 mg / L;

[0072] Urea: 50 mg / L;

[0073] Magnesium sulfate heptahydrate: 460 mg / L;

[0074] Boric acid: 2.3mg / L;

[0075] The balance is distilled water.

[0076] Adjust the pH of the composite matrix to be 5.8-6, and the EC value is 0.8-0.9 mS / cm. The composite matrix composed of Example 1 and Example 2 is used to grow tomato seedlings. The workload of subsequent fertilization and the growth of tomato seedlings are good, and the germination rate is greater than 93%.

[0077] By adopting the composite substrate of the invention, the water holding capacity of summer seedlings can be improved, fertilizer materials can be reduced, the nutrient solution is equipped with the nutrients required for tomato seedling cultivation, the formula of the nu...

Abstract

The invention discloses a compound seedling culture medium special for tomato. Preferably, the compound medium comprises, by mass, 20-40 parts of vermiculite, 2-4 parts of wormcast, 5-12 parts of turf, 25-35 parts of cinder, 5-10 parts of perlite and 3-8 parts of a nutrient solution. Preferably, the nutrient solution comprises distilled water, calcium nitrate terahydrate, potassium nitrate, monopotassium phosphate, urea, magnesium sulfate heptahydrate and boric acid. By adopting the compound medium, the water-retaining capability for summer seedling culture can be improved, and the consumptionof fertilizer can be reduced; the nutrient solution contains nutrients required for tomato seedling culture, components in the nutrient solution formula are increased, and the subsequent fertilization workload is reduced.

Description

technical field [0001] The invention relates to a special seedling-raising composite substrate for tomato. Background technique [0002] The fruit of tomato is rich in nutrition and can be eaten raw, cooked, processed into tomato sauce, juice or canned as a whole fruit. It is not only a delicacy in dishes, but also a beauty in fruits. . With the development of soilless cultivation technology, intensive seedling cultivation technology is generally adopted for tomato. Moreover, tomato has a well-developed root system, strong regeneration ability, and is sensitive to changes in the physical and chemical properties of the substrate. In China, domestic peat is mostly used as raw material for substrate preparation. The matrix formula is peat: vermiculite: perlite = 3:1:1, and the winter formula is peat: vermiculite: perlite = 6:1:3. Although it can meet the needs of tomato growth, the matrix formula is relatively simple. Follow-up The workload of fertilization is heavy, and impr...
