Embodiment 1

[0016] A soilless cultivation substrate of tomato is obtained by the following preparation method:

[0017] (1) Crush the solid material to 6-9 mm and mix it evenly with cow dung at a weight ratio of 50:1 to obtain a solid matrix; the solid material is a mixture of garden leaves and sawdust.

[0018] (2) Spray the nutrient solution on the solid substrate described in step (1) and stir evenly; the weight ratio of the solid substrate to the nutrient solution is 50:1. The nutrient solution is an aqueous solution containing the following concentration components: 5 g / L of sodium nitrate, 3 g / L of urea, 2 mg / L of copper nitrate, 4 mg / L of manganese nitrate, 45 mg / L of ferrous sulfate, 3 mg / L of ammonium phosphate mg / L, ammonium molybdate 2 mg / L.

[0019] (3) Place it at 15-25°C for 11 days, and ferment naturally to obtain a soilless culture substrate;

[0020] By adopting the soilless culture medium and ordinary soil in this example to plant tomatoes, the yield of tomatoes on the...

Embodiment 2

[0022] A soilless cultivation substrate of tomato is obtained by the following preparation method:

[0023] (1) The solid material is a mixture of dead branches and straw. After the solid material is crushed to 6-9mm, it is evenly mixed with cow dung at a weight ratio of 50: 2 to obtain a solid matrix.

[0024] (2) Spray the nutrient solution on the solid substrate described in step (1) and stir evenly; the weight ratio of the solid substrate to the nutrient solution is 50:2. The nutrient solution is an aqueous solution containing the following concentration components: 6 g / L of sodium nitrate, 4 g / L of urea, 3 mg / L of copper nitrate, 5 mg / L of manganese nitrate, 65 mg / L of ferrous sulfate, 5 mg / L of ammonium phosphate mg / L, ammonium molybdate 3 mg / L.

[0025] (3) Place it at 20-30°C for 12 days, and ferment naturally to obtain a soilless culture substrate.

[0026] By adopting the soilless cultivation medium and ordinary soil in this example to plant tomatoes, the yield of...

Abstract

The invention provides a soilless culture substrate of tomato, and relates to the field of agriculture technology. The soilless culture substrate of tomato is prepared by the following preparation method: (1) crushing solid materials to the size of 6-9 mm, uniformly mixing the crushed solid materials and cow dung, and obtaining a solid substrate; (2) spraying a nutrient solution to the solid substrate according to the step (1) and uniformly mixing; (3) placing the substrate at 15-60 DEG C for 11-12 days by nature fermentation, and obtaining the soilless culture substrate; the nutrient solution is an aqueous solution containing the following components: 5-6 g / L of sodium nitrate, 3-4 g / L of urea, 2-3 mg / L of cupric nitrate, 4-5 mg / L of manganous nitrate, 45-65 mg / L of ferrous sulphate, 3-5 mg / L of ammonium phosphate, and 2-3 mg / L of ammonium molybdate. The soilless culture substrate provided by the invention can minimize insect pest existed in soil cultivation, and increase output, reduce cost, and reduce pesticide usage amount.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a soilless cultivation substrate for tomatoes. Background technique [0002] In the prior art, the population increases sharply, the cultivated land per capita decreases day by day, and the soil in arid areas and saline-alkali land is not suitable for farming. Planting crops in the soil, there are many pest eggs in the soil, and pesticides need to be sprayed frequently during the planting period, which is easy to pollute the soil, water and crops. Contents of the invention [0003] The invention provides a soilless cultivation substrate for tomatoes, which can reduce insect damage when soil cultivation is adopted, increase yield, reduce cost, and reduce pesticide usage. [0004] A soilless cultivation substrate of tomato is obtained by the following preparation method: [0005] (1) Crush the solid material to 6-9mm and mix it evenly with cow dung to obtain a solid matri...
