Special nutrient solution for hydroponic culture of tomatoes

Abstract

The invention relates to a special nutrient solution for hydroponic culture of tomatoes. The nutrient solution comprises water as a solvent, and molasses, potassium fulvic acid, seaweed powder, sucrose phosphate, soybean powder and citric acid as solutes. Compared with the prior art, the special nutrient solution has the advantages that the main components are from plants, waste liquid is easy tohandle, and the environmental compatibility is good; industrial by-products such as molasses and soybean powder can be reused, and resources are effectively saved; the special nutrient solution is simple to prepare, has low equipment requirements, is easy to popularize, and has a broad market.

Description

technical field [0001] The invention relates to the field of soilless cultivation nutrient solution, in particular to a special nutrient solution for tomato hydroponics. Background technique [0002] Hydroponics is a new type of soilless plant cultivation method, the core of which is to directly infiltrate the root system of the plant in the nutrient solution, which can replace the soil and provide the plant with growth factors such as water, nutrients, oxygen, etc., so that the plant can Grow normally and complete the entire life cycle. This nutrient solution cultivation mode has the advantages of high crop yield, fast growth, good quality, water saving and fertilizer saving, and also avoids various diseases and salt accumulation that often occur in the soil cultivation process. [0003] Generally, we divide the traditional nutrient solution formula into two stages. The first stage is a pure inorganic nutrient solution designed to meet the needs of plant growth. It simply ...

Problems solved by technology

[0003] Generally, we divide the traditional nutrient solution formula into two stages. The first stage is a pure inorganic nutrient solution designed to meet the needs of plant growth. It simply supplements the chemical components needed for plant growth, which is likely to cause nutritional waste and the plant growth rate is low, the quality is not high, and the salt concentration in the waste liquid is high, which increases the pressure on the environment and soil; the second stage is to add organic components and special chemical elements to the pure inorganic nutrient solution to prepare inorganic -Organic nutrient solution

Among them, the inorganic-organic nutrient solution contains sufficient nutrients, which has the advantages of promoting plant growth, improving vegetable quality, and saving fertilizers. However, the preparation process of different organic ingredients is different, the product preparation process is complicated, and it is difficult to popularize. At the same time, it lacks experienced nutrition experts. liquid formula

[0004] At present, most of the nutrient solutions used on the market are inorganic nutrient solutions. This kind of nutrient solution is mainly an aqueous solution of chemical fertilizers, which is simply prepared to meet the nutrients required for plant growth, and has a greater pressure on the environment.
