Tomato facility organic cultivation soilless culture solution and use method

Abstract

The invention relates to a tomato facility organic cultivation soilless culture solution, which comprises: 100-200l of biogas slurry, 5-10g of sodium selenite, inorganic salt component and water. Thefermentation preparation process of the biogas slurry includes: adding a mixture of rice bran, fern root, perlite, straw, sludge, animal dung, corn flour and peanut shell chips into a biogas slurry fermentation pool for fermentation for 50-80 days. The tomato facility organic cultivation soilless culture solution provided by the invention is added with sodium selenite, can add organic selenium element to the cultivated tomatoes to acquire selenium-rich tomatoes, which have fuller ruddiness than the original ones without adding of sodium selenite, the color and cost are pleasing, the added value of tomatoes is increased, the yield of the obtained selenium-rich tomatoes is 20-25% higher than that of other cultivation methods, and the selenium content is as high as 0.06-0.15mg/kg.

Description

technical field [0001] The invention relates to the technical field of facility agriculture, in particular to a soilless culture solution for facility organic cultivation of tomatoes and a use method thereof. Background technique [0002] Tomatoes in my country are mostly cultivated in the field, and the nutritional value and taste are not paid enough attention to. However, in recent years, tomato cultivation has gradually adopted hydroponics methods. Hydroponics is the use of modern bioengineering technology, using physical, chemical, and biological engineering methods to domesticate ordinary plants and flowers. It has the characteristics of high practicability, strong operability, short plant growth cycle, and high ornamental value. At its core, the plant rhizome is fixed in the planting basket and the root system naturally hangs down into the plant nutrient solution. This nutrient solution can replace the natural soil to provide water, nutrients, oxygen, temperature and ...

Problems solved by technology

At present, there are few reports about the special nutrient solution in the tomato hydroponic method. Common nutrient solution is usually used on the market, which is not developed according to the growth characteristics of tomato. Therefore, a soilless nutrient solution specially for tomato is developed to improve tomato The output, taste, etc., have a great need
