Nutrient solution special for soilless culture of melons as well as preparation method and application of nutrient solution

Abstract

The invention discloses a nutrient solution special for soilless culture of melons as well as a preparation method and application of the nutrient solution. The nutrient solution is prepared from urea, potassium pyrophosphate, urea phosphate, EDTA (Ethylene Diamine Tetraacetic Acid) copper, EDTA iron, EDTA manganese, EDTA zinc, EDTA calcium, EDTA magnesium, polypeptide amino acid, betaine, polyglutamic acid, potassium polyaspartate, potassium phosphite and water. The nutrient solution has the advantages that the nutrient solution is simple in preparation process and comprehensive in nutrient substance, contains all mineral elements required by growth and development of melon plants, also contains organic small molecular substances such as amino acid and the like, overcomes the defect that two or more nutrient solutions are required to be mixed in a traditional scheme, and all the component nutrients can coexist and do not generate the phenomena of precipitation, flatulence and the like. The nutrient is reasonable and comprehensive, is easily absorbed and utilized by plants, is not easy to lose, and can effectively guarantee high quality and high yield of melon plants.

Description

technical field [0001] The invention relates to a special nutrient solution for soilless cultivation, in particular to a special nutrient solution for soilless cultivation of melons and its preparation method and application. Background technique [0002] Melon crops are deeply loved by consumers because of their rich amino acid and vitamin content, sufficient water, and unique flavor. In recent years, the planting area of ​​melons in my country has increased year after year, ranking first in the world. With the improvement of people's living standards and consumption capacity, the demand for high-quality and safe melons is becoming more and more urgent. Soilless cultivation technology emerges at the historic moment under this new situation. [0003] Soilless cultivation refers to a cultivation method in which water, peat or forest leaf mulch, vermiculite and other media are used as the substrate for the root system of the plant to fix the plant, and the root system of the...

AI Technical Summary

Problems solved by technology

[0006] 1) Precise fertilization is not based on the characteristics of the fertilizer requirements of melon crops or according to the characteristics of the fertilizer requirements of melon crops in different growth periods. If the nutrients are insufficient, nutrient deficiency will occur. On the contrary, the nutrients will cause stress to the plants, which is not conducive to plants. growth and high-quality and high-yield;

[0007] 2) Traditional fertilizers lack organic nutrition and only contain mineral elements

Since soilless cultivation has left the soil organic biosphere, unlike the rich microbial populations in the soil, the organic small molecule nutrients decomposed by microorganisms are seriously lacking in soilless cultivation (especially hydroponics), which is also not conducive to the high quality of plants. high yield;

[0008] 3) Due to the rich nutrients in soilless culture, suitable water and nutrients are very suitable for the reproduction of some pathogenic bacteria, which will bring a lot of diseases and toxic substances, which require people to use more chemical fungicides to control The occurrence of diseases is also not conducive to high quality, high yield and cost control
