Problems solved by technology

[0003] Substrate cultivation has the problems of sufficient nutrients in the early stage, lack of nutrients in the later stage, and poor water retention, and the raw materials used in many substrates are mostly perlite, coconut shell, river sand and other materials, which have poor water retention and are easily powdered and lost when watering, which restricts Substrate use range and lifespan
Hydroponic cultivation, because the plant root system is soaked in the nutrient solution for a long time, although it provides continuous and sufficient nutrition for plant growth, the root system can be exposed to very little oxygen, which is not conducive to plant growth.
Aeroponic cultivation can take into account the supply of nutrients and the required oxygen at the same time, but it is limited to the volume of the cultivation box, atomization equipment, etc., which limits its development

Abstract

The invention belongs to the technical field of cultivation, and particularly relates to nutrient gel for soilless culture. The hydrogel containing nutrients required by plant growth is prepared through grafting modification of alginic acid and chitosan, the contained nutrients can be slowly released, sufficient nutrients can be continuously provided for plant growth, a root system can breathe oxygen, and the hydrogel is not affected by equipment conditions, regional environments and the like.

Description

technical field [0001] The invention belongs to the technical field of cultivation, and in particular relates to a nutrient gel for soilless cultivation. Background technique [0002] Soilless cultivation refers to the method of cultivating crops and raising seedlings with substrates without using natural soil. It is mainly used in the production of flower seedlings or melons, fruits and vegetables. Compared with traditional soil cultivation, it is a method that saves water, fertilizer and The high-yield, high-quality and advanced cultivation technology of Gonggong can improve crop yield and quality, avoid soil continuous cropping obstacles, and is not limited by geographical conditions and other conditions. The main forms of existing soilless cultivation are substrate cultivation, hydroponic cultivation and mist cultivation. Substrate cultivation is to grow plant roots in a solid substrate and make crops grow by delivering nutrient solution; hydroponic cultivation is to gro...
