Micro-nano bubble water seed-soaking and germination-accelerating equipment and germination-accelerating method

Abstract

The invention relates to micro-nano bubble water seed-soaking and germination-accelerating equipment and a germination-accelerating method. The equipment comprises a seed soaking chamber, a germination accelerating chamber and a control system, wherein a seed soaking water tank is arranged in the seed soaking chamber, a gas-liquid mixing tank is connected to the outer side of the seed soaking water tank and is connected with a gas-liquid mixing pump, and the gas-liquid mixing pump is connected with an air source and a water source respectively; a seed soaking film is arranged in the seed soaking water tank, and a micro-bubble aerator is arranged below the seed soaking film; a germination accelerating disc is arranged in the germination accelerating chamber, an atomization spraying head isarranged above the germination accelerating disc and is connected with a high-pressure pump in the seed soaking chamber; and a lighting lamp, a temperature control device, a blowing device and corresponding sensors are arranged in the germination accelerating chamber. The equipment has the beneficial effects that air, oxygen or ozone are dissolved into water by virtue of a micro-nano bubble generation technique so as to form micro-nano bubble water, and the micro-nano bubble water is utilized for sterilization, disinfection and oxygenation of seed soaking water, so that seed decay caused due to fungi and bacteria can be reduced, and the rotting problem caused due to oxygen deprivation can be thoroughly solved.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a device for accelerating germination by soaking seeds in water with micro-nano bubbles and a method for accelerating germination. Background technique [0002] Seed germination is an important stage of plant individual development, and its goodness directly affects the later growth and yield formation of plants. Water is a necessary condition for seed germination. Seeds absorb water and germinate, and sufficient oxygen exposure is the prerequisite for ensuring smooth aerobic respiration of seeds and producing the energy required for germination. It is generally believed that the increase of oxygen content in water can avoid the phenomenon of "rotten seeds and buds" caused by harmful intermediate substances produced by seeds due to anoxic and anaerobic respiration. [0003] The purpose of soaking seeds is to absorb enough water for the seeds before sowing, activate the enz...
