Problems solved by technology

At present, the cultivation technology of Pleurotus eryngii in my country is constantly improving, but there are also shortcomings. The ultimate goal of our research is to obtain high-quality edible fungi through factory cultivation. Development has a great promoting effect, and many people have conducted research, and in humidity, temperature and CO 2 The research on the effect of concentration on the effect of A. apricot is relatively mature, but there are few studies on the effect of light on the growth and development of A. apricot. Light is an important environmental factor for the growth and development of crops. Different growth periods have different requirements for light. Different light intensities have different effects on Pleurotus eryngii. Light plays an important role in the growth and development of Pleurotus eryngii. Light has a significant impact on the growth of Pleurotus eryngii mycelium, primordium formation, differentiation and fruiting body morphology.
In recent years, with the development of LED, its luminous efficiency has been significantly improved. LED light sources have been widely used in agriculture, such as plant tissue culture, seedling production, vegetable cultivation, sprout vegetable cultivation, and greenhouse lighting. The high price of LED is not conducive to agricultural promotion

Abstract

The invention relates to a method for promoting growth and development of pleurotus eryngii by an LED plant growth light source. The fluorescent powder exciting LED plant growth light source is prepared from fluorescent powder emitting dark red light and a blue light chip by combination, the composition of fluorescent powder is Ca14Al10Zn6O35:Mn<4+>, and the fluorescent powder is prepared with a hydrothermal method and calcined at a calcination temperature of 1000-1500 DEG C. The fluorescent powder can be effectively excited by ultraviolet-light green light of 250-510 nm, and light is emittedsignificantly in the wavelength range of 650-750 nm; an LED lamp is prepared and packaged from the fluorescent powder and organic silica gel in a mass ratio of 1:(4-20) by mixing. A fluorescent powderexciting LED can not only provide sufficient light for growth and development of pleurotus eryngii, but also can increase temperature of the growth and development space of the pleurotus eryngii by 2-5 DEG C, and growth time of the pleurotus eryngii can be effectively shortened on the premise that quality of the pleurotus eryngii is improved. The method is suitable for industrial production of the pleurotus eryngii, increases benefits and can be widely popularized.

Description

technical field [0001] The invention belongs to the technical field of promoting plant growth by an LED light source, and in particular relates to a method for promoting the growth and development of Pleurotus eryngii by using an LED plant growth light source. Background technique [0002] Pleurotus eryngii is a new variety of rare edible fungus that integrates edible, medicinal and therapeutic purposes. It has been successfully developed and cultivated, also known as celery.
