Problems solved by technology

However, the light source of this kind of plant growth light adopts the mode of blue light chip and red light chip to obtain a line spectrum, which is far from the sunlight and far away from the original growth environment of plants; and the price of the red light chip is 2 times that of the blue light chip. - More than 3 times, at the same time, the double-chip packaging mode itself increases the difficulty of the process and indirectly increases the production cost, thus restricting the application and promotion of LED plant lighting devices in the chip-plus-chip mode

Embodiment 1

[0027] Red phosphor Sr was prepared under the conditions of 1500-1700°C and 1.0-2.0 MPa by high-temperature solid-state method 0.5 Ca 0.5 SiAlN 3 : Eu 2+ (For its emission and excitation spectrum, see figure 1 , See the real object and the electron microscope picture figure 2 ) mixed with organic silica gel at a mass ratio of 1:10, and packaged with a blue light chip to form a light source device (see image 3 A); Pepper seeds are germinated in a constant temperature box at 25°C for 6 days and then moved to a special substrate for seedling cultivation to carry out floating seedling cultivation, and the floating pots are respectively placed on supports equipped with LED plant growth light sources (see the diagram for a schematic diagram) Figure 4 ) and on the bracket installed with fluorescent lamps (see the schematic diagram of the spectrum of fluorescent lamps Figure 5 ), the length of the iron frame is 69cm, the width is 23cm, and the layer spacing is 17cm; the light...

Embodiment 2

[0036] The red phosphor Sr 0.5 Ca 0.5 SiAlN 3 : Eu 2+ Mix it with organic silica gel at a mass ratio of 1:5, and package it with a blue light chip to form a light source device (see image 3B); okra seeds were germinated in a 25°C incubator for 2 days, and then moved to a special substrate for seedling cultivation for floating seedling cultivation, and the floating pots were placed on the support platform equipped with LED plant growth light sources and the support platform equipped with fluorescent lamps. (For a schematic diagram of the spectrum of a fluorescent lamp, see Figure 5 ), the length of the iron frame is 69cm, the width is 23cm, and the layer spacing is 17cm. Light intensity is represented by light quantum efficiency, which is controlled at 100-200μmol / m 2 / s; photoperiod 12h / d.

[0037] After being cultivated for 45 days, the seedling morphology (plant height, stem diameter, root length, fresh sample quality, dry sample quality, strong seedling index) and p...

Embodiment 3

[0045] The red phosphor Sr 0.5 Ca 0.5 SiAlN 3 : Eu 2+ Mix it with organic silica gel at a mass ratio of 1:3, and package it with a blue light chip to form a light source device (see image 3 C); Soak the tomato seeds in water to sterilize after airing, then move the seeds to the special matrix for seedling cultivation to carry out floating seedling cultivation, and place the floating pots on the iron frame platform with LED plant growth light source and the support platform with fluorescent lamps respectively (For a schematic diagram of the spectrum of a fluorescent lamp, see Figure 5 ), the length of the iron frame is 69cm, the width is 23cm, and the layer spacing is 17cm. Light intensity is represented by light quantum efficiency, which is controlled at 100-200μmol / m 2 / s; photoperiod 12h / d.

Abstract

The invention relates to a method utilizing LED plant growth light source to promote seedling nursing of solanaceous vegetables. First, red phosphor MSiA1N3: Eu2+(Ms equals to either Ca, Sr, or Ba) or K2AF6: Mn4+( Ms equals to either Si, Al, Ti or Ge); a laser spectrum is within a 300 to 470nm wavelength range and an emission spectrum is within a 600-660nm range; the phosphor and organic silica gel are mixed according to weight by a proportion of 1 to 1 and then sealed with a blue light chip to form a light source component; and the light source can be applied to seedling nursing for solanaceous vegetables. The emission spectrum can be well matched with a plant photosynthesis absorbing spectrum via the phosphor stimulating LED lamp, so high light-supplementing efficiency can be achieved; in light of solanaceous vegetable growth, seedlings can grow quickly and healthily; dry weight and fresh weight can be obviously improved; seedling nursing time can be shortened; the method utilizing LED plant growth light source to promote seedling nursing of solanaceous vegetables can be applied to fields of indoor seedling-nursing, cultivation and seedling factorization for solanaceous vegetables.

Description

Technical field: [0001] The invention belongs to the technical field of promoting plant growth by LED light sources, and in particular relates to a method for promoting seedling cultivation of solanaceous vegetables by utilizing LED plant growth light sources. Background technique: [0002] Nightshade vegetables refer to vegetables in the nightshade family, including okra, peppers, and tomatoes. It has the characteristics of high yield, long harvest period and rich nutrition. Among them, pepper has the highest vitamin C content, 100mg per 100g fresh product, which is 3-4 times that of ordinary vegetables. Okra, also known as wool eggplant, is native to Africa and more common in southern China. Its edible part is the fruit pod, which is divided into green and red. It tastes crisp, tender and juicy, smooth and not greasy, and has a unique fragrance. The seeds can be squeezed for oil and have very high nutritional value. Tomatoes are delicious and can replace fruits and beco...
