Problems solved by technology

Light is one of the most important environmental factors affecting plant growth and development. It has a significant impact on plant photosynthesis, nutrient metabolism and other processes. There have been many reports on improving the growth, yield and quality of vegetables by supplementing light, but The problem is that the light quality, light intensity and time of supplementary light are not clear, the difference is very large, and the corresponding energy consumption is also high, which has become an important limiting factor affecting the application of supplementary light technology
The technology of improving the quality of seedling vegetables through intermittent light supplement, especially blue-violet light intermittent light supplement before harvesting, has not been reported yet.

Embodiment 1

[0014] 1.1 Test materials and test methods

[0015] The plant material used in the experiment was Chinese cabbage. The cultivation of pak choy seedlings was carried out in the College of Horticulture, South China Agricultural University. On August 5, 2016, the seeds were sown in 50-hole trays, with 2-3 full seeds in each hole. The substrate is a mixed substrate of peat and coconut peat. Spray with tap water before germination. After the cotyledons are flattened, the seedlings are thinned, leaving only one seedling in each hole. Water soluble fertilizer once in the morning and evening according to the weather conditions. The water soluble fertilizer contains 20% N, 20% P, 20% K and other trace elements. The nutrient solution is EC 1.5ms / cm, pH6.5. On August 17, when When the young cabbage grows to two true leaves, the blue-purple LED intermittent supplementary light treatment is carried out. The supplementary light duration is 6h / d, the supplementary light time is 6:00-18:00...

[0025] 2.1 Test materials and test methods

[0026] The plant material used in the experiment was Chinese cabbage. The cultivation of pak choi seedlings was carried out in the College of Horticulture, South China Agricultural University. On October 7, 2016, the seeds were sown in 50-hole trays, with 2-3 full seeds in each hole. The substrate is a mixed substrate of peat and coconut peat. Spray with tap water before germination. After the cotyledons are flattened, the seedlings are thinned, leaving only one seedling in each hole. Water soluble fertilizer once in the morning and evening according to the weather conditions. The water soluble fertilizer contains 20% N, 20% P, 20% K and other trace elements. The nutrient solution is EC 1.5ms / cm, pH6.5. On October 21, when When the young cabbage grows to two true leaves, it is treated with blue-purple LED intermittent supplementary light. Take no supplementary light as the control, and the supplementary light wavelength is 430nm...

Abstract

The invention discloses a method for utilizing blue-violet light LED intermittent light supplementation to improve the quality of seedling vegetables. According to the method, 5-7 days before the seedling vegetables are harvested, the blue-violet light LED intermittent light supplementation is conducted on the seedling vegetables for 6-7 hours every day for 5-7 days, soluble sugars, vitamins, total phenols, flavonoids, glucosinolates and other nutrients are increased and accumulated in the bodies of the seedling vegetables, and the antioxidation capacity of FRAP and DPPH are improved at the same time; during the intermittent light supplementation, a mode of supplementing light for one hour, stopping light supplementation for one hour and then supplementing light for one hour is adopted till the light supplementation time reaches 6-7 hours; the wavelength of blue-violet light is 400-430 nm, the illumination intensity is 30-50 w / m<2>, and the method is suitable for the cultivation of theseedling vegetables. According to the method, by conducting the simple blue-violet light LED intermittent light supplementation before the seedling vegetables are harvested, the quality of the vegetables is effectively improved, the energy consumption for light supplementation is reduced, and the method is simple, low in cost and reliable in result.

Description

technical field [0001] The invention relates to the technical field of regulating and improving the quality of seedling vegetables, in particular to a method for regulating and controlling the quality of seedling vegetables before harvesting, and in particular to a method for improving the quality of seedling vegetables by supplementing light with blue-purple LEDs. Background technique [0002] Seedling vegetable cultivation refers to a cultivation method that specializes in the production of vegetable seedlings for food. Seedlings have the characteristics of good quality, less fiber, sweet and delicious taste, and high nutritional value; secondly, due to the short growth period of seedlings, high multiple cropping index, strong ability to replenish light, large production benefits, less threat from adverse natural disasters, and occurrence of pests and diseases Less, less pesticide residues. As an emerging, high-quality pollution-free vegetable, it is constantly enriching ...
