Problems solved by technology

If the environment is not properly controlled during the seedling raising process, the seedlings will easily grow excessively, resulting in a decline in the quality of the seedlings, which in turn will affect growth, flower bud differentiation, fruit set and fruit development, and ultimately affect the yield and quality of cucumbers
Intensive seedling cultivation can more effectively improve production efficiency and product quality, but the current facility conditions can easily lead to the phenomenon of low temperature and low light, and low temperature and low light are the main reasons for the excessive growth of seedlings

Embodiment 1

[0012] 1.1 Materials

[0013] Taking common cucumber as the test material, the experiment was carried out in November 2015 at the College of Horticulture, South China Agricultural University, Guangzhou. Standard 72-hole plastic trays are used for seedling cultivation, and peat soil: coir peat (1:1) is used as the substrate for seedling cultivation.

[0014] The supplementary light LED lamp adopts an adjustable lamp tube, and the effective photosynthetic light quantum density ratio of red and blue light is 1:1 (1R1B), 1:2 (1R2B) 2 treatments, with natural light as the control (CK); the wavelength of red light is: 650nm, The blue light wavelength is: 430nm, adjust the power supply current of the LED lamp to make the supplementary light intensity reach 50μmol·m -2 ·s -1 .

[0015] 1.2 Methods and results

[0016] Cucumber seeds were soaked and germinated, and were sown in Lubai on December 10, 2015. Each treatment was repeated 3 times, and each repetition had 55 seedlings. T...

Abstract

The invention discloses a method for adopting an LED (Light Emitting Diode) lamp for supplementing cucumber seedlings with light. The method comprises the following steps: adopting red and blue light combination for supplementing the cucumber seedlings with light under the condition of natural low light level (light intensity less than or equal to 35micromol.m2.s1), wherein the wavelength of the red light is 630-650nm, the wavelength of the blue light is 430-450nm and the density ratio of effective photosynthetic light quantum of the red light and the blue light is 2 to 1(2R1B) or 1 to 2(1R2B); adjusting the current of LED lamp power supply, for achieving the supplementary light intensity of 50-100 micromol.m2.s1; supplementing light at regular time by adopting a timing controller, wherein the light supplementing time is from 6 am to 6 pm in each day. According to the method provided by the invention, the LED lamp combined with different red and blue light ratios is adopted for supplementing the generally cultured cucumber seedlings with light; the method has the obvious boosting effect on the cucumber seedlings; the stem diameter, complete stool weight, strong seedling index, single plant leave area, root activity, net photosynthetic rate, SOD activity and POD activity of the cucumber seedlings can be effectively increased; the culturing for strong seedlings is realized.

Description

technical field [0001] The invention relates to the technical field of cucumber seedling cultivation, in particular to a supplementary light method for cucumber seedling cultivation with LED lights. Background technique [0002] The growth of plants is achieved through the storage of organic matter through synthesis, so light plays a pivotal role in the growth and development of plants. Vegetable seedling raising is an important part of vegetable cultivation. If there is continuous rainy weather, it will easily lead to insufficient photosynthesis of seedlings, hinder the synthesis of organic matter in plants, and seriously inhibit the normal development of seedlings. The robustness and development of seedlings will directly affect the growth and development of plants, and then affect the flowering and fruiting of plants, thereby affecting the growth and economic benefits of vegetable planting in the current season. [0003] Among them, cucumber is a widely cultivated vegeta...
