Problems solved by technology

The production of flower seedlings is mostly carried out in the greenhouse. Due to factors such as the light transmittance of the greenhouse roof covering material and the shading of the steel frame structure, the internal light may be significantly lower than the open-air natural environment. Therefore, light has become a key factor in the production of greenhouse flowers. An important limiting factor, insufficient light will significantly affect the growth, develop

Embodiment 1

[0036] Select the petunia variety "Chongyin" and the horny Viola variety "Little Coin". Take 400 seeds from each variety and sow them in 200 hole trays. After germination, select 270 seedlings with relatively consistent growth for further processing and observe.

[0037] Experimental program

[0038] The duration of the experiment was 4w, and it was divided into 3 treatments, with 3 repetitions for each treatment, and 30 samples for each repetition. The specific treatment and curing conditions are shown in Table 1.

[0039] Table 1 Experimental treatment scheme

[0040]

[0041] The supplementary light treatment was carried out in an artificial climate chamber, and the fluorescent lamp was the only light source, and the average light intensity was 90.71 μmol / m 2 s (converted to 6712.54 lux), measure the number of true leaves, stem and leaf dry weight, root dry weight and root-to-shoot ratio of each sample after the light experiment, and perform data analysis.

Embodiment 2

[0053] 1) Sowing

[0054] The sowing plan is determined according to the germination rate of the seeds. Generally, the seeds are sown in the hole tray for a single seed / hole. The specific environmental controls are as follows:

[0055] Temperature control: 22±1℃;

[0056] Moisture management: the relative humidity of the air should be kept above 95%, and the moisture content of the substrate should be maintained at 80-90%;

[0057] Light management: dark environment should be kept during sowing;

[0058] Fertilization management: No need to fertilize during planting.

[0059] 2) Early maintenance

Abstract

The invention provides a method for accelerating of petunia seedling growth. Supplementary lighting is carried out on petunias for 4 hours per day for 6-8 days before the petunias is for sell, a whole set of seedling production technique process is combined, the vegetative growth rate of petunia seedlings can be effectively improved, the period of the seedlings for sell can be shortened by 4-6 days, the production cycle is reduced by 14.3 % to 21.4%, or the quality of seedling products is improved under the condition of same selling time.

Description

technical field [0001] The invention belongs to the field of plant cultivation, in particular to a method for accelerating the growth of petunia seedlings. Background technique [0002] Illumination is one of the basic elements of plant growth, and moderately increasing the photosynthetically active radiation of plants is an effective way to promote plant growth and increase plant yield. The production of flower seedlings is mostly carried out in the greenhouse. Due to factors such as the light transmittance of the roof covering material of the greenhouse and the shading of the steel frame structure, the internal light may be significantly lower than the open-air natural environment, so light has become a key factor in the production of greenhouse flowers. An important limiting factor, insufficient light will significantly affect the growth, development, yield and quality of greenhouse crops. [0003] At present, the production level of domestic flower seedlings is relative...
