Description
Technical Field
The invention belongs to the technical field of medicinal plant cultivation, and particularly relates to a method for regulating and controlling flowering time of crocus sativus and improving filament quality.
Background
Stigma croci, also known as crocus sativus, is a plant of the genus crocus of the family Iridaceae, is rich in natural active ingredients such as crocin, etc., has pharmacological activity of protecting central nervous system and cardiovascular and cerebrovascular diseases, and can be used as a raw material of soluble natural pigment dye and perfume. The yield of stigma croci is extremely low, and more than one hundred flowers are needed for producing 1g of dry stigma croci, so that the market price of stigma croci is high, and the stigma croci is called as "plant gold".
The saffron is produced in Iran, spanish and other places, the introduction cultivation is started in the last 60 th century, and the current saffron cultivation mode of China mainly adopts two-stage cultivation method, namely 'indoor soilless cultivation and flower picking' and 'large Tian Pei breeding ball' two stages, namely, the seed ball breeding is completed in the field from 11 months to 5 months of the next year, after seed ball harvesting, the artificial selection of saffron seed balls is completed in the room from 6 months to 11 months, the seed balls are dormant in summer and flower bud differentiation, and the seed ball is put on a frame for cultivation, and the flower silk harvesting process is completed. In a room with accurately controlled temperature, humidity and illuminance, the seed balls finish flower bud differentiation and flowering by means of self-stored nutrients, and then the flower filaments are manually harvested and processed.
In general, stigma croci is flowering from mid-late undecyle to mid-late undecyle, and one flower is opened from flower bud to early stage, and is opened to first stage for about 24 hours each. Flowers should therefore be picked on the day of opening, the time of picking being before the flowers are full. The method is characterized in that the method generally comprises the steps of collecting the pollen twice a day at 8-10 a.m. and 1-3 a.m. in the afternoon, peeling off the filaments, and easily attaching pollen to the column heads of the pistil after the pollen collection, so that the quality grade of the filaments is directly affected. Because the flowering time of the saffron is concentrated, the flower picking and the filament stripping are both carried out manually, the time is compact, the workload is large, and if the picking is not timely, the quality and the quality of the filament are greatly affected.

Materials, reagents and the like used in the examples described below are commercially available unless otherwise specified.
Example 1
1. Selecting newly-dug disease-free seed balls (Shanghai Chongming-producing area) in the current year, dividing the seed balls into 30-35 g (A), 25-30 g (B), 20-25 g (C) according to the weight of the seed balls, selecting 200 seed balls for each grade, placing a plastic basket for each 50 seed balls, setting four light treatments, placing one basket for each seed ball of A, B, C grades under each treatment, and putting the seed balls on a shelf for cultivation in a cultivation room in the last ten days of August. In the period from the last March to the last September, the indoor temperature is controlled at 20-25deg.C, the humidity is 80%, and the light is mainly weak light (300-600 Lux).
2. When the main buds grow to 2-3cm, recovering the illumination intensity to 3000-4000Lux, illuminating for 10h and darkness for 14h, simultaneously wiping off side buds, reserving 3 main buds from more than 30g of large bulbs, reserving 2 main buds from 25-30 g of bulbs, reserving 1-2 main buds from 20-25 g of small bulbs, and keeping the temperature to 18-22 ℃ and the humidity to 70-80%.
3. When the main bud grows to 6-8 cm, on the basis of illumination for 10 hours (8:00-18:00) per day, three light sources of red light (R), blue light (B) and white light (W) are respectively used for delayed light supplementing treatment, the light supplementing intensity is 4000-5000Lux, the light supplementing time is 6:00-8:00 per day, the evening is 18:00-20:00, the time period is not supplemented with light and is a common group (CK), and the night is 20:00-6:00 in a dark period. And (3) carrying out light supplementing treatment until the flowering period of the stigma croci is finished, taking the red stigma to record the indexes such as the weight, the length and the like of the stigma, and finally drying for later use.
As a result, as shown in table 1, the white light supplement was able to bloom one week earlier than the normal group, the red light supplement was not much different from the non-light supplement flowering time, and the blue light supplement was able to delay one week flowering than the normal group.
TABLE 1 flowering time and flowering rate of saffron under different light supplementing treatments
As a result, as shown in FIG. 1, the fresh weight of the filaments under different light supplementing treatments was not significantly different from that under no light supplementing. As a result, as shown in FIG. 2, the white light is longer than the light without the light supplement, the red light is not obviously different from the light without the light supplement, and the length of the column head is slightly reduced under the light with the blue light supplement. In summary, the method can control flowering time, disperse artificial pressure of flower picking and filament picking through different light supplementing treatments, ensure filament quality and appearance, and reduce economic loss.
