The application provides a method for promoting the weight increase of saffron offsprings by enhancing illumination, comprising the following steps: transplanting the mother corms into the soil for vegetative growth after picking the filaments, the illumination intensity is 20000 Lux, and periodic maintenance management is implemented, water is supplemented once every two weeks, and the morphological indexes of the offsprings are observed, the offsprings are harvested after all the leaves wither. The experimental results show that increasing the illumination intensity reduces the expression level of CsCCD2L in the leaves, increases the content of zeaxanthin, and is conducive to photosynthesis, thereby providing nutrition for the development of the offsprings; the increase of the weight of the offsprings can significantly increase the number of flowers and improve the yield of saffron, and is expected to solve the bottleneck problem of low saffron yield.

The application relates to a method for breeding Scirpus planiculmis nutrient bulb based on hydrological regulation, and relates to a breeding method for Scirpus planiculmis nutrient bulb. The method is used to solve the problems of high cost and strong uncertainty in the existing Scirpus planiculmis bulb breeding process. The method comprises the following steps: S1, seed source collection and screening; S2, culture medium and container screening and preparation; S3, Scirpus planiculmis bulb sowing control; S4, stage hydrological regulation; and S5, Scirpus planiculmis bulb harvesting. The application sets up differential water level management based on different growth and development stages of Scirpus planiculmis, can significantly improve the quantity and quality of Scirpus planiculmis bulb breeding, and realizes bulb large-scale proliferation. The application adopts a 26cm-diameter and 30cm-depth gallon pot to breed Scirpus planiculmis nutrient bulb, about 200 bulbs can be harvested from each pot, the dry weight of the bulbs in each pot is about 360-420g, and the breeding efficiency is stably improved. The application can be used in the fields of laboratory breeding, scientific test and degenerated Scirpus planiculmis wetland ecological restoration.

This invention discloses a method for shade cultivation of saffron in high-altitude areas, relating to the field of saffron cultivation technology. Specifically, it includes seedling selection, planting selected seedlings in the field, erecting a shade net above the field to control the shading rate (75%–85%), and watering, fertilizing, and pest and disease control under the shade net. This method solves the technical problems of complex understory lighting conditions, the unclear adaptation threshold and suitable shading range for saffron to low-light environments, and the lack of scientific parameter support for understory cultivation. Using this method, a root zone and canopy environment with coordinated light, temperature, and water is created for saffron growth. The S80 method of this invention extends the entire growth period of saffron to 260–280 days, increasing the time window for photosynthetic product accumulation, effectively maintaining bulb fresh weight and diameter, and providing sufficient energy and material basis for flower development and bulb enlargement. Furthermore, its medicinal value meets and exceeds the standards of the 2020 edition of the Chinese Pharmacopoeia.
