Sage Cultivation Techniques
Sage thrives in well-drained, sandy loam or deep loam soil with good ventilation and plenty of sunlight. When planting, seeds should be sown in small clusters—3 to 5 capsules per hole. Once the seedlings emerge after about a week or when they reach a height of 5 to 10 cm, it's important to thin them out, keeping a spacing of 20 to 30 cm between each plant. This helps promote stronger growth. Different sage varieties may have varying light requirements, so it’s essential to research the specific needs of the variety you're growing before starting.
Sage can be propagated through either seeds or cuttings. Both methods are effective, but choosing the right one depends on your preference and growing conditions.
1. Seed Propagation
The best time to sow sage seeds is in spring or early autumn. To improve germination rates, soak the seeds in warm water (around 50°C) for a while, then let them cool down to 30°C and rinse them several times. You can either let them germinate at 25–30°C or soak them in water for 24 hours before sowing. Sow the seeds shallowly, cover lightly with soil, and keep the soil consistently moist. You can either sow directly in the field or start them in a nursery before transplanting.
2. Cutting Propagation
In May or June, take cuttings from the top of healthy branches that are not too tender. Cut the stems into 5 to 8 cm sections, remove the lower leaves (leaving 2 to 3 leaves at the base), and insert them into a seedbed at a spacing of 5 cm by 5 cm, about 2.5 to 3 cm deep. After planting, water thoroughly and cover the area with plastic film to maintain moisture. Roots typically appear within 20 to 30 days. At this point, transplant the cuttings into the main field with a spacing of 45 to 50 cm between rows and 25 to 30 cm between plants.
Once established, sage requires regular weeding, especially during dry periods. Water as needed, and make sure to drain excess water after heavy rains. During the growing season, apply fertilizer 2 to 3 times, using approximately 5 kg of urea per mu. In northern regions of the Yangtze River, it’s advisable to cultivate the soil around the plants in late fall—up to 20 cm deep—before winter sets in. In spring, water the soil to help the plants germinate. In southern China, sage can usually survive the winter without any additional protection.

The Linear Gradient Filter has the ability of high integration, and has the irreplaceable advantage in the miniaturization and lightweight design of spectral instrument.
linear gradient filter using continuous coating method, based on multi-layer wedge-shaped film structure to achieve spatial continuous changes in the filter characteristics. The slope of the film can be adjusted according to the dispersion demand to obtain the target linear rate of change.
