I like the cold and humid climate, with direct light and strong cold resistance. Seeds can be stored in the shade, and embryos have morphological and physiological characteristics.
The former requires a temperature change of 20- 10℃, and the latter requires a low temperature of 2-4℃, each of which takes 3-4 months, and the seeds that are not ripened cannot germinate. Strict soil requirements, suitable for planting in sandy loam and humus loam with rich organic matter and good permeability, avoiding continuous cropping.
cultivation techniques
Seed reproduction is the main way to accelerate germination. Mix 1 seeds with 3 grains of river sand, and put them in the germination box. Put it in an appropriate place indoors or outdoors to accelerate germination, and pay attention to regular inspection. Control the temperature and temperature of sowing. Fusong in Jilin often sows dry seeds in late June. In Ji 'an and other places, the seeds that were not dried in the same year were sown in early August, or the seeds that accelerated germination were sown in spring and autumn.
Cover the border, cover the broken straw or semi-rotten leaves after emergence, loosen the soil and weed, usually 3-5 times a year. Prevent soil hardening, eliminate weeds, cultivate soil and support seedlings. Topdressing organic fertilizer on the root side and ditching, spraying calcium superphosphate or trace elements on the leaf surface. Do a good job of supporting seedlings, arranging flowers and hanging curtains before adjusting Yang. Sparse flowers and pick buds, leave Taneda, and sparse the middle flower buds of inflorescence 1/3- 1/2 at the beginning of flowering. In the production field, all flower buds are picked before flowering.
