Propagation methods of Gentiana

Gentian is a perennial herb of Gentianaceae, Inner Mongolia, Hebei, Shaanxi, * *, Jiangsu, Anhui, Zhejiang and other places, born in hillside grasslands, roadsides, beaches, thickets, forest margins and under forests, meadows, with high medicinal value, reproduction of available seeds and ramet reproduction, let's take a look at the reproduction methods of Gentiana!

Growing environment of gentian

Gentian likes wet and cool climate, and is wild in mountains, slopes, forest greens and bushes. The temperature requirement of the plant during the whole growing season is quite high, and it has been growing well after introduction in Beijing area. Places with high dryness and direct sunlight and areas where the soil is too sticky and barren are not suitable for cultivation. They like fertilizers. When combined with deep ploughing land, about 8000 jin of fully rotten barnyard manure should be applied per mu and germinate in the middle of April every year. It blossoms in August, the flowering period is from August to September, the fruit matures in September, and the annual growth period is about 180-210 days.

Split-plant propagation of gentian

The ramet propagation of Gentiana was mostly carried out before the buds were unearthed in early April. All the roots were dug out and divided into small clusters, each cluster should have 1-2 small buds, and then planted according to the row spacing of 1.3 feet and the plant spacing of 0.7-1 feet, so as not to expose the buds to the soil surface, so as not to be dried by the wind.

Seed propagation of gentian

1. Autumn sowing: gentian grass is usually sown in November and sprouts in the following spring. In order to sow evenly, mix appropriate amount of fine sand or humus into the seeds and sow them with strips.

2. Spring sowing: gentian should be treated with sand storage before spring sowing, that is, the seeds should be mixed with fine sand at 1:3 after harvest to maintain a certain humidity, buried outdoors, under the influence of low temperature in winter, and then take out and sow, the row spacing is 11.3 feet, the plant spacing is 0.7 feet, the covering soil is 2 minutes, and the sowing amount is 3 million taels per mu.
