Types and cultivation methods of goldfish grass

1. The type of goldfish grass

There are many types of goldfish grass, which types can be divided into generally? There are hundreds of varieties of goldfish grass (leading flower), which can be divided into two categories: the original goldfish type and the newly cultivated bell type. The upper and lower lip flaps of the bell shape do not close, and the lip flaps open upward. According to the height of the plant, it can be divided into three categories: high seedling species (plant height 90cm 120cm, late flowering, long flowering period), middle seedling species (plant height 40cm 60cm, middle flowering) and dwarf seedlings (plant height 15cm 25cm, early flowering).

two。 Cultivation methods of Artemisia frutescens

Most of the original varieties of goldfish grass in China are cultivated for biennial flowers. In the north, the seeds should be sown in late August and emerge in about 10 days. Before winter, the seedlings should be pseudo-planted in a low-temperature greenhouse or cold bed, planted in an outdoor flower bed after the late frost next year, and bloom from June to July. It can also be sown indoors in early spring and blossom from September to October. The provinces in the south of the Yangtze River can spend the winter in the open field after autumn sowing and blossom from April to May next year.

The bell-shaped goldfish introduced from abroad not only has a large flower shape, a large number of flowers, but also a long flowering period, which is mostly used to produce fresh cut flowers for winter sale. The seeds should be sowed in the open field nursery bed in late summer and early autumn, planted in the open field seedbed first, and then moved to the greenhouse after autumn. It should be kept at 22 °C during the day and not less than 10 °C at night. New Year's Day can blossom before and after.

In order to increase the number of flower branches, the varieties of high and medium seedlings should be coring. In order to prevent the mixing of varieties caused by hybridization, the remaining plants of different varieties should be planted over a long distance.
