Breeding technology

Eichhornia crassipes can be sown and propagated. The fruit is harvested after ripening in autumn, the peel is cracked after drying, and the seeds are collected and dried. In January of the following year, the seeds were soaked in 30 ℃ warm water for 24 hours, stored in the dark place of wet sand, and germinated under 20-25 ℃ light in the middle of March. After the radicle appeared, the seeds could be sowed. Generally, strip sowing, row spacing 35cm, plant spacing 3~5cm, soil cover thickness 2~3cm and sowing amount 15kg/m2 are adopted.

The selected excellent individual plant can be propagated by grafting, and the rootstock is generally selected as silk cotton wood. When the rootstock germinates in the middle and late March, it can be grafted by split grafting and cutting. Shaanxi Weimao bonsai cultivated by high stem grafting has high ornamental value. Some seedling bases have successfully cultivated a large number of high-quality seedlings after years of exploration and selection of superior rootstocks and improvement of grafting techniques.

Many research institutions have also done a lot of research on the in vitro culture of Euphorbia angustifolia, using young stems and leaves as explants to induce callus, further differentiate into adventitious buds, induce roots in the later stage, and initially establish a regeneration system. However, large-scale production has not been achieved and is still being explored.

Cultivation and maintenance

Shaanxi Weimao is resistant to cold, drought, salt and alkali, strong adaptability, not affected by the acidity and alkalinity of the soil, simple and extensive maintenance and management, but it is often necessary to keep the soil moist and loose, topdressing 2 times a year.
