Description

Technical Field

[0001] The invention relates to the technical field of Salsola guinea seedling cultivation, and in particular to a Salsola guinea seedling cultivation method. Background Art

[0002] Caroxylon passerinum (Bunge) Akhani & Roalson is a perennial semishrub of the Amaranthaceae family and the genus Caroxylon. It can grow up to 30 cm tall, with dense T-shaped hairs, old branches woody, gray-brown, and spreading; small branches herbaceous, yellow-green, with conical or triangular leaves, spike-shaped inflorescences, growing on the upper part of the branches, yellow-brown or light purple-red. The seeds grow horizontally or upright. It blooms from July to September and bears fruit from August to September. It grows on hillsides and gravelly beaches. It is drought-tolerant, resistant to wind and sand, and cold-resistant. It mainly grows in gray-brown desert soil on gravel ground and tolerates light salinization soil.

[0003] Pearlwood has a high dry matter content and a relatively stable crude protein content. It has good palatability and is the favorite food of camels and sheep in winter and spring, but is less popular with cattle and horses. It is the main feed or fattening feed for camels and sheep in winter and spring and drought years.
