Winter-sowing field seedling-growing method for haloxylon ammodendron

Abstract

The invention discloses a winter-sowing field seedling-growing method for haloxylon ammodendron. The method comprises the following steps: carrying out land preparation, ditching and bed preparation before seeding; collecting seeds, disinfecting and airing the seeds, mixing the seeds with dry sand in a mass ratio of 1 to 1, carrying out field row planting before the freezing of soil in November, covering earth, and irrigating sufficient winter water; carrying out thinning once in the last ten days of May or the front ten days of June, and carrying out secondary final singling and third final singling according to the growth conditions of seedlings; and carrying out after-planting management. According to the winter-sowing field seedling-growing method, haloxylon ammodendron seeds are directly sowed after being collected in winter, so that the germination rate of the seeds is increased, and the phenomenon that the germination rate is decreased due to improper storage is avoided; compared with a spring sowing manner, the winter sowing manner has the characteristics that the sowing is carried out before the freezing of soil, the underground parts grow first, the seeds can root deeply, the drought tolerance is strong, the nursery-grown plants can lignify earlier, and the drought tolerance and the disease resistance are relatively strong; the soil moisture status can be well treated; and in comparison with spring sowing, the emergence rate of the seeds can be increased, and the quality of nursery-grown plants can be improved.

Description

technical field [0001] The invention belongs to the field of plant seedling breeding and propagation, and in particular relates to a field seedling raising method of Haloxylon sowing in winter. Background technique [0002] Haloxylon ammodendron (C. A. Mey.), also known as Suo Suo, is a small semi-arbor of Haloxylon ammodendron (C. A. Mey.) in Chenopodiaceae, and is a sand-fixing plant that grows on sandy ground. Haloxylon is strong in drought resistance, heat resistance, cold resistance, and salt and alkali resistance. The salt content in the stems and branches is as high as about 15%. Strong, can improve the soil, restore vegetation, and protect the surrounding desertified grasslands. It is an excellent tree species for sand fixation and afforestation in the arid desert areas of Northwest my country and Inner Mongolia. The material of Haloxylon is heavy and brittle, with extremely strong burning power and less smoke. It is a high-quality fuel in the production area; Haloxy...
