Seedling raising method of soil and water conservation plant artemisia brachyloba

Abstract

The invention discloses a seedling raising method of soil and water conservation plant artemisia brachyloba, which relates to a seedling raising method. The implementation method comprises the following steps: (1) raising seedlings by using a polystyrene foam box; (2) preparing a plastic tray according to the size of the foam box; (3) preparing the soil: using soil in a depth of 0 to 30 cm on thesurface of farmland; (4) preparing seeds: collecting the seeds, removing outer involucral bracts of seeds, sieving, and collecting the seeds; (5) boxing the soil, and placing on a tray; (6) watering;(8) covering soil: screening the soil to obtain 40-mesh to 80-mesh fine soil in a thickness of 1 to 2 mm; (9) shading; (10) managing at a seedling stage; (11) separating the seedlings: dividing one foam box of seedlings into two foam boxes of seedlings; (12) managing at an adult seedling stage; and (13) transplanting the artemisia brachyloba seedlings into a greenhouse in winter, and transplantingwith soil lumps in the rainy season of the following year. The water retention and moisture retention effect is good, the phenomenon that artemisia brachyloba seedlings fall and die because the seedlings are too small can be avoided, the seedlings are convenient to move, and the survival rate of the seedlings is improved.

Description

technical field [0001] The invention relates to a method for raising seedlings, in particular to a method for raising seedlings of the water-conserving plant Artemisia annua with small seeds and seedlings which are easy to lodging. Background technique [0002] Artemisia annua is a semi-shrub plant, which is common in the southwest of Xing’an League, Inner Mongolia Autonomous Region. The topography of this area is characterized by “northern mountains, middle hills, and southern plains”. The northern mountainous area accounts for 33.1%, and the central low mountain rocky hills account for To 39%, it belongs to the temperate continental monsoon climate, the annual average temperature is 5.7 ℃, and the average precipitation is less than 400 mm, and it is concentrated in June-September, so the plant growth conditions are relatively poor. In some areas, such as some mountainous areas in Tuquan County, there is only Artemisia annua, and other plants have little ability to survive ...

Problems solved by technology

However, floating seedlings are better for aquatic and mesophytic plants. For xerophytic plants, using this method is not conducive to their growth.

The second method is to grow seedlings in seedling trays, such as a Chinese patent for a special controlled-release fertilizer for tobacco seedling raising trays and its preparation method (patent number is ZL201410312103.1). The seedling trays have 21 holes, 32 holes, 50 holes, 72 holes, 200 holes, etc., the length of the tray is 54cm, the width is 28cm, and the depth of the hole is 4-9.5cm. Quick-drying, it is not easy to manage at the seedling stage, if the temperature is high and the soil temperature is high, it is easy to scald the seedlings and even die

If you water frequently in hot weather, the workload will be increased

At the same time, the frequency of watering is too high, it is easy to make the Artemisia annua seedlings fall down and die

The third method is live broadcasting. Watering live seedlings can easily cause them to fall and die, resulting in a low survival rate.
