The disadvantage is that the distribution of dripping water is uneven, the evaporation is unstable, which affects the distribution of moisture, thereby affecting the emergence rate (germination rate)
The emergence is slow and the emergence period is long, and it takes 10-15 days to complete the emergence; dry sowing dripping is to sow Astragalus directly in dry soil, and use a drip irrigation pipe to drip water to 5 cm below the soil on the day of sowing; the disadvantage is that the dripping water is unevenly distributed, Evaporation is unstable, which affects the distribution of moisture, thereby affecting the emergence rate (germination rate)
The emergence is slow, the emergence period is long, and it takes 10-15 days to complete the emergence

Embodiment Construction
[0015] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0016] The method for raising seedlings of Radix Astragali covered with film, comprises the steps:
[0017] S1. Dry sowing: Sowing Astragalus membranaceus directly in dry soil, and laying drip irrigation pipes at the same time;
[0018] S2. Mulching film: Mulching the soil that has been sown astragalus membranaceus;
[0019] S3. Drip water: After the sowing and film covering are completed, drip water on the film-covered seeding area on the same day to 3-5 cm below the soil; then drip water every three days, 3-5 cm each time;
[0020] S...

Abstract
The invention discloses an astragalus membranaceus film mulching sowing and seedling raising method. The method comprises the following steps of S1, dry sowing; S2, film mulching; S3, water dripping; and S4, film uncovering. After astragalus membranaceus is subjected to film mulching, sowing and seedling raising, water dripping operation can be effectively carried out on a sowing area, the soil moisture evaporation amount is reduced, it is guaranteed that soil moisture can be effectively utilized by vegetation, and it is guaranteed that the soil moisture content is stable. The mulching film has a heat preservation effect, so that the sprouted seedlings are thicker and stronger. Meanwhile, the seedling emergence time can be shortened, seedlings can emerge within 7 days at the soonest, and the seeding efficiency is greatly improved.
Description
Technical field: [0001] The invention relates to a film-covered sowing and seedling raising method of Astragalus membranaceus, belonging to the field of sowing and seedling raising of Astragalus membranaceus. Background technique: [0002] Astragalus, also known as Astragalus, is a perennial herb with a height of 50-100 cm. The main root is thick, woody, often branched, off-white. The stem is erect, the upper part is much branched, has fine ribs, and is covered with white pilose.
