How to grow Astragalus for high yields? Detailed planting techniques
Astragalus is a legume plant. Astragalus holds a very important place in the medicinal herb world, especially in traditional Chinese medicine. Astragalus has the effects of promoting diuresis and reducing swelling, and tonifying qi and securing the exterior, and can be used in combination with many medicinal herbs. Today, Astragalus cultivation has been widely carried out, but some yields are not very ideal, so below Shuashuai will explain how to grow Astragalus for high yields!
I. Site selection and land preparation
To achieve high yields, the first step is to choose good land. For Astragalus planting, it is best to choose deep soil with good drainage. Before sowing, we need to improve the land. First, fertilize the land to increase fertility. Generally, concentrated fertilizer and phosphorus fertilizer are applied to ensure the nutrient content and fertility of the land after crop rotation.
II. Seed treatment
Astragalus seeds must be treated before sowing. First, we put the seeds into 50-degree warm water and stir, soaking for 24 hours. Then cover with a wet cloth, and sow after the seeds split open and sprout.
III. Sowing
Sowing is divided into several seasons, including spring sowing and autumn sowing. For sowing, first evenly scatter the seeds into the furrows, then cover with soil and seal the seeds firmly, and finally pour water into the furrows to keep the soil moist. Seedlings emerge after 15 days, but in this case there is a lot of disease.
IV. Cultivation management
Keep the spacing between each plant appropriate, and frequently weed the field so that weeds do not compete with Astragalus for nutrients. Weeding two to three times is enough. During this period, topdressing is also required. The fertilizer can be phosphorus fertilizer and ammonium sulfate, mixed and diluted with water, then poured on.
V. Pest and disease control
The main disease of Astragalus is powdery mildew, which can be controlled with thiophanate-methyl. Another is violet root rot, which harms the roots and causes Astragalus root rot. Once discovered, use lime powder for disinfection. If other pests are found, spray the corresponding insecticide.
The above are the high-yield Astragalus planting techniques. The editor suggests that when choosing land, do not choose crop fields that have been in rotation for several years. The quality of these fields is already very poor and not suitable for planting medicinal plants like this. If conditions permit, you can buy some fertile land or rent a site.
