Embodiment Construction

[0024] Planting method of selenium-enriched and high-yield milk vetch:

[0025] 1. The early, middle and late varieties are planted in a ratio of 2:5:3. That is, early-maturing varieties account for 20% of the sown area, mid-maturing varieties account for 50% of the sown area, and late-maturing varieties account for 30% of the sown area, extending the picking period of terminal buds and flower buds.

[0026] 2. Sowing on September 10-20: interplanting of single-season rice stubble on September 10-15, and interplanting of double-cropping rice stubble on September 15-20.

[0027] 3. Strengthen field management, plant seeds in wet fields, germinate in tidal fields, open three ditches, and do a good job of clearing ditches and drainage in time;

[0028] 4. Before winter comes, about before December 20, return 200 kilograms of rice straw per mu to cover the field evenly, and apply 1,000 kilograms of soil fertilizer and farmyard manure per mu. It not only plays the role of moistur...

Abstract

The present invention features the high-yield plantation of selenium-rich Astragalus sinicus. Seeds of early, middle and late stage varieties in the ratio of 2 to 5 to 3 are matched in planting so as to prolong the picking period of terminal flush and bud; and in the early stage of production, sodium selenite is foliage applied. The selenium-rich Astragalus sinicus may be produced into Astragalus sinicus stem and leaf tea and Astragalus sinicus flower tea, and this can raise the economic value of Astragalus sinicus. In addition, selenium-rich Astragalus sinicus may be further produced into other selenium-rich products with health care function.

Description

Technical field: [0001] The invention relates to a planting method of milk vetch and its comprehensive utilization. Background technique: [0002] Developing the production of organic fertilizers and reducing the application of chemical fertilizers and pesticides is one of the main measures to improve the quality of agricultural products. As the main source of organic fertilizer, the green manure species milk vetch once played an important role in agricultural production. But for a long time, milk vetch has only been used as a single way of green manure, and it has been greatly impacted by chemical fertilizers. Its economic benefits are low, and the planting area continues to decrease, resulting in the continuous increase in the amount of chemical fertilizers used in crops and the decline in the quality of agricultural products. It is expected that by increasing the economic value of milk vetch as an organic fertilizer source, the production of milk vetch will be expanded, ...
