1. How do you select sainfoin seeds?
Sainfoin seeds should be selected from those that are plump and healthy with no disease. It is best to use new seeds of the current year. The difference between old seeds should be fairly obvious, so they definitely cannot be used. Seed quality determines its germination rate and later growth, so you must buy high-quality seeds. There are many ways to buy sainfoin, but if you want to buy seeds with reliable quality, you need to choose carefully. It is best to buy from the local flower market or a seed company. The quality will be more guaranteed, and if there are any problems afterward, the seller can help solve them, and the after-sales service will be more comprehensive and complete.
2. Seedling-raising methods for sainfoin
1. Soil treatment
Sainfoin has no strict requirements for soil and no special requirements for the previous crop. In autumn, plow 20-25 cm deep to eliminate large clods and compacted root clumps. The following spring, level it with a notched harrow and a disc harrow. Complete the pre-sowing land preparation work.
2. Seed treatment
(1) Chemical treatment
Soak the seeds in 30% hydrogen peroxide for 15 seconds, which can increase the germination rate of the seeds.
(2) High-temperature seed soaking
Soak sainfoin seeds in warm water at 50°C for 6 hours, which can enhance the germination rate of the seeds.
3. Sowing method
In early to mid-April in spring, after the surface soil thaws, you can sow while preserving soil moisture. Use a seeder for drilling, with a row spacing of 20-30 cm, sowing depth of 3-5 cm, and sowing rate of 5-7.5 kg per 667 sq m. After sowing, they germinate in 3-4 days and emerge in 6-7 days. If there are missing-seedling areas, reseed in time.
4. Seedling-stage management
During the seedling stage, sainfoin plants are slender and weak with shallow roots, and strict management is required from emergence to the branching stage. Attention should be paid to water supply during the growth period. To ensure that sainfoin overwinters safely and turns green the following year, irrigate once in winter just before freezing.
Alright, that is all the content the editor wants to share with you.
