The latest course of planting techniques and methods of Ulmus pumila

Sanguisorba officinalis L. is a perennial herb of Rosaceae. It is a traditional Chinese medicine in China and has a wide distribution. Sanguisorba's tender stems and flower ears can be used for frying, cooking, etc., with various effects such as hemostasis, cooling blood, clearing heat and detoxification, and also has certain ornamental. So how do you plant garden burnet? The following small series brings you the planting technology of garden burnet. Let's take a look together!

1. Seed picking and soaking

The end of September is the best time to harvest the seeds of Sanguisorba officinalis L. at this time, the yield of Sanguisorba officinalis L. seeds is high, and the quality can be guaranteed to some extent. Sanguisorba has strong adaptability and seeds are not easy to fall off, so it is also possible to delay the harvest time to about October to improve the germination rate of seeds. After seed collection, treat the seeds, do a good job of soaking and disinfection, choose warm water when soaking seeds, but the temperature should not be too high, otherwise it may lead to scalding of seeds. Attention should be paid to the use of disinfectants to prevent excessive disinfection and affect seed germination.

2. Timely sowing

After processing seeds, select sandy soil with sufficient light and fertility, then prepare the soil and make deep ploughing, and apply sufficient base fertilizer. Control the sowing density and sow it evenly in the soil. After sowing, cover it with fine soil, press it properly and irrigate enough water. When there is no germination, it is necessary to ensure that the soil is wet enough, and the soil temperature is controlled at about 18 degrees to prevent the temperature from being too low to affect the germination of garden burnet seeds. Generally, it can emerge in 3 weeks. After emergence, management should be strengthened to ensure the healthy growth of garden burnet seedlings and create a good growth environment for seedlings.

3. Field management

Sanguisorba's growth ability is relatively strong, so field management can be relaxed appropriately. However, lower than the water demand is relatively large, so in planting to keep the soil moist, often watering. And to appropriate topdressing, topdressing control the use of nitrogen fertilizer, mainly decomposed farm manure. Every harvest needs topdressing once, restore the growth of Sanguisorba, promote leaf growth, delay bolting of Sanguisorba. If the planting direction is young leaves, then in the plant bolting time to remove flowers, promote the growth of new leaves. Finally, we should do a good job of intertillage and weeding to prevent weeds from robbing the growth of Sanguisorba.

4. Pest control

The incidence of diseases and insect pests of garden burnet is relatively low, because the growth ability of garden burnet is strong, but in the case of poor management. There will still be some diseases and insect pests, such as powdery mildew, scarab and so on. Therefore, we should also do a good job in the prevention and control of diseases and insect pests, often weeding, controlling planting density, preventing over-dense planting and reducing field permeability. It is necessary to ensure that Sanguisorba absorbs sufficient light to prevent excessive humidity in the field. Regularly observe the growth situation, and timely take corresponding measures when symptoms are found to prevent the spread of the disease.

The above is a simple introduction to the planting technology of Sanguisorba. The planting technology of Sanguisorba is relatively simple, and it is not so troublesome to manage. However, we still need to do basic work, otherwise it will have a certain impact on Sanguisorba. Today's introduction is here, this article is for reference only, thank you for reading and support.
