The Latest Field Management Methods and Technical Points for Solomon's Seal
Solomon's seal is a documented traditional Chinese medicinal herb in our country, and it is widely used in many places and industries. As the annual sales of Solomon's seal increase, the wild population of Solomon's seal is continuously decreasing. Therefore, the area of artificial cultivation is gradually expanding. When planting Solomon's seal, if you want to increase the yield, you must do a good job in management. So today, the editor has brought you the field management methods for Solomon's seal. Let's take a look below!
1. Seedling emergence management
During the period from planting the seed stems to seedling emergence, we should frequently inspect the field conditions. If there is a shortage of mulch, it must be replenished in time, and attention should be paid to keeping the soil moist to promote germination and seedling emergence. When the seed stems emerge, the mulch on the bed surface should be removed in time to avoid obstructing the seedlings from pushing through the soil, affecting the emergence rate, and causing injury to the seedlings. If the mulch is pine needles, then a relatively thin layer can be retained. This can not only improve the soil's moisture retention capacity, but also inhibit weed growth and reduce the cost of manual cultivation.
2. Proper thinning of seedlings
After the seedlings emerge, management and inspection should be strengthened. During the growth of the seedlings, we should do a good job in thinning according to the emergence rate and the growth conditions of the seedlings. When the seedlings grow to about 9 cm tall, if they are too densely grown, they should be thinned in time. Thinning follows the principle of keeping the strong and removing the weak, providing sufficient growth space for robust seedlings. Then we should also do a good job in weeding, especially during the seedling stage. Too many weeds will lead to poor nutrition for seedling growth, so weeds should be pulled as soon as they are seen. Try to avoid using a hoe to prevent damage to the seedling roots. When the soil is dry, pull by hand; after rain or when the soil is moist, weeding should be stopped.
3. Water and fertilizer management
Topdressing for Solomon's seal is very important. When planting, we should reasonably adjust the fertilization method according to the number of years of seedling cultivation. If the seedling cultivation period is one year, then on the premise of applying sufficient base fertilizer, basically no fertilization is needed. If the seedling cultivation period is two years, then generally after the aboveground plants wither, an appropriate amount of organic fertilizer should be applied in early winter, with the amount controlled at 2000 kg/mu. During the seedling stage, attention should also be paid to watering. When the soil is dry, water in time. However, it should not be too much, and drainage should also be done well during the rainy season.
4. Shading and cold protection
Although the growth of Solomon's seal requires a certain amount of light, it is very sensitive to light intensity. Therefore, when planting Solomon's seal, we should pay attention to doing a good job in shading. We can plant some tall-stalked crops such as corn beside the beds to provide shade for Solomon's seal, or build a shade shed after the Solomon's seal seedlings emerge. Then, after the one-year-old seedlings wither and before the soil freezes, cover the soil with some leaves, rice straw, etc. This improves the soil's heat preservation capacity and promotes the overwintering of Solomon's seal seedlings.
The above is a brief introduction to the field management methods for Solomon's seal. The management work for Solomon's seal is very important and has a direct impact on yield, so everyone must pay close attention. That is all for today's introduction.
