In Northeast China, the Yellow River Basin provinces and northern Jiangsu, northwest China, Mongolia and Siberia. In short, the species has a wide distribution and a large change in morphology. The root bark is scarlet, and the general variation is the color of bracts and pupa. Some sepals are green, pink or white; some sepals are green and have red edges... In short, these changes are related to environmental conditions.
Third, nursery seeding:
Because dry plum is a unique wild plant in the North, domestication and cultivation time is not long, development and research has just started, many people do not grasp the cultivation techniques, coupled with tiny seeds, if exposed directly to the ground, often susceptible to wind, drought, soil quality, etc., will Difficult to emerge seedlings or seedlings, resulting in failure and economic losses, so the construction of the best growers to use seedlings to transplant planting is better, with the same method of vegetable seedlings, in fact, it is not difficult.
1, nursery method:
First of all, it is desirable to reconstruct the greenhouse seedlings. When the temperature reaches 18°C or more, the seedlings can be started. Select sandy land in the shed, start preparation for land preparation, sifting (screening clods, sand and other impurities), leveling and boring. After irrigating the water, start on-demand or broadcast, and then cover the soil with a sieve about 0.5 cm to keep the seedbed moist. Appropriate temperature, about 7 days to emerge, appropriate control of watering, appropriate air release, seedlings, seedlings to 5-7 cm began transplanting.
If there is no greenhouse, when the ambient temperature is 8-10°C on average, choose a lee place where the sun is sunny and the soil is good. Slot the seedbed, usually 30 cm (height) 100 cm (width) 40 cm (length), according to the greenhouse nursery. After sowing, cover with a film and cover the straw at night. At the same time, strong seedlings are also cultivated.
2. Transplanting method:
Dry branches Meiyi should be cultivated in sandy soils with good air permeability and good livelihood. When transplanting, flat land can be used for hoeing, and sloping land can be digged, and transplanting can be done according to local conditions in different regions, similar to the method of vegetable back-up.
The planting on the barren slopes does not require a complete site preparation. It is only necessary to dig a hole with a diameter of 30 cm and a depth of 15 cm. There are 8,000 ceiling-grown seedlings and 10,000 plants, depending on the fertility of the land and the number of plants. Planted in shallow pits and transplanted into the plant and watered immediately until the seedlings survived, allowing for extensive management.
3, management methods:
In the seedling stage requires careful management, timely fertilization, grass weeding, watering can be. By mid-term management, you can relax, and later picking.
4, picking time:
In the seedlings Mei is a perennial grass plant, when 25-30 cm in height, about 25 cm in diameter can be picked and sold, the general picking time is in the fall, after the seed is ripe, every year, do not damage the roots when harvesting, Cut from the root above 5 cm is appropriate, otherwise it will be dry and broken and wasted.
5, seed collection methods:
Seed-collecting time is autumn, and from September to October, most dry branches are mostly infertile. The amount of seed is very small. Only relying on the amount to harvest, until the seed matures, cut at 5 cm above the plant, focus on the sun, and plant seeds. .
