Description

A kind of cultivation method of spring wheat interplanting Bupleuri

technical field

The invention relates to a cultivation method for interplanting Bupleurum bupleurum with spring wheat, which is especially suitable for cultivation in eastern Hebei (for example: Tangshan, Hebei), and belongs to the technical field of plant cultivation.

Background technique

Bupleurum chinense DC., also known as Bei Bupleurum, is a perennial herb of Umbelliferae. Its roots are used as medicine. Malaria, hypochondrium pain and other diseases. Modern pharmacological studies have proved that Bupleurum bupleurum also has antipyretic, sedative, antibacterial and antiviral effects. Bupleurum bupleurum is widely used clinically, and it is a commonly used variety of traditional Chinese medicinal materials in my country. It is mainly produced in Shanxi, Shaanxi, Hebei, Gansu and other places. Bupleurum originally grows in relatively dry hillside areas, prefers a cool climate, and is resistant to drought. It is suitable for growing in an environment with long light time, large temperature difference between day and night, hot summer and cold winter. It likes a cool and humid climate. It is not resistant to high temperature and has strong cold resistance and drought resistance. Bupleurum bupleurum prefers shade during the germination and seedling stages, and adult plants need sufficient sunlight for growth. The plants of the current year seldom bloom, and the fleshy roots and seeds are generally harvested in the second year. Biennial seeds can be harvested for planting the following year. The artificial cultivation of Bupleurum is mostly based on seed propagation, but the seeds of Bupleurum are small in size, short in life, inconsistent in seed maturity, with an average germination rate of less than 35%, and the life of seeds stored at room temperature does not exceed one year. It takes 50 to 80 days from sowing to germination under suitable conditions, so it is difficult to ensure that all seedlings are sown at once, which seriously restricts the improvement of Bupleurum planting benefits.

At present, there is no interplanting technology of Bupleurum and wheat. If the measures are not taken properly, not only the wheat will not be planted well after interplanting, but also the quality and yield of Bupleurum will be affected, resulting in waste of land resources and poor economic benefits.

Topdressing: combined with watering three times, topdressing urea 10-15 kg per mu;

Watering: After the second internode is finalized, after the death of invalid tillers, water three more times, irrigate enough and thoroughly;

4.3 Management of blooming mature period

Topdressing: Spray 200 grams of potassium dihydrogen phosphate and 200 grams of urea per mu on the foliage from flowering to filling period, once; to prolong the filling period and increase yield;

Watering: water the wheat for the fourth time after flowering, and water again after an interval of 15 days to ensure the needs of flowering, fertilization, and grouting in the later stage; pay attention to not watering in rainy and windy days during the grouting period to prevent lodging;

4.4 Heading stage management

After the earing of wheat, the center of gravity rises, the lodging resistance is weakened, and improper watering can easily cause lodging; therefore, water after earing should not be too large, and do not water in windy days;

5 Spring Wheat Harvest

In early and mid-July of the first year, the wheat is harvested after it enters the wax ripening period, and 10cm of stubble is left after mechanical harvesting; in addition, the wheat harvesting season coincides with the rainy season, so wheat harvesting should be promptly harvested and threshed;

6 Bupleurum varieties to choose from
