Problems solved by technology

However, since 2007, the hotan area of ​​Xinjiang has experienced continuous winter low temperature, which has caused the plantation of Cistanche tuberosum to be damaged almost every year, with an average loss of 50-60%, and the loss in the most serious year can reach more than 80%. In addition, after Cistanche was damaged by freezing, it rotted in place and polluted the soil, which had a great impact on the survival rate of inoculation in the later period, resulting in a 40%-50% reduction in the survival rate of inoculation at the same site in the later period. The survival rate has been reduced by more than 70%, which has greatly affected the enthusiasm of growers for planting

Embodiment 1

[0025] The method described in the present invention is carried out in the Cistanche plantation (N37 ° 01′ 37.4″, E80 ° 23′ 21.5″) in Baishituoglake Township, Lop County, Hotan District, Xinjiang. The garden is located in the southwest edge of the Tarim Basin and has a typical Dry continental climate characteristics. The climate is dry and rainless, with large evaporation, hot summer, cold but not cold winter, rapid and unstable temperature rise in spring, fast and short fall in autumn, large temperature difference between day and night, and long frost-free period. Specific steps are as follows:

[0026] According to the investigation, the average frozen soil depth in Luopu County over the years was 67cm, and the inoculation depth was determined to be 70cm. The inoculation was carried out at the end of March by using the method of dipping the roots with seed pulp. Gloss, use a 30-mesh (0.5mm) sieve to sort Cistanche seeds, keep the seeds with a particle size of 0.5mm, and the...

Embodiment 2

[0036] The method described in the present invention artificially planted tamarisk forests in Segezikule Township, Hetian County. The coordinates are 37°30′22.9″ north latitude and 79°58′26.2″ east longitude. It has typical arid continental climate characteristics, and the climate is dry and lacks rain. , large evaporation, hot summer, cold but not cold winter, fast and unstable spring temperature rise, fast and short fall temperature in autumn, large temperature difference between day and night, long frost-free period, annual average temperature of 12.8 ℃, maximum temperature of 40.6 ℃, minimum temperature of -21.6 ℃; the average daily temperature difference is 12.8 ℃, the annual temperature difference is 31.2 ℃, the accumulated temperature ≥ 10 ℃ is 4344.1 ℃, the total annual sunshine hours are 2643.9 hours, the sunshine percentage is 60%, the frost-free period is 226 days, the annual precipitation is 34.8 mm, and the evaporation is 2563.4 mm , with an average wind speed of 2...

Abstract

The invention relates to a comprehensive prevention and control method for the freezing injury of Cistanche tubulosa. According to the comprehensive prevention and control method, due to the fact that Cistanche tubulosa freezing injury prevention and control methods, such as the method for having control over inoculation depth, the method of hilling, the method of addition of coverings and the method of timely harvest are adopted, the degree of the freezing injury borne by the Cistanche tubulosa is reduced, the yield of the Cistanche tubulosa in the unit area is increased, income increase of Cistanche tubulosa growers can be promoted, stable and lasting development of ecological engineering is ensured, and industrialized and large-scale development of planting of the Cistanche tubulosa is promoted.

Description

technical field [0001] The invention belongs to the disaster prevention and control technology of traditional Chinese medicinal plants in Xinjiang's characteristic sand industry, and specifically relates to new technologies and methods for preventing winter freezing damage of Cistanche tubulosa by controlling inoculation depth, cultivating soil, and adding coverings. Background technique [0002] Cistanche tuberosum ( Cistanche tubulosa (Scgrenk) R.Wight), commonly known as Tamarix Dayun, belongs to the perennial parasitic herbaceous plant of Liedangaceae. is parasitic on Tamarix ( Tamarix ramosissima The precious medicinal material from the root of Ledeb). The most suitable living areas for Cistanche tubulosa are mainly distributed around the Tarim Basin in southern Xinjiang, eastern northern Xinjiang, and northwestern Gansu. Due to its good medicinal effect and high value, since the successful artificial inoculation of Tamarix was reported, the artificial planting of C...
