A method for preventing and controlling freezing damage of Cistanche piculosum

Abstract

The invention relates to a method for preventing and controlling the freeze injury of cistanche tubulosa R.Wight. The method comprises the following steps: inoculating cistanche tubulosa R.Wight in autumn, inoculating in next autumn, digging a heat-preserving gully in the outer side of a position 10-20cm away from an inoculation gully, wherein the heat-preserving gully is an inclined gully inclined from a gully cut and a gully bottom, and the vertical depth of the heat-preserving gully is 50-70cm; and carrying out mechanical punning on the upper side and lateral side, close to the tamarix ramosissima side, of the heat-preserving gully. According to the invention, due to the arrangement of the heat-preserving gully, and according to the position, depth and width of the heat-preserving gully, the solar irradiation area is increased, and the evaporation of soil moisture is accelerated, so that the soil moisture content of a cistanche tubulosa R.Wight inoculation area is reduced, and the soil temperature of the cistanche tubulosa R.Wight inoculation area is increased. With the reduction of the soil moisture content of the cistanche tubulosa R.Wight inoculation area and the increasing of the soil temperature of the cistanche tubulosa R.Wight inoculation area, the depth of a frozen soil layer in winter is reduced, thereby preventing the freeze injury of cistanche tubulosa R.Wight caused by low temperature.

Description

technical field [0001] The invention relates to a method for preventing and controlling freezing damage of Cistanche tubulosa, belonging to the field of plant disaster prevention and control. Background technique [0002] Cistanche tubulosa (Cistanche tubulosa R.Wight) is an obligate parasitic plant parasitic on the roots of tamarisk. , Traditionally used for essence and blood deficiency, deficiency of kidney yang, weakness of muscles and bones, weakness of waist and knees, impotence and infertility, dryness of the intestine and constipation. Modern research shows that Cistanche has various functions such as improving learning and memory ability, improving sexual function, anti-senile dementia and Parkinson's disease, anti-aging, protecting liver, anti-fatigue, and laxative. It is widely used in clinical prescriptions of traditional Chinese medicine and health care products and Chinese patent medicines. Due to its wide range of uses, long-term random digging and special br...

Problems solved by technology

[0004] Chinese patent document CN103875407A discloses a method for comprehensive prevention and control of frost damage of Cistanche tubulosa, which uses measures such as controlling the inoculation depth, cultivating soil, adding mulch, and timely harvesting to prevent and control the freezing damage of Cistanche tubulosa, thereby reducing the degree of freezing damage of Cistanche tubulosa in winter , improve the output of Cistanche deserticola per unit area, the method is cumbersome to operate, the cost is high, and the efficiency is low (because the method is only suitable for manual operation and cannot be used for mechanized operations)

Although this method has a certain prevention and control effect on Cistanche deserticola freezing damage, it has not fundamentally solved the problem of freezing damage to Cistanche deserticola.

The main reason why this method cannot completely prevent and control the freezing damage of Cistanche tubulosa is that the use of soil and mulch increases the ground temperature while increasing the soil moisture content.
