Embodiment 1

[0018] (1) Preparation of covering matrix

[0019] Harvest the Artemisia annua plants 10 days before flowering, put them in the shade to dry for 3 days, cut them into small pieces of 12-15cm, and divide the small pieces of Artemisia annua, pine needles and decomposed bark into Artemisia annua: Pine needles: Decomposed bark The mass ratio is 1:1.5:2 and the ratio is mixed to form the covering matrix;

[0020] (2) Cover the surface of the soil where Panax notoginseng is planted with the covering substrate prepared in step (1), spread out and water.

Embodiment 2

[0022] Embodiment 2 except that following measures are different, all the other measures are identical with embodiment 1.

[0023] (1) Preparation of covering matrix

[0024] Harvest the Artemisia annua plants 15 days before flowering, put them in the shade to dry for 5 days, cut them into small pieces of 12-15cm, and divide the small pieces of Artemisia annua, pine needles and decomposed bark into Artemisia annua: pine needles: decomposed bark The mass ratio of the mixture is 1.5:1:3 and the mixture is evenly mixed to form the covering matrix.

[0025] Control: the control is to mix the pine needles and decomposed bark according to the mass ratio of pine needles: decomposed bark of 1.5:2 to form the control covering substrate, cover the reference covering substrate on the soil surface of Panax notoginseng, spread it and water it .

Abstract

The invention discloses a method for inhibiting panax notoginseng from root rot by a cover matrix. The method comprises the steps: harvesting artemisia annua plants 10-15 days before flowering, putting the harvested artemisia annua plants at a shady place for air-curing, chopping the artemisia annua plants into small segments, and uniformly mixing the chopped small artemisia annua segments, pine needles and well-composted bark in accordance with that the mass ratio of the artemisia annua to the pine needles to the well-composted bark is (1-1.5): (1-1.5): (2-3), so as to prepare the cover matrix; and covering the surface of soil for planting the panax notoginseng with the cover matrix, and carrying out flattening and watering. According to the method disclosed by the invention, the growth of the panax notoginseng can be promoted, the yield of the panax notoginseng can be greatly increased, and the occurrence of the panax notoginseng root rot of a panax notoginseng planting land block can be greatly inhibited. According to the method disclosed by the invention, the prevention and control effect on the panax notoginseng root rot reaches 73.2% or more, and the panax notoginseng product is free of pesticide residue. Compared with the control, the root dry weight of the produced panax notoginseng is increased by 22.82% to 29.13%.

Description

technical field [0001] The invention belongs to the technical field of plant protection, and particularly relates to a method for suppressing root rot of Panax notoginseng by covering the substrate containing Artemisia annua on the surface of Panax notoginseng planting. Background technique [0002] Panax notoginseng (Burk.) F.H.Chen, also known as Tianqi, is a perennial herbaceous plant of the Araliaceae genus Ginseng. It is a kind of plant with strict requirements on environmental conditions among medicinal plants, and it likes warmth and humidity. Its unique ecological environment can easily induce various diseases, among which root rot is the most serious. In the production of Panax notoginseng, the so-called root rot can include a variety of different disease manifestations, including yellow rot, dry cracking, pith rot, wet rot, dry stem base and acute bacterial wilt, etc. Among them, the most common type is the "yellow rot type", which can occur in every year of Panax...
