Problems solved by technology

[0004] The prior art is mainly aimed at the soft rot treatment methods proposed for carrots, konjac and green asparagus, etc., and makes targeted prevention and containment according to the characteristics of different crops, including the entire planting process or during transportation. The crops are treated with different soft rot pathogens, and the effect is remarkable, but there is no effective control method for pinellia virus disease and bacterial soft rot, so it is necessary to study a method to prevent or inhibit the soft rot of pinellia tubers occur

Embodiment 1

[0021] Every November, buy 50 kg of fresh, well-grown and evenly-sized pinellia tubers from the grower or cultivator, remove impurities, and buy wire mesh from the market to make sieves with 1 cm and 2 cm apertures. , Pinellia tubers are divided into three grades after sieving, those with a diameter greater than 2 cm are grade one, those between 1 and 2 cm are grade two, and those less than 1 cm are grade three, and the fresh weight M and M value of each grade are called It is 49.9 jin; the tubers after the grades are spread out for the first time to dry, and the thickness is 10 cm. During the first time to dry the tubers, turn the tubers every other day, and then weigh each level of dry weight m after the first time to dry, and the m value is 47.4 Calculate the difference between the fresh weight M and the dry weight m to be 2.5 kg, and then determine the water content through the ratio of the difference to the fresh weight M. The water content is 5%, and the net bag is store...

Embodiment 2

[0023] In October every year, 70 kg of pinellia tubers of this year are reserved for seeding, and impurities are removed. After sieving the tubers with 1 cm wire mesh, they are divided into two grades. Those with a diameter of 1-2 cm are grade one, and those below 1 cm are grade two. , called the fresh weight M of each level, the M value is 69.8 kg, after the initial drying of the seeds, the thickness is 12 cm, the tubers are turned every 2 days during the initial drying of the seeds, and the dry weight of each level is called m after the initial drying of the seeds, and the m value The water content of the tubers is 64.2 kg, and the calculated water content of the tubers is 8%. Accurate measurement of the water content of the tubers during the initial drying period is also an effective method for preventing soft rot. It can keep the water content of the tubers within the control range. The more water, the soft rot The incidence rate of the disease is also greater, after the in...

Embodiment 3

[0025]In mid-October every year, 150 kg of fresh, well-grown and uniform Pinellia tubers are purchased from growers or cultivators. Impurities are removed, and wire meshes with a sieve diameter of 1 cm and 2 cm are installed. Three grades, each grade weighs fresh weight M, and the M value is 148.9 kg. Those with a diameter greater than 2 cm are grade one, those with a diameter of 1 to 2 cm are grade two, and those with a diameter of less than 1 cm are grade three; Turn over the tubers every other day during the planting period, weigh each level of dry weight m after the first airing, the m value is 131.2 jin, the water content of the gained tubers is 12%, the initial airing thickness is 15 cm, and 6 pieces are stored in net bags During storage, check the water content of the tubers every 2 days to prevent the tubers from becoming moldy and rotten; remove the mechanically damaged tubers in April of the following year, then classify and soak the tubers in clear water to remove al...

Abstract

The invention discloses a treatment method for preventing soft rot disease of the tuber of pinellia ternate and belongs to the technical field of cultivation of traditional Chinese medicinal materials. The key point of the method is that a lot of seed stems are disinfected and sterilized before the seed stems of pinellia ternate are planted to prevent the soft rot disease so as to improve the planting yield of pinellia ternate and the quality of the tuber. The method mainly comprises the following steps: grading; primarily airing seeds; selecting seeds; sterilizing; immersing seeds; secondarily airing seeds; sterilizing the surface of the tuber of pinellia ternate; and then immersing seeds. The soft rot disease and spread of pathogen can be prevented, so that the planting yield and officinal quality of pinellia ternate can be improved. The method is simple and feasible, convenient to use and suitable for being popularized and applied to wide farmer households of pinellia ternate.

Description

technical field [0001] The invention belongs to the technical field of cultivation of Chinese medicinal materials, and in particular relates to a method for preventing pinellia soft rot from occurring by sterilizing tubers of pinellia before planting. Background technique [0002] Pinellia, also known as Pinellia three-leaf, is a perennial herb of the family Araceae. Pinellia is an important medicinal material in the treasure house of Chinese traditional medicine. It has been used in medicine for more than 2,000 years, and its origin is only in China and Japan in Asia. The medicinal function is to dry dampness and resolve phlegm, harmonize the stomach and stop vomiting. It can grow in most areas below the altitude of 2,500 meters in my country. It is mainly produced in 17 provinces and cities including Sichuan, Hubei, Henan, Guizhou, Anhui, Jiangsu, and Gansu. It grows in fields, streamsides, damp hillsides, and under forests. environment. In the first pinellia production,...
