Problems solved by technology

However, the large-scale cultivation of Jintiesuo has been plagued by diseases and weeds, which cannot solve the problem of increasing shortage of commercial raw materials. Among them, root rot is an important factor affecting the production of Jintiesuo
[0003] A lot of researches have been done on the occurrence and control of Jintiesuo root rot, but it is still impossible to control the large-scale outbreak of Jintiesuo root rot. Most growers began to have a large area of ​​Jintiesuo root rot after the second year of planting. The phenomenon of withered and dead seedlings has caused huge economic losses to farmers
The prevention and control of root rot disease traditionally adopts two methods of agricultural technology control and pesticide control, but the medicinal properties of Jintiesuo determine that the prevention and control of root rot disease cannot be solved by agricultural technology alone.
The existing prevention and treatment technology for root rot of rhizome plants after the onset of the root rot is ineffective for the root rot of the golden iron lock. There is no effective technology for the prevention and treatment of the root rot of the golden iron lock at home and abroad so far, so it is necessary to study a set of prevention and control methods for the root rot of the golden iron lock

Embodiment 1

[0020] A method for preventing and treating root rot of golden iron lock, the method may further comprise the steps:

[0021] (1) Land preparation, before seed treatment, on the basis of leveling the moisture surface and finely crushing the soil, first spray the land with 98% Dasweep wettable powder at an application rate of 20g / ㎡, and cover it with plastic film after spraying The soil is fumigated for 7-10 weeks, and after disinfection, the film is removed and the poison is released for 20-25 days;

[0022] (2) Seed dressing, choose the plump, disease-free seeds of the three-year-old Jintiesuo or the robust, disease-free annual Jintiesuo seedlings, after the Jintiesuo seeds are soaked in normal temperature water, remove the floating immature seeds and impurities, The plump seeds after purification are seed-dressed with a seed-dressing agent, and the dosage of the seed-dressing agent is 0.5% of the seed mass and 0.3% of the seedling mass for seed-dressing and seedling-dressing...

Abstract

The invention discloses a method for preventing the radix psammosilenes root rot disease. Seed dressing or seedling dressing is carried out on seeds or seedlings through a seed dressing agent, and then planting is carried out through a soil fumigation method. The seed dressing agent is prepared from gibberellin, thiram, bismerthiazol and a sterilizing agent. The sterilizing agent is any one of carbendazim and Lvheng No.1. The proportion of substances of gibberellin, thiram, bismerthiazol and the sterilizing agent in the seed dressing agent is (1-3):(1-2):(2-4):(1-3). The seed dressing agent is adopted for seed dressing or seedling dressing of the seeds or the seedlings, and then planting is carried out through the soil fumigation method so that germs and weed in soil can be thoroughly killed, soil activity is stimulated, besides, the application amount of fertilizer and pesticide is reduced, prevention of the radix psammosilenes root rot disease is more scientific and efficient, occurrence and spread of the radix psammosilenes root rot disease can be controlled, cost is reduced, the prevention effect is improved, the quality of radix psammosilenes is improved, the yield of radix psammosilenes is increased, and the aim of increasing income of farmer households is achieved.

Description

technical field [0001] The invention relates to the field of planting Chinese herbal medicines, in particular to a method for preventing and treating root rot of jintiesuo. Background technique [0002] Jin Tiesuo is a rare and endangered plant of a single species unique to Southwest China, and Lijiang is its origin. Jintiesuo is the main raw material of Yunnan Baiyao, Bitongning and other nationally protected famous prescriptions. Modern pharmacological research has proved that Jintiesuo also has the effect of detoxification and is a booster for various vaccines. However, the large-scale planting of Jintiesuo has been plagued by diseases and weeds, which cannot solve the problem of increasing shortage of commercial raw materials. Among them, root rot is an important factor affecting the production of Jintiesuo. [0003] A lot of researches have been done on the occurrence and control of Jintiesuo root rot, but it is still impossible to control the large-scale outbreak of J...
