Problems solved by technology

However, pathogenic bacteria are the dominant factor, and the wounds caused by underground pests are conducive to the invasion of pathogens, which leads to the aggravation of the disease and is the cause of the disease.
[0003] In recent years, the harm of potato nematodes has led to a large reduction in yield and quality of Angelica sinensis
According to the experimental research, the incidence rate of hemorrhoids will reach more than 80% in the plots planted with angelica year after year, the yield is only 6390kg / hm2, the yield rate of super-grade angelica is only about 5%, and the yield rate of first-class angelica is only 28%. %, the yield rate of second-, third- and second-class angelica is as high as 67.0%; and the timely disease control and careful management of returning to the field, the field incidence rate of angelica sputum is only 14.2%, and the yield is 14307kg / hm2, super-class angelica The yield rate is as high as 34.5%; the yield rate of first-class angelica is 29.3%, and the yield rate of second-, third- and second-class angelica is 36.2%. It can be seen that diseases not only affect the yield of angelica, but also affect the quality of angelica

example 1

[0017] (1) Cultivation The selected planting fields should be rotated with wheat, beans, and rapeseed for more than three years. If there is no crop rotation or the rotation period is less than three years, the soil should be plowed by 20cm; When fertilizing, apply 80kg per mu;

[0018] (2) Soil treatment Soil treatment is carried out before raising seedlings, mix well with 6 kg of 95% Cotton Long plus 40 kg of fine soil, sprinkle on the ground, turn 20 cm into the soil, loosen the soil and sow after 20 days; use it before planting seedlings in Angelica field 2.5% metalaxyl, mixed with fine soil at 3 kg / mu, sprinkled on the ground, and poured into the soil;

[0019] (3) Soak the seedlings of Angelica sinensis seedlings before planting with azoxystrobin 1000 times liquid to dip the roots for 30 minutes, dry them and plant them; minimize the root trauma of Angelica sinensis during seedling raising, seedling raising and cultivation management;

[0022] (1) Cultivation The selected planting fields should be rotated with wheat, beans, and rapeseed for more than three years. If there is no crop rotation or the rotation period is less than three years, the soil should be plowed by 15cm; When fertilizing, apply 120kg per mu;

[0023] (2) Soil treatment Soil treatment is carried out before raising seedlings, mix well with 6 kg of 95% Cotton Long plus 40 kg of fine soil, sprinkle on the ground, turn 20 cm into the soil, loosen the soil and sow after 20 days; use it before planting seedlings in Angelica field 1.8% diniconazole spraying planting ditch;

[0024] (3) Difenoconazole 1000 times of difenoconazole 1000 times liquid before planting and dipping the roots for 30 minutes, then planting after drying; minimize the root trauma of Angelica sinensis during seedling raising, seedling raising and cultivation management;

Abstract

The invention relates to the technical field of Chinese herbal medicine disease control and pesticides and specifically relates to a control method for angelica sinensis ditylenchus destructor thorne. The method comprises the steps of (1) cultivation, (2) soil treatment, (3) seedling soaking, and (4) pesticide control. The method employs low-toxicity and low-residue pesticide control, and thus reduces the residue quantity of pesticides, and guarantees production of safe angelica sinensis; control is performed in the soil treatment, seedling soaking and growing periods and different kinds of pesticides are applied in the different phases, so that drug resistance is prevented; the input cost is reduced and the yield is increased.

Description

technical field [0001] The invention relates to the technical field of Chinese herbal medicine disease prevention and control and pesticides, in particular to a method for prevention and treatment of angelica rhizome. Background technique [0002] Angelica pockmark is relatively common in the main producing areas of angelica, such as Gansu, Yunnan, and Shaanxi, and it has become more serious in recent years. Angelica pockmark is a very stubborn and difficult to control disease in the planting process of angelica, which occurs on a large scale every year. . As long as the root of Angelica sinensis is harmed, the incidence rate in the field is more than 20%, and the yield is reduced by more than 10%. It is spongy and lignified, which seriously affects the appearance and commerciality of angelica, and obviously affects the quality. The reasons for the occurrence of pitting disease in angelica are quite complicated, and there are both germs and underground pests. However, path...
