What are the common pests and diseases of Guan Ao? Common pests and diseases of Guanzhong surgery and its prevention and treatment technology
What common pests and diseases will be found in the process of planting Chinese medicine plants? How to prevent it? The following is a scientific research practice of Jinzhou Academy of Agricultural Sciences after several years of scientific research practice, summed up a set of comprehensive control techniques for pest control of Guanzhong, for the development of producers and related personnel in Guanzhong.
1 Site selection and soil conditioning
Soil is an important condition for Guanyu to survive. Only healthy soil can produce high quality Guanzhong. Artificial cultivation of Atractylodes lancea L. should choose sandy loam with good drainage performance, loose soil and rich humus, and it is appropriate to plant plots of compositae in the past 5 years. Before planting Atractylodes lancea L., apply composted organic fertilizer 2 000~ 3 000 kg/mu, compound fertilizer with NPK content of 15:15:15 25 ~ 30 kg/mu, ammonium ammonium nitrate 20 ~ 25 kg/mu, Bio-organic fertilizer 30 ~ 40 kg / acre. In the autumn of last year, the machine was deeply ploughed and the depth was 30~40 cm, which made the soil soft and breathable.
2 Fitness cultivation
Fitness cultivation has only been promoted in recent years, also known as plant immunity. In the past, people paid too much attention to the chemical control of plant diseases and insect pests, which led to the increasing use of Pesticides, the increasing cost of prevention and control, the increasingly poor control effect, and the increasing harm to people and the environment. Through the use of plant-free vaccines, such as Altailing, amino oligosaccharides, etc., to improve the immunity of Guan Aozhi itself, thereby improving the self-resistance of Guan Ao, and easily not feeling pests and diseases, even if it is harmed by pests and diseases, the damage is lighter. Biological pesticides or the application of a small amount of chemical pesticides can play a very good preventive and therapeutic effect. Seeds and seedlings are strictly disinfected, and seeds and seedlings with no disease are selected. Seeds are soaked and sterilized with 70% mancozeb WP 600 times before sowing. 70% mancozeb wettability can be used before transplanting. 600 times liquid powder, 50% carbendazim wettable powder 800 times liquid root. Through scientific production management, timely cultivating and weeding, reasonable irrigation and drainage, and scientific topdressing, in July and August, the flower buds will be removed in time for the non-reserved land, so as to facilitate the healthy growth of plants and improve the ability to resist pests and diseases.
3 Pharmacy prevention and control of major pests and diseases
3.1 Atractylodes root rot
Artificial cultivation of Atractylodes lancea L., the most harmful disease is root rot, the prevention and control of A. sinensis root rot mainly focuses on the following three aspects; First, the use of soil bactericidal to prevent root rot of Atractylodes lancea, more than 50% combined with watering during planting The fungicidal WP 300 times solution is used to prevent root rot. The second is to timely apply the drug to treat the root rot of Atractylodes lancea L., in the early stage of the disease, use Root Ronin WP 1500 times solution and lycopene 400 times solution to fill the roots for 2 ~ 3 times, the application interval is 7 ~ 10 d, which can be very Good treatment of root rot of Atractylodes lancea. The third is reasonable water management to reduce the root rot of Atractylodes lancea. In the spring, when planting Atractylodes lancea, the temperature of the soil will be affected, which will easily cause the root rot of Guanzhong. Therefore, it is very important to control the amount of watering. The correct method of watering is to adhere to the principle of less pouring and pouring in spring watering. When the ground temperature is stable above 15 °C, the amount of water can be increased. After the rain, there is water in the field. It is necessary to drain the water in time to remove the water. The cultivating can increase the permeability of the soil, and it can also prevent the root rot of Guanzhong.
3.2 Atractylodes erythematosus
Atractylodes sinensis black spot usually occurs from June to October. From mid-June, 65% Amisida suspension can be used, 1% solution, 10% high water dispersible granules, 1 200 times solution, 70% mancozeb. The wettable powder was sprayed with 600 times of alternating spray, and applied once every 7 days.
3.3 Atractylodes Locust
There is less rainfall in Jinzhou area, and the continuous drought makes the aphid of Guanguan aggravation more serious. The prevention and control is not only affecting the picking of wild vegetables, but also affecting the normal growth of Guanzhong. In the spring, the seedlings of Atractylodes lancea were unearthed. After the first stems and leaves of A. sinensis were harvested, the biological pesticide was applied to prevent the Aphis sinensis from being unearthed. The general choice was to spray azadirachtin emulsifiable concentrate at a dosage of 50g/mu, which can effectively avoid Guanzhong aphids, once encountered a large number of mites, the preventive effect of azadirachtin is not ideal, can help the application of low-toxic and low-residue chemical pesticides, such as ketones, acetamiprid, etc., can be a good control of Atractylodes sinensis.
The above is the entire content of Guan Chong surgery pest control technology, if you have also planted Guan Ao, you can come to Hui Nong network reference learning!
