Disease prevention and control of ginseng fruit planting is very important, what are the disease pre

The damaged part is light yellow-brown, gradually turns into dark yellow-brown, forms a concave long spot, penetrates deep into the stem and rots, and the diseased part is black-brown and ring-like shrinkage after expansion, cutting off the infusion tissue, so that the ginseng seedlings lodging and dying. It can be seen that the diseased part is wound with white hyphae and sticks to the soil particles. Ginseng is mainly self-toxic and excreted, resulting in nutrient inability to absorb and black rot; Then there are physiological diseases caused by soil bacteria, fungi and viruses and nutrient deficiencies, spot disease, yellowing, anthracnose, etc.

Methods pay attention to the root cause of the problem, repair the soil.

The disease mainly affects the leaves, but the base and roots can also be damaged. 7 Occurs during the rainy season in August when the humidity is high. Plants that are more than 4 years old are particularly affected.

The lesions on the leaves are water-stained and dark green. The roots are infected, yellow-brown soft rot, the root bark is easy to peel off, control methods: 1 2 months before sowing, fumigation of soil with 80 120 ml of chloropicrin per square meter.

When making a bed, apply 0 0 01 0 015 kg of carbendazim wettable powder per square meter, and mix people in a soil layer 3-5 cm deep for soil disinfection, <>

The environment is very important, people like to be shaded and damp, and the sun cannot be directly exposed to the disease, which mainly affects the leaves, and the base and roots can also be damaged. 7 Occurs during the rainy season in August when the humidity is high. Plants that are more than 4 years old are particularly affected.

The lesions on the leaves are water-stained and dark green. The roots are infected, yellow-brown and soft rot, and the root bark is easy to peel off and <>

Ginseng originally referred to wild ginseng, **expensive, it has been difficult to see wild ginseng in recent decades, the world is basically planted ginseng, ** is also very cheap, so there is no need to be too ......The main insect pests that harm ginseng are: needleworm, mole cricket, grub, ground tiger and grass borer. They are widely distributed, miscellaneous, and harmful, and the victim ginseng is pore and notched and susceptible to the occurrence of disease, which greatly reduces the yield and quality of ginseng in the early stage of the disease

1:120 Bordeaux liquid, 40 ethylphosphine aluminum 300 times liquid or 58 methalenescofenct 1000 times liquid or watering the middle and lower parts of the plant and soil surface, it is best to spray after heavy rain, 7 10 days 1 time, 2 3 times in a row.

Strengthen ventilation, cut off diseased branches, spray some pesticides, improve the nutrients of plants, choose good seeds, and bask in the sun.

First of all, when planting, you must choose a land with relatively fertile and wide soil. In the process of fertilization, you must choose farmhouse fertilizer, do not use fertilizer bought outside. It is also necessary to water more often, and it is also necessary to prevent the occurrence of pests and diseases, and if there are small bugs, then be sure to spray insecticides.

Fertile soil should be chosen, and timely watering and fertilization should be carried out, and the management of water and fertilizer should also be strengthened, and sufficient light should also be ensured, and the soil should be loosened in time, and pesticides should also be sprayed regularly, and pest control work should be done, and the right medicine should also be prescribed.

It's not difficult at all. The requirements for the environment are also not harsh. When choosing soil, you must choose a deep soil layer, well-drained soil, preferably with a certain amount of fertilizer, the temperature should be controlled at 13 25 degrees Celsius, pay attention to cleaning up stagnant water, fertilizing, spraying pesticides, and cleaning up insect pests.

It is more difficult to plant, and the requirements for the environment are particularly harsh, and it is necessary to ensure that there is no special smell in the environment, and the temperature in the environment needs to be kept at 18.

It is not particularly difficult to grow, the requirements for the environment are not particularly harsh, life needs a lot of light, and some moist soil is also needed.

The more common diseases of ginseng fruit are mainly leaf mold, cotton blight, etc., you can choose varieties with disease resistance when planting, and the seeds contain disease resistance genes, which are slightly disinfected before sowing, which is conducive to the prevention and control of fruit lesions. After that, if it is infected, the diseased seedlings should be removed in time, and the weak branches and buds should be removed at ordinary maintenance, and pesticides should be sprayed appropriately.

Disease type: Leaf mold.

When it comes to leaf mold, it usually harms the leaves of the ginseng fruit. This disease first occurs on the leaves, and the back of the leaves will produce white mold, and slowly the leaves will become yellow, and then the phenomenon of leaf curling will appear. This phenomenon will spread upwards from the bottom leaves, resulting in a large area of leaf drop, which greatly affects the growth of the fruit.

Sheep blight. Cotton blight is a condition that severely affects fruit development, usually with faint brown spots at the tips of the fruit. Slowly white moldy substances will grow on the surface, this fungus will gradually corrode to the inside of the fruit, after the wet rainy season, the diseased fruit will fall off the neck, resulting in a large area of fruit tree yield reduction, extremely harmful.

Governance Approach. In the prevention and control of diseases, you can plant tree species with disease resistance, the seeds contain disease resistance genes, and a little disinfection can be carried out before sowing. Planting this tree species is conducive to the prevention and control of fruit lesions, which can effectively reduce the infection of fruits with cotton blight, and is a relatively good treatment method.

Another method is to strengthen the management of planting soil, select seedlings without pests and diseases for cultivation and propagation, and clean up the potting soil of the cultivated seedlings to avoid the growth of weeds and cause pest and disease infection. In addition, it is necessary to pay attention to the condition of the seedlings from time to time, and remove the seedlings that have diseased. When tidying up the branches, keep the healthy branches and leaves, remove the weakly growing friendly branches and buds, and spray pesticides appropriately to ensure the control of bacteria, so that the ginseng fruit can grow normally.

Type of disease. Leaf mold.

When it comes to leaf code stupid mold, it is generally harmful to the leaves of ginseng fruit. The disease first occurs on the leaves, where white mold is produced on the back of the leaves, and then the leaves slowly turn yellow, and then the leaves curl. This phenomenon will spread upwards from the bottom leaves, causing the leaves to fall out in large areas, which will greatly affect the growth of the fruit.

Sheep blight. Cotton wilt is a disease that seriously affects fruit development. Typically, light brown spots will grow on the top of the fruit.

Slowly, white mold grows on the surface, and this fungus will gradually corrode the inside of the fruit. After the wet rainy season, the diseased fruit will fall off the neck, resulting in a large area of fruit tree yield reduction, which is extremely harmful.

Governance Approach. In the case of disease control, disease-resistant tree species can be planted, and the seeds contain disease resistance genes, which can be slightly sterilized before sowing. The planting of this tree species is conducive to the prevention and control of fruit diseases, which can effectively reduce the infection of cotton wilt disease on fruits, and is a better control method.

Another method is to strengthen the management of planting soil, select seedlings free of diseases and pests for breeding, and clean up the potting soil of the cultivated seedlings to avoid weed growth and pest and disease infection. In addition, it is necessary to always pay attention to the state of the seedlings and remove the diseased seedlings. When tidying up the branches, maintaining healthy branches and leaves, removing weak branches and buds, spraying pesticides appropriately, and controlling bacteria are the normal growth of ginseng fruits.

Among them, Mr. Peng Muer fermented in traditional Chinese medicine, seaweed, and maifan stone by decomposing biological bacteria to provide nutrients for the germination of ginseng next year, and nourished the regenerated plants to enhance their disease resistance and stress resistance. By increasing the concentration of the drug after the disease, shortening the preparation interval, three-dimensional, in the form of a compound with the drug ** of the Chinese herbal medicine preparation is safe, high concentration can be used continuously, once the disease is controlled and has a cumulative effect, it can not only sterilize the treatment, but also provide a variety of nutrients for the crop, it can make the crop stronger, enhance its disease resistance and stress resistance.

With the gradual improvement of people's living standards, the demand for health care products is increasing day by day. The development of new varieties of health foods and cosmetics is also active, and ginseng is needed for many new products. On the other hand, many Western countries have begun to develop and apply Chinese herbal medicines.

Many factors indicate that the demand for ginseng will gradually increase in the future. However, in China's main ginseng-producing areas, especially in Jilin Province, ginseng cultivation is based on the traditional method of clearing forest land. At present, the state has begun to attach importance to the protection of the natural environment, prohibiting the reclamation of forest land, and implementing the policy of returning farmland to forests.

The main pests of ginseng are underground pests such as golden needles, ground tigers, grubs, moles, and crickets. These pests are resistant to pesticides and are usually underground, making them difficult to control after a pest has occurred. Before planting or transplanting, the insects should be carefully investigated and, if found, controlled in advance.

1000 times solution of insecticides such as acaricide or phosphine, mixed with rake bed soil after 6-8 times per square meter.

When choosing a woodland, pay attention to the vegetation. Choose fields where trees such as oaks, lindens, and broadleaf weeds grow, and avoid plots where birch, poplar, willow, and leaf grasses dominate. When choosing farmland, you should first plant beans, corn, etc., and do not use beets, sunflowers, cabbage, radishes, etc.

Once planted, ginseng needs to be kept in a cool place, reflect sunlight, and grow at natural temperatures. It is important to note that people prefer cold places. For the first watering, water along the sides of the jar to avoid the formation of spores when watering.

It is best not to pour water from the tap, because most of the tap water is said to contain bleaching powder, and the amount of watering should be appropriate to avoid root rot and dryness.

The key point of ginseng disease prevention and control is to adopt scientific methods for management, water in time after planting, clean up the surrounding weeds in time, ensure that the planting environment is clean and tidy, and spray nutrient solution on schedule, regularly repel insects and disasters; Because ginseng has a relatively high nutritional value and is a crop with great economic value, many people grow ginseng; When planting ginseng, it is necessary to cultivate ginseng seedlings first, cultivate the ginseng seedlings to a certain extent, and then plant Qinzhou to a fixed site, water it on time, keep the sun sufficient, ensure that the environment is moist, and let the ginseng grow rapidly.

To do a good job in prevention and control, to ensure soil fertility, to use pesticides, herbicides, fungicides, because in this way can improve the utilization rate of land; It is necessary to choose fertile soil, to choose high-quality and stuffy seeds, to do a good job in seedling raising, and to water and fertilize in a timely manner. Temperature and humidity should be ensured. Branching source.

Ginseng and this is a very nutritious traditional Chinese medicine called Xun Cai, and advanced science and technology need to be used to prevent pests and diseases when growing ginseng. The key is to cultivate a good diet.
