Ginseng and American ginseng anti-double weight cultivation techniques

The main cause of continuous cropping obstacles is root-knot nematode damage, and soil-borne diseases such as root rot and blight. However, the author has discovered that there is still another problem through field surveys and research in recent years. One of the important reasons for the obstacles. The so-called self-toxicity of plants means that various plants will secrete some harmful substances that inhibit their own growth during their growth. Most of these harmful substances are excreted into the soil through the root system and are extremely resistant to decomposition. With the increase in the number of continuous cropping, the accumulation of these harmful substances in the soil is also increasing, which significantly inhibits the growth of the plant itself. It is manifested as weak growth, decreased resistance, and reduced yield. This phenomenon is particularly prominent in the cultivation of vegetables in protected areas. For example, for a plot of tomato growing for 8 consecutive years, the unlimited-growth variety can only harvest 5–6 ear fruit if the crop is rich in fertilizer and water. The plants are dying and dying; the yield of strawberries on the plots of 4-5 years of continuous cropping is only 70-80% of that of the newly planted plots; the same crops are also found in hot and sweet peppers, eggplants, cucumbers, and watermelons. Happening. The yield loss caused by the plant's self-toxicity is no less than that of the pest.

Another major problem of continuous cropping obstacles is root-knot nematodes. At present, due to the lack of effective pesticides to control root-knot nematode disease of melon, about 20% of vegetable greenhouses are destroyed due to illness in some areas, and the prevalence rate is about 30%. 80% or so. The use of phorate-containing phosphorus, carbofuran, aldicarb, and other giant poisonous pesticides is not satisfactory, and causes serious pollution, and does not meet the requirements for the production of green, pollution-free agricultural products.

Soil-borne diseases in protected areas are mainly caused by continuous cultivation of the same or similar crops such as tomatoes, green peppers, cucumbers, melons, strawberries, ginger, and Chinese herbal medicines by farmers on the same land for many years, resulting in the accumulation of large amounts of pathogenic bacteria in the soil. Fertilizers, pesticides, etc., cause serious degradation of the soil in the protected areas, resulting in soil-borne (double crop) diseases such as: root rot, blight, blight, bacterial wilt, black stem, stem rot, anthrax Diseases such as clubroot, swollen diseases, and so on, resulting in weak growing crops, reduced yield, and some even out of production. Most of the crops showed that they did not show any symptoms at the early stage of growth, but they began to die when they were flowering, and they basically died out in the full fruit period. Soil-borne diseases such as root rot and blight have occurred throughout the country, especially in areas where protected areas are planted. The high incidence and large area has become a bottleneck that severely restricts farmers' production and income.

In order to solve the difficult problems of farmers who have been trapped in protected areas for many years, local scientific research departments and farmers' friends have done a lot of scientific experiments. At present, the main solutions used are: pharmaceutical disinfection method, high temperature disinfection method, frozen disinfection method, changing soil and so on. In the process of using these methods, not only the workload is large, the labor intensity is high, but also the cost is high, and the solution to the problem is not complete, and often the task is less effective. There is currently no way or agent to solve this problem. After years of hard work, we have taken comprehensive use of technologies such as biology, chemistry, and physics to effectively solve these problems. Among them, the successful soil purifiers - Ye Bao-Green 4, etc., can degrade these autotoxic substances and passivate the heavy metals in the soil within a few days, and can also degrade residual pesticides in the soil and cause root rot. Diseases caused by soil-borne diseases such as wilt disease and wilt disease, etc. Effectively solve the problems of tomato, green pepper, cucumber, melon, grass ginseng

The main reason why ginseng and American ginseng could not be planted repeatedly was the large amount of pathogenic bacteria in the soil and the excessive accumulation of self-toxic substances in the plants. This technology combines the traditional production methods of ginseng and American ginseng with modern agricultural cultivation techniques, can effectively solve the problem of continuous cropping obstacles of ginseng and American ginseng, promote the healthy development of ginseng business, and is the only way for the cultivation of ginseng and American ginseng without pollution.

The characteristics of this technology are:

1. The old ginseng land can be reused to save the construction cost;

2, after planting (planting) does not require frequent transplanting, reducing the amount of work, but also conducive to continuous growth of ginseng;

3. It is convenient to regularly supplement effective nutrients and remove pathogenic toxins, which is conducive to the healthy growth of ginseng and American ginseng and the cultivation of large individuals.

4. The bar body is upright and the commodity value is high;

5, to ease the conflicts between forests and forests and to facilitate the implementation of natural forest protection projects.
