Pest control skills of how to plant Gastrodia elata

Gastrodia elata, also known as Aristolochia mandshurica, Tongtuo or Tongcao, is a shrub or small tree of the family Araliaceae. In fact, Gastrodia elata was originally produced in South China and Taiwan, and is generally used to make rice paper, while the center of the stem of Gastrodia elata can be used to make watercolor paper and surgical dressings. Gastrodia elata is also a perennial parasitic herb, generally as high as 60 to 100 centimeters. We all know that different plants have their own unique planting techniques, so let's take you to know the planting techniques of Gastrodia elata.

I. growth environment requirements

Born under humus-rich and moist forests, sunny thickets and grassy slopes. It must be symbiotic with Agaricaceae fungus and Osmunda Osmunda in order to make the seeds germinate, form round bulbs and grow into normal Gastrodia elata tubers. Pleurotus ostreatus provided nutrition for seed germination and Armillaria mellea provided nutrition for protococci to grow into Gastrodia elata tubers.

Second, the choice of planting site

It is appropriate to choose gentle slope land and valley gully land rich in organic matter for planting, and the soil quality is loose loam, well-drained sandy loam or sandy soil, especially wasteland. Soil PH5~6 is suitable. Avoid clay and waterlogged waterlogged land, avoid stubble.

Third, how to select species

It can be used as two kinds of limited reproduction and unlimited reproduction. Gastrodia elata dug up in the same year is selected when selecting hemp species, commercial hemp is removed, all flax species are selected and re-screened, rotten hemp, deformed hemp and other inferior hemp species are selected, and finally determined as the same size, robust, neat appearance, large size, good color, non-invasive Gastrodia elata as the next year of use of Gastrodia elata.

IV. Post-planting management

After planting, there is no need to apply fertilizer, no need to loosen the soil and weed, and keep it wild. The soil water content should be kept at about 40% and the ground temperature should be kept at 15-28 degrees. Spraying Gandaling solution on the leaf surface during the rhizome expansion period can promote the transport of foliar photosynthetic products (nutrients) to the root system, improve the nutrient conversion rate and the ability of loosening soil, make the rhizome expand rapidly, and the content of effective substances is greatly increased. Sunshade net or branches should be used to shade and cool down in summer high temperature season to prevent people and animals from trampling.

V. Pest control

The diseases of Gastrodia elata are mainly caused by disorderly root disease, which is caused by two reasons: one is that miscellaneous bacteria invade the roots of Gastrodia elata, and the other is that too much Rain Water in the growing period makes Gastrodia elata root chaos. Prevention and cure method: choose the ground planting Gastrodia elata with good drainage. The fungus material has no miscellaneous bacteria infection, and the gap between the fungus materials should be filled up. Always pay attention to drainage. Spray targeted drugs + 800-fold solution of new high-fat membrane to kill. The main insect pests are grubs and mole crickets. Spray targeted drugs to kill or trap adults with light.

Well, the above is the detailed explanation of the planting technology of Gastrodia elata. There may be many friends who know little about Gastrodia elata and have not even seen it. In fact, friends who have lived in the countryside or have been to the suburbs should all see this plant, but they just don't know that it is Gastrodia elata. Each plant has its own corresponding planting technology, which requires specific temperature, humidity, light and so on. If you do not understand the planting technology of Gastrodia elata, it may take some time to explore its planting technology.
