Reason:
Growing environment of Gastrodia elata: Gastrodia elata is born in humid forest with more humus, and also in sunny shrubs and grass slopes. It must grow with Armillaria mellea and Pleurotus ostreatus of Tricholomataceae, so that the seeds can germinate, form round bulbs and grow into healthy gastrodia elata. Osmunda japonica provides nutrition for seed germination, and Armillaria mellea provides nutrition for protococcus to grow into gastrodia elata.
Because the artificial planting technology of Gastrodia elata is very mature now, the planting conditions are relaxed. Gastrodia elata can be planted as long as the following conditions are met.
① There are suitable gastrodia elata planting.
Raw material resources-wood, except pine and fir, other miscellaneous trees including aromatic oil-soaked trees can be used.
② Sandy soil, sandy soil, loose, breathable and drained soil or river sand.
(3) Need to invest in the purchase of excellent gastrodia elata and Armillaria mellea varieties.
Selection of planting location of gastrodia elata;
It should be planted in gentle slopes and valleys rich in organic matter, loose loam, sandy loam or sandy soil with good drainage, especially in raw wasteland. The pH value of the soil is 5 ~ 6. Avoid clay, waterlogging and continuous cropping.
How to select gastrodia elata seeds;
Gastrodia elata can be used as limited reproduction and unlimited reproduction. When selecting hemp seeds, select gastrodia elata which was dug in the same year, and remove commercial hemp. After selecting all hemp seeds, screen them, and remove inferior hemp seeds such as rotten hemp and deformed hemp. Finally, it is determined that gastrodia elata with the same size, strong appearance, big head, good color and no trauma will be used as hemp seed in the following year.
Post-planting management of Gastrodia elata;
After planting, Gastrodia elata does not need fertilization or loosening soil to weed, and it remains wild. The soil moisture content should be kept at about 40%, and the ground temperature should be 15-28 degrees. Spraying Gendaling solution on the leaves during the rhizome swelling period can promote the transportation of photosynthetic products (nutrients) on the leaves to the roots, improve the nutrient conversion rate and soil loosening ability, make the rhizome swell rapidly, and greatly increase the content of effective substances. In summer and high temperature season, use sunshade net or branches to shade and cool down to prevent people and animals from trampling.
Prevention and control of diseases and pests in planting gastrodia elata;
Gastrodia elata diseases mainly include root disorder, and there are two reasons for root disorder: first, miscellaneous bacteria invade the root of Gastrodia elata; Second, there is too much rain during the growth period, which makes the root system of Gastrodia elata disordered. Prevention and control methods: Select the ground-planted gastrodia elata with good drainage. There is no mixed bacteria infection in bacteria, and the gaps between bacteria should be filled. Always pay attention to drainage. Prevention and treatment methods: spraying targeted drugs+800 times solution of new high-fat film to kill. The main pests are grubs and crickets. Prevention and control methods: spraying targeted drugs to kill or lure adults with lights.
