At the same time, it depends on whether it is 0 generation or 1 generation seed. Generally, the price difference between 0 generation seed and 1 generation seed is doubled. 0 generation Gastrodia elata seeds per jin can be planted about 1.5 square meters, while a generation of Gastrodia elata seeds can plant 1 square seed.

Selection and purchase method of Gastrodia elata seeds

1. We must choose fresh Gastrodia elata for planting, that is, do not buy Gastrodia elata seeds that have been stored for too long and try to choose Gastrodia elata seeds that have just been dug up.

4, do not buy seeds of the same size, such seeds are basically selected from the eliminated Gastrodia elata seeds as high-quality Gastrodia elata seeds to buy, except for on-site mining.

5. Do not buy Gastrodia elata seeds in Sha Tian, which is not suitable for long-distance transportation. The reason is that sand will friction with Gastrodia elata seeds during transportation, and damage to Gastrodia elata seeds will affect the seed survival rate!

Cultivation techniques of Gastrodia elata seeds

1. Cultivation time: the cultivation time of Gastrodia elata is generally from late October to April of the following year, sowing is winter planting before soil freezing from late October to early December, sowing is spring planting after soil thawing in March and April, and sowing time in high altitude mountain area can be postponed to May.

2. Cultivation site: the cultivation site of Gastrodia elata can choose any land such as front and back house, wilderness slope land, orchard woodland and so on, especially the sandy loam with strong air permeability and water permeability. The suitable temperature for growth is 10: 30 ℃, the optimum temperature is 20: 25 ℃, the air relative humidity is about 80%, the soil water content is 50% 55%, and the pH value is 5% 6, that is, the slightly acidic ecological environment.

3. Land preparation and border construction: the flat land can be made on the spot according to the width of 80 cm, depth of 10 cm and unlimited length. A trapezoidal horizontal border can be built on the wilderness slope depending on the slope topography. The distance between the border and the border is about 1 meter, and the trees and weeds on the border can be retained as far as possible. It is easy to shade, prevent border ridge collapse or ridge collapse. Orchard woodland is built according to the topography, and drainage ditches are dug around.

4. Temperature management: the suitable temperature for Gastrodia elata production is 1325 degrees, in this temperature range, the higher the better. To prevent freezing in winter, areas below 1000 meters above sea level can be covered with branches and leaves and weeds 10 to 20 centimeters thick after planting, and the mulch can be thickened to 30 centimeters in areas above 1000 meters. Summer and autumn to prevent high temperature and drought, in addition to the use of shade to prevent high temperature, but also the use of water does not reduce the soil temperature. Replenish water after sunset and soil temperature drop.
