Method for planting Gastrodia elata with single tuber weight 150 grams or above

Abstract

The invention provides a method for planting Gastrodia elata with single tuber weight 150 grams or above. A sloping field at an altitude of 1000-1500 meters is selected; planting land at a width of 1.2 meters is prepared, and working channels are reserved on both sides of the planting land; fresh timber with the diameter 6-10 cm is selected, the fresh timber is cut into a fungus-growing material at the length of 12 cm, the fungus-growing material is straightly planted according to the slope, the fungus-growing material is densely arranged in a row with the cross section erecting upward and then densely arranged in a row in the transverse direction, the fungus-growing material is arranged into a whole crossing transversely and vertically, positions for placing Armillaria mellea masses are reserved in the crossing positions, and soil with the depth 10-12 cm covers the fungus-growing material to cultivate the Armillaria mellea after the Armillaria mellea masses are placed; in early springand after thawing, zero-generation seeds with the length equal to or larger than 5 cm of Gastrodia elata are selected, placed on the cross section of the fungus-growing material vertically arranged and covered with fresh branches or corncobs, and soil covering cultivation is conducted; when the air temperature is lower than 12 DEG C, plastic film is used for thermal insulation, water is sprayed for moisture retention and dredging drainage is conducted during drought, and a shed is erected for sun shade when the air temperature is higher than 30 DEG C. By means of the method, the growth speedof Gastrodia elata can be increased by 5-7 times, and single tuber weight can reach 150 grams or above.

Description

technical field [0001] The invention relates to a method for planting Gastrodia elata, in particular to a method for planting Gastrodia elata with a weight of more than 150 grams. Background technique [0002] Gastrodia elata is a medicinal and edible orchid plant. Gastrodia elata needs to establish a symbiotic relationship with Armillaria armillaria in the growth process. Armillaria elata provides nutrients to grow, and Armillaria armillaria is a saprophytic and parasitic fungus. Its nutrients Derived from wood. The vigorous growth of Armillaria can provide more nutrients for Gastrodia elata, and can better promote the high yield of Gastrodia elata. At present, Gastrodia elata is planted according to the traditional method. This traditional method will make the growth of Armillaria elata uneven due to various reasons. , combined with mixed sowing of Gastrodia elata seed size and too high sowing density, resulting in Gastrodia elata harvest weight is too small, because Gast...

The vigorous growth of Armillaria can provide more nutrients for Gastrodia elata, and can better promote the high yield of Gastrodia elata. At present, Gastrodia elata is planted according to the traditional method. This traditional method will make the growth of Armillaria elata uneven due to various reasons. , combined with mixed sowing of Gastrodia elata seed size and too high sowing density, resulting in Gastrodia elata harvest weight is too small, because Gastrodia elata market enters the market based on tuber size and individual weight, for this reason, too small Gastrodia elata directly affects market development and economic benefits
