Problems solved by technology

Although this method has achieved the cultivation of Gastrodia elata indoors, when cultivating indoors, insects or natural wind cannot be used to realize the pollination of Gastrodia elata; in addition, because Gastrodia elata blooms more, when artificially pollinating many flowers, It is easy to confuse which flowers have already been pollinated, resulting in repeated pollination, and it is easy to damage the structure in the process of repeated pollination, which will affect the successful pollination of Gastrodia elata and ultimately affect the yield

Embodiment 1

[0020] A kind of high-efficiency sexual reproduction method of Gastrodia elata, comprising the steps:

[0021] (1) First, dig a groove with an isosceles trapezoid on the slope with an inclination angle of 15°. The bottom of the groove is 1 meter long, the depth is 0.8 meters, and the upper opening width is 2 meters. Gastrodia elata seeds are planted on both sides of the groove and at the bottom of the groove, and drainage ditches are opened around the groove, and the covering soil at the bottom of the groove is gathered up to the middle;

[0022] (2) Pollen collection: After Gastrodia elata blooms, use tweezers to pluck the stamens from the flowers, put them on a cotton cloth dampened with water, and then shake the cotton cloth to make the stamens fully contact and mix;

[0023] (3) From 9 to 14 every day, when the stigma of the pistil begins to secrete mucus, gently press the stamen on the stigma of the pistil with tweezers, so that the stamen and the stigma of the pistil are...

Abstract

The invention relates to the technical field of crop cultivation, specifically to a highly-efficient sexual propagation method for gastrodia tuber. The method mainly comprises the following steps: planting distribution during planting of the gastrodia tuber, pollen collection after flowering, pollination by adopting a manner of xenogamy, and sealed protection of pollinated flowers by using cobwebs. According to a scheme of the invention, through improvement of a pollination method, the success rate of pollination is effectively improved; the propagation effect of the gastrodia tuber in the later period is better; and the yield of the gastrodia tuber is improved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for efficient sexual reproduction of Gastrodia elata. Background technique [0002] Gastrodia elata is an orchid with mycorrhizae, without roots and green leaves, and cannot produce nutrients for its own growth. After germination, the seeds of Gastrodia elata mainly rely on the decomposition of Armillaria which invades its body to grow. The mature tuber of Gastrodia elata is a precious Chinese medicinal material, known as "the second ginseng", and it is a good medicine for curing diseases and health preservation in my country in all dynasties. Gastrodia elata has the functions of dispelling rheumatism, anticonvulsant, dizziness and lowering blood pressure in the treatment of diseases, especially in analgesia and sedation. aspect. Due to the limited resources of Gastrodia elata, my country has actively carried out artificial cultivation in the cultivation of Ga...
