Embodiment 1

[0024] Embodiment 1: antifreeze treatment method

[0025] Adopt the inventive method to be positioned at 50 mu of Dendrobium candidum of Tongli Town, Wujiang District, Suzhou City, Jiangsu Province to carry out antifreeze treatment, specifically as follows:

[0026] (1), on November 4th, 2013 (Gregorian calendar), ditch fertilization between Dendrobium officinale plants, and water thoroughly, the applied fertilizer is semi-fermented organic fertilizer, which is made of sheep manure and rapeseed cake The mixed organic fertilizer with a composition of 2:1 is obtained by composting and fermenting for 30 days, and a total of 500kg of fertilizer is applied per mu of Dendrobium officinale.

[0027] (2), on the morning of November 19, 2013 (Gregorian calendar), evenly spray methyl jasmonate medicament (100 μmol L-1 methyl jasmonate aqueous solution) once on the leaf surface of Dendrobium officinale, spraying can adopt sprayer or sprayer , spray until the leaves are completely wetted...

Embodiment 2

[0032] Embodiment 2: the influence of methyl jasmonate aqueous solution concentration on antifreeze effect

[0033] On the morning of November 19, 2013, the leaves of different Dendrobium officinale plants in the same area were sprayed with water, 50 μmol L-1 aqueous solution of methyl jasmonate, 100 μmol L-1 aqueous solution of methyl jasmonate, 200 μmol L-1 The aqueous solution of 1 methyl jasmonate and the aqueous solution of 400 μ mol L-1 methyl jasmonate, until completely wet, count the number of yellow leaves before spraying and one week after spraying, and sample and measure the relative conductivity of the leaves simultaneously (measurement method Same as above), see Table 1 for the results.

[0034] Table 1 Changes in the number of yellow leaves and relative conductivity of Dendrobium candidum treated with different concentrations

[0035]

[0036] Note: The smaller the relative conductivity value, the lower the degree of freezing.

[0037] It can be seen from Ta...

Abstract

The invention relates to a winter anti-freezing method for dendrobium officinale. The method comprises the following steps: 1, trenching among dendrobium officinale plants for applying a fertilizer, and irrigating completely, wherein the applied fertilizer is a semi-fermented organic fertilizer, and is applied within half a month before the beginning of winter or the full-day lowest temperature falls to 5-8 DEG C, whichever comes first; 2, when the full-day lowest temperature falls to 3-5 DEG C, uniformly spraying a jasmonic acid methyl ester agent onto the leaves of dendrobium officinale in the morning of a sunny day; 3, when the full-day lowest temperature falls to 0-2 DEG C, covering the surface of dendrobium officinale with a layer of one-side-brush non-woven fabric, wherein the fabric surface of the one-side-brush non-woven fabric faces downwards. The dendrobium officinale cultivated according to the method has the advantages of no leaf falling in winter, no loss of nutrition in plant bodies, no need of manual curing and less diseases in winter; in the next spring, new buds emerge early and the plants grow robustly, thereby realizing low consumption, high quality and high yield in manual cultivation of dendrobium officinale.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a winter antifreeze method for dendrobium officinale. Background technique [0002] Dendrobium candidum is a commonly used precious traditional Chinese medicine with a long history of application. It is listed as the top grade in "Shen Nong's Materia Medica". "Compendium of Materia Medica" records that Dendrobium "strengthens yin and nourishes essence. Long-term use will thicken the stomach. It will absolutely nourish the deficiency, calm the stomach, and grow muscles... lighten the body and prolong life." [0003] The natural growth conditions of Dendrobium officinale are harsh, and the high demand of people leads to over-harvesting. At present, wild Dendrobium officinale resources are very scarce. As early as the 1980s, Dendrobium officinale was listed as a rare and endangered medicinal plant under national key protection. Nowadays, the tissue culture and seedling bree...
