Method for introducing and domesticating paphiopedilum armeniacum in south China
The technical field is as follows:
the invention belongs to the field of plant protection biology and cultivation, and particularly relates to a method for introducing and domesticating paphiopedilum armeniacum in south China.
Background art:
paphiopedilum armeniacum (S.C.Chen & F.Y.Liu), also known as "jindou", is a special species in China and is only distributed in the gaps of the rock walls of trees or shrubs growing in mountainous areas where limestone or shrubs grow or in areas where rocky rocks are present in the west of Yunnan province of China, or in areas where drainage is good, and the altitude is 1400 and 2250 meters. Due to extremely high ornamental value, rampant illegal mining and environmental deterioration and damage to the habitat of the wild plants, the number of the wild plants is reduced sharply, the wild plants are listed in appendix I by International trade convention for endangered wild animal and plant species (CITES) and are prohibited from trading, the wild plants are listed as endangered species (EN) to be urgently protected in red name records of the world natural protection alliance (IUCN), and the wild plants listed as extremely small populations in China by the forestry bureau need to be emphatically protected. The ex-situ protection is one of the main methods for protecting the biological diversity of paphiopedilum armeniacum, but when paphiopedilum armeniacum is planted in south China, the growth potential is poor, the survival rate is low, leaves become small, and the paphiopedilum armeniacum is difficult to bloom.
The invention content is as follows:
the invention aims to provide a method for introducing and domesticating paphiopedilum armeniacum in south China, which can realize the biological diversity protection of paphiopedilum armeniacum.
The invention discloses a method for introducing and domesticating paphiopedilum armeniacum in south China, which is characterized by comprising the following steps of:
A. transportation and packaging of materials: collecting paphiopedilum armeniacum plants, collecting and digging several paphiopedilum armeniacum plants by covering roots with moist moss to prevent water loss without cutting stems of the plants connected together when digging the paphiopedilum armeniacum plants, putting the collected paphiopedilum armeniacum plants into a ventilated hard paper box to prevent extrusion, and transporting the paphiopedilum armeniacum plants to an ex-situ conservation greenhouse in south China for cultivation;
B. and (3) cultivation environment: maintaining proper illumination of paphiopedilum armeniacum in an ex-situ conservation greenhouse, controlling the temperature to be 15-35 ℃, and maintaining good ventilation condition in the cultivation process;
C. cultivation management mode: cleaning introduced paphiopedilum armeniacum before planting, washing soil and worm eggs on roots and leaves, cutting rotten roots and leaves, soaking in 800 times of carbendazim diluted solution for 20-40 minutes, taking out, washing with water, drying in the air, planting in a cultivation pot containing a cultivation medium, covering a layer of Chilean imported aquatic weeds on the cultivation medium after planting, soaking the aquatic weeds for 24-72 hours, and wringing out the aquatic weeds by hand for reuse;
spraying 600-800 times carbendazim diluted solution immediately after the introduced and cultivated paphiopedilum armeniacum is planted in a cultivation pot, pouring the cultivation medium through the 600-800 times carbendazim diluted solution, watering once in 2-4 days in a growing season, watering when the cultivation medium is basically dry, spraying water to the ground and the air to improve the air humidity in the cultivation process in dry seasons in summer and autumn, and keeping the relative air humidity of the nursery room at 60-85%; excessive air humidity is prevented to prevent the occurrence of plant diseases and insect pests in high temperature seasons in summer and in winter. When the plants are dried in summer and autumn, water is sprayed on the ground and the air around the plants to increase the air humidity. In winter, the watering is reduced when the temperature is below 15 ℃, and the substrate is kept wet.
The aquatic weed in the invention refers to Chile imported moss for cultivating orchids such as butterfly orchid, and is generally called aquatic weed in the cultivation field.
Recovering 1 month of paphiopedilum armeniacum plantAfter re-growth, the nitrogen, phosphorus and potassium nutrition ratio is 20 after spraying once every half month: 20: more flowers than 20RThe 800-fold diluted solution of the compound fertilizer is applied and sprayed with the nitrogen, phosphorus and potassium nutrition ratio of 10 once per week in 11-12 months before flowering: 30: more flowers than 20RThe solution is diluted by 800 times and 1000 times of the compound fertilizer once and is sprayed to the leaves until water drops. Stopping applying the foliar fertilizer when the temperature is lower than 15 ℃ for 1-2 months, culturing in a pot for 3 months, and the root system recovers growth and the fertilizer effect is half a year of Oridou green second generation 601[10 (nitrogen) -11 (phosphorus) -18 (potassium) +2MgO (magnesium oxide) + TE (iron)]5-10 granules of long-acting slow-release Aolan fertilizer per plant, once per half year;
in the cultivation process, 35% soil-dwelling bacteria wettable powder 1500-fold and 2000-fold diluent, 45% prochloraz 1000-fold and 1200-fold diluent, or 75% carbendazim 600-fold and 800-fold diluent are sprayed once every 2 weeks for alternate use; spraying 40% omethoate emulsion 600-800 times diluent or 40% killing 800-1000 times diluent for one time in another week alternately; can prevent the occurrence of plant diseases and insect pests;
the culture medium is peat soil (imported from Israel), ceramsite with the diameter of 0.5-0.6 cm and pine bark with the volume ratio of 3-4: 2-3: 1, and mixing uniformly.

Paphiopedilum armeniacum is usually provided with a plurality of or a plurality of stems in the underground, and the stem nodes can grow and bud to form new plants. When in ex-situ protection, several plants which are connected together by overground walking stems are adopted to plant together, and the survival rate is high. Therefore, when digging plants in the process of protecting the land, the stem of the connected plants is not cut off. Several plants are harvested together, and these plants often have flowering plants, plants that will bloom, and young plants that have just grown. But the number of plants collected in a community is generally not more than 3, and the collected areas, the communities and the habitat of the plants are respectively marked and recorded.
For the cultivation environment, a fan water curtain greenhouse is adopted in the in-place conservation greenhouse and is provided with an inner sunshade net and an outer sunshade net, wherein the outer sunshade net is a black sunshade net with 75% of sunshade rate, and the inner sunshade net is a silver gray sunshade net with 60% of sunshade rate. In winter, when the sunlight is weak or in cloudy days in other seasons, two layers of sunshade nets are opened; in summer and autumn, when sunlight is strong, two layers of sunshade nets are utilized for shading, and an outer sunshade net is generally adopted for shading. The temperature is kept above 15 ℃ by using a fuel oil heater in winter, and is kept below 35 ℃ by using a water curtain for cooling and enhancing ventilation in summer. In the cultivation process, a circulating fan is used for keeping the good ventilation condition of the greenhouse.
The cultivation pot is cultivated by a plastic sieve of 25 cm multiplied by 25 cm, a layer of black net is padded at the bottom of the plastic sieve, cultivation medium is filled inside the plastic sieve, and 20-30 plants are planted in the pot.
According to the method, the unique culture medium and a proper culture management mode are adopted to protect the paphiopedilum armeniacum ex situ, the protection of the paphiopedilum armeniacum ex situ is successfully realized, the survival rate is more than 80% and the flowering rate is more than 50% after the paphiopedilum armeniacum ex situ is introduced and cultured for 2 years, and an effective method is provided for protecting the paphiopedilum armeniacum ex situ.
