Embodiment 1

[0028] 1) Seed collection: Select the wild cold-resistant palm fruit to begin to collect seeds when the seeds fall off, remove the cold-resistant palm fruit with small insect excrement near the outside of the cold-resistant palm fruit and the fruit stalk, pick the intact cold-resistant palm fruit, and set aside ;

[0029] 2) Seed selection: immerse the cold-resistant palm fruit in water for 36 hours after seed collection, remove the cold-resistant palm fruit that has surfaced, select the good cold-resistant palm fruit that has sunk, and dry and thresh it in the shade to obtain cold-resistant palm fruit seed;

[0030] 3) Seed cold-resistant treatment: first use 0.2% potassium permanganate to sterilize the cold-resistant palm seeds for 15 minutes, rinse the cold-resistant palm seeds with distilled water after disinfection, and dry the surface moisture of the cold-resistant palm seeds in the shade Finally, soak the cold-resistant palm seeds in 30mg / L magnesium chloride solution ...

Embodiment 2

[0037] 1) Seed collection: Select the wild cold-resistant palm fruit to begin to collect seeds when the seeds fall off, remove the cold-resistant palm fruit with small insect excrement near the outside of the cold-resistant palm fruit and the fruit stalk, pick the intact cold-resistant palm fruit, and set aside ;

[0038]2) Seed selection: immerse the cold-resistant palm fruit in water for 48 hours after seed collection, remove the cold-resistant palm fruit that has surfaced, select the good cold-resistant palm fruit that has sunk and dry it in the shade and thresh it to obtain cold-resistant palm fruit seed;

[0039] 3) Seed cold-resistant treatment: first use 0.5% potassium permanganate to sterilize the cold-resistant palm seeds for 20 minutes, rinse the cold-resistant palm seeds with distilled water after disinfection, and dry the surface moisture of the cold-resistant palm seeds in the shade Afterwards, place the cold-resistant palm seeds in 40 mg / L magnesium chloride sol...

Abstract

The invention relates to the technical field of seedling cultivation, in particular to a cultivation method of cold-resistant palms, which is characterized by comprising the steps of seed collection, seed selection, seed cold-resistant treatment, pregermination, sowing, seedling management, cold acclimation and cold-resistant palm haploid breeding. The method has the beneficial effects that the seedling emergence rate of palm seeds during planting in the processes of seed collection and seed selection is ensured; the stability of cell membranes of the palm seeds and the activity of antioxidant enzyme in cells are improved by performing cold-resistant treatment on the palm seeds, so that the cold resistance of palm seedlings erupted after the palm seeds are germinated is improved; due to the adoption of the cold acclimation process, the palm seedlings gradually obtain better cold-resistant exercise, the palm seedlings with better cold-resistant ability are screened out, a foundation is provided for the cultivation of cold-resistant palms with trunks and leaves which are thicker and stronger than those of common palms, the ability of resisting external severe environment is enhanced, and the draught resistance ability is also improved while the cold resistance is enhanced.

Description

technical field [0001] The invention relates to the technical field of nursery stock cultivation, in particular to a method for cultivating cold-resistant palms. Background technique [0002] Palm (Trachycarpus fortune) is native to China and is now cultivated all over the world. It is one of the most cold-resistant Palmae plants in the world. Palms in China are mainly distributed in warm, humid and rainy areas south of the Qinling Mountains and the Yangtze River Basin, with the most in Sichuan, Yunnan, Guizhou, Hunan, Hubei, and Shaanxi. They are vertically distributed at an altitude of 300-1,500 meters, and can reach 2,700 meters in the southwest region. Palm likes a warm and humid climate, extremely cold-tolerant, relatively shade-tolerant, and the finished product is extremely drought-tolerant, but it cannot withstand too large a temperature difference between day and night. [0003] Cultivation soil requires good drainage and fertile. The root system of the palm is re...
