Embodiment 1

[0030] A method for cultivating cuttage seedlings of Supertree under the condition of imitating ecology, comprising the mother plant of Supertree seedlings, and further comprising the following steps:

[0031] (1) To establish an ecologically imitative ear picking nursery, select plots with sufficient light, more pebbles in the ground, and under woodlands with high humidity, and use the biennial super seedlings of Yunnan Provenance Supertree as the mother plant for planting;

[0032] (2) Cultivate the mother plant for ear picking. After the mother plant is planted, it is routinely sprayed with water to protect the pipe. Every 15 days, it is sprayed with a mass concentration of 2‰~5‰potassium dihydrogen phosphate as a foliar fertilizer. After returning to normal growth, it is 30~ Cut off the trunk at 50cm, and apply water and fertilizer with a volume concentration of 5‰ high-nitrogen compound fertilizer (30N-10P-10K) every 15 days, or a volume concentration of 5g / L decomposed ch...

Embodiment 2

[0040] A method for cultivating cuttage seedlings of Supertree under the condition of imitating ecology, comprising the mother plant of Supertree seedlings, establishing an ecologically imitative ear garden and setting up an ecologically imitative cutting seedling shed, and also includes the following steps:

[0041] (1) Cultivate ear-picking mother plants. After the mother plants are planted and resume growth, truncate the top 25cm from the base, and apply water and fertilizer with a volume concentration of 5‰ high-nitrogen compound fertilizer (30N-10P-10K) for 15 days / time to promote germination;

[0042] (2) Selection and treatment of cuttings. Select semi-lignified budding strips with a diameter of 4-4.5mm or more as cuttings, cut to 10cm-12cm long, two internodes, with a leaf on the top of the cuttings, leave 1 / 2 for cuttings The lower incision is a 45-degree angle section, and the incision is smooth;

[0043] Soak the pruned cuttings in 1‰ thiophanate-methyl solution for...

Embodiment 4

[0057] A method for cultivating cuttage seedlings of Supertree under the condition of imitating ecology, comprising the mother plant of Supertree seedlings, establishing an ecologically imitative ear garden and setting up an ecologically imitative cutting seedling shed, and also includes the following steps:

[0058] (1) Cultivate the ear-picking mother plant. After the mother plant is planted and resumes growth, truncate the top 30cm from the base, and apply a volume concentration of 5‰30N-10P-10K high-nitrogen compound fertilizer and water fertilizer every 15 days;

[0059] (2) Selection and treatment of cuttings, select semi-lignified, 3.5-4.5mm budding strips as cuttings, cut to 10cm-12cm long, two internodes, with a leaf on the top of the cuttings, leave 1 / 2, and cut under the cuttings It is a 45-degree angle cut surface, and the cut is smooth;

[0060] Soak the pruned cuttings with a volume concentration of 1‰ thiophanate-methyl solution for 10-20 minutes, take them out ...

Abstract

The invention discloses a method for cultivating parashorea chinensis cutting seedlings under a bionic condition, parashorea chinensis seedling stock plants are involved in the method, and the methodfurther comprises the following steps of establishing a bionic cutting orchard, cultivating scion stock plants, selecting and treating cutting slips, establishing a bionic cutting seedling raising shed, preparing a substrate and carrying out cutting and management. According to the method, a cutting vegetative propagation technology is adopted, influences of the fruit setting age and the fruit setting year of trees can be avoided, stock plants grow fast, the number of effective sprouts is large, bud seedling juveniles are obvious, the vitality is high, the rooting rate reaches 92% or above, the survival rate reaches 90% or above, and the method is an effective way for rapid production of parashorea chinensis seedlings; and the whole technology is reliable, easy to operate, good in seedlingraising effect, large in achievement transformation potential and wide in application and popularization prospect, and has good economic benefits, social benefits and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of asexual rapid propagation of plants, in particular to a method for cultivating cuttage seedlings of Supertree under ecologically imitative conditions. Background technique [0002] Supertree (Parashore chinensis Wang Hsie ), also known as Wangtian tree, is an evergreen tree of Dipterocarpaceae, a genus of Liuan, a national first-class endangered plant, and is the most representative tree species in the Asian tropical rainforest. The trunk is as high as 80 meters, and the diameter at breast height is 60cm to 150cm. It is called "giant in the forest". It dominates the world's timber market due to its excellent material and high volume ratio per plant. According to data, a supertree about 60 meters high can have a trunk wood of more than 10 cubic meters. The average annual growth of a single plant is 0.085 cubic meters, which is 2-3 times that of other tree species in the same forest. Supertree has a har...
