Embodiment 1

[0025] In October 2012, a flat, open area with a soil pH value of 5.5, a soil layer thickness of 60 cm, and a loose and convenient irrigation and drainage area was selected as a nursery to remove weeds, stones, and debris, and level the broken soil ,spare. Cultivate for 3 months, seedling height 15 cm, average ground diameter 3.5 mm, grow robustly, and truncate the masson pine tissue culture seedlings without pests and diseases, and select masson pine with 4 or more sprouts and 5-6 cm long buds after truncation The tissue-cultured seedlings were used as the ear-picking mother plant. On November 20, 2013, the ear-picking mother plant was planted in the seedbed at a density of 50 cm × 50 cm.

[0026] After the seedlings are planted, spray the leaves with a mass concentration of 1‰5N-30P-7K high-phosphorus compound fertilizer aqueous solution every 10 days, and trim the seedling height to 10-12 cm on April 16, 2014; Mass concentration 1‰24N-6P-12K high-nitrogen compound fertiliz...

Embodiment 2

[0029] In October 2012, we chose a relatively flat and open area with a soil pH value of 6.4, a soil layer thickness of more than 60 cm, and a loose and convenient irrigation and drainage area as a nursery. Weeds, stones, and debris were removed, and the broken ground Soil, spare. Cultivate for 4 months, seedling height 20 cm, average ground diameter 4.1 mm, vigorous growth, no pests and diseases Pine tissue culture seedlings are truncated, and after truncation, more than 4 sprouts are selected, and 5-6 cm long shoots of Masson pine are selected. The tissue-cultured seedlings were used as the ear-picking mother plant. On November 28, 2013, the ear-picking mother plant was planted in the seedbed at a density of 50 cm × 50 cm.

[0030] After the seedlings are planted, use a mass concentration of 1.5‰5N-30P-7K high-phosphorus compound fertilizer aqueous solution to spray the leaves every 12 days, and trim the seedling height to 10-12 cm on April 24, 2014; Mass concentration 1‰24...

Embodiment 3

[0033] In October 2012, we chose a relatively flat and open area with a soil pH value of 6.6, a soil layer thickness of 65cm, and a loose, convenient irrigation and drainage area as a nursery. Weeds, stones, and debris were removed, and the broken soil was leveled. spare. Cultivate for 3 and a half months, the seedling height is 20 cm, the average ground diameter is 4.2 mm, the growth is strong, and the masson pine tissue culture seedlings without diseases and insect pests are truncated. After truncating, more than 4 sprouts are selected, and the masson pine with 6-7 cm long buds is selected. The tissue-cultured seedlings were used as the mother plant for ear picking, and on November 30, 2014, the mother plant for ear picking was planted in the seedbed at a density of 50 cm × 50 cm.

[0034] After the seedlings are planted, spray the leaves with a mass concentration of 2‰5N-30P-7K high-phosphorus compound fertilizer aqueous solution every 14 days, and trim the seedling height ...

Abstract

The invention discloses a method for building a cutting orchard with Pinus massoniana Lamb. tissue culture seedlings. The method comprises the procedures of orchard selection, soil preparation, nursery stock preparation and field planting, annual management and cutting orchard management after field planting. The method comprises the following specific steps: selecting an orchard and performing soil preparation for later use; performing tissue culture on germinating robust Pinus massoniana Lamb. free from plant diseases and insect pests, and planting in a seed bed; after field planting, performing water and fertilizer management the same year; and performing fertilization and plant disease and insect pest prevention and control management on the cutting orchard to obtain scions which grow robustly and are super-vital, uniform in thicknesses and easy for cutting survival. The technical problems of poor cost of the current Pinus massoniana Lamb. tissue culture seedlings, poor rejuvenation function of stock plants in cutting rapid propagation, quick physiologic aging of the scions, poor vitality, difficulty for cutting survival and the like are solved. The method for building the cutting orchard with Pinus massoniana Lamb. tissue culture seedlings has the advantages of short stock plant culture period, high cutting survival rate, and good economical benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and relates to tissue culture seedling raising technology, in particular to a method for constructing an ear-picking nursery by using tissue culture seedlings of Pinus massoniana. Background technique [0002] Masson pine ( Pinus massoniana Lamb.) belongs to Pinaceae (Pinaceae) Pinus subfamily (Pinoideae) Pinus ( Pinus L.) Dimensional vascular Pinus subgenus ( Subgen Pinus ) plant, which is a dual-purpose tree species unique to native afforestation in subtropical regions of my country. As a tree species with high comprehensive utilization value and broad promotion prospects, masson pine can not only be used to produce three-board, papermaking and chemical fiber industrial manufacturing, but also can be used to produce industrial raw materials such as rosin and turpentine. In recent years, with the intensification of contradictions between people's growing living needs and the shor...
