Embodiment 1

[0036]In 2013, the masson pine tissue-cultured seedlings with a ground diameter of 4.0-4.2 mm, a seedling height of more than 25 cm, good growth, strong and well-developed root system were selected as the mother plant for 4 months of cultivation.

[0037] In July, the selected Pinus massoniana tissue culture seedlings were first planted in a seedling container equipped with a seedling substrate; when planting, avoid nest roots or damage the seedlings, compact the seedling substrate, and drench enough rooting water; wherein, the The seedling-raising substrate is prepared by uniformly mixing coconut bran, peat soil, pine forest topsoil, yellow core soil and 6N-38P-9K high-phosphorus compound fertilizer in a mass ratio of 2: 1: 4: 1: 0.5; cm × 15 cm non-woven seedling cup. Within 1 month after initial planting, spray 6N-38P-9K high-phosphorus compound fertilizer aqueous solution with a mass concentration of 0.3% every 7 days for foliar fertilization; perform sunshade, supplement ...

Embodiment 2

[0051] In 2014, the tissue-cultured seedlings of Pinus massoniana with good growth, strong growth and well-developed root system were selected as the mother plant, with a ground diameter of 4.3-4.4 mm and a seedling height of 26-27 cm.

[0052] In August, the selected Pinus massoniana tissue culture seedlings were first planted in a seedling container equipped with a seedling substrate; when planting, avoid nest roots or damage seedlings, compact the seedling substrate, and drench enough water for rooting; wherein, the The seedling-raising substrate is prepared by uniformly mixing coconut bran, peat soil, pine forest topsoil, yellow core soil and 6N-38P-9K high-phosphorus compound fertilizer in a mass ratio of 2: 1: 4: 1: 0.5; cm × 15 cm non-woven seedling cup. Within 2 months after initial planting, spray 6N-38P-9K high-phosphorus compound fertilizer aqueous solution with a mass concentration of 0.4% every 8 days for foliar fertilization; perform sunshade, supplement substrat...

Embodiment 3

[0066] In 2015, the tissue culture seedlings of Pinus massoniana, which were cultivated for 6 months, had a ground diameter of 4.4 to 4.5 mm, a seedling height of 26 to 27 cm, were well-grown, sturdy, and developed a root system were selected as the mother plants.

[0067] In August, the selected masson pine tissue culture seedlings were initially planted in a seedling raising container equipped with a seedling-raising matrix; when planting, avoid nesting roots or damage the seedlings, compacting the seedling-raising matrix, and drenching the feet with root-fixing water; wherein, the described The seedling substrate is prepared by uniform mixing of coconut bran, peat soil, pine forest topsoil, loess soil and 6N-38P-9K high-phosphorus compound fertilizer according to the mass ratio of 2: 1: 4: 1: 0.5; the described seedling container is a specification of 15 cm×15 cm non-woven seedling cup. Within 2 months after the initial planting, foliar fertilization was carried out by spra...

Abstract

The invention provides a method for increasing the panicle yield of a cuttage mother plant of Pinus massoniana, which comprises the steps of selection of the mother plant, planting of the mother plant, pruning and shaping, and management and protection of the mother plant. The tissue-cultured seedlings are used as the mother plant, and the tissue-cultured seedlings of Pinus massoniana are initially planted in a seedling container equipped with a seedling substrate, and then managed after the initial planting, and then the mother plant is truncated, and the planting is carried out on the prepared seedbed and after planting Management, when the buds of the mother plant grow to 5-6 cm long, the mother plant will be pruned and shaped, and at the same time, five aspects of water management, nutrient management, soil management, disease and insect pest control and mother plant renewal will be carried out on the mother plant. Management and protection. The mother plant cultivated by the present invention has a high survival rate, luxuriant branches and leaves, strong stems, and very vigorous vegetative growth, which effectively prolongs the service life of the mother plant, greatly improves the yield, quality and activity of spikes, and improves the rooting rate and survival of cuttings. The efficiency and quality of seedlings have improved the breeding effect of masson pine asexual seedlings.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and relates to asexual seedling cultivation technology, in particular to a method for increasing ear yield of cutting mother plants of masson pine. Background technique [0002] Masson pine ( Pinus massoniana Lamb.) is the main afforestation tree species in southern my country. It has been introduced and cultivated in 17 provinces and autonomous regions including Guangxi, Fujian, Yunnan, Guizhou, Sichuan, and Zhejiang. It has a wide range of uses, not only as excellent building materials, but also as excellent papermaking and Man-made fiberboard raw materials can also be used to produce chemical products such as rosin and turpentine, which play an extremely important role in my country's national economic construction. With the intensification of contradictions between people's growing living needs and the shortage of timber resources and the gradual depletion of non-renewable resources...
