Embodiment 1

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

[0037] In July, the selected masson pine tissue culture seedlings were first planted in a seedling raising container equipped with a seedling substrate; during planting, avoiding nest roots or damaging the seedlings, compacting the seedling substrate, and drenching enough root water; wherein, the The seedling substrate is made of coconut bran, peat soil, pine forest topsoil, yellow heart soil and 6N-38P-9K high-phosphorus compound fertilizer according to a mass ratio of 2:1:4:1:0.5. The seedling container is 15 cm×15 cm non-woven nursery cup. Within 1 month after initial planting, spray with a 0.3% mass concentration of 6N-38P-9K high-phosphorus compound fertilizer aqueous solution for foliar fertilization every 7 days; follow conventional daily management...

Embodiment 2

[0051] In 2014, selected the masson pine tissue cultured seedlings cultivated for 5 months with a ground diameter of 4.3 to 4.4 mm, a seedling height of 26 to 27 cm, good growth, strong, and well-developed roots as the mother plant.

[0052] In August, the selected masson pine tissue culture seedlings were first planted in a seedling raising container equipped with a seedling substrate; during planting, avoiding nesting or damaging the seedlings, compacting the seedling substrate, and drenching enough root water; wherein, the The seedling substrate is made of coconut bran, peat soil, pine forest topsoil, yellow heart soil and 6N-38P-9K high-phosphorus compound fertilizer according to a mass ratio of 2:1:4:1:0.5. The seedling container is 15 cm×15 cm non-woven nursery cup. Within 2 months after initial planting, spray with a 0.4% mass concentration of 6N-38P-9K high-phosphorus compound fertilizer aqueous solution for foliar fertilization every 8 days; follow conventional daily man...

Embodiment 3

[0066] In 2015, select the masson pine tissue culture seedlings cultivated for 6 months with a ground diameter of 4.4 to 4.5 mm, a seedling height of 26 to 27 cm, a good growth, a strong, and a developed root system as the mother plant.

[0067] In August, the selected masson pine tissue culture seedlings were first planted in a seedling raising container equipped with a seedling substrate; during planting, avoiding nesting or damaging the seedlings, compacting the seedling substrate, and drenching enough root water; wherein, the The seedling substrate is made of coconut bran, peat soil, pine forest topsoil, yellow heart soil and 6N-38P-9K high-phosphorus compound fertilizer according to a mass ratio of 2:1:4:1:0.5. The seedling container is 15 cm×15 cm non-woven nursery cup. Within 2 months after the initial planting, spray with a 0.5% mass concentration of 6N-38P-9K high-phosphorus compound fertilizer aqueous solution for foliar fertilization every 10 days; follow conventional ...

Abstract

The invention provides a method for improving pinus massoniana cutting stock plant ear production. The method includes the steps: stock plant selection; stock plant planting; trimming and pruning; stock plant management and protection. The method particularly includes the steps: selecting cultivated pinus massoniana tissue culture seedlings which are good in growth vigor, thick, strong and rich inroot system as stock plants; initially planting the pinus massoniana tissue culture seedlings in a seedling culture containers with seedling culture substrates, and managing the seedlings after initially planting; cutting the tops of the stock plants, planting the stock plants on a prepared seedling bed, managing the stock plants after planting; trimming and pruning the stock plants when buds ofthe stock plants grow to 5-6cm; performing moisture management and protection, nutrient management and protection, soil management and protection, diseases and insect pests control and updating on the stock plants. The stock plants cultivated by the method are high in survival rate, have luxuriant branches and leaves and thick and strong stems and nutritiously and vigorously grow, the service lives of the stock plants are effectively prolonged, yield, quality and activity of scions are greatly improved, cutting rooting rate and cutting survival rate are increased, nursery stock quality is improved, and pinus massoniana cloning nursery stock breeding effects are improved.

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 the ear yield of a cutting mother plant 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 regions across the country, including Guangxi, Fujian, Yunnan, Guizhou, Sichuan, and Zhejiang. It has a wide range of uses, not only as an excellent building material, but also as an 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 increasing living needs, the shortage of wood resources and the gradual exhaustion of non-renewa...
