Embodiment 1

[0055] The cultivation technology of half-year-old high-fat masson pine seedlings in nutritional bags comprises the following steps:

[0056] (1) Nursery land selection: choose to build a nursery in a sunny area in the south of the subtropical zone, where the terrain is flat, irrigation and drainage are convenient, and the leeward is sunny, in the Xinyi area of ​​Guangdong;

[0057] (2) Nursery land preparation: the old land, after the land preparation, sprinkle with lime and then spread 5cm thick yellow heart soil;

[0058] (3) Nutrition bag selection: use a film bag with a size of 5×12cm and holes around it;

[0059] (4) Preparation of nutrient soil: Use 25% of fire soil, 73% of pine forest surface soil and pure yellow heart soil, add 2% of calcium superphosphate that has been retting and decomposed, after fully crushing, mix and sieve before use;

[0060] (5) Bagging: Arrange in the shape of "品", 20 pieces in each row, each furrow is about 100cm wide and 15m long; when fil...

Embodiment 2

[0078] The cultivation technology of half-year-old high-fat masson pine seedlings in nutritional bags comprises the following steps:

[0079] (1) Nursery site selection: choose to build a nursery site in a sunny area in the south of the subtropical zone, with flat terrain, convenient drainage and irrigation, and a place leeward to the sun, in the Yangchun area of ​​Guangdong;

[0080] (2) Nursery land preparation: When preparing new land, it should be flat and have unobstructed drainage channels to achieve uniform irrigation and no water accumulation;

[0081] (3) Nutrition bag selection: use a film bag with a size of 5×12cm and holes around it;

[0082] (4) Preparation of nutrient soil: Use 30% of fire soil, 68% of pine forest mountain topsoil and pure yellow heart soil, add 2% of retting and decomposed superphosphate, after fully crushing, mix and sieve before use;

[0083] (5) Bagging: Arrange in the shape of "品", 20 pieces in each row, each furrow is about 100cm wide and ...

Abstract

The invention relates to a method for cultivating semi-annual high-rosin pinus massoniana lamb seedlings in nutrient bags, and belongs to the field of technologies for cultivating forest tree seedlings. The method includes steps of selecting garden land; preparing the garden land; selecting the nutrient bags; preparing nutrient soil; filling the nutrient soil in the bags; sowing seeds and accelerating germination of the seeds; transplanting seedlings into the bags; managing the seedlings; discharging the seedlings out of gardens. The method particularly includes that the nursery garden land is built in south regions of the south subtropics or tropical regions with sufficient sunlight, and the seeds and fine river sand are sufficiently and uniformly mixed with one another and are scattered in seedling beds; the nutrient soil is filled in the bags, then the seedlings are transplanted into the bags when seed cases of the seedlings are about to fall or soon after the seed cases of the seedlings just fall off, a series of seedling management measures including water management, fertilization and pest control are carried out, and then the seedlings can be discharged from the gardens when the heights of the seedlings reach 15cm at least and the ground diameters of the seedlings reach 0.15cm at least. The method with the technology has the advantages of short seedling cultivation period, low cost, neat seedlings and high survival rate.

Description

technical field [0001] The invention relates to a method for cultivating masson pine seedlings, in particular to a method for cultivating half-year-old high-fat masson pine seedlings in nutritional bags, and belongs to the technical field of tree seedling cultivation. Background technique [0002] Pine resin is an important chemical raw material, and its deep processing is used in all aspects of production and life. At present, the annual output of turpentine in the world is about 1-1.2 million tons, of which the annual output of rosin in my country reaches 400,000 tons, accounting for more than one-third of the world's total output, and the annual foreign exchange earning through export reaches hundreds of millions of dollars, accounting for about 40% of the world's trade volume. In my country, more than 90% of pine resin is produced from Masson pine, and Masson pine occupies a pivotal position in my country's turpentine industry. [0003] Masson pine ( Pinus massonia...
