Slash pine artificial forest transformation technology

Abstract

The invention discloses a slash pine artificial forest transformation technology. The slash pine artificial forest transformation technology comprises the steps of slash pine forest stand selection standard, a forest stand survey, a single tree survey, forest stand transformation, protection measures and the like. Based on the status quo of slash pine timber forests, forest stands with a good forest stand soil productivity basis are selected, a scientific and reasonable transformation technology is adopted, a single timber wood target is replaced with a multi-purpose forest stand cultivation mode which integrates seedling growing superior tree protection, big-diameter wood cultivation and high-rosin-yield single-plant management, through broad-leaved trees under a forest, the soil productivity is renewed and maintained, the nutrient requirement for timber wood and rosin production is guaranteed, and therefore requirements for different production targets and different interests parties are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of plantation forest reconstruction, and in particular relates to a technology of slash pine plantation reconstruction. Background technique [0002] Slash pine ( Pinus elliottii Engelmann) is native to the southeastern United States. Because of its rapid growth and strong adaptability, it has been widely introduced to many tropical and subtropical countries and regions around the world, and has become an important timber and resin tree species in the introduced areas. Since 1973, my country has successively imported a large number of slash pine seeds from the United States, and carried out introduction, domestication and afforestation in subtropical provinces (regions) such as Guangdong, Guangxi, Hunan, Hubei, Jiangxi, Sichuan, Fujian, Anhui, Jiangsu, Zhejiang, Henan, and Hainan. promotion work. As of 2013, the afforestation area of ​​slash pine in my country has reached 1.34 million hectares, second only...

Problems solved by technology

In recent years, the price of pine turpentine has been rising steadily, and the income from pine resin mining has far exceeded that of timber production. Driven by profits, contracted resin mining behaviors have appeared in slash pine plantations in many areas, regardless of forest species, and even the entire forest of young and middle-aged forests has been cut intensively. Resin, tree vigor and stand decline became common and severely disrupted the wood growth objectives of slash pine timber stands

Moreover, the initial breeding target of slash pine is oriented towards timber production, and forest management measures such as afforestation strains, site selection, and planting density are not designed for pine resin production. lose-lose status quo
