Novel rosin increasing agent for pinus massoniana

Abstract

The invention provides a novel rosin increasing agent for pinus massoniana based on systematical research on the influence of plant mineral nutrients, plant growth regulators and pH on the rosin production of the pinus massoniana in order to improve the efficiency of rosin harvesting, ensure the supply of raw materials for rosin industry and promote healthy development of the rosin industry. The rosin increasing agent provided by the invention can significantly improve rosin production and rosin secretion of the pinus massoniana, and the rosin increasing period is two months or more. The rosinincreasing agent is composed of one or more of a plant growth regulator naphthalene acetic acid, brassinosteroid, and plant essential mineral nutrient elements Mg, Zn, Fe, Cu, B, Na, Cl and S.

Description

technical field [0001] The invention belongs to the field of growth promoters, and in particular relates to a novel masson pine fat-increasing agent. Background technique [0002] China is a big country of turpentine production. In the 1990s, the output of rosin was 350,000-400,000 tons per year. In the past 60 years, the cumulative production of rosin was more than 19 million tons, accounting for 60% of the total output of rosin in the world. The annual output value of rosin, turpentine and deep-processed products is about 1.6 billion US dollars, it used to be the second largest forestry industry in China except timber. Masson pine ( Pinus massoniana ) is the main tree species for resin harvesting, and its annual output accounts for more than 90% of the country's total output. As early as the 1850s, China began to use more than 20 kinds of medicaments to increase the production of pine resin. Among them, sulfuric acid or sulfuric acid ointment, chemical resin mining of su...

Problems solved by technology

The secretion of pine resin by pine involves a series of cell physiological and biochemical metabolic reactions, and cell plant mineral nutrients, hormones and pH levels have a greater impact on cell physiological and biochemical reactions, but the effects of cell plant mineral nutrients, hormones and pH on the lipid production of Pinus massoniana are in There is no systematic research in China

[0003] In recent years, with the sustained and rapid development of the domestic economy, the labor cost of resin mining has continued to rise, while the price of turpentine has not increased much, resulting in the lack of enthusiasm of farmers for resin mining. The shortage of raw materials has become the main factor restricting the development of the turpentine industry. Process research stagnated, no breakthroughs
