Novel magnolia zenii seeding and seedling growing method

Abstract

The invention discloses a novel magnolia zenii seeding and seedling growing method. The method includes the following steps: (1), selecting a seed-collection tree; (2), performing seed treatment; (3), selecting nursery land, and performing early land preparation; (4), seeding; (5), performing seedling period management; (6), performing disease and pest prevention and control. In the novel method, seeds are treated and stored at constant temperature during seeding and seedling growing of magnolia zenii for the first time in current production, so that the old problem of seed mildewing and rotting caused by the fact that water content is difficult to control in seed treatment and the old problem that seeds are low germination rate and emergence rate and seedlings are weak due to the fact that physiological after-ripening effect of the seeds is incomplete in the process of seeding and seedling growing of magnolia zenii can be solved. Germination rate of magnolia zenii seeds is increased by more than 75%, and emergence rate is increased by more than 90%; through precision management, the seedlings are reasonable in diameter-height ratio, strong, healthy and high in economic benefit, and nursery outgoing rate of the seedlings is increased. The method is simple, convenient and feasible in operation, little in manpower, low in production cost and easy for popularization and application in production.

Description

technical field [0001] The invention relates to a tree breeding method, in particular to a new method for sowing and raising seedlings of Baohua magnolia. Background technique [0002] Baohua Magnolia ( Magnolia z eni i ) is a plant of the genus Magnolia (Magnolia) in the family Magnoliaceae. Its distribution is limited to Baohuashan National Forest Park in Jurong, Jiangsu Province. It was listed as a national level III endangered species in the 1991 China Plant Red Data Book. It was listed as a second-class endangered species in the list of national key protected wild plants (the first batch) approved by the State Council in August 1999, and was listed as a critically endangered species in the 2004 China Plant Red List. Its trunk is tall and straight, its material is delicate, and it is a good wood; its flowers are large, bright and fragrant, and it is a precious ornamental tree in gardens. In addition, its flowers and fruits can also be used as medicine. At present, Baoh...
