A kind of seedling raising method of eastern white pine

Abstract

The invention discloses a seedling raising method of an eastern white pine, which comprises the following steps of: carrying out seedling raising of the eastern white pine in winter by utilizing a greenhouse, prolonging the growth period of the eastern white pine, avoiding low-temperature freezing damage in the seedling period and improving the quality of seedlings; using quartz sand instead of river sand during seed lamination, which is beneficial to improving the working efficiency during dibbling; during seeding, using a degradable non-woven fabric nutrition pot instead of a seedling tray,a plastic nutrition pot or open field seeding, so that the bed changing or transplanting times can be effectively reduced, and the seedling stage does not exist; in the cultivation medium, using decomposed sheep manure instead of other decomposed organic fertilizers, so that the pH value of the soil can be improved, and the soil fertility can be improved; using peat soil instead of garden soil, sothat the organic matter content in the matrix is effectively improved, and the stability of the pH value of the soil is maintained; after the dibbling is finished, spreading a layer of 0.3-0.6cm sawdust, so that the seeds can be prevented from floating upwards during watering. The method improves the breeding quantity and quality of the seedlings and saves the cost.

Description

technical field

[0001] The invention relates to the field of eastern white pine planting, in particular to a method for growing seedlings of eastern white pine. Background technique

[0002] Eastern White Pine ( Pinus strobus ) is a relatively fast-growing tree species in the northern forests of Canada, mainly used in furniture and construction industries. At the same time, the eastern white pine is light-loving and cold-resistant, and has a beautiful tree shape. It is also an excellent greening tree species. It is widely cultivated in Canada and the United States. It is one of the most valuable trees in eastern North America. In 1981, the Jilin Forestry Research Institute introduced the seeds of eastern white pine from the United States and Xiongyue, Liaoning, and carried out the introduction and domestication experiments in the central and eastern parts of Jilin Province. At present, the growth and development are good, it can bloom and bear fruit normally, and the growth...
