Container seedling-raising method for masson pine

Abstract

The invention provides a container seedling-raising method for masson pine. The method comprises the steps of (1), selecting a nursery field, namely, selecting sandy soils under sufficient sunshine, flat ground and normal draining as the nursery field; (2) leveling the field and preparing a nursery bed, namely, ploughing and raking the nursery field to uniformly crush the soil, applying a disinfector and a herbicide, preparing the nursery bed in north-south direction on the nursery field, covering the nursery bed with a layer of yellow soil, and arranging container bags in order on the nursery bed; (3) preparing nutrient soil, namely, uniformly agitating and mixing the yellow soil, burned soil, mycorrhizal soil, humus, peat soil, vermiculite and fertilizer, and then stacking for 12 days to obtain the nutrient soil; (4) bagging, namely, spraying formalin to the nutrient soil to disinfect, sieving the disinfected nutrient soil, then uniformly mixing with ectomycorrhizae, then feeding into the container bags and compressing; (5) processing the seeds; (6) seeding, namely, seeding in late March, and feeding the seeds into the container bags; (7) performing water and fertilizer management. The container seedling-raising method for masson pine is high in seedling-raising quality and high in rate of survival.

Description

technical field [0001] The invention relates to a container seedling raising method of Pinus massoniana. Background technique [0002] Masson pine (Latin scientific name: Pinus massoniana Lamb.) is a tree with a straight trunk; the outer bark is dark reddish brown, slightly gray, longitudinally cracked, and rectangularly peeled off; the inner bark is maroon reddish yellow; the sapwood is light yellowish brown, very wide, often with green bark; the heartwood Dark yellowish-brown reddish; the annual rings are very obvious and very wide; the wood shoots are shallow and thin, the resin channels are large and numerous, and there are obvious oil rings in the cross-section; the material is medium hard, the texture is straight or oblique, and the structure is medium to thick, when dry The warping is more serious. Masson pine is widely distributed, generally in the lower reaches of the Yangtze River below 600-700m above sea level, above about 1200m in the middle reaches, and below a...
