Comprehensive management and cultivation method for promoting rapid propagation of poplar seedlings

Abstract

The invention discloses a comprehensive management and cultivation method for promoting rapid propagation of poplar seedlings. The comprehensive management and cultivation method comprises the following steps: (1) selecting sandy loam or light loam with flat terrain and loose soil as a seedling nursery field, applying base fertilizer, deep ploughing, flattening, sterilizing, watering, air-drying, shallow hoeing and loosening the seedling nursery field; (2) after land is unfrozen at the beginning of spring and before the flowing of sap, cutting branches of a one-year poplar seedling trunk which grows strongly and develops well, and treating the branches; (3) vertically cutting inserting the lower end of the branch into loose soil of the nursery field, wherein a distance between two adjacent plants is 0.3 to 0.4 m; and (4) watering once two weeks after the branches are inserted, shallow hoeing and loosening the soil after the watering, and carrying out top dressing once two months. The cultivation method is simple, the cultivation period is short, and the rapid propagation of the poplar seedlings can be promoted.

Description

technical field [0001] The invention relates to the technical field of plant planting, in particular to a comprehensive management and cultivation method for promoting rapid propagation of poplar saplings. Background technique [0002] Poplar is the main cultivated forest tree species in my country. Because of its rapid growth, it is very popular among forest farmers in the Central Plains and other regions. The current method of propagating poplar seedlings is mainly to propagate saplings by cutting poplar branches in the field. The branches after the cuttings sprouted shoots and root tillers at the same time. However, due to the rapid rise in temperature during this period, the wind in the environment is relatively strong, and the soil in the field is dry. , the branches of the saplings are easy to lose water, resulting in the death of the pumped new shoots or the germinated root tillers due to drought and dryness, resulting in a low survival rate of the seedlings. The sho...

The current method of propagating poplar seedlings is mainly to propagate saplings by cutting poplar branches in the field. The branches after the cuttings sprouted shoots and root tillers at the same time. However, due to the rapid rise in temperature during this period, the wind in the environment is relatively strong, and the soil in the field is dry. , the branches of the saplings are easy to lose water, resulting in the death of the pumped new shoots or the germinated root tillers due to drought and dryness, resulting in a low survival rate of the seedlings. The shoots and newly germinated roots survived, and the soil temperature and coldness due to watering inhibited the rapid growth of the cuttings or the rapid growth of the roots. When the seedlings stopped growing in late September of that year, there would be about 50% of the seedlings. Poplar saplings that do not meet the national standard of 3,500 mm in height and 25 mm in ground diameter. These seedlings that do not meet the standards must be cut and rooted in the soil in the first ten days of March of the following spring, and then sprout and grow for a period of time. years before they can go out of the nursery for sale. As a result, the propagation and cultivation of the existing poplar saplings is time-consuming, land-consuming, and labor-intensive. Since the failure to go out of the nursery in that year will seriously affect the further reproduction and cultivation of the saplings and the benefits of the enterprise
