Abstract

The invention provides a cutting propagation method for poplar with colorful leaves. The cutting propagation method comprises the following steps: (1) cutting land treatment, namely selecting a sandy loam which is loose in texture, good in drainage and breathable as a cutting land, fertilizing, ploughing and then making a seedbed on the cutting land; (2) cutting slips treatment, namely selecting branches of annual poplar with colorful leaves, cutting the branches into slips with smooth notches; binding the cutting slips, carrying out wet sand storage, taking out the cutting slips before cutting, and soaking in clean water for 4 days; (3) cutting, namely spraying the bed surface before cutting by virtue of a herbicide, cutting in spring, wherein the upper buds of the cutting slips are 1cm higher than the ground during cutting, and spraying the herbicide within three days after cutting; (4) watering and fertilizing, namely thoroughly watering once within half a month after cutting, watering for five times yearly, draining away water in a rainy season, additionally fertilizing a nitrogen fertilizer for three times at the nursery stock fast-growing period, and fertilizing a phosphorus potassium fertilizer at the late growth stage of the nursery stock; (5) removing coppice shoots and reinforcing earth; (6) controlling pests. The cutting propagation method is high in propagation speed, and relatively low in seedling cultivation cost, and can meet the requirements of urban landscape and landscaping.

Description

Technical field: [0001] The invention relates to a cutting propagation method of whole red poplar. Background technique: [0002] Whole red poplar, deciduous tree, single leaves alternate, dioecious, purple-red leaves, a new variety of colorful poplar. As a color-leaved tree species, Quanhong Yang has the characteristics of fast growth and strong adaptability. It is a tall tree with colorful leaves, and its leaves are large and thick, with strong dust absorption. The color of the leaves is red throughout the growth period, and its ornamental value is very high. Therefore, it has great development potential in urban roads and landscaping, which is unmatched by other tree species including colorful leaf tree species. However, the current breeding speed of all red poplar is relatively slow, which can no longer meet the needs of urban landscape and landscaping. Invention content: [0003] The technical problem to be solved by the present invention is to provide a cutting pro...
