Environmental-protection Chinese populous lasiocarpa and planting method thereof

Abstract

Disclosed are a hybrid populous lasiocarpa and a planting method thereof. The hybrid populous lasiocarpa is obtained by hybridizing and breeding Chinese white poplar and European red poplar and named as environmental-protection Chinese populous lasiocarpa. The planting method comprises the steps of seedling, cottage, transplanting in forest establishment regions, maintenance and forest establishment. The e environmental-protection Chinese populous lasiocarpa has a timber cycle of 3-6 years and has the advantages of being hermaphrodite, flowerless, seedless, saline-alkaline-resistant, wind-resistant, disease-resistant, pest-resistant, wide in application range, rapid in growth, harmless to air and soil, high in timber yield and the like, thereby being capable of serving as environmental greening, city and road border tree or windbreak as well as economic tree for large-area mountains or hills. The good environmental effects, the high timber yield, the good material quality and the comprehensively-applicable economic value can generate high social and economic benefits.

Description

technical field [0001] The invention relates to a poplar seedling raising and planting technology. It is mainly a new poplar variety-"Chinese big-leaf environmental protection poplar"--"Chinese big-leaf environmental protection poplar", which is mainly obtained by cross-breeding Chinese white poplar and European red poplar. Seedling raising and planting techniques of "Chinese Big-leaf Environmental Protection Poplar" with the advantages of resistance to diseases and insect pests, wide adaptability, rapid growth, no harm to air and soil, and large yield. Background technique [0002] The planting of poplar has a long history in my country, and its varieties reach more than 100 kinds. However, the common disadvantages of the original varieties are: 1. The distribution range is narrow: non-heat-resistant and cold-resistant varieties are only suitable for the Yangtze River Basin and the north. 2. Blooming and floc formation every year: the flocs produced pollute the environmen...

AI Technical Summary

Problems solved by technology

However, the common disadvantages of the original varieties are: 1. The distribution range is narrow: non-heat-resistant and cold-resistant varieties, only suitable for the Yangtze River Basin and the north area

3. There are many pests and diseases: poplar canker and black spot are frequent, and natural enemies include longhorn beetles and thorns; 4. The growth period is long and the yield rate is low: the growth period of poplar is generally more than 7 years, and the yield per mu Only 50-60m 3

5. Poor salt-alkali resistance and wind resistance: the soil pH is strictly required (6-8), and the land with heavy saline-alkali cannot be planted; due to poor root development and low trunk fiber content, it is easy to grow in 6-7 strong winds break or fall over

These disadvantages have greatly restricted the large-scale planting of poplars and their use as urban greening trees and street trees.
