Embodiment 1

[0022] Below in conjunction with embodiment the present invention is further described.

[0023] A seedling raising method for improving the survival rate of black locust grafting, comprising the following method steps:

[0024] (1) Select the rootstock: when the leaf buds germinate in the first and middle days of April, select 1-year-old black locust seedlings as the rootstock, and the rhizome is more than 1.0 cm thick.

[0025] (2) Collection and preservation of scions: Collect scions from late February to early March, and select healthy and pest-free Robinia pseudoacacia varieties or clones as scions. 1.0cm. After harvesting, store them in a pit in a cool and leeward place, and bury them with wet sand.

[0026] (3) Grafting: Grafting begins when the leaf buds germinate in the first and middle days of April. The skin connection method is divided into 4 steps:

[0027] A. Cutting the scion: choose a plump bud, and cut it into a 2cm-long horse-ear-shaped slope at the botto...

Abstract

The invention discloses a seedling growing method for increasing robinia pseudoacacia grafting survival rates. The seedling growing method includes steps of rootstock selecting, branch selecting, scion cutting and processing, grafting, post-grafting managing and the like. A main grafting process includes separating bast of rootstock from wood of the rootstock; inserting scions into the rootstock; binding grafting positions by jute husk; fixing the rootstock and the scions by wet mud; ultimately earthing up the rootstock and the scions by moist and loose soil to form soil piles. The seedling growing method has the advantages that the temperatures and the humidity of contact positions of the rootstock and the scions can be improved, so that healing can be accelerated; combination of the rootstock and the scions can be reinforced, so that the wind-breakage resistance can be improved, the survival rates can be increased by 12% at least, the seedling growing method is easy and convenient to implement, is economical and environmental friendly and has an obvious economic benefit, unbinding can be omitted, the grafting operation labor intensity can be relieved for seedling farmers, and seedlings are convenient to manage; the rootstock and the scions can be healed fast, can be combined with one another firmly and can germinate quickly, the seedlings can neatly come out of the earth, can grow robustly, are high in survival rate and are wind-breakage-resistant, and the seedling growing method is favorable for breeding and popularizing novel varieties of robinia pseudoacacia and has an obvious social benefit.

Description

technical field [0001] The invention relates to the field of propagation of black locust, in particular to a seedling raising method for improving the grafted survival rate of black locust. Background technique [0002] Black locust (Robinia pseudoacacia L.) is a species of high-quality timber forest, firewood forest and shelter forest in temperate regions, and it has both landscape, nectar and feed purposes. The traditional propagation method of Robinia pseudoacacia is to use seeds to raise seedlings, but grafting technology is commonly used in the propagation of fine varieties or clones of Robinia pseudoacacia, and the most widely used grafting technology is grafting seedling raising technology. Cutting seedling grafting is often carried out in spring. Due to the large climate change in spring, it is often affected by factors such as spring cold, drought, and strong wind after grafting. high cost. Contents of the invention [0003] The purpose of the present invention ...
