Problems solved by technology

The results showed that the growth regulator IBA 1000mg·L -1 Treatment 10s and IBA+NAA 1000mg·L -1 Treatment for 10s can effectively promote callus development, but the rooting rate is only 3.3% (Yan Wentao. Research on cutting propagation technology and rooting mechanism of Quercus mongolica twigs. Shenyang Agricultural University Master's Degree Thesis. 2017)

Embodiment 1

[0039] Selection of cutting branches: select strong and sprouting branches of Quercus mongolica roots;

[0040] Preparation of cuttings: cut off the top 10-12cm of the branch as ear material, remove all the leaves except the top, keep 1 / 2 of the area of ​​the top 2-5 leaves, and cut off the rest;

[0041] Rooting agent preparation: ABT rooting powder 1g, water 50mL, 95% alcohol 50mL and talcum powder 200g are mixed to make a paste for later use;

[0042] Cutting treatment: 0.5-1.0cm base of cuttings is quickly dipped in rooting agent, cutting depth is 4-5cm;

[0043] Seedbed construction: the substrate is 20-30cm thick river sand, covered with plastic film greenhouse and 60% shade net, the height of the greenhouse is 2-2.5m, and the width is 4-6m;

[0044] Moisture management: set a fixed time automatic water spray facility. Within 1 month of cutting, spray water 6 times a day, spray water every 2-3 hours from 6:00-18:00, and spray water for 1 minute each time (the water vol...

Abstract

The invention provides a rooting agent for cuttage of Quercus mongolica Fisch.ex Ledeb and application of the rooting agent, and relates to the technical field of cuttage breeding. The rooting agent is prepared from the following components: ABT rooting powder, water, alcohol with the volume concentration being 95% and talc powder, wherein the ratio of the ABT rooting powder to the water to the alcohol with the volume concentration being 95% to the talc powder is 1 g:(30 to 100) mL:(30 to 100) mL:(100 to 400) g. By applying the rooting agent to conduct cuttage of the Quercus mongolica Fisch.exLedeb, the cuttage rooting rate of the Quercus mongolica Fisch.ex Ledeb can be significantly increased and can reach 30%.

Description

technical field [0001] The invention belongs to the technical field of cutting propagation, and in particular relates to a rooting agent for Quercus mongolica cuttings and an application thereof. Background technique [0002] Mongolian Quercus (Quercus mongolica Fisch.ex Ledeb), also known as oak tree, belongs to the genus Quercus in the family Fagaceae. Deciduous tree, tree height up to 30m, DBH up to 60cm. The main root is developed, and the amount of lateral roots is small; the branchlets are thick and hairless; the leaves often gather at the ends of the branches, and are obovate or obovate-oblong, about 7-20cm long. Quercus mongolica is a light-loving tree species with strong adaptability, drought resistance, barren resistance and cold resistance. It is mainly distributed in the Greater and Lesser Xing'an Mountains and Changbai Mountains in the northeast, as well as in Inner Mongolia, Hebei, Liaoning, Shandong, and Shanxi. In the northeast forest area of ​​my country,...
