Problems solved by technology

[0003] Because the cost of cutting seedling cultivation is too high, the cultivation of American red maple is mostly cultivated by seeds, but the male plants of American red maple generally bloom earlier and have less flowering; while the female plants generally bloom later, resulting in a low conventional seed setting rate; and The American red maple plant is relatively tall, the pollen is small, the amount of pollen is small, it is difficult to collect, and the survival of hybridization after pollen preservation is low

Embodiment 1

[0016] A kind of method for promoting the hybrid survival of American red maple of the present embodiment is characterized in that, the method for promoting the hybrid survival of American red maple comprises the following steps:

[0017] (1) Treatment of male plants: (a) Cut off flower branches that have just germinated flower buds on male plants of American Red Maple in early March. The length of flower branches is more than 50 cm and the diameter is more than 1.5 cm; Wrapped and soaked in a closed container with maple flowering delay liquid, the maple flowering delay liquid is: 2000ppm green fresh element + 2% sucrose + 2% iso-VC sodium water compound solution, placed in a 3-5 degree (c) Take it out after one week, put it in a place with scattered light, use 1000 times of Huaduoduo No. 2 for hydroponics and collect pollen;

[0018] (2) Treatment of female plants: Spray maple flowering promotion liquid on female plants in mid-February. The flowering promotion liquid of maple...

Abstract

The invention relates to a method for promoting the survival of hybrid acer rubrum. The method comprises the following steps: (1) processing a male plant; (2) processing a female plant; and (3) hybridizing. Through the adoption of the method disclosed by the invention, the male parent flowering phase is delayed, and the female parent flowering phase is advanced, so that the interspecies hybrid success rate of the acer rubrum in different flowering phases is greatly improved.

Description

technical field [0001] The invention relates to a method for promoting hybrid survival of American red maple, in particular to a method for promoting hybrid survival of American red maple varieties in different flowering stages. Background technique [0002] American red maple is native to the east coast of the United States. It is a large deciduous tree that grows fast. The adult tree is 12-18 meters high and the crown width is 12 meters. It can adapt to the growth of various soil types. It blooms in spring and is red because of its autumn color. It is eye-catching and has a neat canopy. It is widely used in parks, residential areas, and streets. It can be used for landscaping and street trees. It is deeply loved by people. It is one of the ideal and rare tree species introduced in recent years for beautifying and greening urban gardens. [0003] Because the cost of cutting seedling cultivation is too high, the cultivation of American red maple is mostly cultivated by seeds...
