A method for regulating the germination growth and defoliation of red maple

Abstract

The invention provides a method for controlling the germination growth and defoliation of maple, which includes the following contents: 1) spring germination and defoliation treatment: normal germination and growth in spring, without any treatment, until late April to early May, spraying wet defoliation agent to fall off Leaves; 2) Germination and leaf fall treatment in summer: Spray germination-promoting and color-enhancing agent from early May to early June to promote red maple germination, and spray defoliant to shed leaves from late July to early August; 3) Germination in autumn Treatment with fallen leaves: start spraying the germination-promoting and coloring agent in early September to promote the germination of red maple, and start spraying the defoliant in late October to shed leaves; 4) Germination and leaf fall treatment in winter: after the leaves fall off in November, spray Wet germination color enhancer, spray wet plant antifreeze after germination, and start spraying wet defoliant to shed leaves in mid-January. The invention enables Japanese red maple to germinate and grow throughout the year, and solves the time and expense of manually picking leaves, saves labor and time, leaves fall quickly and neatly, has low production cost, and has strong operability.

Description

technical field [0001] The invention belongs to the technical field of colorful-leaf plant cultivation, and in particular relates to a method for regulating the four seasons germination growth and leaf fall of Japanese red maple. [0002] technical background [0003] Japanese red maple is a deciduous small tree or shrub belonging to the genus Chrysanthemum, which was introduced into China from Japan in the 1990s. It is a very beautiful foliage plant. Under normal growth conditions, it germinates and grows fiery red in spring. The leaves of Japanese red maple are the most beautiful and have the highest ornamental value. The leaves turn green in summer, and the leaves dry up and fall off in late autumn and early winter and go dormant, greatly reducing their ornamental value.

Problems solved by technology

[0004] For Japanese red maple's multi-year germination control technology, in 2016 Zhong Que et al. published "Japanese red maple's multi-year germination control technology test" in "China Forestry Industry". In addition to growth, in autumn, the measures to promote germination are carried out after picking leaves manually. In fact, it can only be regarded as two germinations and growths in a year, not to mention many times.

There are technical deficiencies in this experiment: one is that the Japanese red maple defoliation technology adopts manual leaf picking, which is only suitable for a small amount of potted Japanese red maple and is not suitable for large-scale planting. Picking is not clean and tidy, which will affect the uniformity of germination and viewing effect, especially for the Japanese red maple planted in rural tourist attractions.

Secondly, under open field cultivation conditions, in winter, the leaves of Japanese red maple will naturally dry up and fall off, and then enter a dormant state. Under natural conditions in winter, chemical budding methods are used. Low temperature will also reduce plant resistance, cause injury or death, and affect germination and growth in the coming spring

Only by transferring the potted plants into the greenhouse and keeping the temperature of the greenhouse above 15°C requires better warming equipment and facilities to ensure growth. The high cost of potted plants is not suitable for promotion and application in tourist attractions and has no market prospects.
