Problems solved by technology

This germination method has extensive management and a low seedling rate, and is not suitable for the propagation of rare (precious) varieties or varieties with a low seed setting rate. In addition, the germination is uneven, and it is not suitable for large-scale industrial seedling cultivation, and it is difficult to meet the needs of the market. need

Embodiment Construction

[0016] Harvest mature Acer palmatum fruits in early December, remove the seed wings, and select 300 seeds that are well-developed, plump, large, and free from diseases and insect pests, and put them in seed bags and hang them in a cool and dry place for storage. On March 4th, soak the seeds in clean tap water for 24 hours. It is better for the seeds to fully absorb water; then mix the seeds with vermiculite at a mixing ratio of 1:4, and keep the humidity at 75%, and then put them into a 25×17cm ziplock bag In the process, two holes with a diameter of 0.5 cm are punched on the ziplock bag, and the distance between the two holes is 5 cm. After 20 days, start to observe whether the seeds have cracks, then observe 1 time every 5 days, a small amount of seeds have cracks on the 30th day, and find that more than 1 / 3 of the seeds have cracks on April 10, and sow immediately. 40 days after sowing, the statistical emergence rate is about 90%.

Abstract

The invention discloses a method for low-temperature accelerating germination for acer palmatum seeds, belonging to the field of gardening production. The method comprises: removing the wing of a fruit, then selecting seeds, and dipping the seeds in clean tap water for 24 hours; then, mixing the seed with vermiculite at the ratio of 1:4, and keeping moisture (relative moisture degree is 75%); refrigerating at the temperature of 2-5DEG C; after refrigerating for 20 days, observing whether the seed has a crack; and when more than 1 / 3 seeds have cracks, sowing. The method for low-temperature accelerating germination for acer palmatum seeds can shorten seedling culture period, lower seedling culture cost, improve rate of emergence and is suitable for sowing and breeding valuable breeds or breeds with low maturing rate. In the method, large-scale industrial seedling culture can be carried out so as to satisfy the requirements of markets.

Description

technical field [0001] The invention belongs to the field of horticultural production and relates to a method for accelerating germination of Acer palmatum seeds at low temperature. Background technique [0002] Acer palmatum (Acer Palmatum), also known as Yafeng, belongs to the genus Acer in the family Aceraceae. It is native to the Yangtze River Basin in China, and it is also distributed in Japan and the Korean Peninsula. It is mainly distributed in the provinces of the Yangtze River Basin in China, and it mostly grows in the forest margins or sparse forests of mountains and hills below 1200m above sea level. Acer palmatum is a deciduous small tree, about 8m high, with dark gray bark, purple or lavender-green branches in the current year; light gray-purple or dark purple in perennial branches. Leaves opposite, 7-10 cm in diameter, base truncate, palmately parted, lobes 5-9, usually 7-lobed, lobes ovate-oblong or lanceolate, apex acute or long acute, margins Irregular hea...
