Problems solved by technology

Since the seeds of Bletaceae are hard seeds, there are many factors in the natural germination process that lead to a low success rate of seed germination, and the natural germination of seeds is far from being able to offset the reduction in resources
However, in traditional production, the germination rate of basilica seeds without any hormone treatment is often only about 50%, and the germination time is late and the emergence of seedlings is irregular, which limits the large-scale planting of basilica

Embodiment 1

[0027] Choose a leeward, sunny place with good water permeability to build a seedbed, fill the seedling container with nutrient soil, and place it neatly on the seedbed. One day before sowing, use potassium permanganate with a weight concentration of 0.2% to disinfect the nutrient soil. Choose common cork oak seeds, soak them with clear water for 1 day before sowing, then dress the seeds with 0.2% carbendazim solution by weight, cover with plastic film for insecticide, and then store the seeds with wet sand. The volume ratio is 2:1. After the seeds are stored and germinated, they germinate from February to March of the next year. The germinated seeds are taken out from the wet sand and sowed in a seedling container filled with nutrient soil. ~2cm thick. The nutrient soil is prepared by mixing uniformly according to the volume ratio of raw materials: red soil: humic soil = 1-2:1. The seedling-raising container adopts a degradable non-woven seedling-growing bag of 8cm×15cm. S...

Abstract

The invention discloses an asexual rapid reproduction method of lithocarpus craibianus Barn. The method comprises the steps of scion collection, grafting time selection, grafting and management after grafting. A quercus variabilis BI container seedling is selected to serve as a rootstock, semi-lignified and lignified branches which are healthy, strong and free of diseases and insect pests are pruned from a lithocarpus craibianus Barn. seed tree to serve as scions, grafting is conducted through a cleft grafting method, management after grafting is conducted, and lithocarpus craibianus Barn. grafted seedlings obtained in spring of the next year can be moved out of a nursery for afforestation. The asexual rapid reproduction method of the lithocarpus craibianus Barn. is a breakthrough of an asexual reproduction technology of the lithocarpus craibianus Barn., quercus variabilis BI rootstock is utilized for grafting reproduction, a large number of quercus variabilis BI container seedling nursery stocks maintaining the good economic character of a female parent are rapidly reproduced, and roots of the nursery stocks are developed; according to seedlings of the lithocarpus craibianus Barn., by means of the advantage characteristic that the quercus variabilis BI rootstock has strong adaptive capacity to natural environments which are dry, barren and the like, rapid healing between the scions and the rootstock can be achieved, young sprouts can be obtained, the obtained young sprout grow rapidly, high-quality, efficient and rapid development of the lithocarpus craibianus Barn. is facilitated, and good economic benefit, social benefit and ecological benefit are achieved.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and relates to a method for rapid vegetative propagation of basilica. Background technique [0002] Bai Suike ( Lithocarpus craibianus Barn. ), a tree of the family Fagaceae (Lithocarpus), arbor, up to 20 meters. There are brownish-yellow or off-white wax scales on the current year's branches, leaf backs and female inflorescence axes. Leaf leathery, ovate or ovate-elliptic, 12-19 cm long, sometimes shorter or longer, 4-7 cm wide, thinner and wider, apex long pointed, base shortly pointed to broadly cuneate, margin entire, lower segment of midrib The leaf surface is thick, with about 8-12 veins, and the leaf surface is often in a groove-like depression, and the branch veins are not obvious or faintly visible. The leaf surface of the young leaves is often oily and shiny after drying, and the biennial leaves are dark; the petiole is long 1-2.5 cm. Male spikes axillary, rarel...
