Problems solved by technology

[0004] The traditional methods of cultivating walnut catalpa are mostly skin removal in autumn, sand storage in winter, and germination in spring. The seedlings are restricted by sand storage and seedling sites, and it is difficult for seeds to germinate, and the seedling cycle is long, which wastes a lot of manpower and material resources.

Embodiment Construction

[0032] The conventional seedling raising method of Juglans catalpa, besides seed seedling raising, also has the method of cutting seedling raising and layering propagation. The main root of this kind of seedling is deep and long, and the lateral roots and fibrous roots are very few, so it is difficult to survive when transplanted.

[0033] Cutting seedlings are often used for cuttings of young branches in late spring and early autumn, or cuttings of old branches in early spring with branches of the previous year.

[0034] The cutting substrate is the nutrient soil or river sand, peat soil and other materials used for cutting. It is difficult to obtain ideal cutting substrates for home cuttings due to limited conditions. It is recommended to use the prepared and sterilized cutting substrates provided by this site; medium-coarse river sand is also acceptable, but it should be washed several times with clean water before use.

[0035] Cuttings have extremely high temperature req...

Abstract

The invention discloses a Manchurian walnut seedling culture method. The Manchurian walnut seedling culture method comprises the following steps that peel is removed in autumn, wherein yellow green fruit peel is removed through soaking, then pulp is removed with a ball mill, impurities are removed through washing with water, and seeds are put inside a dry ventilated room for drying in the shade and storage; sand storage processing is carried out, wherein before freezing in autumn in the year before seeding, ditches are dug, and the disinfected seeds are stored with sand; germination is accelerated in spring, wherein 10-15 d before seeding in spring, the seeds are taken out and put into a ball mill, the combination force of seed shells is reduced through vibrating and rubbing, then the seeds are soaked in water, taken out after seed kernels fully absorb water, and tedded, and tedding is finished when most of the seeds crack; seedling culture and afforestation are carried out. Compared with an existing seedling culture technology, the Manchurian walnut seedling culture method is free of the restraint of sand storage and seedling culture fields, the seeds can easily germinate, the seedling culturing cycle is short, seedlings are healthy and strong, and plants are good in growth vigor and high in survival rate.

Description

technical field [0001] The invention relates to a method for raising seedlings of Chinese catalpa. Background technique [0002] Juglans, Juglandaceae Juglans. Main biological characteristics and performance: Deciduous tree, up to 25m, diameter at breast height can reach more than 80cm. The branches are stretched, and the crown is oblate. Bark gray with shallow longitudinal fissures; young branches covered with short tomentose. Odd-numbered pinnate compound leaves are born on the germination bar, up to 80cm long, with 9-17 leaflets, oval or oval. [0003] The conventional method of raising seedlings of Juglans catalpa is spring sowing, selecting large and plump seeds without diseases and insect pests, carrying out germination treatment, and storing them in wet sand. Sow seeds in early May. [0004] Traditionally, walnut catalpa is cultivated by peeling in autumn, sand storage in winter, and germination in spring. The seedlings are restricted by sand storage and seedli...
