Problems solved by technology

This requires removing the cutting shed in autumn for seedling hardening, then burying the seedlings for the winter, replanting them in spring, and leaving the nursery after one year of growth. Cuttings require a lot of manpower and take a long time.

specific Embodiment approach

[0029] The method for cultivating seedlings of hazelnut with oblique planting and layering of the present invention, its preferred specific implementation mode is:

[0030] It mainly includes the following steps:

[0031] A. Choose land with flat terrain, fertile soil and high organic matter content;

[0032] B. Whole furrow, the middle of the furrow is low and the sides are high, forming a concave shape;

[0033] C. Adopt the method of oblique planting in the same direction to plant the female parent tree, select seedlings with full buds and no damage, and plant them obliquely in the center of the concave furrow. In the middle and early July, the trunk will be completely placed, and the trunk will be buried shallowly to prevent sunburn;

[0034] D. From late July to early August, topdress the roots once and irrigate them;

[0035] E, in the spring of the 2nd year, before germination, the 1-year-old shoots grown on the main trunk of the buried soil parallel to the ground ar...

specific Embodiment

[0075] In 2013, a 10-acre large-fruit hazelnut nursery was established in Dongjia Town, Jinan, Shandong Province. Seedlings with full buds and no damage were selected. The row spacing of planting plants was 1m×2m, and they were planted obliquely in the center of the concave furrow. The inclination angle is 45°, the root system is buried in the soil 5-8cm, the fixed length is 60cm, and a total of 3,000 mother trees are planted. Start to overwhelm the main trunk around July 10. When overwhelmed, shake it slightly, do not overwhelm it all at once, to prevent the main trunk from breaking. Parallel, then cover a small amount of soil on the main trunk. In the spring of 2014, before the buds germinate, prune the sprouting branches of the main trunk except the top shoots, and leave a pile of about 1cm. After pruning, basically each tree can germinate 10-15 branches. At the end of May and early June, wait for the seedlings to grow to more than 60cm At the same time, remove about 20cm ...

Abstract

The invention discloses a method for slant planting layering seedling culture of a hazel producing large nuts. A concave rectangular piece of land is utilized to slantly plant a seed tree of a hazel producing large nuts; dry sawdust is used to cover bases of sprout tillers, and a technology of earthing on the sawdust is adopted to perform seedling pressing; a special brimming tool and a C-shaped iron ring to brim the bases of the sprout tillers; laying hoses between hazel lines, and reserving water spraying holes in the hoses; by water spraying, it is ensured that the root sawdust is wet, andwater-fertilizer integration irrigation and fertilization are performed through a pipe; a method of combining pinching and trimming of the top is adopted to control upper portion growth, and rooting is promoted; a spring seedling mode is adopted, and the damage to seedlings caused by improper heel-in in autumn is reduced; and plastic bundling ropes of different colors are used to represent different varieties. The land can be effectively saved, the number of seedlings and root quality are improved, manual work can be effectively saved, the efficiency is improved, and the seedling evenness andstandardization are enhanced.

Description

technical field [0001] The invention relates to a method for raising seedlings of hazelnuts with large fruits, in particular to a method for raising seedlings of hazelnuts with oblique planting and layering. Background technique [0002] Hazel is a plant of the genus Corylus in the family Corylaceae. Hazel is an important economic and ecological tree species. It is also known as the "four major nuts" in the world together with walnuts, almonds, and cashews. The large-fruited hazelnut, scientific name Pingou hybrid hazel (C.heterophylla Fisch.×C.avellana L.), is a new variety bred by interspecific cross-breeding with Pingzhen as the female parent and the imported European hazel as the male parent. The excellent genetic traits of the two are concentrated, which not only has the characteristics of strong cold resistance, strong adaptability, and resistance to barrenness, but also has the characteristics of European hazelnuts with large nuts, high kernel yield, and excellent fla...
