Problems solved by technology

[0004] The early studies on the increase of leaves and fruits of Pingou hybrid hazel were mainly based on the application of macronutrient fertilizers. In recent years, researches have focused on spraying macronutrient fertilizers or plant growth regulators on leaves and pruning, while micronutrients have been applied. Effects of elements on seed setting and kernel quality of Pingou hybrid hazel have not been reported yet

Embodiment 1

[0099] A planting method of hazel, comprising the following steps:

[0100] (a) Plant hazel: prepare Pingou hybrid hazel "Dawei" variety seedlings, use Liaozhen No. 7 as pollination tree, the seedlings have 15 lignified roots, root length is 20cm, and seedling height is 80cm, the main plant species The ratio to pollinated trees is 4:1;

[0101] Before the germination of the hazel tree, the planting hole is dug in the autumn of the year before the planting. When digging the hole, the topsoil and mellow soil are placed on one side, and the bottom soil is placed on the other side. The diameter of the planting hole is 47cm and the depth is 48cm. ;Cut off the roots of the seedlings that are more than 10 meters away from the rhizome, dip them in water-retaining agent and then plant them. The distance between plants and rows is 2.2m, and the distance between plants and rows is 3.8m; The filling depth is 28cm, and then fill the upper part of the planting hole with surface mellow soil...

Abstract

The present invention belongs to the technical field of fruit tree cultivation, and especially relates to a plantation method of hazel trees. The plantation method of hazel trees comprises the following steps of applying zinc fertilizer and boron fertilizer at a leaf-expansion period or a full-blossom period of the hazel trees, and obtaining hazelnuts at a harvesting period. The plantation methodof hazel trees specifically comprises the following steps of (a) planting the hazel trees, preferably, the hazel trees being selected from C.heterophylla*C.avellana; (b) applying the zinc fertilizer and boron fertilizer at the leaf-expansion period or the full-blossom period of the hazel trees, an interval between the application time of the zinc fertilizer and boron fertilizer being at least 24 hours; (c) performing soil management and pest control, and harvesting the hazelnuts. According to the plantation method, the fruit yield of the hazel trees can be increased, fruit quality can be improved, the net photosynthetic rate of leaves of the hazel trees is increased by 59.59%, the weight of single fruit is increased by 2.52%, the weight of kernel is increased by 3.16%, the kernel percent is increased by 2.22%, and the phosphorus content of the leaves is increased by 60.52%.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for planting hazel trees. Background technique [0002] Hazel is a plant of the genus Corylus in the family Betulaceae, and is an important woody oil tree species with high economic value. In the 1980s, Liaoning Provincial Institute of Economic Forestry and other units carried out the research on interspecific hybridization between flat hazel and the introduced European hazel (Corylus avellana), and bred flat European hybrid hazel (C.heterophylla×C.avellana )New varieties. [0003] Due to the short period of large-scale cultivation, only a small amount of Pingou hybrid hazelnut can be commercialized at present, and the orchards in most areas are in the young stage, and there are problems such as low cultivation technology and irregular tending management, which restrict the improvement of the economic benefits of hazelnut orchards. Fertilization is an im...
