Corylus heterophylla is a cross between Corylus heterophylla and China native wild Corylus heterophylla, with high survival rate, large fruit, high yield and high kernel rate. According to the author's years of planting experience, the cultivation and management techniques of Corylus heterophylla were analyzed and summarized.

1.

1. Selection of cultivation site: Tree species have strong adaptability and can be planted in both sandy land and flat land. The land has good water conditions and good drainage, especially in weak alkaline and neutral soil. Taboo: Do not plant in low-lying areas and places with serious soil hardening.

2. Seedling raising: asexual propagation technology and grafting method can be used for cultivation, that is, layering and root separation method, also known as vertical layering method.

3. Planting tree species: choose to plant in the first half of April after Tomb-Sweeping Day. Generally, the planting density of hazelnuts is between three and six meters. Before planting, soak the roots of seedlings with rooting powder for about one day. When planting, the roots should be spread out, not deeply planted.

Second, the management technology of Corylus heterophylla

1, plastic pruning In order to make the large fruit hazelnut tree bear fruit and yield early, it is necessary to carry out plastic pruning, which is generally divided into summer pruning and winter pruning. In the process of shaping and pruning, we should pay attention to proper pruning to shape the tree, not excessive pruning.

2. The management of soil and land should be ploughed frequently to keep the soil soft and maintain a certain fertility. In the young stage of hazelnut tree, some small plants can be planted properly and the soil can be turned frequently, which can make the root system of the tree extend underground and is conducive to growth.

3. Rational fertilization and seedling cultivation should pay attention to diligent management. Without fertilizer, the growth of saplings will be limited. If fertilization is excessive, the seedlings will be overfertilized, which will affect the yield. Only by reasonable fertilization can trees grow sturdily and mature as soon as possible.

4. The reasonable irrigation of irrigation seedlings should be determined according to the needs of different periods, and ensuring soil moisture can improve the survival rate. During the growing period of Corylus heterophylla, it can be irrigated three or four times a year. When there is too much water, artificial drainage should be carried out.

5. Pest control Hazelnut has strong pest control ability, and powdery mildew is the main need to be controlled. Insecticide can be sprayed in May and June to control pests and diseases.
