Large-fruited hazelnut is a hybrid variety of European hazelnut and wild hazelnut native to my country. This variety has a high survival rate, large fruit, abundant yield, and high kernel rate. The author of this article has many years of planting experience and analyzes and summarizes the cultivation and management techniques of large-fruited hazelnuts. 1. Cultivation of Dacha hazelnut seedlings

1. Select land for cultivation: tree species have strong adaptability and can be planted on sandy soil and flat land. The land must have good moisture conditions and good drainage.

Reasonable fertilization

When cultivating saplings, attention should be paid to regular management. If there is a lack of fertilizer, the growth of the saplings will be restricted. If excessive fertilization is applied, the saplings will be over-fertilized and the yield will be affected. Only reasonable fertilization will Only then will the trees grow sturdily and mature and bear fruit sooner. 4. Reasonable irrigation

Irrigation of saplings should be determined according to the needs of different periods. Ensuring soil moisture can improve the survival rate. During the growth period of large-fruited hazelnuts, irrigation is enough three to four times a year. When there is too much water, artificial drainage is required. 5. Prevention and control of pests and diseases
