The cultivation and management techniques of hazelnut trees are as follows:
1. Selection of seedlings and cultivation of seedlings. A strong plant is more resistant to pests and diseases and will last longer than a weak plant. Therefore, the benefits obtained by farmers are also higher. If we sow and raise seedlings, the quality of the selected seeds should be high-yielding and resistant to diseases and insect pests. If you choose to transplant seedlings, you should choose high-yielding seedlings that are relatively strong and free from pests and diseases.
2. Artificial pollination.
1. Reasonable configuration. Hazelnuts can bear fruit only after the male and female flowers are arranged. But the hazel trees are relatively tall, and there is a certain distance between the flowers. The effective pollination distance for hazelnuts is only about 18m, so before planting, in order to increase the pollination rate, we must arrange the pollination ratio of male and female fruit trees. The ratio of female to male plants is 4:1. For each garden, we select 3-4 main cultivation qualities and plant 3-4 rows of each variety so that they can pollinate each other.
2. Manual help. Because the hazelnut male flowers bloom earlier than the female flowers, we have to pick the inflorescences when the stamens are open but have not yet dispersed pollen, and then collect them in a bottle when the pollen disperses. Wait until the pistil opens and tap on it. Carry out proper fertilization. Hazelnuts must have adequate nutrition during their development. Whether it is during the flowering period, fruiting period, or fruit expansion period, we must provide it with sufficient nutrients. This can reduce flower and fruit drop, supplement the nutrients needed for fruit growth, preserve flowers and fruits, and increase fruit enlargement. Fertilization during this period mainly includes urea and potassium-containing fertilizers.
