When will the latest hazelnut saplings be planted

Hazelnut, also known as mountain chestnut, is known as one of the four dried fruits, with a wide range of distribution. China is mainly distributed in the northeast, Inner Mongolia, Shanxi and Shandong in the north. It turns out that there are many wild hazelnut forests, and there is also a history of artificial cultivation and breeding for many years. To understand the cultivation of hazelnuts, you can start from the planting time.

1. Planting time

Hazelnuts are planted in northeast Liaoning in April and can be planted throughout April, but Jilin can be planted from April to May, with a more relaxed time. In general, the planting time will not be too tight, either a few days earlier or later. The Hebei area can be planted in late March, and the Yellow River and Yangtze River basin can start planting from February to March. The temperature will rise faster, and it can not be planted more than March. Generally, it is planted in spring and in autumn, but the growth is not as good as that in spring, and there is more management in winter, which is generally not suitable.

2. Seedling raising method

The method of raising seedlings by cutting is the most commonly used method in production, which is generally greenwood cutting. it is difficult for hardwood to take root, and the air humidity is very important during cutting. generally, it should be kept above 95%, that is, the retained leaves will not wither. Air humidity mainly does not rely on watering, to spray more water, atomization spray water. Need a protective environment to cuttage. Keep warm and moisturize.

3. Planting method

After the branches take root, they gradually grow into seedlings, and the seedlings grow gradually, usually for a longer period of time, and then they can be transplanted until the seedlings grow to 1 meter long. at this time, the trunk is relatively hard, easy to plant and manage, and after the growth is vertically stable, it is suitable for later cultivation. The planting density may be thinner, and the space for the saplings to grow should be set aside. The row spacing is about 4 meters, and the plant spacing is about 3 meters. The tree shape of different varieties is different and can be adjusted.

4. Management and maintenance

The main management after hazelnut planting includes watering, fertilization and pruning. Build an irrigated tree plate around the bottom of the tree, a round tree plate about one meter in diameter. Because hazelnut irrigation requires a thorough irrigation. In the first year of planting, it is mainly allowed to grow, and in the second year, when the branches and leaves are plump, they are trimmed and fixed, and the common type is clumpy type, leaving three basal branches directly, and then gradually growing lateral branches. Single stem type, leave the trunk and then leave the lateral branches step by step. Topdressing twice, once in May and once in July, farm manure and compound fertilizer were used together and watered after application.

Hazelnut planting time is probably due to different regions and times, that is, between February and May. According to the regional climate and environment to make adjustments, planting hazelnut should also pay attention to planting methods and some specific management content. These all belong to the planting content.
