Seedlings of fruit trees for winter storage

Winter storage of fruit tree seedlings is a technique commonly used in production. Especially after entering the winter, most of the seedlings enter the hibernation state, and some seedlings are not tolerant to cold. Some seedlings have sufficient water and fertilizer during the growth process. The upper shoots are not completely lignified, and if they do not leave the plants, they are easily dried ( Commonly referred to as pumping strokes), and some seedlings are arranged to make land plots. In the event of these conditions, winter pupation storage can avoid dead seedlings. The relevant technology is introduced as follows:

1. The time is usually after the leaves have been completely defoliated, but the soil is not frozen before it is better. Early seedlings did not enter the hibernation period, too late to freeze too hard to raise the seedlings, or some seedlings have been frost damage.

2. Start the seedlings 7 to 10 days before the seedlings are planted (the clay land can be advanced, the sand land can be a few days later), and pour the nursery over again, and then raise the seedlings when the soil in the nursery is suitable for dry and wet conditions. Seedlings are good, but also save labor and labor, and the roots of seedlings are more complete, lay the foundation for the survival after the planting.

3. Digging trenches Choose a flat place where the leewards are sunny and do not accumulate water. Dig a deep trench in the north-south direction. The width of the trench is generally 2.5 meters. The length of the trench is determined by the number of seedlings. The depth of the trench is based on the height of the seedlings. It is generally recommended that three-quarters of the height of digging seedlings be better. If the height of seedlings is 1 meter, the ditch depth should be 75 cm.

4. If the seedlings are planted from the same day (the seedlings must not be taken out several days in advance to prevent air drying), they should be half lying in the false planting ditch at an angle of 30 to 40 degrees with the ground. Overlap and put down in the form of a whole bundle, put a layer of it and then use wet sand or sand (the dry humidity is hand-crushed into a group, fall out of the ground can be broken and broken) buried, just cover it, and then Use the same method to place the second and third layers.

After the seedlings have been planted, some sand and soil shall be covered in the uncovered areas. The thickness of the cover soil shall not be too deep. After all of the above are completed, some corn stalks shall be used to cover the top of the soil. When the seedlings are planted after the spring of the following year, they shall be Dig with planting.
