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:
time
Generally, it can be done after the seedlings have completely fallen. Premature seedlings did not enter the hibernation period. Late freezing did not promote seedlings, or some seedlings had been frozen.
Lifting
In the 7-10 days before the seedlings are planted (the clay land can be advanced, the sand land can be a few days later), the nursery can be poured again and the seedlings can be raised when the soil in the nursery is suitable for dry and wet. It also saves labor and labor, and the root system of seedlings is relatively complete, laying the foundation for the survival after the planting.
Trenching
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 determined by the height of the seedlings. Three quarters are better. If the height of seedlings is one meter, the depth of the ditch should be 75 centimeters.
Implant
Take seedlings from the same day (seedlings should not be taken out several days in advance to prevent air-drying) and lie halfway in the false planting ditch at an angle of 30-40 degrees to the ground. Put the bale down and put a layer of it in place. Use wet sand or sandy soil (dry humidity is in handcuffs, and drop in the ground to break it down). Just cover it. Then use the same Methods Place the second and third floors.
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.
