Kiwi fruit tree inverted spring cold prevention technology

  The newly planted "Spring on the 16th" kiwifruit saplings can be safely wintered in the Tai'an area without freezing damage. Because the germination of the variety is earlier, the germination of the buds in the spring is delicate and fragile, and it is easily attacked by the cold in the spring. The browning of the damaged part is hindered, which seriously causes the fruit quality to decrease and the yield is reduced; The solution is as follows:

First, the construction of protective forest belts planting arborescent fast-growing tree species and shrubs in the orchard around the orchard, holly, holly, etc., can effectively enhance the cold and prevent wind damage to the branches, leaves, flowers and fruits of the fruit trees during the growing season, Play a role in protecting the orchard.

Second, the whole garden irrigation Before the kiwi bud sprouting, the whole garden is generally flooded, not only to mediate the microclimate, but also to delay the phenology, flowering and other phenological periods, can avoid the cold and cold attacks.

Third, the tree spray protection agent In the germination of the kiwi tree bud to the germination stage, the plant freeze protection agent recommended by the plant protection department can be selected. Such as: using Tianda 2116 fruit tree special type 100 times sprayed vines better. You can also use about 50 times of quicklime emulsion to spray, every 6 days or so, to effectively reduce the damage.

4. In time, smoke and avoid cold. When the cold is coming, listen to the weather forecast at any time. Before the cold current comes, you can pile up fallen leaves, weeds and other firewood in the upwind of the orchard, and ignite in time to let the thick smoke fill the ground air in the orchard. Reducing the upward heat of the ground heat can increase the mantle temperature until the sun rises and the temperature ends normally.
