1, water control
When the soil is short of water, fig trees are vulnerable to freezing injury. Therefore, before overwintering, the soil should be watered enough to supplement the water consumed by plants in autumn. Adequate water can increase the surface temperature and increase the cold resistance of plants.
Step 2 bury the soil
Burying soil is also a very practical method for wintering. Before freezing in winter, trim plants and cut off some unnecessary branches and leaves to reduce nutrient consumption. Then bury the plant trunk into the soil, which should be uniform, at least 10cm high. It is also necessary to check the cover regularly. After the winter is over and the soil is thawed, remove the soil immediately and then water it in time.
3, white and straw rope
Painting white and tying straw rope are the most popular cold-proof measures, and they are also very common in our lives. Every winter, we can see the trunks in the streets and lanes are painted white, and some trunks are tied with straw ropes. Whitening can reduce the absorption of solar heat energy by fig trees and prevent frost damage; And tying straw rope is even more obvious, that is, putting a dress on the tree can keep warm.
Post-traumatic treatment
Cut off the frozen dead branches on the ground, and the underground adventitious buds will germinate, but the germination time is relatively late. It should be noted that it is not advisable to cut off dead branches and dead branches too early in spring to prevent them from drying up again in case of catching cold.
Extended data:
Field planting
Can be potted or cultivated in barren slopes, fields and courtyards. When farming in barren hillsides, fields, courtyards, etc. Generally, the planting density should be increased appropriately,1× 2m, and the depth of a single planting pit is 50-70 cm.
With a diameter of 40-60 cm, mixed fertilizers containing phosphorus and potassium (such as human and animal manure, green manure, cake fertilizer, chemical compound fertilizer, etc.) are used as base fertilizers, and the suitable planting period should be around Qingming Festival in North China, around Grain Rain in Northeast China, and after autumn defoliation in South China, but the flowering and fruiting period should be avoided.
Plastic trimming
The pruning of figs is relatively simple, and the technical requirements for pruning and shaping are not high. Generally, the pruning method of natural joy and multiple main branches is adopted, but 3-5 main branches are left in the whole plant without side branches, and the main branches are directly planted on the main branches. In the young tree period, we should focus on cultivating the main branches, pay attention to improving the angle of the main branches, promote multiple branches, and achieve the goal of rapid crown expansion.
After entering the first fruit stage, special attention should be paid to cultivating more branches to promote the formation of a certain yield. Pay attention to cultivating backbone branches, renewing large and medium branches, and cutting and shrinking weak branches during the full fruit period. For trees with aging or serious diseases and insect pests, the main branches and branches can be re-cultivated by using budding branches or hidden buds on the base or branches.
Figs began to ripen in mid-July, and gradually reached165438+1October. The picking of figs should generally be carried out in sunny morning or evening. When there is a small hole at the top of the ripe fruit and the peel appears the color of the inherent variety (red and yellow varieties), pick it. Over-ripe fruits are not resistant to storage and transportation after harvesting.
control of insect
Figs are not prone to pests and diseases. During the fruit growing period, it emits a special smell to the surrounding area, which is easy to cause harm to mulberry cattle; Fruits are easily attacked by birds when they are ripe. In addition to artificially catching mulberry cattle and driving away birds, eggs can also be killed manually or by drugs. Scarecrow can also tie plastic ribbons and stick them in the fields to drive away birds.
