How figs survive the winter, reduce the amount of water / receive proper light / pay attention to anti-freezing

Fig is a highly ornamental plant, in many parts of our country it has been planted, but like many plants, winter is also the most difficult season for figs. So how can figs be safer to winter? There is a detailed introduction below, and the following small series takes you to know about it.

How do figs winter?

Want to know how figs winter, maintenance is very important, and this is the maintenance and spring, summer and autumn three seasons are also different, almost can not make a mistake, otherwise it is easy to cause problems, so we have to look carefully below.

1. conservation site requirement

Fig is a relatively cold-resistant plant, so in winter when breeding it must choose a leeward sunny place, generally if the temperature is lower than 5°C is not suitable for its growth, so we need to remember this.

2. antifreezing treatment

As for how figs overwinter, antifreeze management is very important. First of all, we need to pour plant overwinter water in the soil, which can improve the cold resistance of figs, and then wrap figs with plastic tape, so that they can come out for ventilation when the weather picks up at noon every day.

3. watering management

In winter figs for moisture requirements are not too high, you can refer to figs how to water the article can be watered, here Xiaobian will not introduce too much.

4. sunshine management

In fig how to winter this problem, light is also a more important point, fig is a kind of light-loving plants, so in winter also need to accept light, but because the weather is cold, we can choose to warm up at noon when it moved outdoors to receive light, to dawn can be moved indoors in time.

II. Fig freezing treatment

If you do not follow the above method to maintain and cause figs to be frozen, you must promptly remove the frozen branches, so that the following adventitious buds can germinate, if not treated in time, it will lead to the phenomenon of branches frozen and dead, so we must pay attention to this point.

Winter comes to all kinds of plants "conservation classics"

Winter strikes, temperature drops, great harm to seedlings. In order to ensure the safety of seedlings overwintering, to avoid the death of seedlings caused by frost and physiological drought, the maintenance of various plants at this time is very important.

I. Winter maintenance of trees

Arbor is the backbone tree species of urban greening, its ecological benefits, economic benefits, social benefits and landscape functions can not be replaced by other plants. Therefore, it is very important to strengthen the autumn and winter conservation and management of trees.

First, do a good job of tree pruning: tree pruning is one of the most important measures for tree conservation. Tree pruning in autumn and winter should be based on tree habit, natural tree type and landscape effect, so as to achieve the goal of balancing tree vigor, promoting growth and maintaining beautiful tree shape.

When pruning, the following criteria should be grasped:

1. Reasonable and moderate pruning of dead branches, diseased branches, weak branches, damaged branches, overlapping branches and drooping branches of trees should be carried out to weaken the growth of strong branches, promote the growth of weak branches and reduce diseases and insect pests;

2. Trees that affect pedestrians 'walking, block vehicles' sight, block road signs, traffic signs and skynets should be pruned reasonably and moderately;

3. Trees that have a safety impact on power and communication overhead lines should be pruned reasonably and moderately;

4. Reasonable and moderate pruning should be carried out on trees that affect residents 'lives and production safety due to vigorous growth of trees;

5. Clean up vines that affect the normal growth of trees.

Second, cold: Tianjin winter is cold, dry, windy, some tree species have a certain risk of overwintering, need to strengthen cold management. Cold-proof measures are: spraying anti-transpiration protectants; tree trunk wrapped with straw rope; set up cold-proof wind barriers.

III. Prevention and control of pests and diseases: To eliminate pests overwintering in bark crevices, white trees can be painted, and after mixing the whitening agent evenly, the trunk height can be painted to the ground; to eliminate overwintering pests, the insect source can be eliminated by digging pupae and scraping bark; to spray pesticides on eggs or adults overwintering in trees, timely treatment. Branches, stems and leaves with pests burned or buried deep.

Fourth, clean up litter: weeds and litter are not only the winter places of some diseases and insect pests, but also prone to fire in dry and windy winter. Therefore, the garbage produced by greening should be cleaned up along with the production, and the weeds and leaves should be cleaned up at any time, so as to eliminate both the source of diseases and insect pests and the hidden danger of fire.

II. Shrub winter conservation

December, January, February trees dormant period of the main conservation, management work. To remove the snow on the branches in time to reduce harm. For seedlings afraid of freezing and drying, wind barriers shall be erected in the northwest direction. The wind barriers shall be 2m higher than the cold-proof seedlings, and the wind barrier spacing shall not exceed 25m. In the breeding area, the wind direction should be northwest, and the effect of planting Platycladus orientalis wind barrier is better than artificial wind barrier.

The seedlings undergo a whole pruning before germination. Shape pruning should make the tree high inside and low outside, forming a natural plump round head or semicircular tree shape of shrub pruning should keep the outline clear, the outer edge of branches and leaves close. Shrub bore twigs should be properly cut, strong branches should be appropriately truncated, drooping thin branches and ground tillers should be thoroughly removed.

The bush that grows for many years should renew senescent branch year by year, thin cut bore dense unripe branch, breed new branch. For shrubs with trunk planted for many years, the shearing method of alternately retracting main branches to control crown should be adopted every year to prevent tree vigor from being strong and weak.

Controlling pests in winter often has twice the result with half the effort. Winter is a favorable season for eliminating garden pests. Can dig in the loose soil under the tree to collect the insect pupae, insect cocoons, concentrated burned to death.

III. Winter flower maintenance

Winter is a special time for flower care, and sudden cold waves at this time can make flowers very fragile. Subzero temperatures can also be fatal for plants. However, indoor temperatures are too high, the air is too dry, etc. There are also many reasons for flowers to die. How do winter flowers grow? Remember this six-point package you love to spend a smooth winter

1. Do not water too much, winter water evaporation is small, coupled with flower plants in low temperature growth stagnation, especially the vitality of the root system decline, excessive water, so that the root system breathing is not smooth, easy to cause root disease, or even rotten root death. My pot of cyclamen is due to watering more and there are yellow leaves, rotten stems and other diseases.

2. Less fertilization, flowers to dormancy, all physiological activities basically stopped, the need for fertilizer, water is very small, can maintain life on it. All hibernating flowers do not need fertilization in winter. Fertilization not only causes waste, but also damages the roots of flowers.

3. Winter light intensity is not high, flowers need more light, in order to facilitate photosynthesis to produce organic nutrients, so that the cold resistance of plants to improve; for some winter flowering flowers, but also conducive to lush branches and leaves, flowers bloom bigger, more beautiful.

4. Winter easy to disease are fungal diseases, such as gray mold, root rot, blight, etc., the reason is not low temperature, plant cold resistance decline, so the key to reduce humidity, make plant growth robust, improve cold resistance efforts, and chemical control as a supplement. Pest control is mainly against scale insects and aphids.

5. Because of the dry winter air. Especially in the north, because of the heating, it is more dry, and when the air relative humidity is too low, it will affect the growth of flowers. Requirements of air relative humidity is not less than 80% of the flowers are camellia, azalea, anzu flower, orchid, spider orchid, asparagus, grassleaf sweelflag, saxifraga, etc. The flowers that need air relative humidity to reach 60% include white peony, hibiscus, hanging bell, cyclamen, jasmine, rubber tree, turtle, Milan, Michelia, Pittosporum, cactus, etc. When the humidity is insufficient, it can be solved by spraying water.

6. The indoor temperature should not be too high. Many flowers enter dormancy and semi-dormancy in winter and need rest and rest. Whether in the bedroom or balcony, the temperature should be controlled between 4-8 ° C (flowers that need to sleep), not more than 10 ° C. As soon as the temperature is high, the flowers have physiological activities, even the leaves sprout, wasting the accumulated energy, which is extremely unfavorable for the growth of the coming year. This kind of flower has Milan, gardenia, jasmine, orange, plum blossom, fig, pomegranate, grape, hawthorn, papaya, iron stem begonia, apricot, peach, apple, honeysuckle, spring jasmine, spring orchid, cymbidium and so on.

IV. Winter Conservation of Ground Cover Plants

In winter, most ground cover plants begin to enter dormancy or semi-dormancy, so it is necessary to harvest ground cover plants seeds, clean up dead plant communities and apply winter fertilizer.

East China this month into the middle of winter, before the arrival of cold, for some evergreen, open winter but vulnerable to frost damage to the ground in advance to do a good job of anti-freezing work, generally in the ground sprinkled with sawdust, or in the low withered plants covered with a layer of rice or appropriate watering anti-freezing.

To remove the branches and leaves of perennial root flowers with decomposed organic fertilizer in the root neck soil, promote the next year sprout thick. Deep ploughing and application of thick fertilizer among woody plants with low planting density. Summarize the conservation of the whole year, analyze the experience and lessons, and formulate the improvement, renewal and conservation plan for the second year.

January in East China is the coldest month of the year, and most of the ratoon beds are dormant or semi-dormant. Semi-evergreen species such as chrysanthemum, which have a long green leaf period, cut off the withered aboveground parts at the beginning of January after the seeds are ripe in December.

For land ready for planting, use this time to apply organic fertilizer, such as river mud, on top of tillage in autumn. Woody dwarf shrubs can be fertilized in winter. Encounter January too dry, flowering in spring and early spring germination of the ground is easy to freeze, should choose sunny noon appropriate watering. It can be combined with winter fallow to add soil or drain the badly drained ground cover planting land.

Five Points to Pay Attention to and Four Taboos for Winter Flower Cultivation

Five Points to Pay Attention to and Four Taboos for Winter Flower Cultivation

Because winter temperature is low, humidity is small, the room with heating is extremely dry, the room without heating is very cold, very unfavorable to the growth of flowers and plants. Points to note for winter flower cultivation:

1, pay attention to anti-freezing insulation Now residents 'housing conditions have improved, enclosed balcony is very beneficial to flowerpot wintering, if there is no enclosed balcony, potted flowers at night should enter the room, some particularly cold potted flowers, such as tropical orchids, pineapples, poinsettia, Anthurium, etc. The room temperature at night is preferably not lower than 10℃. 2, pay attention to not too much watering winter water evaporation is small, coupled with flower plants in low temperature growth stagnation, especially the vitality of the root system decline, too much water, so that the root system breathing is easy to cause root disease, even rotten root death. 3, pay attention to not apply more nitrogen fertilizer winter flowers absorption capacity is not strong, apply too much nitrogen fertilizer, will cause the conductivity of the pot soil increased, damage the roots, at the same time, apply more nitrogen fertilizer, make the branches tender cold resistance, disease resistance decreased, is not conducive to winter. 4, pay attention to more sun in winter light intensity is not high, flowers need more light, to facilitate photosynthesis, the production of organic nutrients to improve the resistance of plants, for some winter flowering flowers, but also conducive to lush branches and leaves, flowers bloom bigger, more beautiful. 5, pay attention to disease prevention and pest control in winter are fungal diseases, such as gray mold, root rot, blight, etc., the reason is not in low temperature, high temperature, plant resistance decline, so the key to reduce humidity, make plants grow strong, improve resistance efforts, supplemented by chemical control. Insect pests are mainly against scale insects and aphids. Four taboos for winter flower cultivation: one is that the indoor temperature is too high. Many flower plants enter dormancy and semi-dormancy in winter and need rest and rest. Whether in the bedroom or balcony, the temperature should be controlled between 4-8 ° C (flowers that need to sleep), preferably not more than 10 ° C. As soon as the temperature is high, the flowers will have physiological activities, and even sprout, etc., wasting the accumulated energy, which is extremely unfavorable for the growth of the coming year. This kind of flower plant has: Milan, gardenia, jasmine, orange, plum blossom, fig, pomegranate, grape, hawthorn, papaya, iron stem begonia, apricot, peach, apple, honeysuckle, winter jasmine, spring orchid, cymbidium and so on. Second, avoid fertilizer and water too much. Flowers and plants to dormancy, all physiological activities basically stopped, the need for fertilizer, water is very little, can maintain life on it. All hibernating flowers do not need fertilization in winter. Fertilization not only causes waste, but also damages the roots of flower plants. Three bogeys air dry. The environment in the north is very dry, and the relative humidity of the air is too low to affect the growth of flowers and plants. The flowers and plants that require air relative humidity not less than 80% are: camellia, azalea, anzu flower, orchid, spider orchid, asparagus, grassleaf sweelflag, saxifraga, etc.; the flowers and plants that require air relative humidity to reach 60% are: white peony, hibiscus, golden bell, cyclamen, jasmine, rubber tree, turtle, Milan, Michelia, Pittospora, cacti, etc. When humidity is insufficient, water spraying can be used to solve the problem. Four taboos do not see the sun. Keep flowers and plants in good light or in the sun for a period of time each day. It is best to ensure that there are at least 3 hours of light per day, so that flowers can thrive in the coming year. Even if winter leaves, no leaves of woody flowers, but also to see the sun, long-term in the dark place is absolutely not desirable.
