Is kiwi afraid of the cold, and can kiwi be put outdoors in winter

Severe cold may cause some harm to the kiwifruit tree, and frost may cause tree lesions, affecting the growth and yield of kiwifruit trees, and kiwifruit has different tolerances to extreme temperatures at different stages of development. Kiwifruit had a higher tolerance to low temperature during the dormant period and a lower tolerance to low temperature during the growing period. Delicious kiwifruit varieties can tolerate short-term low temperatures above -15 and long-term sustained low temperatures above -12 after the branches have fully dormant in winter, while they can only tolerate short-term low temperatures and short-term low temperatures after budding and before defoliation.

The tolerance of Chinese kiwifruit varieties to low temperatures is lower than that of delicious kiwifruit. Its tolerance to extreme minimum temperatures is about 1 2 higher than that of delicious kiwifruit varieties, i.e., it can tolerate short-term low temperature hazards above and above -10 during the growing season and dormant season, and above and above -8 in the normal low temperature hazards, respectively.

The harm of sudden large temperature reduction and low temperature beyond the tolerance limit to kiwifruit is manifested in early spring as the buds are frozen, the organs in the buds cannot develop normally, or the developed organs turn brown and die, resulting in the buds can not germinate normally. Or the young shoots and young leaves that germinate change color and die. The frost damage in late autumn is manifested as the tender shoots and leaves that do not have time to fall off normally, dry up, turn brown and die, and hang on the branches and vines without falling off; The fruit that has not been picked has no separation from the fruit stalk, which is difficult to pick, and the fruit cells are not separated after picking, and the fruit cells are not separated, and they are always hard and inedible; Frost damage in the dormant season is manifested as branch cracking, branch water loss, commonly known as "pulling tips or strips", buds are frozen and underdeveloped, or the surface is alive and dead inside, and cannot germinate.

Sometimes, although the degree of temperature reduction does not reach the above indicators, it is accompanied by low humidity and strong winds, commonly known as "dry and cold wind", which will lead to severe water loss and drying, striping, or longitudinal cracking of large branches, or even the death of the whole plant.

Kiwifruit frost damage protection, the method is as follows:

1. Shake off the snow on the kiwifruit tree in time to shorten the freezing time of the tree;

2. Pile up grass and smoke at a certain point in the kiwifruit orchard to promote the rapid melting of ice and snow on the tree;

3. If conditions permit, the canopy or scaffolding can be covered with film to protect the canopy, and weeds or small branches, bamboo branches, etc. can also be put on the canopy or scaffolding to reduce the harm of ice and snow to the branches;

4. Brush the trunk and main branches with 10% fresh lime liquid;

5. After the ice and snow melt, spray the tree with 3-5 Baumé stone sulfur mixture or 600 times the solution of 120 or 500 times of the agricultural anti-agricultural streptomycin;

6. After the ice and snow melt, cut off the branches crushed by the snow in time, and smear the cut with 450-500 times of agricultural streptomycin;

7. Correct the scaffolding and tidy up the branches in time after the ice and snow;

8. Top dressing once before germination, with an appropriate amount of phosphorus and potassium fertilizer as the main fertilizer for available nitrogen fertilizer, and irrigated with water. Generally, the plants put into production are applied with kilograms of urea and kilograms of available phosphorus and potassium fertilizer; Kilograms of urea were applied to the trees that were not put into production, and an appropriate amount of available phosphorus and potassium fertilizer was applied; The first planting of trees depends on the dryness and wetness of the soil, only watering and not fertilizing when dry, and draining and reducing humidity in time when the humidity is high.

Not afraid of the cold. Kiwifruit can be stored for 3-5 months under the kiwifruit, and the shelf-stable varieties can be stored for 8 months! The softening rate of the fruit slows down at 0C.

I think kiwi is still very afraid of cold, kiwi is a tropical fruit, it cannot survive in cold areas, it must have a warm climate.

Are kiwis afraid of the cold? Under normal circumstances, if you can't eat it, it's no problem to put it in the refrigerator, but it's not okay to put it for a long time, because everything has a shelf life and freshness period.

Generally, kiwifruit cannot be placed outdoors in winter.

Kiwifruit likes water and is afraid of waterlogging, temperature and frost, light and shade, and areas with extreme low temperature below minus 15 degrees Celsius and low-lying areas that are prone to waterlogging, no irrigation conditions or pH value above are not suitable for gardening.

Kiwifruit can be stored for two weeks when left in a cool place. Do not take the kiwifruit out and place it in a ventilated place, as the moisture will lose and it will become harder and harder. The correct way is to place it in a box, select a soft edible kiwifruit, and close the box.

Related Notes:

Kiwifruit is a very shelf-stable fruit, which can be stored in the refrigerator at 1-5 C for 3-6 months. When you want to eat it, take it out a few days in advance, and when it becomes soft, you can eat it.

**Fruit kiwifruit medium storability, refrigerated (0 conditions can be stored for 12-16 weeks, at 20, fruit shelf life of about 3-10 days. The fruit is hard to eat, and the flavor is obviously different from "Hayward". The best storage temperature should be () to reduce refrigeration damage and decay.

Kiwifruit is afraid of freezing, kiwifruit likes water and waterlogging, likes temperature and freeze, likes light and is afraid of shade, and areas with extreme low temperature below minus 15 degrees Celsius and low-lying and waterlogged, no irrigation conditions or pH value above are not suitable for gardening.

In addition to containing organic substances such as kiwi nut, proteolytic enzymes, tannin pectins and sugars, as well as trace elements such as calcium, potassium, selenium, zinc, germanium and 17 kinds of amino acids required by the human body, kiwifruit is also rich in vitamin C, grape acid, fructose, citric acid, malic acid and fat.

Hello, kiwi is afraid of cold in winter. For example, the delicious kiwifruit variety can tolerate the short-term low temperature above -15 and the long-term continuous low temperature above -12 after the branches enter full dormancy in winter, while the short-term low temperature and short-term low temperature can only be tolerated after budding and before defoliation.

Kiwifruit antifreeze measures.

1. Strengthen pest control. After frost damage, the wounds of the tree increase and the resistance decreases, which is most likely to aggravate the occurrence of the disease. To strengthen the control of kiwifruit diseases and insect pests dominated by bacterial canker disease, fungicides can be used, such as:

Flurank, Schnaning, thiobacterium, copper hydroxide and other agents are used alternately, sprayed once after the pruning work, and sprayed 2-3 times in the early stage of the disease (mid-February to early to mid-March).

2. If the bark is frozen and cracked, the wound can be bandaged with breathable materials before the spring sprouts to prevent water evaporation and miscellaneous bacterial infection, so as to facilitate wound healing.

3. After the germination of the frost-affected fruit tree, pay attention to the selection and cultivation of root germination and tillering, and for the frozen necrotic plants, you can use the germination tiller extracted at the base to be lignified and use the method of splitting to cultivate a new trunk.

4. Individual fruit trees that are seriously frosted, the main trunk cortex is seriously cracked, and the cortex becomes brown and necrotic, so that nutrients can not be transmitted to the root system, so they should be dug up in time, moved out of the orchard, and burned in an open place.

5. Top dressing once before germination, with an appropriate amount of phosphorus and potassium fertilizer as the main fertilizer for available nitrogen fertilizer, it is recommended to use high nitrogen water-soluble fertilizer + potassium dihydrogen phosphate of sea meal fertilizer; Kilograms of urea and a small amount of available phosphorus and potassium fertilizer were applied to trees that were not put into production. The first planting of the tree depends on the dryness and wetness of the soil, only watering and not fertilizing when dry, and draining and reducing humidity in time when the humidity is high.

Kiwi are afraid of freezing. Kiwifruit likes water and is afraid of waterlogging, temperature and frost, light and shade, and is not suitable for planting in areas where the temperature is below minus 15 degrees, low-lying and waterlogged, and the soil pH value is above the above. If the temperature is too low, it may cause tree lesions, affecting the growth and yield of kiwifruit trees.

Kiwifruit, also known as kiwifruit, fox fruit, etc., originates in Wudu River, Yiling District, Yichang City, Hubei Province, China, the fruit is generally oval, the skin is yellow-brown when unripe, and reddish-brown when ripe.

The surface of the common wild kiwifruit is generally covered with dense hairs, the flesh is bright green or bright yellow, and the seeds are red or black.

Kiwifruit is a dioecious large deciduous spring ridge vine with a flowering period from May to June and fruiting from August to October each year.
