Does rain and snow affect the survival of newly grafted kiwifruit?

The rain and snow weather in the early stage of newly grafted kiwifruit has an influence on its survival. Because the newly grafted kiwifruit seedlings are afraid of low temperature, in rainy and snowy weather, we can build a greenhouse and cover the kiwifruit seedlings with plastic film, which can keep the kiwifruit seedlings warm and promote their growth. This can protect the newly grafted kiwifruit seedlings. Therefore, the newly grafted kiwifruit will have an impact on its survival if it rains and snows in advance.

Kiwi, also known as kiwi fruit, is generally oval, with a green-brown appearance in the early stage and a reddish-brown appearance after maturity. The epidermis is covered with dense fluff, which is inedible. The flesh is bright green and there is a row of black or red seeds inside. Because macaques like to eat, they are named kiwifruit; It is also said that it is named because the skin is covered with hair and looks like a macaque. It is a fresh and tender fruit with rich nutrition and delicious taste.

Kiwifruit is soft, sweet and sour. This taste is described as a mixture of strawberries, bananas and pineapples. In addition to organic substances such as actinidine, proteolytic enzyme, tannin pectin and sugar, trace elements such as calcium, potassium, selenium, zinc and germanium, and 17 amino acids needed by human body, kiwifruit is also rich in vitamin C, grape acid, fructose, citric acid, malic acid and fat.

growing environment

temperature

Temperature is the main factor limiting the distribution, growth and development of kiwifruit. Most kiwifruit varieties require warm and humid climate, that is, subtropical or temperate humid and semi-humid climate, which is mainly distributed in the vast area of north latitude 18 ~ 34 degrees. The annual average temperature is about11.3 ~16.9℃, the extreme maximum temperature is 42.6℃, and the extreme minimum temperature is about -220℃.

Kiwi is a fruit tree that needs water and is afraid of waterlogging. It is a fruit tree with weak physiological drought tolerance and weak moisture tolerance. Therefore, the requirements for soil moisture and air humidity are strict, which determines that kiwifruit is most suitable for planting in areas with abundant rainfall, uniform distribution, high air humidity and moist but not waterlogging.

The drought resistance of monkey peach is worse than that of ordinary fruit trees. Kiwi has large and dense leaf shape, large transpiration and large water demand.

illuminate

Kiwifruit likes semi-cloudy environment, likes sunshine but is sensitive to strong light, and belongs to a fruit tree variety with moderate preference for light. Sunshine time requirement 1300-2600 hours, prefer diffuse light and avoid direct light. The results show that the plant needs some light, and the suitable natural light intensity is 42% ~ 45%.

land

Slightly acidic sandy soil with deep fertility, good air permeability, groundwater level below 1 m, high organic matter content and PH value of 5.5-6.5 is suitable, and strong acid or strong alkali soil can be planted only after it is improved.

altitude

Kiwifruit can generally be planted at 800- 1800 meters, but the altitude of 1000- 1600 meters is more suitable. [6]

Other conditions

Kiwifruit is quite weak in wind resistance and vulnerable to wind damage. The main reason is that its leaves are large and inelastic. Strong winds cause shoots to break, leaves to break, and fruits to be bruised or shaken, thus reducing yield and commodity performance. Therefore, the mountain garden construction should try to avoid choosing the windward mouth, ridge and windy area at the top of the mountain, and should choose the leeward slope with the direction of early sunny slope and late sunny slope.

Grafting is one of the artificial vegetative propagation methods of plants. That is, the branches or buds of one plant are grafted to the stems or roots of another plant, so that the two parts connected together grow into a complete plant. Grafting methods are divided into branch grafting and bud grafting. When grafting, the scion should be closely combined with the cambium of rootstock to ensure the survival of the scion. Grafted branches or buds are called scions, and grafted plants are called rootstocks or scions. Generally, seedlings with 2 ~ 4 buds are selected as scions, which become the upper part or top of the plant after grafting, and rootstocks become the roots of the plant after grafting.

The rain and snow weather in the early stage of newly grafted kiwifruit has an influence on its survival. Because the newly grafted kiwifruit seedlings are afraid of low temperature, in rainy and snowy weather, we can build a greenhouse and cover the kiwifruit seedlings with plastic film, which can keep the kiwifruit seedlings warm and promote their growth.
