Q: Can kiwifruit be cultivated indoors, and how nutritious is it?

Kiwifruit can be cultivated indoors, but indoor cultivation of kiwifruit may cause nutritional unevenness, although it can be grown, but its fruit may not be so sweet, there will be some sourness, because if we cultivate it indoors, it is difficult to provide him with enough light.

First, the maintenance method.

1. Temperature: It can also be seen from its main distribution in the south that it likes higher temperatures, and too low a temperature will lead to a decrease in the yield of the fruit, and the taste is not good. Specifically, it's good to keep it at twenty to thirty degrees.

Fruit trees are not hardy, so care should be taken in winter, especially in the northerly regions.

2. Light: Kiwi trees have high requirements for sunlight. Similarly, the availability of sunlight has a significant impact on the yield and quality of the fruit.

During flowering and fruiting, it is especially important to provide sufficient astigmatism to help them bloom and bear fruit. Only when encountering very strong light should it be slightly shaded.

3. Watering: Kiwifruit likes a humid environment and has high water requirements. When growing fast and flowering, fruiting, it is necessary to keep the substrate moist.

When watering, do not be very dry for a while, and very wet for a while, stable moisture** has a great impact on the quality of the fruit.

4. Fertilization: An appropriate amount of fertilizer will also help the growth of kiwifruit. In general, the number of fertilization applications is three times a year, and the top dressing is twice a year. Before entering the winter, it is necessary to apply winter fertilizer once.

Second, breeding skills.

1. Reproduction: The method of sowing is generally adopted. When choosing a planting site, the main factors to consider are loose soil, proximity to water sources, deep soil, etc., preferably sandy loam.

Then, it's time to select the high-quality seeds. After all the preparations are done, the seeds are planted, taking care that the plant spacing is not too small.

2. Pruning: This step is very important. If it is planted in the same year, that is, a relatively young tree, pruning is mainly to leave three buds at the base, and the method of light pruning is adopted.

If it is an adult tree, it usually leaves four to five buds, and the long branches need to be truncated.

3. Problem diagnosis and treatment.

1. Diseases: There are many types of diseases, some of which will not only threaten stems and leaves, but also harm flowers and fruits, such as "cataplexy", "blight" and so on. Carbendazim can be used, etc., and fertilizer and water management must also be strengthened.

2. Pests: There are many species, such as "leafhopper", "scarab", "shield scale", etc. They can be destroyed with carbofuran, etc.

Indoor cultivation is fine, but it should be moved outside often to bask in the sun.

The late frost in spring has a great impact on kiwifruit, and low temperature damage will affect the germination of spores and the growth and development of new shoots. In spring, the temperature range of new shoots is very narrow, no damage for 4 hours below -1, but 36% of flower buds will be damaged in the following 4 hours, especially near the ground, and the frost damage is more severe. -2 60% of buds are damaged in the following 1 hour.

Kiwi flowers will freeze if they last for 30 minutes below and freeze to death for 2 hours below -2. Therefore, the spring cold has a greater impact on kiwifruit, and kiwifruit orchards should pay attention to the harm of late frost in spring, pay attention to the weather forecast at any time from germination to flowering, and prevent frost damage by releasing smoke and other methods.

Kiwifruit is not tolerant to high temperature and heat, most of the kiwifruit planting areas in China have the threat of high temperature in summer, if the high temperature exceeds 35, it will affect the normal photosynthesis of kiwifruit and reduce the accumulation of nutrients. At the same time, high temperatures are often accompanied by drought, and the leaf edges and tips lose water and become brown, scorched and necrotic and even a large number of leaves are dropped, and the surface of the fruit is sunburned. The sunburn of kiwifruit is a serious sign of severe water shortage in the soil.

In autumn, it is necessary to pay attention to the harm of early frost and late frost, which will lead to abnormal fruits, loss of quality, shrinkage of fruits, and intolerance to storage, and serious fruit deterioration. The growth of kiwifruit fruit from enlargement to maturity takes 210 240 days, and the cultivation area must be able to meet this requirement during the frost-free period.

In winter, kiwifruit must go through a self-determined low temperature stage to remove natural dormancy and ensure normal germination, flowering, and fruiting in the next year. Insufficient low temperature will cause delayed germination and reduced flower size. Kiwis that enter the dormant period need a low temperature of 950 to 1000 hours4 to start vegetative growth again in the short term.

In the southern region, there is a problem of insufficient low temperature time, and the germination rate can be increased by spraying chemicals.

In the selection of kiwifruit, the annual sunshine should be more than 1900 hours, and the number of hail during the growing period should be 1300 to 1400 hours, and the garden should be avoided in shady slopes, narrow valleys and other places with insufficient sunlight. The leaf curtain layer of the plant should not be too thick, and the branches should be evenly distributed, so that the leaves everywhere can get better light.

The temperature is relatively mild, and it is suitable for planting kiwifruit, and if you want to plant kiwifruit, you should also choose land with relatively fertile soil, and kiwifruit can be planted for about 5 years before the people can bear fruit.

The soil is sandy soil, the temperature is kept at about 20 degrees to 25 degrees, and the environment is very suitable for planting kiwifruit.

Grow in an environment with plenty of sunlight. It can bear fruit after 4 to 5 years of planting, and the fruit that grows is very sweet to taste.

1. The planting process: first dig a pit with a diameter and depth of 30 cm, then backfill a little bit of crushed wet soil, and make a small soil bag in the pit. Then talk about the seedling roots riding on the small soil bag, so that the root system is stretched down and stretched around the soil bag, and then fill in the bacon soil.

Gently shake the seedlings to make the roots, the soil tightly combined, the neck of the root and the soil surface are flat or slightly higher than the soil surface, and finally fill the soil and step on the solid, but remember not to use a hoe to smash. In arid areas, it is necessary to cover black mulch, moisturize and warm, which can greatly improve the survival rate of seedlings.

2. Establish a kiwifruit orchard: The environmental requirements of kiwifruit should be considered in the construction of the orchard, and the temperature, water source, sunshine (kiwifruit seedlings like shade and are afraid of direct sunlight, and adult trees like light and shade), soil, wind damage (avoid planting kiwifruit in windy places) and socio-economic conditions (transportation and economic development level).

3. Frame and frame material: The frame has scaffolding, saddle and T-frame. Due to its poor permeability, it is generally not used for the commercial production of kiwifruit.

Every 3 seedlings are erected with a T-type ascending column, which is connected by a No. 10 iron wire in the middle, one every 60 cm. The size of the T-shaped column is 10*10*280 cm, and the length of 80 cm is buried in the soil and compacted. The large scaffolding is made of 8*8*250 cm pillars, 70 cm buried in the soil, and the ground is erected every 6 meters.

The perimeter is reinforced with inclined columns or anchor lines. The surrounding columns are connected with 6*6 cm angle steel beams, and a No. 12 anti-rust galvanized steel wire is pulled every 80 cm on the beams to form a rectangular grid. The vicinity of Chengdu in the Sichuan region is most suitable for the use of large scaffolding, and relatively few cement columns can be used.

4. Seed selection: Kiwifruit is fashionable with red heart and yellow flesh varieties. The red heart varieties have been cultivated in a large area, including Donghong, Red 12, Honghua, Eaton No. 1, Hongyang, and Donghong, Jinhong, Navel Red and so on.

Yellow-fleshed varieties are cultivated in a large area of Jinyan, Jintao, Jinguo, as well as G3G9 and other varieties that were illegally introduced into our country, if you are not afraid of ** high, you can also buy a small amount of seedlings, green meat varieties mainly include Cuixiang, Cuiyu, Jinkui, Haywater, Miliang, Guichang, etc. The factors that need to be considered when selecting seeds are: the seedlings are vigorous, the fruits are delicious, good looking and easy to sell.

The introduction of the growth of fruit seedlings will be introduced (Jinyan, Cuiyu, Honghua and Donghong).

5. Environmental requirements: annual average gas temperature, extremely low gas temperature, maximum gas temperature. Prefers warm, moist, sunny and fertile soil.

Fear of waterlogging, drought, strong winds, and salinity. The requirements for the soil are not strict, and red soil, yellow soil, clay, and sandy soil can be cultivated. However, sandy loam soil with high organic matter content and good air permeability is the most suitable.

Naturally distributed at altitudes of 80-2600 meters, wild kiwifruit grows. The Yangtze River basin in China is the most suitable for kiwifruit planting, and the southern extension of the planting range can reach Heping County in Guangdong, and the northern limit can reach Zibo in Shandong, Luoyang in Henan, and Zhouzhi in Shaanxi in the Yellow River Basin.
