Seedlings: purchase seedlings after autumn to before Spring Festival. Time: Yichun planting. Land preparation: travel from north to south, ridging along the road. Deep flip: sprinkle fermented dung. Trench: 60-80 cm deep and 80-100 cm wide. Seedlings: if it is a grafted seedling, carve out the buds of the rootstock. Pollination: artificial pollination. Planting: according to the plant spacing of 0.7 meters, planting to one side of the ridge. Keep alive: cover the wet grass, cover the grass with plastic film, wipe off the rootstock buds after germination, and interplant between rows. Fertilization: timely fertilization and watering.

Kiwifruit is very rich in nutrition, kiwifruit is also loved and welcomed by the majority of friends, so now many people will plant some kiwifruit trees at home. Of course, kiwifruit trees are mainly common in the south, so can macaque trees be planted in the north? What methods do we have when we plant kiwifruit seedlings? Next, the editor will give you answers one by one.

Planting method of kiwifruit seedlings

First, prepare seedlings

1. Purchase seedlings: it is appropriate to buy seedlings after autumn to before the Spring Festival. When purchasing seedlings after the Spring Festival, it is easy to have mixed varieties, and there is a lack of good varieties. Open field and greenhouse are north-south rows, plant spacing of 0.7 meters, row spacing of about 1.8-2 meters, about 500 plants per mu.

2. Transporting seedlings: load the car above zero, and seal the seedlings strictly after getting wet. When Miao arrives at home, unload the car above zero and enter the room, cover it with strict heat preservation and moisturizing, and it is strictly forbidden to be placed in an environment below zero.

3. Seedling storage: if the seedlings are not planted immediately after they are bought back, they can be stored. The method is as follows: in the weather above zero, the seedlings are bundled and buried in a pit with a depth of 60-80 cm, and the covered soil is 30 cm higher than the ground. No irrigation, only sprinkle water, keep below 7 degrees. This method is easy to get hot, and the soil is planted immediately after thawing in spring.

Second, planting time: autumn planting of kiwifruit in open field is easy to freeze to death, and autumn planting in greenhouse is not conducive to dormancy, so spring planting in open field and greenhouse is the best, the time is from January to May, after soil thawing to sprouting, but the later the growth is weaker. In addition, the greenhouse can also plant trees before building the shed.

Third, land preparation and ridging: the open field and the greenhouse are north-south, with a row spacing of 1.8-2 meters, ridging along the line. Large ridges are formed in the cold-proof areas buried in winter, and small ridges are not needed in the cold-proof areas in winter. There are two ways of land preparation before raising the ridge.

Fourth, the whole garden is turned deep: fermented dung is spread on the ground, usually about 5 cubic meters / mu, and more than 10 cubic meters / mu in the new shed. The content of organic matter in the old shed is higher, so there is no need to apply manure. Then turn it about 40 centimeters deep.

Fifth, trench along the road: 60-80 cm deep and 80-100 cm wide. The lower part is filled with about 500 kg of weeds mixed with ripe soil, and the upper part is filled with about 5 cubic meters of organic fertilizer per mu, and mixed with mature soil until filled. If the ripe soil is not enough, it can be dug from between the rows, and the heart soil can be scattered between the rows, and then the water will settle.

Sixth, seedling treatment: if it is a grafted seedling, then carve all the rootstock buds, leaving only the grafting buds, and remove the binding film.

7. Pollination trees: kiwifruit is dioecious, so it is necessary to match pollination trees (that is, one among eight plants) according to 1umber 9, or plant male plants alone and collect pollen from them for artificial pollination.

Eighth, planting method: along the line according to the plant spacing of 0.7 meters, planted to one side of the ridge. The planting method is as follows.

1. Planting to one side of the big ridge in winter: oblique planting to the north, the grafting interface is about 10 centimeters away from the ground. In the future, it will not take root above the grafting interface, and it is convenient to bury the soil to prevent cold. Pour water after planting, continue to bury the mound more than 10 cm above the graft joint when the surface is dry, and remove the mound after germination.

2. In winter, there is no need to bury the soil to the side of the small ridge: oblique to the north, the graft joint is about 25 cm off the ground, pour a lot of water after planting, continue to bury the soil when the surface is dry, and bury it 10 cm above the graft joint, so that the seedlings are on the big ridge, and then the soil is removed to reveal the grafting interface after germination.

9. Moisturizing and activating

1. Cover wet grass 5 cm thick along the road, and cover the grass with plastic film to maintain humidity and increase ground temperature.

2. wipe off the rootstock buds in time after germination, otherwise the grafted buds will not sprout.

3. It is best not to interplant intercropping between rows, but if intercropping must be pulled out in the first ten days of May, otherwise it will be affected by light.

Speed up growth

1. Watering every 7-10 days after planting to keep the surface moist until September. In the meantime, a heavy rain can be watered less, but a light rain is no substitute for watering.

From February to May to August, about 10 kg / mu of 16-8-16 compound fertilizer was applied each time, which was opened in advance and applied with water.

3. Spray No. 24 leaf fertilizer to the bottom of the leaf every 15 days or so.

Can kiwifruit trees be planted in the north?

Kiwifruit can be grown in the north. Temperature is the main factor that limits the distribution, growth and development of kiwifruit. Each species has a suitable temperature range, beyond which the growth is poor or can not survive. The temperature requirements of kiwifruit populations are not very consistent. For example, Actinidia chinensis grows well at an annual average temperature of 4-20 ℃, while delicious kiwifruit is most widely distributed in the range of 13-18 ℃.

What are the suitable growth conditions of kiwifruit

1. Temperature, kiwifruit can grow in areas with an annual average temperature of more than 10 ℃, but the annual average temperature is 15-18.5 ℃, the extreme maximum temperature is 33.3-41.4 ℃, the average maximum temperature in July is 30-34 ℃, the average temperature in January is 4.5-5 ℃, the annual accumulated temperature is 4 500-5 200 ℃, and the frost-free period is 210-290 days.

2. Light, kiwifruit has different demand for light at different ages. Young seedlings like shade and cool, afraid of high temperature and strong sunshine. The sunshine should be more than 1 900 hours.

3. Moisture, the annual precipitation in the ideal kiwifruit producing area is 1 200 to 2 000 mm, and the annual relative humidity is about 80%. There are many mountain fog and high humidity all the year round, which is ideal for the growth of kiwifruit.

4. The altitude can be cultivated from 40 to 2 000 meters above sea level, and it is better to be below 1 000 meters. Above 2000 meters above sea level.

How to prune kiwifruit trees in winter

1. Young trees planted in that year

First leave 3 full buds short at the base of the plant, and then select the sturdiest branches as the trunk to implement the method of light cutting to rapidly expand the crown in the following year.

2. Trees that enter their infancy after growing for one year

When cutting in winter, the mother vine of the main vine should be evenly distributed on the shelf, and the proportion of the fruit vine should be enlarged on the basis of promoting the growth of the main vine, the lateral vine and the fruiting mother vine.

3. Adult trees

In the pruning of adult trees, the fruiting vines should be cut short, generally leaving 5 buds for 4murs, 5 buds for long vines, and 5 buds for long vines, so that they can sprout 4 new shoots; for healthy general vegetative vines, cut off the full length of 1 beat 3 or 1 peel 2 to transform them into fruiting mother vines; for long medium fruit vines and overlapping cross vines, leave 810 buds short, medium fruiting mother vines with 6 buds, and weak ones with 3 buds.

4. Old and weak plants

To carry out the renewal of branches, the specific measures should be carried out according to the condition of the branches, focusing on retaining the fruitful vines that grow at the base of the mother vines, which can be retracted to the strong part. if the growth of the mother vine is too weak, it should be cut off from the place where there are latent buds at the base. let the latent buds sprout out robust shoots.

In the above article, the editor also taught you some ways to grow kiwifruit. Although kiwifruit trees are more common in the south, they can also be planted in the north. If you have land in your home, you can plant some fruit trees appropriately. Because after all, many fruits on the market are treated with pesticides and ripening agents.
