How are apples grown How are apples grown?

1.Flower bud differentiation stage The flower bud differentiation of apples is completed from early June to winter, and the whole process is divided into three stages: physiological differentiation, morphological differentiation and sex cell maturation.

2.Fruit expansion stage The fruit of the apple is a pseudofruit developed from the ovary and receptacle, in which the ovary develops into the center, the receptacle develops into the pulp, and the embryo develops into the seed. The expansion of the fruit is divided into early, middle, ripe, and unripe stages.

The time of fruit expansion is generally 65-87 days for early-maturing varieties, 90-133 days for medium-ripening varieties, and 137-168 days for late-maturing varieties.

3.Flowering period From the appearance of flower buds to the harvest of fruits, apples generally fall flowers and fruits four times. For the first time, at the end of flowering, the peduncle falls off along with the flower, which is often called flower drop.

The second time is about a week after the flowering fall, the ovary is slightly enlarged, which can last for 5-20 days, which is called early fruit drop. The third time in the second fruit drop after 7-14 days, the fruit has reached the mu finger to the Yuan large, the yield has a greater impact, called physiological fruit drop, Yunnan generally occurs in May, the northern phenological period is later than Yunnan, occurs in June, so called "June fruit drop". The fourth time is before the fruit is harvested, the ripe or near-ripe fruit falls, so it is called pre-harvest fruit drop.

Clause. 1. The second flower and fruit drop is mainly caused by insufficient nutrition and poor pollination and fertilization. The third fruit drop, in addition to the competition for nutrients between fruits and the lack of intraembryonic auxin, was caused by the fierce competition for nutrients among the fruits.

Because the osmotic pressure of the leaves is greater than that of the young fruits, the power to compete for nutrients is stronger than that of the young fruits, so in addition to timely topping, cutting shoots and other inhibition of the growth of new shoots, it is also necessary to apply flower fertilizer in time to supplement nutrients.

It was planted from seeds, but now it is mostly grafted.

1. Prepare soil.

If you want to grow apples, the most important thing is to prepare the soil for their growth and development. Apples are suitable for growing in fertile and acidic soils that are loose and porous, with strong drainage and air permeability, so they can be used to grow the soil obtained by mixing humus, garden soil and peat soil evenly.

2. Treat saplings.

Apple planting is generally done by transplanting cultivated seedlings, and apple trees cultivated by the sowing method do not bear fruit, so they are generally not used. However, when using cultivated saplings, it is necessary to choose saplings with relatively intact roots and soil masses that have not been damaged too much, so that saplings can adapt to the new environment more quickly.

3. Planting techniques.

First, dig out a hole about twice as deep as the apple tree sapling with a shovel on the prepared loose and fertile land, and then spread some ripened farm fertilizer or compound fertilizer at the bottom, and then plant the prepared apple sapling.

Apple Growing Tips.

1. Selection of varieties.

If you want to plant a good fruit tree, you need to know the varieties you plant. Many people don't know much about apple varieties, and the most common apple varieties are Yantai apples, red generals and so on.

These are some of the better varieties that growers can choose from. Of course, the selection of varieties should also be based on the geographical environment and climatic environment of their own planting place, and they cannot be blind, because the yield of this kind of apple is good, and the selling price is high.

2. Watering of water.

Apple trees should be watered properly, and the most frequent time to water them is around the time of flowering, and when it is about to enter winter. Watering it before and after flowering is because it is trying to bloom during this period, so give it enough water to make it bloom.

And watering before the winter is because it will enter the dormant period in the winter, and in order to ensure that it can survive during the dormant period, it is necessary to water it in advance. The amount of watering should not be too much or too little, which is not conducive to the growth of the apple tree.

Here's how to grow apples:

1. In the early stage of planting seedlings for the first time, it is necessary to turn over the land scientifically and reasonably and apply some base fertilizer. The season is chosen in March and April. Choose a sunny place;

2. In the process of growing up the sapling, observe and water frequently, and take meticulous care;

3. Around May, the flowers should be thinned, and only one or two stamens should be kept on each branch bud, and the ones that did not bloom should be removed directly;

4. In June, the fruit thinning removes the small fruits that affect the growth, and some of the natural fruits will be eliminated;

5. After planting fertilizer in the soil, you need specific apple fertilizer, not all fertilizer is useful for apple trees;

6. In terms of soil, apples are suitable for sandy loam soils with deep soil layer, good drainage and rich in organic matter. The pH value of the soil should be slightly acidic to neutral. When the soil is poorly aerated, the growth of the root system is stunted.

1. Soil: When planting apples, you need to choose a fertile and deep soil rich in organic matter. 2. Germination:

The apple seeds are planted in moist sandy soil for germination. 3. Planting: Sprinkle apple seeds on the surface of the soil and cover with a layer of plastic film.

4. Maintenance: Move apples to a brightly lit environment to promote their rapid rooting and germination.

1. Soil conditions

Apples are suitable for growing in fertile and rich organic matter-rich soil, when planting apples, you need to apply enough base fertilizer to the soil, you can choose well-rotted organic fertilizer, cake fertilizer or compound fertilizer, and spray potassium permanganate or carbendazim to the soil to control insects and maintain the healthy growth of apples.

2. Germination method

When planting apples, you need to prepare seeds that are full and round and not shriveled, soak them in warm water at 45 degrees for 6-7 hours to absorb enough water, and then bury the apple seeds in moist sandy soil, and control the ambient temperature at about 25 to improve the germination rate of apples.

3. Planting method

When planting apples, you need to spread their seeds evenly on the surface of the soil, water them again to keep the soil moist, and then cover them with a layer of plastic film to keep the temperature in the soil constant, which is conducive to the rapid emergence of apples, and after the apples sprout, the plastic film needs to be uncovered to ventilate them.

4. Maintenance management

Apples are light-loving plants, when cultivating apples, the plants need to be placed in a bright environment, so that they receive all-weather natural light, promote the photosynthesis of apples, and in the apple growing season, it is necessary to apply phosphate and potassium fertilizers 1-2 times a month to promote its rapid flowering and fruiting.

Planting method: 1. Find apples and knives and prepare to start.

2. Cut the apple so that the apple core is easy to pick out.

3. Carefully pick out the apple core with your fingers.

4. Find a small bowl or dish and a sponge.

5. Wet the sponge thoroughly and add a small amount of water to the small dish.

6. Put the kernel on top of the sponge.

7. Put the whole dish on the windowsill and other places where the sun shines, wait for germination, and after germination, it can be transplanted into the soil.

Precautions: 1. Avoid direct sunlight on apple cores.

2. Add water once in the morning and once in the evening to ensure that the sponge remains moist.

Apple seeds can be planted with apple seeds, and apple seedlings grown from seeds are called seedlings. The fruits are relatively small after flowering, just like begonias and begonias, most of them are sour and astringent, so many apple trees are not necessarily planted with seedlings. Can apples be planted directly?

Apple seeds can be planted directly. Generally speaking, apple trees are planted with seedlings. Of course, apple seeds can also be planted directly on apple trees.

In fact, agriculture grows small things. Do apple seeds bear fruit? Apple seeds can produce hail fruits, but planted apple trees bear fruit late.

It generally takes more than 5 years to bear fruit, and the fruit is small. If it is a potted plant, you need to choose a larger pot when planting, then water it reasonably and fertilize it frequently. Only with proper maintenance can you produce apples.

Apple Seed Sowing Time: Apple seeds can germinate and be sown in early spring March. If the growth is good, it can be grafted onto good apple varieties in August and September in summer. How do you grow apples?

Wash the apple seeds and soak them in water for 5-7 days. Change the water once a day. Choose a pot with no holes and put it in the cultivation soil.

Arrange the apple seeds neatly with the tips of the buds pointing downwards. Sprinkle some pebbles and water so that the soil and seeds are completely moist. After that, water is sprayed every 7 days, and the seedlings generally emerge in mid to mid to mid to mid to mid April.
