Do I need to be hand pollinated to grow peaches? How is peach blossom pollination?

Different varieties of peach trees need to be pollinated. For example, some peach trees need to be pollinated by hand, and some do not. I believe that you must have accumulated a lot of life experience in your daily life, because we need these common sense to help us solve some problems in our daily life.

Once we have this knowledge, we will be able to solve problems easily and easily without making mistakes. Therefore, I think that it is helpful for me to accumulate more common sense in life. Recently, some netizens asked:

Does a peach tree need to be pollinated by hand? After inquiring about the relevant information, I will tell you the answer to this question. <>

1) Different varieties of peach trees need to be pollinated.

I believe that you must know that technology is very developed nowadays, and people usually use some genetic technology to improve some species so that they can be productive. Of course, peach trees are also divided into many varieties, so for the aspect of artificial pollination, some peach trees have different needs. For example, it is understood that it is a peach tree that matures early in early June, so it does not need to be pollinated by hand; One bears fruit after late June, when it needs to be pollinated by hand.

So this is not the same for them. <>

2) The difference is that the results of different time periods also have an impact on their pollination needs.

If we know a little bit about biology, we will know that some fruit trees need to be pollinated before they can bear fruit. Some are pollinated naturally, such as by wind or by some animals, while others are pollinated by hand. In fact, this is also related to the natural environment, for example, the wind direction in some seasons and the reasons for some animals' rest, the lack of natural pollination conditions, so that artificial pollination is required.

Yes, peaches also need to be manually pollinated when planting, as long as the pollination is done well, peaches can have a high yield, and we should also pay attention not to choose rainy days when pollinating.

Look at what kind of peaches they are, different varieties are planted in different ways, and when you go to the orchard to buy fruit trees, those people will tell you how to plant them.

Growing peaches requires artificial pollination, which can not only improve fruit set, but also promote fruit development.

It is best to pollen when the flowers are white and tender, and the pollination time should be in the morning, and the morning is the best time. Because the flowers that did not bloom bloomed overnight, they all bloomed in the morning.

At that time, the best time to spot pollen, if it is past noon and the temperature is high, it may turn red in the morning and noon. It's best in the morning, the best time, so be optimistic about the weather, grasp the time, and be sure to give it within three days.

Peach blossom is the axillary bud of the annual full peach, the flower bud is differentiated in July, and the habit of flowering in the spring of the second year, so it is necessary to pay attention to pruning, the young peach is mainly to grow the peach crown, prune in time after flowering, and only retain two or three buds at the base of the flowering branches, and the rest are cut off.

In summer, the branches that are overgrown are topped to promote the formation of flower buds. For plants that do not grow well, we should avoid pruning too much, should suppress the strong and help the weak, and pay attention to the uniform distribution of branches, resulting in a beautiful plant shape.

Cultivation Techniques:

Peach blossom transplanting and planting are mostly carried out in early spring or autumn and winter after the leaves fall, planted in a drained and sunny place, and the base fertilizer (human manure, compost, cake fertilizer, bone meal, etc.) is applied in the planting hole to promote the differentiation of flower buds.

Bare root transplantation can be used for young seedlings; Large seedlings and trees, especially the more expensive varieties, are best transplanted with soil masses, or at least the roots are soaked in mud and then transplanted to ensure survival.

The shaping is mainly natural and open-hearted, and the pruning can be slightly heavier than that of the plum, that is, thinning and stubbing, and pruning the slender branches, cross branches and diseased branches in the canopy, which are more than before flowering, and can be postponed until after flowering.

Generally, basal fertilizer is applied once a year in winter, and top dressing is applied once before flowering and around June to promote flowering and flower bud formation. In addition, proper cultivation and weeding should be carried out at ordinary times.

Pollination can be done using insects or by hand. Artificial pollination is the first to pick flowers, in the first 2 3 days of scheduled pollination, collect the flowers of the big bud stage, bring them back to the room, rub them with their hands, concentrate the anthers in the white paper, remove the petals, filaments, spread them thinly, and place them in a ventilated and dry room of 20 25, and pollinate them after 1 2 days.

Peach blossom period. The flowering time of peach trees can generally last for a week, and the stigma within 1 2 ft after flowering has the most secretions, which is also the best time for pollination.

Peach tree pollination often adopts the method of manual point teaching, and the flowers that bloom soon on the same day, the stigma is tender and green, and there is mucus secretion. The early and full flowering flowers have a high seed setting rate and large fruits, so the pollination effect of the first flowering is the best. Therefore, it is advisable to repeat the teaching.

Peach pollination varieties are generally dominated by Okubo, which has early flowering, a large amount of pollen, strong affinity, and the best artificial pollination effect. Preparation of pollen. 2-3 days before pollination is the best time to make pollen.

The specific method is to choose a thriving nectaria oil tree, pick up the flower buds containing aphids, wipe the anthers from the stamens in time, and then remove impurities such as petals with a fine sieve. The anthers are thinly placed on newspaper and left to dry indoors, which need to be dry indoors, ventilated, dust-free, and the temperature is controlled at 20 to 25 ° C. When the temperature is too low, the anthers are not easy to crack and the powder slows down; The temperature is too high, which affects the viability of the pollen.

Be careful not to expose the anthers to sunlight. After 24 hours, the dried anthers are finely crushed to remove impurities and golden pollen is obtained. Place the pollen in a brown glass bottle and store it in the refrigerator below 0 °C for later use.

Bad weather such as low temperatures and hot and dry air directly affects the effectiveness of artificial pollination of peach trees. On a sunny day between 18 and 25°C, pollination is best done in the morning. When the temperature is below 15, the pollination effect is unsatisfactory.

If it rains within 2 hours of pollination, re-pollination is required. In the case of artificial pollination, fruit protectors used to protect flowers can be used in combination. The remaining pollination of the pollen was not dried, and the pollen germination rate was less than 20.

It can't be used alone next year.

Pests and diseases will directly affect the quality of pollen of fruit trees, some do not bloom, and even cause flower and fruit drop, which has to attract the attention of fruit farmers and friends. In terms of pests and diseases, prevention is the main thing, supplemented by pesticide spraying. When it comes to preventing pests and diseases, the most common means is to clear the garden in winter and spring.

Through garden cleaning, the pathogens in the orchard and the base number of pests in the orchard can be effectively reduced. When the peach tree is in bloom, the most feared thing is even cloudy days. Continuous cloudy days will directly affect the normal pollination of fruit trees, and also affect the photosynthesis of fruit trees.

Therefore, it is important to always pay attention to weather changes before and after the peach tree blooms. If it is cloudy, do a good job of manual pollination and bee release in advance.

Yes, because these peaches have different flowering times, and only artificial pollination can affect the fruit setting rate, and can also improve the yield, and will not cause pollination due to the influence of the climate.

Yes, because there is a shortage of pollinated products, and generally growing fruits and vegetables need to be pollinated by hand, so as to ensure the quality of food.

Manual pollination is required because this ensures the yield of peaches and can also achieve the pollination effect.

It is also needed, because some peaches cannot be pollinated by themselves, so the seeds need to be pollinated manually to produce peaches.

Pro, peach blossoms are generally cross-pollinated, but in some special cases, peach blossoms can be self-pollinated.

Self-pollination is the flowering that has both stamens and pistils, and heterofloration is a male and female plant. Self-pollination refers to the phenomenon in which pollen from one flower falls on the stigma of the pistil of the flower (as distinguished from cross-pollination). A few plants in nature are self-pollinating, such as barley, wheat, soybeans, etc.

Cross-pollination refers to the pollination between different plants, different flowers, and different clones. Some plant stamens and pistils do not grow in the same flower, or even on the same plant, these flowers cannot pollinate themselves, and their pistils must get the pollen of another male flower, which is called cross-pollination. The flowers of self-pollinating plants must be hermaphroditic, and the female and stamens are very close to each other, and the pollen is easy to fall on the stigma of the flower; The female and stamens should mature at the same time.

However, plants with hermaphroditic flowers are not necessarily self-pollinating. Angiosperms are mostly cross-pollinated, and a few are self-pollinated.

First of all, it is necessary to see whether the flower is a complete flower, that is, there are pistils and stamens, and the pistil and stamens must also mature at the same time, that is, the pistils can also be pollinated when the pollen falls off, if the two mature at the same time and the petals still wrap them when they bloom, it must be self-pollination, because other pollen can not be touched, if a flower only has pistils or only stamens, like watermelon cucumber or the like, it can only be cross-pollination, and the remaining flowers have stamens, and mature at the same time, but completely open, Even the stamens we can see, and it is difficult to judge whether it is self-pollination or cross-pollination. In fact, there are very, very few plants that are self-pollinating, most plants are cross-pollinated, and most plants are cross-pollinated, and the fruit grows better than self-pollination - but explaining this directly in terms of hybrid advantage is too simplistic and really wrong to the point. Because genetic diversity does help plants, the traits that promote genetic diversity are preserved, and there are various means to prevent self-pollination, for example, there are actually many plants that are self-infertile - when self-fertilization does not produce fruit or produces smaller fruits, so it is not the advantage of hybridization that makes the false fruit develop better, but to prevent self-pollination and prevent the fruit from growing.

Questions. Do you use a brush!

The above is all my reply, I hope to help your relatives, I wish you a happy life.

Do you want to be pollinated by hand?

It can be pollinated by hand with a brush.

When the peach blossoms bloom, you can use a brush to sweep the pollen of the male flower onto the bud of the female flower, so that the pollination is completed.

If it is planted in batches and in a large area, it is also possible to collect the pollen of the male flowers at one time and then spray them with spray, which is more efficient.

Collect pollen. From late April to early May, the male flower spikes of the male type can be elongated by 8-12 cm, and turn from green to yellow, when the stamens turn apricot yellow or when the stamens at the base of the flower spike begin to have a small amount of loose pollen, the flower spikes can be picked and placed in a ventilated and dry room, scattered on clean kraft paper or newspaper, and all the pollen can be scattered after 1-2 days.

After the pollen is loosened, use a new brush or pen to collect the pollen together, put it in a glass test tube or an empty bottle containing penicillin, and fill it to 1 2 places, and then use absorbent cotton to plug the bottle mouth to make it breathable. If it is used within two days, it can be placed in a cool room. 3-6 days of use, can be refrigerated in the refrigerator, the temperature is 3-5 degrees Celsius.

Do not mix gypsum powder, talcum powder, starch and the like into pollen, because walnut pollen is most afraid of drying, and after these things are mixed, the pollen will quickly lose water and lose its vitality, making pollination fail.

Methods of pollination. Sprinkle powder with bamboo poles manually.

First of all, the pollen is packed into a cloth bag sewn with 3-4 layers of yarn and 10-12 cm wide, the pollen can not be too full, put it into 1 3 to 1 2 places of the cloth bag, seal the mouth of the bag, and then tie the cloth bag with pollen to the top of a 2-3 meter long bamboo (wood) pole. When pollinating, a person can hold a bamboo pole between the rows of the walnut tree and shake it 1-2 times above the walnut trees on both sides. Then go to the next row of walnut trees and shake it.

Pollinate with a duster.

Use a medical throat duster, put the pollen into the glass bottle of the duster, put it in 1 2 places, spray it away from the canopy, spray it on the middle and upper part of the tree, and then spray it on the opposite side.

Pollination time. Pollination time is important for walnuts, and pollination is generally done by 8 a.m. Because the stigma secretes the most mucus in the morning, the air humidity is high, and it is the best time for the stigma to receive pollen.

If you want to bear more fruits, you can pollinate artificially, the time should be selected in the windless, sunny morning for pollination, pollinated peach blossoms are best carried out after half of the opening, the weather is sunny plus there is no wind obstruction, pollen is easy to stain the stamens, if the flowering period encounters rainy weather, after the rain there is no rain on the stamens and then pollination, pollination will begin three hours after fertilization, so after pollination of peach blossoms to pay close attention to future weather changes, once there is unfavorable weather for pollination, to supplement pollination in time.
