How about artificial pollination? 5. How about artificial pollination?

How do you artificially pollinate various flowers?

For pollination of small quantities of plants, the stamens can be cut off with tweezers, and the anthers can be rubbed directly against the stigma and the pollen can be scattered on it. When the pollination workload is large, the mature anthers can be removed, the pollen can be shaken and brushed in the glass dish with a brush, and then the pollen is dipped in the pollen and gently smeared on the stigma during pollination, so that the pollen can be stained on the stigma. As the flowers on the inflorescence bloom one after another, the opening time of the florets should be noted during pollination, and pollination should be carried out separately when appropriate.

In order to improve the pollination and seed setting rate, 2 3 consecutive pollination should be carried out within 2 3 days after the stigma is matured, generally 1 time at 9 10 am and 1 3 pm each time, and the next day in the morning or afternoon to repeat the pollination once. The tools used should be clean, and the different mating combinations should be used separately to prevent the pollen from mixing. However, multi-pollination can also be used, that is, several pollens are mixed together and one flower is pollinated at the same time, which can increase the fruit setting rate.

What about tomatoes? When the night temperature of tomato pollen is lower than 10 12 and the daily temperature is lower than 20 22, the pollen viability is not good. A similar situation can occur if the night temperature is 20 22 and the day temperature is higher than 32.

Some varieties have too long a flower column and cannot be pollinated at the time of flowering because the stigma is exposed. Tomato plants have vigorous, well-developed pollen, which can be dispersed from the pollen sac and fall to the stigma by vibrating or shaking the inflorescences, thus achieving the purpose of artificial assisted pollination. The appropriate time to shake the inflorescence or shake the plant is 9 to 10 a.m.

When the flower organ is underdeveloped and the pollen grain is very little developed, the vibrating inflorescence and regulator treatment is better than the use of regulator alone, and the effect of flower and fruit preservation is better. The conditioner should be treated two days after vibrating the inflorescence, otherwise it will interfere with the growth of the pollen tubes. If the plant produces lifeless pollen, it must be treated with a regulator.

When tomato is cultivated in protected areas, manual pollination can vibrate the plants by shaking or vibrating the timber. to promote pollen insemination. It is also possible to move the plants by walking around manually.

It is also possible to spray vibration with a high-pressure sprayer. On the basis of artificially assisted pollination, if it is difficult to preserve flowers and fruits, the inflorescences should be treated with fruit setting regulators. Flower and fruit preservation should focus on normal pollination and fertilization for fruit set.

Artificial pollination refers to the technical measures of using artificial methods to transfer plant pollen to the stigma to improve seed seed rate, or to change plant species in a directional way. It is necessary to selectively select the necessary means of cross-breeding of parental plants.

In terms of fruit tree production, the fruit trees that do not bear fruit trees with self-flowering, monoecious and heterogeneous flowers, and dioecious fruit trees; Artificial pollination is also often required in the absence of pollinating trees or in a harsh climate during the flowering period, which affects normal natural pollination. Flowers are divided into monoecious and dioecious, the same plant can be directly pollinated on the flower, and the heterogeneous plant needs to pollen the flowers of its seedlings of the same variety to pollinate (some blueberries such as O'Neill belong to cross-pollination, and two of the same female parent or similar are needed for cross-pollination).

When pollinating by hand, you can use a clean brush or cotton swab to dip the stamens pollen from one plant and gently apply it to the pistils.

It is also possible to manually attach the male stamen to the female stamen. It is best to pollinate when the flowers are in full bloom on a sunny day, and after pollination, it is best to add thin fertilizer and water to promote seed growth.

Artificial pollination is a technical measure that uses artificial methods to transfer plant pollen to the stigma to improve seed seed preparation rate, or to change plant species in a directional way. In the production of fruit trees, artificial pollination is often required for fruit trees that do not bear fruit fruit fruit with self-flowering, monoecious and dioecious flowers, and dioecious, in the absence of pollinating trees or in the case of harsh climate during the flowering period and affecting normal natural pollination.

Pollination time is the early stage of flowering of the taught variety, before 10 a.m. to 4 p.m., there is secretion of mucus on the stigma of the center of the flower for the best pollination period, as far as a flower is concerned, half an hour after flowering is the best time for pollination, at this time the stigma secretes the most viscous powder, it is best to pollinate for the first time within 4 hours after the flowering peak, and then give the first pollination after the flowers are fully opened.

Artificial pollination considerations

1. Bad weather such as low temperature and dry hot air directly affects the effect of artificial pollination. Pollination is best in the morning on sunny days between 18 and 25. Temperatures below 15 are not ideal for pollination.

2. In case of rain within 2 hours after pollination, re-pollination is required.

3. The pollen left by pollination is not dried and the pollen germination rate is identified as less than 20, and it cannot be used alone in the following year.

4. Please learn more about the method of artificial pollination from the local fruit tree technical department and experienced fruit farmers.

<> artificial pollination is a technical measure that uses artificial methods to transfer plant pollen to the stigma to improve seed seed rate, or to change plant species in a directional way. The following brings you the knowledge of artificial pollination:

Before artificial pollination is carried out, it is necessary to understand the properties of plant flowers, which is like self-pollination. Usually, there are two methods of artificial pollination of self-pollinating plants, the first one is to start the eggplant: the male stamen can be directly on the female stamen; The second:

Use a brush to dip the pollen of the male stamen and apply it to the pistil.

There are several ways in which pollen can be transmitted:1The pollen is dispersed by the flow of the wind, which fertilizes the flower.

Buried group 2by wild bees. Butterflies and flying insects spread pollen.

3.During the flowering season, in a specific location, the farmed bees are used to achieve the purpose of pollination by releasing them in the wild. Today's orchard pollination is predominantly done in this way.

4.Artificial pollination. That is, before the petals of the orange are not burst, when the fruit growers generally call it a bell flower, the flower is plucked, the pollen sac is taken out, placed on a piece of white paper, and placed in the shade, preferably on the kang head to dry until the pollen bursts.

Then put all the pollen into a bottle, then take it to the orchard, and use a pencil with an eraser to dip the pollen into the center of each flower, and dip it once to order many flowers. This method of pollination is more labor-intensive and time-consuming, and is generally not used now. There is also a book of artificial pollination, in which pollen is poured into water and stirred in a certain proportion, and then sprayed on the tree with a sprayer, which is generally not used now.
