What are the artificial pollination technologies of lychee longan?

Artificial pollination of lychees takes place at the time of the female flowers, of course. Due to the process from pollen collection to pollen spraying, the operation is required to be relatively technical, and it should be fast and efficient, but it is generally difficult to achieve a better effect, and the time for collecting pollen should be sunny day. Pollen is well developed and has a high germination rate on sunny days, and pollen collected on rainy days has a low germination rate.

At the same time, varieties with high pollen germination rate should be selected for pollen collection.

Lychee planting is mainly insect pollination, the pollen mass carried by the hind feet of a honey has about 8 million pollen, and the stigma of a female flower only needs to have a normal development of pollen to arrive, which shows how much the role of sealing in pollination is, lychee pollination time, pollination to the female flower at the beginning of the flower, stigma into an acute angle, the best effect when it is milky white, sunny days after 8 11 a.m. or 4 p.m. Cloudy days can be used all day, and on rainy days, you should shake the branches after the rain stops to dry the flower spikes and spray them.

Collect male pollen and spray it during the blooming period of female flowers. At noon and afternoon on a sunny day, pat on the male flowers with a wet towel, and then put the wet towel stained with pollen into the water, repeat and repeat, obtain light yellow pollen water, and carry out artificial pollination after flowering 5 days, you can also introduce bees for pollination, and the lychee pollinated by bees has a high fruit setting rate, dense fruits, high sweetness, no deformed fruits, and high yield. There is also a reduction in costs and an increase in revenue.

When the male flowers open in the morning on a sunny day, grab a clean wet towel with your hand and put it on the flower spike and pat it or shake it back and forth (if the tree is taller, you can tie the wet towel with a bamboo pole), the towel is stained with pollen and put it into a basin of water to elution the pollen, and then add a kilogram of flowers per 20 kg of water, stir with a bamboo pole to make the pollen fall into the water, filter it with clean gauze, and immediately spray the pollen water on the flower spike of the female flower. Lychee is a female and male fruit tree, except for a very few lychee varieties (shrimp strings, Hainan seedless lychee), the vast majority of varieties have to be pollinated, fertilized to bear fruit. Pollination is the mature pollen of stamens anthers, passed by bees.

Pollination should be done after rain, and it should also be lightly pollinated, and attention should be paid to watering, attention to weeding, attention to pests and diseases, etc., these are all techniques of artificial pollination.

There are many methods, such as dry pollination, pollen washing, film method, pollen collection method, wet towel pollination method, these methods can effectively carry out artificial pollination.

It can be pollinated by insects or bees, or these things can be collected and pollinated manually, which can be selected according to the actual situation, and can improve the yield of lychees.

Artificial pollination begins with pollen collection. There are many ways to collect pollen, so you can choose from it, and when the weather is good, we go to collect it. For example, we can spread a layer of adhesive tape under the fruit tree, and the laying surface of this adhesive tape must be wider, so that it can be conducive to pollen collection.

When we are done, we can choose to shake the tree to let the pollen fall, or we can use some small bamboo poles, or some walking sticks to shake the flowering branches to let the pollen fall. <>

In this way, the pollen falls down, and we can collect the pollen, because we can do the next step when we collect it. Of course, you can also use some wet towels to touch the flowering branches and flowering parts, because it is a towel, it is generally more sticky, and it is easier to use some pollen, so choose to use a wet towel to touch those flowers, which can often absorb some pollen. Of course, with this method, we must take a small basin or bucket, because it sticks to a certain extent, and I have to wash this towel with water to leave the pollen in the water.

The next step is to do artificial pollination, which is nothing more than mixing the pollen that we collect with water and then spraying those places that bloom, so that it can play the role of artificial pollination. When artificial pollination is carried out, there is a premise that it is best to use up these pollen in about half an hour, and it will lose a certain activity after a long time, and being soaked in water for a long time will naturally affect the spread effect of these pollen, and will also affect their quality. <>

Generally, the pollen is collected on the same day, and the pollen is used up on the same day. Of course, there is another point to note, so it can not be a rainy day when pollinating artificially, because it is difficult to have an effect on a rainy day, and the weather is generally sunny, and the air temperature is about 25 degrees.

Pollen can be collected for manual pollination, which is relatively simple and effective in increasing pollination rates.

Spraying pollen directly on the flowers of the lychee will complete the work of artificial pollination, and the healthy growth of the lychee will be completed.

At this time, the best time should be grasped for the fine state, and then when artificial pollination, you must choose a relatively high germination rate, you can choose to pick up the way to shake the branches to collect, you can also choose to use a wet towel to get the way of water, the temperature must be kept between 23 degrees, and it should be fully mixed with water.

Now many people who grow longan will carry out manual pollination, after all, there are not so many bees and so many insects to spread now, and they rely more on manual pollination, and artificial pollination has some precautions, which must be paid attention to, so let's take a look at what should be done. <>

Artificial pollination definitely has this pollen collection, and you can choose to buy it, or you can choose to go for artificial pollen collection when the weather is better. If it is more convenient to buy directly in order to save trouble, but for some professional households, they will choose to collect pollen in good weather, and there are certain precautions when choosing to collect pollen, so it is necessary to collect those pollen that are well developed and have a relatively high germination rate. <>

Generally speaking, the pollen collection method is to choose to shake the way according to the shaking action can not be too much, dense and not too large, it is best to spread a layer of film at the bottom, so that it is easier to collect. There is also a collection method, which is to use a wet towel to dip those pollen, dip a little more, and then wash this towel in water, it is easy to form pollen water.

Artificial pollination generally chooses pollen water, and then uses some sprinklers to spray this pollen water on the female flower blooming tree, so that a simple operation forms artificial pollination. However, when artificial pollination, you also need to pay attention to this temperature, as well as the change of weather, generally choose 8:00 9:

00 This time period is more appropriate, if the weather is cold, you can choose to be in the middle of the afternoon, but it should be noted that do not spread pollen in rainy days, because in rainy days, these pollen are easy to be washed away by rain.

In addition, the pollen water should be sprayed immediately after the mixture, and the whole process should not exceed half an hour, after a long time, those pollen will lose their vitality.

There are two methods for artificial pollination of lychee longan: 1. The most critical technical measure for artificial pollination of lychee is to collect pollen, and there are two most commonly used methods for collecting pollen, one is the film collection method, which is to spread a layer of film under the lychee tree that blooms male flowers, and then shake the lychee tree to scatter the pollen, and then put the collected pollen into water and spray it on the female flower. The pollen collected by this method is of poor quality and the spraying effect is not ideal.

2. The other is the wet towel collection method, which is to place the wet towel on the male flower spike that is in full bloom, shake the flower spike to let the pollen stain the towel, and then put it in the water to wash out the pollen, and then spray it on the female flower. This method has a relatively good effect, but it requires fast, generally from pollen collection to spraying pollen should not exceed 20 minutes, otherwise the pollen activity will be very poor, and the effect is not obvious.

It is very important to pay attention to the collection of pollen, you can buy the finished product or collect it yourself, do not pollinate in rainy days, you need to spray pollen water on top of the female flowers.

By manually exchanging pollen, you can manually pollinate lychee longan, and the method is to have workers hold a special funnel and let the pollen of the two flowers be exchanged.

In our real life, in fact, many times, I believe everyone has a little understanding of lychee and longan, but when we see sunlight on the Internet, which is conducive to the pollination and fertilization of lychee longan, many people will have such questions, is this really the case? For this problem, in my opinion, in fact, I personally think that doing itself is like this, and at the same time, it is also conducive to the growth of lychee and longan, let's learn more about it.

1 itself is so

If we are good at observing life, we will find that the growth of every plant has its habits, that is to say, its growth needs some necessary things and his hobbies, just like each of us has our own interests and hobbies, so for this kind of lychee and longan, in the process of its body, if there is enough sunlight, then it can provide him with pollination and fertilization conditions. That's exactly what it looks like on the scientific grounds.

2 It is conducive to the growth of lychee and longan

In fact, many people like to eat lychee and longan very much in their usual life, we all know that he is a kind of hospitality fruit, and during this period of abundant production, it can really bring us a lot of benefits, because many times, its output is very high, and there are many construction sites, so at this time, ** will be greatly reduced, so many people can consume. At the same time, it is a ray of sunlight, which is also conducive to the normal growth of lychee and longan.

In my life experience, I think most plants can be said to be 80% of plants, and they need sunlight in the process of growth and planting. And sunlight provides them with the necessary conditions for growth. If some plants lack certain light conditions during the growth process, then it will seriously affect its normal growth.

Yes. If the sun is abundant and the temperature is more suitable, the bees will come up to the tree, which is the time to help pollinate the longan.

Yes, when the sun is shining, lychee and longan grow more vigorously, which is more conducive to their insemination.

Of course it is. Because the growing environment of lychee and longan has very high temperature requirements, it can only grow well if it is exposed to sunlight for a long time. So it's very good for lychee and longan.

There are many hybrid species in China, including the hybrid offspring of donkeys and horses as mules, and the products of goats and sheep crosses as mountain sheep. And what I want to talk to you about today is a new variety of longan and lychee hybrid, thatCan longan and lychee be hybridized? What exactly is the fruit of the new hybrid variety?This?

1. Can longan and lychee be hybridized?

Longan and lychee can be hybridized. According to the latest reports, the world's first new hybrid variety of longan lychee, Crispy Honey, was born in Guangzhou. Crispy honey is a new variety crossed by South China Agricultural University, which is of pioneering significance.

2. What is the name of the new variety of longan and lychee hybrid?

The new variety of longan and lychee hybridization is specifically called crispy honey, Kaishou belongs to the genus Longan and Lychee respectively in taxonomy It is understood that crispy honey was originally called Shizi crispy honey, which is a new variety bred by means of cross-breeding between genera.

1.What are the characteristics of crispy honey?

The crisp honey has a yellow-green skin, a large fruit and a thick flesh, and its edible rate is about 70%, and the soluble solid content is about 21%, which has the characteristics of sweet and juicy flavor and aroma. In addition, the crispy honey has the advantages of both stone kip longan and purple lady lychee, the flesh is tender and crisp, completely free of residue, and the sugar content is as high as 20%-24%, which is known as the late-maturing large fruit stone kip.

2.Is crispy honey a longan?

Crispy honey is longan. However, the flesh is very tender, which is similar to that of lychee, and the cracks of the crisp honey peel are very obvious and pimple-like, which is also a characteristic of lychees.

3.What are the trial areas for crispy honey?

At present, Crispy Honey has performed well in test bases such as Chaozhou in Guangdong, Zhanjiang, Conghua in Guangzhou, Lianzhou in Qingyuan, Luzhou in Sichuan and Yongchuan in Chongqing.

It is understood that crispy honey with its late maturity and cold resistance can make the longan production area move north, expand the production area, extend the production period, and in the future Mid-Autumn Festival can also eat Guangdong longan.

In general, longan and lychee can be hybridized, and the new variety of hybridization between the two is called crispy honey, which has begun to be tried in some parts of China. The arrival of crispy honey can prolong the production period of longan.
