Recently, many flower lovers are asking Xiao Qi a question, that is, why does he only bloom and not bear fruit in the lemon I raised? Even if the fruit bears fruit, the fruit will fall in large quantities, what is the reason for this? In fact, the lemon only flowers and does not bear fruit, it must be these two points are not done well, if you reasonably improve it, the next time it blooms, it will definitely be able to hang full of fruit.
1. Pollination
Our lemon it can be self-pollinating, he can have both male flowers and female flowers on a plant, his male flowers are used to pollinate the female flowers, the female flowers with a drum bag in the middle, this is to put the pollen of the male flower directly on this bulge to complete pollination, and her female flower with the bulge at the same time there are some flower buds around, there are pollen on the flower buds, this pollen can also pollinate the lemon. If we are a lemon cultivated indoors, there is no wind and no insects, and after the flower comes, you directly wait for it to fall off on its own, then he will not bear fruit at all, because he has not completed the pollination work, and its fruit will not take shape at all, so the lemon we raise will only flower and not bear fruit.
At this time, some flower friends will say, my lemon blossoms, there are no male flowers when flowering, so how should I pollinate? As long as it blooms all female flowers, you can go pollination, with the pollen of its female flowers directly to the stigma, it is also possible to complete pollination, but the probability of female pollination success will be smaller, generally around 50%, we pollinate to choose the right time, we go to observe pollen, generally its pollen is yellow color, this time pollination success rate is very high, if the pollen completely becomes white, you go to pollination is basically unsuccessful, it is recommended that everyone in his morning around eight o'clock flowers bloom, Pollinate him when the pollen is yellow, so that the success rate is the highest.
2, supplement nutrients
Lemon flowering fruit consumption of nutrients are very much, a lot of flower friends raised lemon leaves yellow, the whole plant has yellow leaves, and is flowering, in this case if you go to pollinate it in time, he blossoms the fruit will also yellow themselves fall off, and no pollination is exactly the same, why is this? Because this is the lack of nutrients in its entire plant, many flower friends will use a lot of potassium dihydrogen phosphate for him in order to make the lemon blossom, and the use of potassium dihydrogen phosphate can allow him to differentiate the flower buds, and it divides the flower buds to consume nutrients in the branches and leaves, and eventually the flowers will grow out to open.
But after it blooms, pollination succeeds, he wants to consume nutrients to gradually expand the fruit, there is no fruit fall, so lemon you use potassium dihydrogen phosphate to promote flowers can make it grow rapidly, but after it grows out of the buds we have to ensure the sufficiency of other nutrients, to ensure the development of its root system, so we raise lemons to promote flowers choose to use potassium dihydrogen phosphate, potassium dihydrogen phosphate you can give him to use twice, twice a month potassium dihydrogen phosphate, once nitrogen phosphorus potassium balanced multi-element fertilizer, In this way, its root system will be more developed, and it can sufficiently absorb nutrients to supply him to flower, and after the flowers bloom, they will complete pollination, and its fruit will be able to prevent it from falling.
And in the process of planting lemons in our pots, many people will choose to use garden soil, and the nutrients in the garden soil are seriously missing, so it is even more necessary to supplement fertilizer. In addition, we supplement fertilizer at the same time, to ensure that he is supplemented once a month with ferrous sulfate, because she is a typical acid-loving plant, acid-loving flowers have a relatively large demand for iron, regular supplements to prevent soil alkalinity, so that its root system is more developed, if the soil alkaline iron element is missing, its leaves will be yellow, and its root system will be very weak, it is difficult to sit fruit after flowering.
Lemon is more suitable for potted plants, more suitable for indoor raising of a fruit tree, if you raise lemons at home only flowering and not bearing fruit, it is these two points are not done well, what we need to do is to first ensure the ventilation of the environment, ventilation is not easy to attract insects, its growth will be better, followed by to ensure that the water and fertilizer are sufficient, in general, the pot soil is dry to about half of the timely watering for him, fertilizer in the spring to add it twice potassium dihydrogen phosphate, a multi-element fertilizer, so has been used, After the fruit is seated, we can properly thin the fruit and keep one of each branch of the fruit.
Flowering on the fine branches as far as possible do not go pollination, only keep the thick branches, so that the probability of its fruit sitting will be very large, the later stage will not appear to fall fruit, and then regularly water it ferrous sulfate, to ensure that the soil is acidic, to ensure that the iron element is not missing, you raise at home lemons can bloom every year, as long as pollination can hang full of fruit.
