Analysis on the causes of non-flowering of potted preserved plum and its solution

Wax plum blossom

Lamei let people all over the country know it, pay attention to it and plant it in the spirit of not being afraid of severe cold and frost fighting snow. It has low environmental requirements on soil quality, water source, temperature and so on, so it is very suitable for novice flower breeding. However, in the process of potted preserved plum, we often hear flower friends talk about the problem that there is no blossom when it is full of leaves and branches, and there are mainly the following reasons why it does not bloom.

First, the reason why the dried plum does not blossom

1. The seedlings are cultivated.

The sowing seedlings of Chimonanthus mume need to grow for 3 to 5 years before they can enter the flowering and fruiting stage. Therefore, although potted seedlings are full of water and fertilizer and luxuriant branches, they will not blossom early.

two。 Excessive nitrogen fertilizer

Some wax plums are out of control due to water and fertilizer, especially excessive nitrogen fertilizer, resulting in excessive growth of branches and leaves, affecting flower bud differentiation and leading to non-flowering. Therefore, Lamei should apply nitrogen fertilizer in spring, increase phosphorus and potassium fertilizer in summer and autumn, and apply little or no nitrogen fertilizer to promote flower bud differentiation as soon as possible.

3. Excessive dampness

Lamei likes light, lack of light will affect flower bud differentiation; pot soil is too wet or the place is too shady and wet, it is not conducive to flower bud differentiation. For this reason, we should "buckle water" in late summer and early autumn, and always put it in a place with plenty of sunshine, which can be greatly conducive to the formation and expansion of flower buds.

4. Did not hit the top and pick the heart.

For the plum which has entered the flowering stage, if it is allowed to branch spontaneously during the vegetative growth period in spring and summer, without necessary topping and shoot control, the flower bud differentiation and growth will also be affected because the vegetative growth is out of control. In general, when 3 or 5 pairs of leaves are extracted from the tip, the top 1 and 3 parts should be removed in time to promote the germination of lower lateral buds and the normal differentiation of flower buds. In late summer and early autumn, we should not neglect to hit the top and pick the heart.

Second, the way to make the preserved plum blossom

1. Apply sufficient base fertilizer

Lamei has a large amount of growth and flowering, so it needs to consume more nutrients in order to grow and blossom normally. Therefore, enough base fertilizer should be applied before sprouting, such as rotten cake fertilizer, chicken manure or other organic fertilizer.

two。 Reasonable pruning

Lamei is particularly resistant to pruning, so it is said that "Lamei can not be cut to death". In the dormant period after flowering every year, it should be pruned once, thinning the overdense lateral branches, re-pruning the long branches, and truncating the remaining lateral branches to promote flowering branches.

3. Controlling water and topdressing fertilizer

Lamei blossoms from late November to March of the following year, but flower bud differentiation occurs in July, so watering should be controlled and nitrogen fertilizer should be stopped after the middle of June to inhibit plant vegetative growth, promote its reproductive growth, and apply phosphorus and potassium fertilizer at the same time. And promote flower bud differentiation.

4. Appropriate watering

Chimonanthus is resistant to drought and afraid of waterlogging. Florists have the theory of "immortal Chimonanthus", but there can be no shortage of water in summer, so as not to form withered and whitish patches on the leaves and affect the formation of flower buds. It is appropriate to keep the soil in a semi-humid state. If too much watering, the plant growth is poor, affecting flower bud differentiation. Open-field cultivation should choose sunny and dry places, and pay attention to timely drainage in the rainy season. Flowering must pay attention to a good grasp of the amount of water, more water is easy to drop flowers and buds, less water, irregular blossoms.

5. Pay attention to the wind

Wax plum is afraid of the wind, if you do not pay attention to the wind, the leaves will cause rust spots due to mutual friction. Due to the wind during the flowering period, the petals will not stretch, the bud is not easy to open, or the petals are scorched and wilted by the wind after flowering. To cultivate in the open field, you should choose the leeward and sunny place.

6. Pest prevention

Pests are one of the key points affecting the growth of dried plums, especially in summer, which is the most active season for mosquitoes. as for those pests that are invisible to the naked eye, liquid drugs can be used to prevent them, such as trichlorfon and dichlorvos, and pay attention to dilution ratio.

Deciphering the reason why potted preserved plum does not blossom how to bloom more? Lamei, deciduous shrub, 2-4m high. Stems fascicled, much branched, bark grayish white. Leaves opposite, shortly stipitate, without stipules, leaf blade ovate or rectangular-rounded-lanceolate, 7-15cm long, 3-7cm wide, apex acuminate, entire, base cuneate or rounded, dark green and bright above, rough when old, light green, smooth below, sometimes slightly sparsely hairy on veins. Flowers bloom before the leaves, yellow, full of fragrance. Before that, some flower friends responded that the wax plum they planted grew very luxuriantly, but they did not blossom. What on earth caused it? Next, the editor will give you a brief account. 1. The main reason for the luxuriant growth and non-flowering of potted Chimonanthus mume is that seedlings are cultivated in ①. The sowing seedlings of Chimonanthus mume need to grow for 3 to 5 years before they can enter the flowering and fruiting stage. Therefore, although potted seedlings are full of water and fertilizer and luxuriant branches, they will not blossom early. Too much nitrogen fertilizer in ②. Some wax plums are out of control due to water and fertilizer, especially excessive nitrogen fertilizer, resulting in excessive growth of branches and leaves, affecting flower bud differentiation and leading to non-flowering. Therefore, Lamei should apply nitrogen fertilizer in spring, increase phosphorus and potassium fertilizer in summer and autumn, and apply little or no nitrogen fertilizer to promote flower bud differentiation as soon as possible. ③ is overly damp. Lamei likes light, lack of light will affect flower bud differentiation; pot soil is too wet or the place is too shady and wet, it is not conducive to flower bud differentiation. For this reason, we should "buckle water" in late summer and early autumn, and always put it in a place with plenty of sunshine, which can be greatly conducive to the formation and expansion of flower buds. ④ didn't hit the top and pick the heart. For the plum which has entered the flowering stage, if it is allowed to branch spontaneously during the vegetative growth period in spring and summer, without necessary topping and shoot control, the flower bud differentiation and growth will also be affected because the vegetative growth is out of control. In general, when 3 or 5 pairs of leaves are extracted from the tip, the top 1 and 3 parts should be removed in time to promote the germination of lower lateral buds and the normal differentiation of flower buds. In late summer and early autumn, we should not neglect to hit the top and pick the heart. Second, the way to let the wax plum blossom more, the wax plum blossoms on the branches of the same year, so it should be re-cut after flowering, leaving 3-4 sturdy main branches in each pot, and all the rest of the branches will be cut off, and then pick the heart every time a new branch is pulled out, which can make the branches grow thick and short, and bloom more in the coming year. Lamei likes fertilizer, it is necessary to apply sufficient base fertilizer when changing pots every year, topdressing nitrogen fertilizer when drawing new branches, and increasing phosphorus and potash fertilizer when pregnant buds. The permeable water should be irrigated once the next day after fertilization, which is beneficial to root absorption. Wax plum is early, watering should be dry rather than wet, watering is thoroughly. Too much water will make wax plum fall leaves and affect the formation of flower buds. After flowering, the residual flowers should be removed in time to prevent them from bearing fruit and affect the flowering in the coming year. Conclusion: the above is the analysis of the reasons why potted preserved plum does not blossom. I hope it will be helpful to everyone. The reason and solution of luxuriant growth and non-flowering of potted Chimonanthus praecox; the reason and solution of luxuriant growth and non-flowering of potted Prunus mume (Latin name: Chimonanthus praecox (Linn.) Link ("Flora of China"), English name: Winter Sweet, Chinese alias: Golden plum, wax plum, yellow plum flower. It is a deciduous shrub of the genus Chimonanthus of the family Chimonanthus, often in clusters. Leaves opposite, elliptic-ovate to ovate-lanceolate, flowered in axils of second-year branches, first flowering then leaves, fragrant, 2-4 cm in diam.; tepals orbicular, oblong, Obovate, elliptic or spatulate, glabrous, filaments longer or as long as anthers, anthers incurved, glabrous, style 3 times as long as ovary, base hairy. The receptacle is nearly lignified, the mouth shrinks, and has a subulate lanceolate hairy attachment. The first leaves blossom at the end of winter. The main reasons for the luxuriant growth and non-flowering of potted Prunus mume are as follows: 1. The sowing seedlings of potted Prunus mume have to grow for 3 to 5 years before they can enter the flowering and fruiting stage. Therefore, although potted seedlings are full of water and fertilizer and luxuriant branches, they will not blossom early. 2. Excessive nitrogen fertilizer may lead to excessive growth of branches and leaves due to out of control of water and fertilizer, especially excessive nitrogen fertilizer, which affects flower bud differentiation and leads to non-flowering. Therefore, Lamei should apply nitrogen fertilizer in spring, increase phosphorus and potassium fertilizer in summer and autumn, and apply little or no nitrogen fertilizer to promote flower bud differentiation as soon as possible. 3. Excessive wet Lamei likes light, lack of light will affect flower bud differentiation, and too wet pot soil or too wet place is not conducive to flower bud differentiation. For this reason, we should "buckle water" in late summer and early autumn, and always put it in a place with plenty of sunshine, which can be greatly conducive to the formation and expansion of flower buds. 4. untopped and heart-picked plum which has entered the flowering stage, if it is allowed to branch spontaneously during the vegetative growth period in spring and summer, without necessary topping and shoot control, the flower bud differentiation and growth will also be affected because the vegetative growth is out of control. In general, when 3 or 5 pairs of leaves are extracted from the tip, the top 1 and 3 parts should be removed in time to promote the germination of lower lateral buds and the normal differentiation of flower buds. In late summer and early autumn, we should not neglect to hit the top and pick the heart.
