Why don't plum blossoms blossom?

There are two main reasons why plum blossoms do not blossom: one is that the new shoots stop growing late, affecting flower bud differentiation. Second, early defoliation reduces the accumulation of nutrients. We must understand the specific reason in order to prescribe the right medicine to the case.

Second, how to blossom year after year?

1. Choose a site with plenty of sunshine and good drainage to plant.

2. Rational fertilization. Nitrogen fertilizer should not be overused. Nitrogen, phosphorus and potassium fertilizer should be applied comprehensively. The effect of applying fertilizer once during the physiological differentiation of flower bud is better than that in other periods.

In the first ten days of March and May, if the growth of the new shoot has not stopped, the tip of the new shoot will be squeezed and wilted by hand to artificially control the growth of the new shoot and force the flower bud differentiation.

4. short-term moderate control of water before flower bud physiological differentiation is beneficial to the accumulation of photosynthesis and flower bud differentiation.

5. It is not easy to grow branches, summer shoots and autumn shoots, so all of them should be cut off in order to reduce the consumption of nutrients.

6. Rational fertilization and irrigation, delaying defoliation and enhancing the function of leaves can promote flower bud differentiation.

Third, how to manage the plum blossoms?

1. Light and temperature

Like warmth and plenty of light. In addition to apricot plum varieties can withstand-25 ℃ low temperature, the general plum blossom can withstand-10 ℃ low temperature and high temperature, even under the condition of 40 ℃. The growth and development is the best in the area with annual average temperature of 16-23 ℃. It is very sensitive to temperature and blossoms when the average temperature reaches-5: 7 ℃ in early spring.

2. Watering and fertilization

During the growing period, we should pay attention to watering, often keep the basin soil moist and partial to the state, neither stagnant water nor too wet and too dry, watering should grasp the principle of dry and wet. Generally overcast, when the temperature is low, less watering, otherwise more watering. It can be watered twice a day in summer, once a day in spring and autumn, and thoroughly dry in winter. Fertilization is also reasonable, apply basic fertilizer before planting, add a small amount of potassium dihydrogen phosphate at the same time, apply potassium dihydrogen phosphate again before flowering, and apply mature cake fertilizer after anthesis to supplement nutrition. Compound fertilizer can also be applied once in June to promote flower bud differentiation. After falling leaves in autumn, apply organic fertilizer once, such as rotten manure and so on.

3. Shaping and pruning

The time of shaping and pruning plum blossom can be carried out within 20 days after blossom. Mainly in the shape of a natural tree, cut off cross branches, erect branches, dry and withered branches, over-dense branches, etc., and cut short lateral branches to promote flowers and leaves to flourish. After the potted plum blossom is put on the pot, it should be re-cut to lay the foundation for the production of bonsai. Plum stakes are usually used as scenes to graft plum blossoms in various postures. Keeping a certain temperature, plum blossoms can be seen in full bloom during the Spring Festival. If you want to blossom on May Day, you need to keep the temperature 0: 5 ℃ and moist environment. Move outside in early April and keep it in a sunny and well-ventilated place to see flowers before and after May Day.

4. Florescence management

Flowering control potted plum blossom is generally for family viewing. Leave the leaves indoors after defoliation in winter, keep the temperature at 0: 5 ℃, then gradually heat to 5: 10 ℃, and receive full light every day, often spray water on the branches, the moisture should be close to the room temperature.
