When is the best season to plant preserved plums? In which month is the survival rate of Lamei seedlings high? Wax plum planting: seeds are sown from February to March.
Sowing seeds
It is generally harvested when the dried plum fruit turns yellow from July to August, and the seeds are dried and stored for sowing in February-March of the following spring. The thickness of the covered soil is about 4cm. If the seeds are soaked in warm water before sowing, it can promote germination. After the seedlings were unearthed in April, we should pay attention to prevent the harm of Bombyx mori and strengthen the management without protecting the shade. The seedlings grow slowly, and the height is only 10ml / 15cm. The rootstocks of Prunus mume can be cultured in large quantities by sowing method, but it takes a long time to cultivate.
Administration and Management
1. Watering
Lamei usually watered to maintain the soil semi-moisture state is better, pay attention to drainage in the rainy season to prevent soil water. Replenish water in time in the dry season, and during flowering, the soil should be kept moderately dry and should not be watered too much. Potted Chimonanthus praecox is planted in spring and autumn, the pot soil is not dry or irrigated; in summer, the water is watered once every morning and evening, and the amount of water is controlled according to the dry and wet condition of the basin soil.
two。 Fertilizer application
In potted Chimonanthus praecox, fertilizer and water will no longer be applied at the early stage of potting, leaf fertilizer should be applied in spring, fully mature organic fertilizer should be applied once a year after flower fade, and rotten cake fertilizer and water should be applied every 10-15 days from spring new leaf germination to June growth season, and during the flower bud differentiation period from July to August, the mixture of mature organic fertilizer and phosphorus and potassium fertilizer should be applied. Apply organic fertilizer again after autumn. After each fertilization should be timely watering, loosen the soil, in order to keep the soil loose, do not apply fertilizer during flowering.
3. Pruning before flowering
Before the flower buds expand after falling leaves, leave one more pair of leaf buds on the flower buds for the long branches, cut off the upper part without flower buds, and remove withered branches, disease and insect branches, over-weak branches and dense, overgrown non-flowering branches and roots that are not used for renewal. Be careful not to touch the flower buds.
4. Post-anthesis pruning
Lamei removes the old branches, withered branches, overdense branches and long branches, and retracts the weak main branches or branches. For the main branches that are too high, too long and too strong, they can retract at the larger oblique branches, take the lead with weak branches, and control the height, length and potential of branches. Cut short annual branches, keep 30-40 cm for extended main branches, 10-20 cm for other strong branches, and leave a pair of buds or thinning for weak branches. After the flowers fade, pick the residual flowers in time.
Growth habits and planting season of Prunus mume
1) growth habits: wax plum likes sunlight, can tolerate shade, cold, drought, waterlogging and wind, and is more resistant to cold, strong tree growth, pruning and easy shaping, so it is suitable for planting in a wide range of areas.
2) the planting season of Chinese plum: generally, it is planted from March to April, because March to April is spring, the temperature is warmer, and there are many seedlings suitable for planting, among which Prunus mume is a kind of.
3) under the condition of ensuring the survival rate, the general Lamei seedlings are suitable for planting or transplanting from March to June. Due to the dry and hot weather in March-June, adapted to the growth of seedlings, preserved plum was planted in March-June, and its survival rate was more than 60%.
