A course on the latest cultivation techniques of elderberry

Elderberry is a deciduous shrub of honeysuckle family, and its whole plant can be used as medicine. it is a plant with high medicinal value. Elderberry can be seen in many traditional Chinese medicine formulations in our country. There are wild and cultivated areas in many provinces in China, and now the cultivated area of elderberry is getting larger and larger, and many people are beginning to plant it. So how to plant elderberry? The following editor brings you the cultivation techniques of elderberry, let's have a look!

1. planting at the right time

Elderberry is originally a kind of wild plant, so its growth ability is relatively strong, and there is little requirement for soil, as long as the soil is fertile, soft and deep, and free of diseases and insect pests. Generally speaking, the best cultivation time of elderberry is in spring and autumn every year. Before planting, the soil should be prepared, the deep ploughing should be leveled, and then sufficient base fertilizer should be applied. It is necessary to fully mix the base fertilizer with the soil, then return to the soil in time, press the soil firmly and then put it into the seedlings. It should be planted shallowly in spring, otherwise it is a little deeper in autumn. After cultivation, enough fixed root water was poured to promote the rooting and growth of seedlings.

2. Water management

Elderberry has a moderate water demand, which is watered almost once a month when cultivated in spring. But if you encounter rainy days in summer, you can reduce the amount of water, or even not to water it when it is bigger. And after the rain, the excess water in the field should be discharged in time to prevent the elderberry from rotting due to too much water. Elderberry planted in autumn should be fully watered with frozen water, and then released in time in early spring. Planting and watering too much in autumn can easily lead to freezing injury and affect the growth of elderberry. Therefore, when planting elderberry, it is necessary to control water management according to weather changes and planting time.

3. Reasonable topdressing

Elderberry has strong growth ability and has a great demand for nutrition, except for applying sufficient base fertilizer in the field before planting. It is necessary to apply fertilizer at least twice a year before planting, and the first time of topdressing is usually about May-June every year, mainly to improve the growth of elderberry and promote the growth of plant branches. Then the second fertilizer is applied in early winter, and the main fertilizer is rotten farm manure to help elderberry survive the winter. Then urea is applied once in the second year and early spring, and agricultural machinery fertilizer is only needed once a year after the third year.

4. Field management

During the growth period of elderberry, it is necessary to do a good job of weeding and weeding in order to improve the permeability of the field. Generally, deep ploughing should be carried out before the early spring every year, which can not only effectively weed, but also improve soil permeability and promote nutrient absorption. Then a topdressing work should be carried out when the seedlings are about 15 cm and the first time of topdressing, and once every spring and summer after transplanting for 3 years. Finally, the elderberry plants need to be pruned properly to cut off the aging, diseases and insect pests, overgrown and overlapping branches to prevent the light absorption of the plants, but pay attention to keeping the new branches.

The above is a brief introduction of elderberry cultivation technology, elderberry planting is relatively simple, not as tedious as other plants sowing preparation. However, after sowing, it is still necessary to do a good job in water, fertilizer and field management in order to ensure the healthy growth of elderberry and expand its own planting benefits.
