A detailed description of open field, potted, soilless flower cultivation techniques!

China is rich in flower planting resources, and the flower planting industry is a representative new industry in our country, and its planting area and output value are also increasing year by year. Here is a detailed explanation on the technical points of open field, potted and soilless flower cultivation. I hope I can give you a reference.

I. Flower cultivation techniques in open field

Open-field flower cultivation is usually distributed in Yunnan, Guangdong, Shanghai, Beijing, Sichuan, Hebei and other places, and most of the cultivated varieties are in line with the local natural climate and geographical characteristics. Specifically, the key points of flower cultivation techniques in open field mainly include the following aspects:

1. Turn the soil deeply and make beds regularly.

On the one hand, the cultivation of flowers is to facilitate management, on the other hand, it is more conducive to the root growth and development of flowers.

On the other hand, deep soil ploughing can make the soil more permeable, and can play the role of soil sterilization and disinfection and prevent the occurrence of diseases and insect pests.

2. Appropriate thinning of seedlings at seedling stage

Sometimes it is difficult to achieve balance when sowing, and there will be the problem of dense distribution of flower plants. after the discovery, we should thinning the flower seedlings as soon as possible, so that the flower plants can grow stout and healthy.

3. Proper transplanting methods.

In general, open-field flowers can be transplanted either with bare roots or with soil, depending on the variety of flowers. The transplanting time should be in the early morning or evening on a sunny day.

4. do a good job in fertilizer and water management.

In open field planting, attention should be paid to the management of fertilizer and water, usually organic fertilizer should be used as base fertilizer, and then topdressing should be carried out according to the growth needs of different flowers. Watering can choose furrow irrigation or sprinkler irrigation. The water requirements of different flowers are different, which should be known in advance when planting.

2. Cultivation techniques of potted flowers

1. Selection of basin soil

In general, herbaceous flowers, woody flowers and succulent flowers have different needs for soil and cultivated flowerpots. For succulent plants, first of all, the specifications of the selected pots should be small, and the soil should be specially prepared.

2. Pay attention to watering

In the watering area, potted flowers pay more attention than open-field flowers, because of the lack of water regulation of the land itself, it is necessary to artificially regulate water according to flower demand.

3. Pay attention to pruning

Potted flowers pay more attention to ornamental, so more efforts should be made on pruning. Pruning mainly includes heart picking, bud wiping, tip folding, twig bending, bud peeling, pruning and so on.

3. Soilless flower cultivation techniques

The soilless cultivation of flowers mainly refers to the normal growth of flowers not based on soil, but through the preparation of special cultivation substrate and nutrient solution. The main technical points of soilless cultivation of flowers are as follows:

1. Selection of cultivation substrate.

Generally, the substrates of soilless cultivation of flowers are sand, natural gravel, pumice, volcanic rock, vermiculite, perlite, peat, slag, bricks, charcoal, asbestos, sawdust, fern root, bark and so on.

2. Preparation of flower nutrient solution.

In fact, the nutrient solution of soilless cultivation is to provide nutrition by mixing all kinds of nutrient elements needed for flower growth through "watering".
