Various flower planting methods Common flower planting

1, Rose:

Disinfect the soil before planting, mainly with steam. When there are no conditions, it can be fumigated with chloropicrin. After fumigation with chloropicrin, deep ploughing should be carried out for many times to avoid phytotoxicity affecting plant root development. Then apply 20 cm thick farmyard manure for ploughing. The planting row spacing is 2-2.5m, and the plant spacing is1-1.5m. The plant spacing can be appropriately increased in plain land. Dig a planting pit (60 cm long, 60 cm wide and 60 cm deep), put in seedlings, fill the soil and water it.

2. Chinese rose:

Potted rose should be planted on sandy soil rich in humus and slightly acidic and fertile, and alkaline soil should not be used. Chinese rose flowers like light, and there should be enough sunshine during the growing period, with at least 6 hours of light every day. Otherwise, only long leaves will not bloom, and even if buds are formed, they will not be bright and fragrant after flowering. Water should be dry and wet, not dry and not watered, but watered thoroughly. Chinese rose flowers are afraid of flooding, and there can be no water in the basin, which is easy to rot.

3. Bai Yutang:

Rosa davurica is a flower and plant that likes light. It needs sufficient sunshine, and it should be maintained during its growth. Roses like to moisten but are afraid of dampness and avoid waterlogging. From germination to flowering, you can properly water more, and the soil is moist rather than waterlogged. After flowering, there should not be too much water and the soil should be dry and wet. Pay attention to drainage and flood prevention in rainy season.

Wild rose likes fertilizer, but also endures poverty. In March, 1 ~ 2 times of liquid fertilizer mainly containing nitrogen can be applied to promote the growth of branches and leaves; In April and May, fertilizers mainly containing phosphorus and potassium can be applied 2-3 times to promote more pregnant buds to blossom; After flowering, it can't be fertilized again.

4. Lily:

Sandy loam with fertile soil, Gao Shuang topography, good drainage and loose soil should be selected for planting. Lily is most afraid of waterlogging, so it is necessary to clean ditches and drain water frequently to stop the rain and dry the soil. Topping should be done in time. When lily germinates in spring, 1 strong bud should be left, and the rest should be removed to avoid bulb division.

5. Sunflowers:

Sunflowers are usually sown in March-April, and the suitable temperature for sowing is 18-25℃, and usually sprout about 5-7 days after sowing. Generally, the sunflower is cultivated for 2-3 times, which has the functions of weeding, loosening the soil, breaking the board, retaining water, reducing evaporation, reducing the harm of saline-alkali and so on. 1 intertillage is combined with thinning and fixing seedlings at true leaf 1-2. After fixing seedlings, the second intertillage is carried out 1 week, and the third intertillage is combined with ditching, ridging and ridge sealing.
