Breeding methods and matters needing attention of Fulukao

Fu Lukao is also known as small Sky Blue Hydrangea, Yanlai Red, Jinshan Begonia and so on. It is an annual herb of the Sky Blue Hydrangea family. It is cultivated in gardens all over the country, with short plants and rich flowers and colors. It can be used as plant materials for flower beds, flower borders and rock gardens. It can also be used as potted plants for indoor decoration. Taller varieties of plants can be used as cut flowers. Let's take a look at the breeding methods and matters needing attention of Fulukao.

The growth habits of Fu Lu Kao

Fu Lukao is originally from Mexico. It is cultivated in gardens all over China. It likes light, cold, mild and humid climate, not resistant to heat and heat, good drainage, easy soil, drought, waterlogging, salt and alkali. It can survive and grow on barren yellow sand land even if there is no rain for many days, and it can survive the winter in North China.

The Propagation method of Fulukao

Fu Lukao usually uses sowing and reproduction, and the prepared bed soil is first disinfected. Potassium permanganate, formalin, dimethazone and so on can be used to spray the seedbed with an appropriate proportion of aqueous solution. The bed soil has been sifted, the bed is leveled, and the bottom water is poured. After the water seeps, the seeds are evenly sown on the seedling bed, 750 seeds per gram, and it is best to do some germination treatment before sowing. After the seeds were sown, the prepared sandy soil was evenly sifted on the seedling bed with a thickness of 0.3 cm, then covered with plastic film and arch shed, and the seedlings could germinate in about 7 ~ 10 days.

The breeding method of Fulukao

1. Watering: Fulu examinees should ensure sufficient moisture for a long time, and the basin soil should be kept moist, but because the leaves are relatively dense, do not water directly from the beginning when watering, so as to avoid water in the leaf area. Rainy season can be properly drenched, but should pay attention to timely drainage, so as to avoid the occurrence of diseases and insect pests.

2. Fertilization: during the growth period, especially after coring and pruning, thin liquid fertilizer should be added in time to promote the growth and flowering of branches. Flukao is sensitive to nitrogen fertilizer, too much nitrogen fertilizer will burn the seedlings, so pay attention to write more phosphorus and potassium fertilizer and less nitrogen fertilizer when applying fertilizer.

3, temperature: Fu Lukao can not bear high temperature, the summer temperature above 35 ℃ will appear obvious yellow leaf phenomenon, to appropriate shade, to avoid direct sunlight. However, Fu Lukao is hardy and can spend the winter outdoors in winter, but the winter temperature in some areas is too low, so it is recommended to overwinter indoors.

4. Pruning: when Fulukao grows to about 15 cm, it is necessary to pick the heart, pinch off the top, promote the branches and control the plant height to ensure that the plant type is short, strong and plump. After flowering, the stump of the stem is pruned as soon as possible and the branches are thinned properly to ensure that the germinated new branches can blossom again.

Matters needing attention in Fu Lukao

The main results are as follows: 1. The seedlings of Flukao are not resistant to transplanting. Do not toss about after growing seedlings by sowing method. After growing for 4 weeks, the roots of seedlings are stable and can be transplanted into pots. At the beginning, you can choose a small basin on the left and right forehead of about 10 centimeters, and you can change the big basin when the seedlings grow up.

2. Fu Lukao grows well in a sunny environment, as long as it is pruned in time, the plant type is compact and beautiful, but if there is a lack of sunlight, it may lead to futile growth and grow into a "towering tree". It is possible to spray dwarf element properly, so that the growth of Fu Lukao is not high.
