1, to understand the morphological characteristics of lotus:
Lotus petals are round and wide, and the flower head is divided into two sides. The leaves are shield-shaped with tiny hairs on the back. When painting lotus flowers, we should grasp these morphological characteristics and show the charm of lotus flowers.
2, choose the right brush:
You need to choose brushes with different properties, such as large, medium and small bucket pens, long front, short front, bristles and wool, to draw lotus flowers. Choosing the right brush as needed can make the picture more natural and smooth.
3, ink and color:
When mixing ink, it is necessary to mix ink with water in a proper proportion, so that the ink color presents different effects. Appropriate amount of white pigment should be added in color matching to make the lotus show elegant colors.
4. Draw lotus leaves:
When drawing a lotus leaf, you should draw the central part first, and then spread it out. It is necessary to master the shape and size of lotus leaves and the change of ink color.
5. Draw petals:
When drawing petals, spread them from the center in all directions, and pay attention to the shape and size of the petals. At the same time, we should master the strength and speed of brush strokes, so that the petals present a light and elegant effect.
6. Draw stamens:
When drawing stamens, draw the distribution of stamens according to the position and shape of petals. Pay attention to the color and shape of stamens and their coordination with petals.
7, master the use of ink and wash:
The application of ink painting is one of the keys of lotus ink painting. It is necessary to master the shade change of ink color and the control of moisture, so that the picture presents a suitable effect of wet and dry.
8, careful observation and adjustment:
When painting lotus flowers, we should carefully observe the morphological characteristics and details of lotus flowers, and constantly adjust the picture effect to make the picture more vivid and natural.
Growth habit and cultivation techniques of lotus.
First, growth habits:
Lotus is an aquatic plant, which likes relatively stable and calm shallow water, lakes, swamps and ponds, and is its suitable place, and does not like fluctuating water. The water demand of lotus depends on the variety. The relative water level of large plant-shaped varieties such as Gulian and Chiba is deep, but it cannot exceed 1.7 meters. Small and medium-sized plants are only suitable for water depth of 20-60 cm.
Meanwhile, lotus is very sensitive to water loss. In summer, as long as there is no irrigation for 3 hours, the lotus leaves planted in the water tank will be sluggish. If the water is stopped for one day, the lotus leaves will be burnt and the buds will wither. Lotus is also very fond of light, and it needs full light environment during its growing period. Lotus is extremely intolerant of shade, so it will show strong phototaxis when it grows in semi-shade.
Second, the cultivation techniques:
1, water quality:
Lotus is an aquatic plant. During its growing period, it can't live without water all the time. At the initial stage of growth, the water layer should be controlled at about 3 cm, and the water is too deep to raise the soil temperature. If you use tap water, you'd better put it in another jar and dry it for a day or two before using it. Summer is the peak of lotus growth, so there is no shortage of water in the basin. After winter, the pot soil should also be kept moist to prevent the lotus root from drying up due to lack of water.
2, fertilization:
The fertilizer of lotus is mainly phosphorus and potassium fertilizer, supplemented by nitrogen fertilizer. If the soil is fertile, there is no need to fertilize all the year round. Rotten cake fertilizer and chicken, duck and goose manure are the most ideal fertilizers. Small pots can only be applied half, and large pots can only be applied 1-2 at most. Never apply more, but mix it with the soil.
In the vigorous growth period, if the leaves are found to be yellow and thin, 0.5g urea per box can be mixed into the mud and kneaded into balls of about 10g, and each pot is applied with 1 granule, which will take effect in 7 days.
3. Overwintering:
After winter, put the basin indoors or under frozen soil. The area north of the Yellow River should be covered with agricultural film except under frozen soil, and the soil in the basin should be kept moist throughout winter.
