Characteristics come from the fact that nature is higher than nature.

Both form and spirit, expressive.

Trunking and storage branches are unique.

In the form of stump bonsai,

Stump bonsai can be divided into straight stem type, horizontal stem type, inclined stem type, curved stem type, cliff type, stone attached type and vertical branch type according to the types and characteristics of the quantity used and the characteristics of design and production.

Trunk straight: The trunk is upright or basically upright. This kind of trunk is allowed to grow to a certain height for coring, so as to achieve the effect of clear hierarchy and good density. Usually divided into single trunk, double trunk, three trunk and multiple trunk.

Lying dry: the trunk is lying horizontally, and the whole plant is in a recumbent state, with unique posture and simple and elegant expression.

Inclined trunk type: the trunk is inclined but does not lie down, the crown is inclined to one side and the tree is stretched. The common thin shadow of plum-entering pile inclines laterally.

Bending dry type: the trunk is bent and the tree is full of changes. The common form is "trilogy", which looks like the word "zhi".

Cliff type: the trunk leans out of the basin, and the crown hangs like a hanging object. According to the degree of trunk hanging upside down, there are big cliffs, small cliffs and half cliffs.

Rock-attached type: a rock plant, in which trees are planted on rocks and stuck in cracks to imitate.

Pendulous branch type: suitable for tree species that are longer than paper strips, such as winter jasmine, weeping willow and pendulous peach. And use their natural drooping branches for proper treatment.

Water and fertilize the stump bonsai.

1. water

Watering is one of the most important and commonly used measures in the management of stump bonsai. Stump is planted in a pot, whether it is deep or shallow, the soil is always limited and the water content is limited. If you don't water for a long time, the stump will wither due to lack of water, so you should observe it in time, water it according to its soil dryness and wetness, and keep the soil moisture. Of course, watering should not be excessive. If you water too much, the pot soil will be too wet for a long time, which will easily lead to hypoxia and rot of the root system. At the same time, the amount of watering depends on different specific tree species, seasonal changes and cold weather. Generally speaking, in summer or drought, it is best to water it once in the morning and evening, once every day or every other day in spring and autumn, and once in the morning and evening when the stump germinates in spring. In rainy season or rainy day, you don't need to water, but also pay attention to drainage. Sandy soil can be watered more and cohesive soil less. Watering can be done by spraying water on leaves or irrigating roots. Generally the two are combined. First, spray water on the leaves, and then thoroughly irrigate the roots. Be careful not to pour "half water" to make the basin surface dry and wet, and don't spray too much water on the leaves, which will easily lead to too many branches and leaves.

fertilize the soil or land

The soil in the stump bonsai basin is limited, so the nutrients are limited, so we should pay attention to the supplement of fertilizer. Because of its artistic characteristics, stump bonsai should not be fertilized too much and too frequently. It is necessary to master the contents and types of fertilization and grasp the fertilization season. The three elements of plant growth nutrients are nitrogen, phosphorus and potassium fertilizer, and nitrogen fertilizer can promote the growth of branches and leaves of stumps; Phosphorus fertilizer can promote the formation of flowers and fruits; Potassium fertilizer can promote the growth of stems and roots, so the choice of fertilizer should be based on the type of stump and its growth trend.

To make the stump flourish, you can apply more nitrogen fertilizer; If the stump needs more flowers and fruits, the content of phosphate fertilizer can be increased; Strong roots are needed, and more potassium fertilizer can be applied when it is developed. Fertilization methods are generally divided into delayed fertilization and rapid fertilization. Generally speaking, slow-release fertilization is to mix organic fertilizer into the soil according to a certain proportion after crushing and decomposing, and mix it into the basin when changing the soil to make it provide nutrients slowly; Quick-acting fertilization is to dilute organic fertilizer or chemical fertilizer, and apply fertilizer according to the seasonal growth needs of stumps, but be careful not to be too thick. Newly planted stumps are not suitable for fertilization in this way. Fertilization in rainy days will lead to the loss of fertilizer efficiency and the effect is not good.
