How to plant banyan seeds
1. Selection of improved varieties: collect the seeds of Ficus microcarpa when the fruit is ripe at 5438+00 every June, spread them out and dry them, then put them in water for about 12 hours to absorb enough water, so as to facilitate the early and orderly emergence of seedlings, and then take out the full seeds and sow them.
2. Level of nursery: Ficus microcarpa is suitable for neutral or slightly acidic soil with loose soil and rich humus. Choose warm and wet fields with good air circulation, sufficient sunshine and convenient irrigation and drainage as nursery land, and level the border.
3. Evenly and thinly sow: evenly and thinly sow the edges of banyan seeds, and then cover them with a thin layer of straw to prevent the rain from washing away. After sowing, it will be watered, and then the border surface will be kept dry and wet alternately to avoid rotten seedlings caused by stagnant water, and it will germinate about 12 days after sowing.
4. Transplanting: When the banyan tree is seven or eight centimeters high, it can be transplanted. Plastic nutrition bags are selected for single plant seedling, which is beneficial to root growth and strong branches. When the excellent seedlings grow to 40 cm high, they can be transplanted into the field for cultivation.
Planting method of banyan tree
1, illumination: Ficus likes sunny, well-ventilated, warm and humid annual rings, drought-tolerant and semi-cloudy. Generally, it should be placed in a ventilated and light-transmitting place, otherwise it will easily make the plants yellow, lead to pests and diseases, and even die.
2. Watering: If the banyan tree is not watered for a long time, the plant will wither due to lack of water. Therefore, it is necessary to observe in time, water according to the dry and wet conditions of the soil, and keep the soil moisture, but not too much water, otherwise it will lead to root rot.
3. Fertilization: Figs like fertilizers, so it is enough to apply more than 10 compound fertilizer every month. When fertilizing, pay attention to burying the fertilizer in the soil along the edge of the flowerpot and watering it immediately after fertilization, but frequent fertilization will also cause harm to the growth of figs.
4. Temperature: The suitable growth temperature of Ficus microcarpa should not be too high day and night, and the temperature difference is 10 degrees, so it is easy to fall leaves and die. Usually put it in a place with light, and shade it properly in summer.
5. Pruning: At the peak of the growth of banyan trees, the seeds should be removed and the buds should be smeared. In autumn, a big pruning should be carried out to cut off long branches, combined branches, weak branches and cross branches. After that, you can omit the pruning.
How to trim banyan bonsai?
Pick a heart
Core picking can promote axillary bud germination, grow more branches, expand the crown, and inhibit the white growth of branches. The time and frequency of coring are closely related to tree species. Such as pine trees, it is advisable to remove about 2/3 of the bud center before the new bud germinates, but only a small piece is left at the base. Two lateral buds will grow here in the future, and new branches will grow in both directions. For evergreen broad-leaved trees and deciduous trees that are prone to sprout new leaves, the leaf core can generally be removed when the new buds sprout and grow 2 ~ 3 leaves. When new branches and leaves sprout again, pick the heart in the same way. This repeated operation can achieve the purpose of making the crown full.
Sparse bud
Sparse bud means that many buds often germinate at the same time in the germination season of trees. In order to ensure the centralized supply of water and nutrients, it is necessary to keep good buds and remove unnecessary buds to form an ideal tree shape. For elm trees, such as trees with vigorous germination in the snow, we should pay more attention to erasing the buds that are not conducive to modeling at any time.
picking leaves
Leaf picking can promote the germination of new leaves. Some tree species, such as elm, Vitex negundo, etc., can make the originally large leaves smaller and more delicate by picking leaves. Some color wood species, such as Acer, pomegranate, etc., can make their leaves more colorful by picking leaves. Removing the leaves, because of removing the photosynthesis of these leaves, will make the stump lose a good opportunity to accumulate nutrients, and for some weak stumps, it may cause the plants to weaken or even die. So it's best to pick leaves from the vigorous stump.
short cut
The method of cutting off some annual branches is called short cutting, which can quickly improve the branching level of branches. Generally speaking, pruning the top layer of branches can make the appearance of trees more full. According to the number of cutting parts, short sections can be divided into short sections, medium short sections and heavy short sections. Generally, 1/5 at the top of the branch is cut off from the short node, and the growth advantage of the top of the branch is removed to form more short branches and middle branches, so that the tree is fuller and the mother branch is thicker. Medium and short cutting generally refers to cutting off 1/2 ~ 3/5 at the top of branches to form more medium and long branches, which may promote the growth of branches. Re-cutting refers to retaining 1/5 of branches, which can promote the growth of 1 ~ 2 vigorous branches cut, and is generally used to cultivate main branches.
Shrinkage shear
The part where the perennial branches are cut off is called shrinkage cutting. Is it Lingnan School? Store branches and cut them off? What are the main pruning techniques for manipulating creation? Chicken feet? 、? Antlers? All kinds of twists and turns, vigorous and powerful shapes. Shrinking and cutting can not only dwarf the tree shape, but also enhance the expressive force of branches, continuously shrink and cut branches and increase the level of bonsai.
