Planting method of Fraxinus mandshurica bonsai 1 Water.
Fraxinus mandshurica bonsai should be dry and wet, which is generally used? If you don't do it or water it, it will be complete. For principle. Water Fraxinus mandshurica bonsai as little as possible, usually only keep a certain amount of water in the pot soil, and water more in midsummer. The watering time is mainly in the early morning or morning, so try to avoid watering at night.
2. Lighting equipment
In spring, summer and autumn, Fraxinus mandshurica bonsai must be placed in a sunny place (except for intermittent shading in midsummer to avoid direct glare), and indoor bonsai must also be dried for at least three days. In winter, there must be enough diffuse light to maintain the normal photosynthesis of plants.
3: Ambient temperature
Fraxinus mandshurica bonsai has strong adaptability, and there are no adverse reactions and diseases from low temperature to -20℃ and high temperature to 40℃, so don't care too much about the temperature. But whether it's north or south, it's best to move indoors in winter. Pay attention to replenish water where there is heating.
Step 4 sprout at the right time
Grifola frondosa bonsai has two peak seasons in spring and autumn every year. When everything recovers in spring, ash trees sprout the most new buds. At this time, it is necessary to wipe off the extra buds in time. After a short dormancy period in midsummer, ash trees will usher in the second growth peak in the middle and late August every year. Although there are not as many new buds as in spring, they should be erased in time.
5: Pot soil
After the Fraxinus mandshurica bonsai is formed, the deep basin should be replaced with a shallow basin to minimize the soil in the basin. At the same time, when mixing soil, it is necessary to add more coal slag appropriately, and the ratio of soil to coal can be half.
Step 6 apply fertilizer
In the growing season, thin fertilizer should be applied to Fraxinus mandshurica bonsai frequently, once every 5-7 days, so as to facilitate the absorption of trees and avoid the waste of fertilizer solution. Fertilization time is usually carried out in sunny afternoon when the basin soil is dry, and the leaves are washed with water after fertilization. After the Grifola frondosa bonsai is formed, it is basically unnecessary to fertilize. However, in order not to make the trees too weak, we can apply some thin fertilizer before the ash trees fall leaves in late autumn.
Planting techniques of spinulosa bonsai ⅰ. Botanical characteristics of butt ash
Fraxinus japonicus belongs to Fraxinus of Meliaceae. Zhongxiang and Jingshan, native to Hubei, are deciduous trees, up to 30 meters high. Young and strong bark is smooth, light gray-green, and middle-aged and old bark has longitudinal dark gray stripes. Branches germinate vigorously and are resistant to pruning. Trees are drought-resistant, moisture-resistant, heat-resistant, like fertilizer, water and sunshine, and can be cultivated in the open field south of Beijing. Suitable for neutral and weakly acidic soils, with a PH value of 5? 7。 Sowing and cutting propagation.
Secondly, the treatment and cutting propagation of Fraxinus mandshurica downhill piles.
Fraxinus mandshurica stumps bought from far places of origin were dug by mountain people in winter and early spring. Local cultivation excavation time can be excavated except from mid-June to mid-August. Generally, the protection measures of mountain people during excavation and transportation are poor. Although this tree species has strong vitality, in order to obtain a higher survival rate, we still need to pay attention to its dehydration in different degrees. First of all, the hurdles should be in place at one time. This kind of tree takes root easily, and it can grow fibrous roots through a cut with a root diameter of 200 mm. Therefore, the root branches that hinder the future pot shape should be sawed off decisively. Secondly, we should absorb enough water. If possible, it is best to put the roots upright in water dissolved with rooting agent (such as rooting powder and vitamin B 12), and the treatment time shall be subject to the instruction manual of rooting agent. Or soak the whole pile in clear water for a day and a night, and then plant it in a sand bed for maintenance. The root burial depth should be more than 20cm, and the old piles and dry piles with dry diameter greater than 20cm should be deepened appropriately. Pile arrangement distance: the spacing between medium-sized piles should be greater than 0.5m, and the spacing between large-sized piles should be greater than1m.. This is conducive to the extension of branches, otherwise the branches cover each other, which is not conducive to growth and pruning operations. Thirdly, after planting, it should be filled with water, so that the sand can be in close contact with the root gap. At ordinary times, the sand bed should be kept moist and the trunk should be watered frequently. If 30%~50% sunshade net is used for protection, the effect will be better. Generally, it will germinate in late spring and early summer. After beginning of autumn in early August, you can take off the sunshade net and let it enjoy the sunshine. From the end of April to the beginning of May, if there are still uncleaned stumps, scrape off their bark with a knife. If the top bark is still emerald green instead of yellow, pull it out of the sand bed. After soaking sand in clear water for a day and a night, it can be planted in a semi-cloudy and semi-sunny place for maintenance, which can still promote germination and survival.
In order to protect the ecological environment, sowing and cutting propagation are now advocated. Sowing is suitable for large-scale propagation. You can refer to the garden technical data. Bonsai lovers are more likely to propagate by cutting, which is carried out in winter and spring. Use annual robust branches, cut 10cm~ 15cm long before germination, insert them into sand bed, shade them properly, water them frequently, and keep the sand bed moist. It can take root in more than 30 days, and can be transplanted to the field for cultivation in mid-May. It can also be planted in summer and autumn, but it must be shaded to keep the sand bed moist, which is a bit difficult to manage.
Thirdly, pruning and shaping of ash stumps.
The new buds germinated in the first year should be treated according to the strength of the sprouting branches of each stump.
For Wang Shu, usually after beginning of autumn in early August, when most branches grow to more than 40cm, the branches are fixed, leaving the branches in line with the modeling direction, leaving 1-2 branches for the clustered branches, and removing the rest. If it is found that there are no branches in the part that needs to be branched, the redundant branches at the lower part of the trunk can be docked with the missing branches. The lower molding branch should be pulled in place with rope or aluminum wire. At this time, it is best not to bind the shape by winding. Due to the rapid thickening of Rhus verniciflua branches, they will be trapped if they are not careful, which will affect the beauty and growth of the first-class branches. According to the planting pile area, apply urea fertilizer every other week, per square meter 10g ~20g, to promote the new branches to be strong. Since ash trees can grow when the daily average temperature is above 150c, if there is enough water, fertilizer and sunshine, the diameter of the flourishing branch base of the new pile can reach more than 20mm when it comes to frost. Therefore, for the terminal branches, the tip should be controlled first (for the rapidly formed commercial piles, the first-grade branches can be cut and the second-grade branches can be cut at the end of the year). Thick branches are needed at the bottom, and other parts are left for growth. In the process of management, it is necessary to observe at any time and find that the redundant branches sprouting at the base of the main branches should be erased in time, otherwise the crazy branches will suddenly grow and consume nutrients in vain, which will affect the growth and thickening of plastic branches. After the frost leaves fall, you can go to the basin. Dig out the pile material from the sand bed, shake off the gravel at the root, cut off the long roots and branches. According to the size of the pile, fill in nutrient soil, and add a fence on the shallow basin to prevent the fibrous roots from exposing the soil surface of the basin. Finally, water adequately and strengthen overwintering management. If the sand bed is not in a hurry, it can be trimmed in winter, and it is better to go to the basin on the eve of spring germination.
For weak branches, although they germinate and sprout, the roots do not grow or grow sparsely, so they should continue to be planted in sand beds until the roots and branches grow vigorously in the next year. Don't rush to prune the pot, it will affect the survival rate.
Management method for sowing and seedling raising of ash tree
Spring sowing should be early, usually from late February to early March. Ditching and drilling, the seed dosage is 3 ~ 4 kg per 667 square meters, the depth is 4 cm, and the depth should be uniform. Trenching, sowing and soil covering should be carried out, with a thickness of 2 ~ 3 cm. In order to make the soil closely connected, the soil was covered and pressed.
Cutting seedling
It is held from the end of March to the beginning of April in spring. Before cutting, the soil is carefully prepared and applied with sufficient base fertilizer to make the soil loose and full of water. Select 1 annual budding branches from healthy young mother trees that grow rapidly and are free from pests and diseases. Generally, the branches are thicker than 1 cm and longer than 15 ~ 20cm. The upper incision is flat and the lower incision is horse-eared. Insert 2 ~ 3 cuttings into each hole, so that the cuttings are dispersed, with a row spacing of 40 cm and a plant spacing of 20 cm. In spring, cuttings should be deeply buried, compacted and exposed, and 4 000 cuttings should be inserted every 667 square meters.
