Bonsai Teaching: the cultivation method of Metasequoia bonsai

Many people care about bonsai, only care about its beauty drift, but the environment is not healthy, the beauty of bonsai lies in its natural beauty. Since potted landscapes range from potted plants to basins, God is destined to grow in a very limited space and nutrients are limited, so more careful care is needed. Potted soil quality is an important factor determining the root development of potted plants.

At present, many bonsai enthusiasts are not particularly particular about bonsai. Pot soil is not suitable for pot growth, pot growth slow, unhealthy. When many people are planting bonsai, the pile will plant the bonsai directly in the soil. The water, oxygen and nutrients in the soil are insufficient, and time is easy to set. If kept in the yard for years, it won't drain during the rainy season.

It is unhealthy to live in bonsai long, plus the last few years will not change the bonsai will die. Basin soil selection is based on three principles: strong water storage capacity, strong drainage capacity and good ventilation performance. The average cutting length is 10~15 cm, the upper end is straight, 1 cm from the bud, and the bottom is inclined. Cuttings on the branches are better in the young shoots and middle, inserted at harvest time. In order to improve the survival rate of cutting of Metasequoia glyptostroboides,

In addition to growth hormone therapy,"hibernation" is usually used. In winter, the fruiting branches are cut from the mother tree and cut into cuttings. Bundles 60 to 100 in each, depending on thickness, select leeward, sunny and drainable locations, dip the bottom of the bundle into the foundation, bury the soil in wet sand, and cover the roof mat to prevent soil freezing rain and snow from entering the RO. TTEN practice proved that Metasequoia glyptostroboides tissue softened after winter storage.

Cuttings take root easily, which is beneficial to improve survival rate and seedling rate. After cutting, the temperature rise is very small. As long as the seedbed is properly watered and kept moist, there is no need for immediate shade. This raises the temperature of the soil and is conducive to rooting. In late April, shadows begin to occur. After the dog, the sun shading time gradually shortened. After the first half of September, it will no longer be obscured. Weed the grass regularly.

After rooting, 2~3 topdressing was used to promote seedling growth. 1. 200 times or 50% moisture removal powder can control Metasequoia wilt, 50% moisture removal powder, plum 4~5 times at the end of rainy season, once every 10~15 days can control disease occurrence. To control the large pocket moth, kill the larvae with 800~1000 times dipper or 1000 times moth. Softwood cutting: can be done in mid-May and early summer.

Early morning 14-18 cm long shoots are cut from the expanded part of bud scales at the bottom of the shoots, the excess leaves are trimmed, leaving only the top 4-6, the cut base is soaked with 300-500 mg/L NAA for 3-5 seconds, and then inserted into the seedbed, 6. 7 cm deep, 180~200 plants per square meter, watering feet and keeping the base. The quality is moist. It can be sprayed 3-5 times a day depending on weather conditions, or covered with small ring sheds covered with moisture, usually 20-50 days of natural roots. After rooting, the small ring shed should be removed every 20 days and then transplanted in the second half of the year.
