How to raise the "plant gold" yew? What are the points for attention?

Taxus is an endemic tree species in China, and it is recognized as a natural rare anti-cancer plant on the verge of extinction in the world. It has higher growth conditions, slower growth and poor regeneration ability, so now there is no large-scale breeding base. So how to raise the "plant gold" yew? What are the points for attention?

First, how to raise the yew

1. Suitable soil

Taxus is a shallow root plant, the main root is not obvious, the lateral root is not developed, so the absorptive capacity is weak, the demand for soil is high, if the soil is poor, the growth will be affected, good soil can promote its rapid growth, it is appropriate to choose soil loose, fertile, humus-rich slightly acidic soil, the best pH value is between 5 and 6.

two。 Light

Taxus is a light-loving plant, which is sexually fond of sufficient light, which is disadvantageous to growth in a dark environment. It is suggested to breed outdoors, or to build a greenhouse and use facilities to carry out daylighting. Taxus likes light, but avoid strong light exposure, exposure will make it lack of water, when it is serious, leaves wither and fall off, it only needs to provide scattered light when planting, and facilities such as greenhouses can be used to achieve lighting requirements.

3. Fertilizer and water management

If you want the yew to grow fast and well, fertilizer is indispensable. Fertilization is usually three months after planting, because at this time the soil fertilizer can still supply the growth needs, if fertilization may cause fertilizer damage and lead to overgrowth of plants, it is recommended to make fertilizer into solution and apply fertilizer in the early stage of fertilization, which can improve the utilization rate of fertilizer, let the plant absorb quickly, and control fertility and moisture. In the later stage of growth, fertilizer can be applied directly, and the fertilizer is mainly organic fertilizer.

4. Pest control

When breeding, it is often harmed by diseases and insect pests, which has a great influence on the growth rate of plants. the more common disease is root rot, and the appearance of the plant can not be seen at the time of the disease. in the later stage of the disease, the leaves of the plant wither and yellowing, and the root system will be found to be rotten by digging up the root system. At this time, the root system is weak, so the prevention of diseases and insect pests is the main thing. Bordeaux liquid can be sprayed every season, and the damage of diseases and insect pests should be dealt with in time. So as not to miss the best time for prevention and control.

II. Points for attention

1. Don't leave it in the bright light for too long.

Yew because the tree is small to pay attention to the regulation of light, but can not be too long in the strong light, generally summer and autumn before 10:00 or 5: 00 every day after about two hours can, usually accept more scattered sunlight, otherwise, because of strong light burns leaves and leaf tip scorched yellow, and maintain indoor ventilation, as a result of indoor air is too dry and atrophy, sagging and other bad growth phenomenon.

two。 Don't water too much.

If the young leaves of the new bonsai are dark yellow and dull, the withering phenomenon of the top of the new shoot is generally caused by overwatering too much soil and impermeable so that some of the roots rot and absorb water. If the ability to absorb fertilizer is weakened, the amount of water should be controlled if the symptoms are mild, and gently pick the basin surface soil with a hard and blunt object to make the basin soil breathable, move to a place that can accept dew every night, and move to a shady place at eight or nine o'clock in the morning, which is conducive to the healthy growth of the root system. If the leaves are yellowed and curled in a short period of time, it means that the root rot is serious, because immediately turning the basin to check the root rot condition, such as more than half of it, generally can not be saved.

3. Watering should be thoroughly watered

Yellow leaves occur in the old leaves from the bottom up, but the new leaves generally grow normally, generally without one-time watering, and too little watering is caused by lack of water in the roots. Sometimes the top leaves dry and curl and touch the dried leaves, but the old leaves grow normally and are generally caused by the lack of water in the roots. It should be watered thoroughly at one time. When watering, the cracks along the basin must be compacted with objects to prevent the water from quickly leaking out from the cracks. Create the false impression of being watered through. For a long time, the roots will die due to lack of water, move outside at night to accept more rain and dew, and receive two hours of sunlight sooner or later to restore the growth of the yew.

4. Alkaline water should not be poured for a long time

Taxus is suitable for weakly acidic soil. If it is irrigated with alkaline water for a long time, it will cause the leaves to change from green to yellow, and even the leaves will fall off. Due to the addition of acidic nutrients or spraying leaves or watering basin soil with ferrous sulfate solution of 2DB 1000, once every ten days, three times in a row, the leaves due to alkali yellow can turn green.

5. Pick the buds in time

In March and April every year, the yew will sprout a large number of buds and consume a lot of nutrients. At this time, the buds growing toward the inside can be removed to prevent the branches from being too dense and unventilated to make the leaves yellowing or falling off. Transparent light, and can save the excessive consumption of water and nutrients, it is best not to spray liquid fertilizer on the leaf surface at the beginning of bud germination, or to pour thick fertilizer on the root.

The above is the introduction of Tuliu net to the matters needing attention in the cultivation of Taxus mairei. If the normal amount of fertilizer is applied only with urea and nitrogen fertilizer, the concentration is generally 1 × 1000, and if only potassium dihydrogen phosphate is used, the concentration is 1 × 1000-2 × 1000, with an interval of 7-10 days.
