Pls is the Beiluan tree a child 30

Trees that do not have the scientific name of the northern tree, so it may be a commonly used greening tree species ,,, cypress.

Friends are talking about the North Luan Tree, the North Luan Tree: the North Luan Tree, the North Luan Tree, also known as the lantern flower, the black leaf tree, the old wood buds, etc. Introduction:

It belongs to the genus Luanshu in the family Sapindaceae. The northern luan tree is a deciduous tree with a straight tree shape. The branches and leaves are lush and beautiful, and the young leaves are mostly red leaves in spring, and the trees are full of yellow flowers in summer, and the leaves turn yellow in autumn.

The northern luan tree has strong suitability and distinct seasons, and is a completely green, foliage tree species.

Introduction. After thousands of years of freedom, the illusion world finally entered the state of separation of the three kingdoms, and then the six countries competed for power, and people began to live without freedom. . . Beishu, as a great man, has no ambitions, just wants to marry a wife and have children, and live a plain life, but after all, he was pushed to the stage by history and began his great journey as the founder of the kingdom of the illusory realm......

Plant growth three elements, nitrogen, phosphorus and potassium.

Expansion: Luan grows in calcium-based soils produced by limestone weathering, is cold-tolerant, and is only distributed in the lower reaches of the Yellow River Basin and the Yangtze River Basin in China, and is rare in the north of the Haihe River Basin, nor can it grow in silica-based acidic red soil areas. Luan trees germinate late in spring and fall early in autumn, so the annual growth period is shorter and the growth is slow, the wood can only be used to make some small utensils, and the seeds can be pressed for industrial oil.

1. Shading The shading time and shade degree should depend on the local temperature and climatic conditions at that time, so as to ensure that the seedlings are not harmed by sunburn.

In order to improve the degree of lignification of seedlings, the seedling management technology of northern Luanshu [1] should gradually extend the light time and light intensity until full light is received.

Second, seedlings and seedlings seedlings grow to 5 10cm high seedlings to be seedlings, with a distance of 10 15cm between seedlings combined with watering and top dressing, leaving about 12 seedlings per square meter. The seedlings are required to be small and large, to the inferior and to be excellent, to be dense and sparse, and to be equidistant from all seedlings, and to carry out it on rainy days. Combined with the seedlings, the missing plants were supplemented to ensure the uniform distribution of seedlings.

Third, daily management to often loosen the soil, weeding, watering, keep the bed moist, most of the seedlings in late autumn after the fall of leaves can be as high as 2m, the diameter of the ground is about 2cm. The seedlings are dug up and graded, transplanted in the spring of the second year, the roots are slightly shortened before transplantation, and the seedling stems are cut off from the rhizome after transplantation, that is, the stubble is leveled from the surface, and then watered thoroughly. After germination, the buds should be wiped frequently, leaving only the strongest bud to cultivate into the main stem.

During the growing season, the soil is often loosened, weeded, watered, and topdressed, and a straight trunk can be grown in autumn.

Fourth, transplantation sprout transplanting can promote the development of seedling roots, and the annual seedling height is 50 70cm. Luan is a deep-rooted tree species, which should be transplanted multiple times to form a good and effective root system. After the seedlings are sown in the autumn of the same year, they can be dug into the ditch and planted in the next spring.

Since the trunk of Luan tree is not easy to grow straight, it is necessary to cut off the stubble and strengthen the fertilizer and water management when transplanting for the first time. In spring, shoots sprout and tiller from the base, and those who are straight and strong are selected to grow into the main trunk, and the main trunk grows quickly and straight. If the first interception does not meet the requirements, it can be cut off again in the spring of the second year.

After transplanting, it should be transplanted every 3 years or so, and the taproot and thick lateral roots should be appropriately cut short during transplantation to promote the development of new roots. The growth of young Luan trees is slow, and the first two transplants should be planted appropriately and densely, which is conducive to cultivating a straight trunk and saving land. After that, it should be appropriately thinned and a good canopy should be cultivated.

5. Fertilization Fertilization is an important measure for cultivating strong seedlings. After the seedlings are unearthed and grow roots, they should be fertilized frequently in combination with watering. During the peak growth period, nitrogen-based fast-acting fertilizers should be applied to promote the vegetative growth of plants.

In autumn, nitrogen fertilizer should be stopped, phosphorus and potassium fertilizer should be increased, so as to improve the lignification degree of plants and improve the cold resistance of seedlings. In winter, it is advisable to apply farmhouse organic fertilizer as base fertilizer, which not only provides effective nutrients for the growth of seedlings, but also plays the role of heat preservation and soil improvement. With the growth of seedlings, the amount of fertilizer should be gradually increased to meet the nutrient demand for seedling growth.

The leaves of the flowers I just bought are yellow, if it is a ready-made potted plant:

Whether it is cultivated in a place with weak light and lack of photosynthesis.

Whether it is watered too much, waterlogged roots have appeared.

This is mainly a two-way comparison, because it is impossible to lack anything in a very short period of time just after buying back.

If you don't bring soil to buy it home and plant it in a pot yourself:

The soil should be suitable for the plant.

After the first watering, it is necessary to control the subsequent watering with a degree of dryness and wetness, and place it in a place with good light and avoid strong direct sunlight and wait for recovery (do not fertilize before resuscitation).

It is normal for plants with injured roots to have yellow leaves for a period of time before heavy recovery, as long as proper watering and fertilization are given after recovery, it will gradually regain its leaf green and germinate new leaf buds.

Supplement: Lovers of beginner cultivation can basically become a cultivation expert as long as they simply master the following three points:

Everything grows by the sun, plants, and there are only differences in the strength and weakness of the demand. If the dark room is left without light for a long time, any plant will die.

Soil is the root of the plant – the plant, and only has the unique adaptation to the soil quality. Hydroponics is about appreciating how plants die gradually.

Water is the lifeblood of plants - plants, which are divided into aquatic, Zephytic and xerophytic. Watering a xerophyte every day is tantamount to flooding it.

Fertilizer is the nutrition of plants - plants, adapted to light, more like slightly acidic. Organic fertilizer is preferred, and chemical fertilizer should be very little less than the edge of the pot.

Northern Luan:

Morological characteristics: Luanshu is up to 15 m tall and up to 1 m in diameter at breast height; The crown is nearly spherical, the bark is grayish-brown, and the longitudinal lobes are finely lobed; odd pinnate compound leaves alternate, sometimes part of the leaflet deeply lobed into incomplete 2 pinnate compound leaves, leaflet ovate or ovate-elliptic, apex pointed or acute, leaf margin coarsely serrate, often deep lobes near base; The surface of the leaves is dark green, and the dorsal surface of the leaves is sometimes hairy along the veins; 6 July.

Unlike, Luan tree is a northern tree species, native to Liaoning, I have come into contact with two kinds of Luan tree, one is the ordinary Luan tree, and the other is Huangshan Luan!

In many cases, leaf rolling is caused by the lack of water, not that the surface water is not transported to the orange foot, but that the trunk is blocked by pathogens. The water reaches the canopy from the roots without clumps. It is a soil-borne disease.

My freshly planted this year also rolled leaves, how did you solve it.
