Potted cycad control method

The cycads are also known as the phoenix, because they have a plume-like cluster of stems and a phoenix tail. Potted cycads under daily conservation, the leaves grow large and long, unfavorable to watch, need to expand in its buds, sprout a long new leaves, adequate light, control of water and fertilizer, it will help inhibit the growth and shape of new leaves, and short leaves The leaves are small and tight, so that the new leaves grow downwards and the tip ends inwards, and the form is naturally beautiful.

In early May, select sunny weather, cut all the leaves of cycads, cut the old leaves, and promote the expansion of the top buds, which has the effect of sprouting new leaves in advance. After the new leaves are established and shaped, leaves that are not suitable for viewing should be sparsed to maintain a good posture.

After the cycads trim the leaves in spring and summer, the new leaves are usually between the rainy seasons. At this time, there are more rainwater and rain measures are needed. Prevent too much rain from entering the basin, making the new leaves too big and growing too long to reach the ideal of controlling the leaves. Rain-proof basins can be built with a rain canopy (with a transparent plastic film, not affecting light and ventilation), or remove the rain, and then return to the place where the sun is shining.

The cycads have strong drought-resistance ability. When the new leaves grow, the control of soil water and fertilizer in the pot is very important, and it is also the key to the growth and shaping of new leaves. After the leaves are trimmed, around the beginning of June, the top buds begin to swell, sprout new leaves, grow and shape the new leaves, and strictly control the water in the pots and soils. Controlling the amount of water promotes the slow growth of the leaves and achieves the goal of leaf control. After the water in the basin is fully dried, appropriate amount of water shall be provided. Because the leaves of the potted plants are trimmed, the newly germinated leaves are tender and small, and the amount of evaporation of the water is relatively small. The stems and the fleshy roots also store water, and can maintain the evaporation of water for a certain period of time. Watering should be done at about 10:00 a.m. on sunny days, fill in the appropriate amount of water, and keep the moisture evaporating until about 4:00 pm. It is not appropriate to water in the evening and cloudy days. After the new leaves of the pot plant are grown and shaped, normal water and fertilizer are applied. management.

When the potted plants developed new leaves, the leaves became more light-like and inclined towards the south side. The length of the leaves became high and low, which hindered the viewing. The position of pots should be changed. After the young and young leaves are grown, the slope of the new leaves should be observed. When the slope of the leaves is too large, the potted plants turn from the original north side to the south side and are converted once every 10 days to 15 days to allow the leaves to grow. balanced.

After several years of cultivating potted cycads, the soil will lack nutrients, the roots of the bonsai will be dense, and it will be difficult for the water to infiltrate, and the fertilization will not be easily absorbed. This will inevitably affect the growth of the potted plants. It is usually changed once every two years and should be carried out before and after Ching Ming Festival. Because cycads are hi-iron plants, they can be mixed with earth scraps with iron scraps to gradually infiltrate the iron scraps. It is also possible to apply ferrous sulphate 150 times or so to supplement iron and the leaves will be more glossy and green.

Potted cycads through the above management measures, can make the leaves shorter, tight, curly, beautiful, placed on the desk, several racks, meeting rooms, etc., is pleasing.

[Composition]

The main component of this preparation is human immunoglobulin, which is prepared by cold ethanol fractionation of human plasma from healthy donors. The manufacturing process contains a step to remove anticomplementary activity and a dual viral inactivation process. It contains a suitable amount of glucose or maltose as stabilizer (see table below), but does not contain any antiseptic or antibiotic. The distribution of IgG subclasses is close to the serum level of normal subjects and maintains the bioactivity of Fc fragment of IgG.

[Indications]

1. Primary agammaglobulinemia, such as X-linked hypogammaglobulinemia, common variant immunodeficiency diseases, immunoglobulin G subclass deficiency, etc.

2. Secondary immunoglobulin deficiency diseases, such as severe infection, septicemia of newborn, etc
