(I) Morphological characteristics: Perennial grasses. Roots short, fleshy. Ye Jisheng, strip or long lanceolate, apex acuminate, base amplexicaul. The calyx is extracted from leafhoppers and is 30-60 cm long. It often grows into a lychee and grows at the apex. Flowers white, spring and summer flowering season, winter flowering at room temperature.
(B) habits: hi warm and humid and semi-negative environment, not cold. Lax soil requirements, like loose loose fertile sandy loam.
(III) Cultivation Management: The warm and humid climatic conditions of Chrysanthemum Hi is not cold nor hot. The optimal temperature for growth is 20-24°C. At this time, the growth is fastest and it is easy to pump litchi. The growth stopped above 30°C and the leaves often had yellow tips. If the temperature is kept above 12°C in winter, the plants can grow normally and the leaves are left to flower; if the temperature is too low, the growth is retarded or dormant; if it is lower than 5°C, it is prone to chilling injury.
Chlorophylin resistance is strong, usually grown very well at half shade. Avoid direct sunlight during the summer so as not to cause the leaves to scorch or even die. At the end of the fall, you should enter the greenhouse and put it in a place with strong light to prevent the lack of light. The leaves will be soft and thin, and the leaf color will be light green or yellow-green, making the pattern of gardening varieties unclear.
Watering should be based on the principle that basin soil is always kept moist. If the potted soil is too dry, the tips of the leaves will turn black. The potted soil will be too wet for a long time and it will easily cause rot defoliation. Chlorophytum is humid and the air is often sprayed with fresh water in the air-dry areas throughout the year to keep the foliage clean and increase the humidity of the surrounding air, which is conducive to photosynthesis and has obvious effects on increasing the growth of leaves and flower buds. Generally spray water 3-5 times a week, each time spraying water to wet the leaves is appropriate. If winter Chlorophytum is to be kept in a room with heating equipment, the leaves and leaves should be sprayed with warm water every 2-3 days to keep the leaf surface moist and clean.
During the peak season, apply nitrogen fertilizer-based thin flower fertilizer or cake fertilizer every about 7-10 days. Fertilizer should not be concentrated. When liquid fertilizer is applied, the leaves must be picked up so as not to spill the liquid fertilizer onto the leaves and burn the leaves. After each fertilization, it is best to use fresh water spray to clean the foliage.
Potted soil is best to use water-retaining acid leaf rot. It is possible to use 3 parts of rot leaf, 4 parts of garden soil and 3 parts of sandy soil. The root growth of Chrysanthemum sp. grows quickly and should be changed once a year to remove dry rot. And extra roots. 4-5 years update once.
Chlorophytum can also be cultivated. Pour the plants from the pot, rinse the roots and clean the soil, place in a transparent container, change the water once a week, and add a small amount of potassium dihydrogen phosphate to the solution. Water cultivates orchids, both foliage and root, and they serve two purposes.
(d) Breeding: sowing and propagation can be used.
1, sowing propagation: sowing seedlings quickly, the temperature is about 15 °C, about 15 days that can germinate, but the seedlings grow more slowly.
2. Breeding of Strains: Strains can be grown in the greenhouse all year round, often in spring when combined with basin replacement. The old plant, which was planted for 2-3 years, was divided into several bundles and each pot was placed on the upper pot; the young plants with aerial roots could also be cut directly from the litchi and topped with pots. Do not put too much soil on the pot, and plant 3 pots. Slow the seedlings before the shade. After the growth is resumed, move them to the shade. This method is simple, fast seedlings, so commonly used.
(E) pests and diseases: spider mite pests and diseases, mainly physiological diseases, the tip of the yellow leaves, fertilizer and water management should be strengthened. Always check and remove the scale insects and whiteflies on the leaves in time.
Glass Venlo Greenhouse is Spire-type glass design, design and installation of windows when more convenient and easy. Its roof slope andle can be appropriately according to the local real climate change the environment.
In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. the steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using 4 mm thick float glass.
