Tulips are unique in that they take root in winter and sleep in summer; flowers bloom during the day and close at night and on rainy days. Tulips are warm and humid in winter, slightly cooler in summer, slightly sunny in shade and sunny in shade, and are more resistant to cold and heat. It is the fine flower of the forest park landscape.
Its requirements for soil conditions are: deep soil, loose and fertile, well-drained sandy loam soil, avoid low-viscosity soil. The pH value should be moderately alkaline (if it is grown in acidic soil, it should be mixed with appropriate amount of lime).
Second, cultivation techniques Planting: It is appropriate to carry out in autumn. Can be planted, potted. Fertilizer bulbs should be selected as a bulb. Pots can be planted with 3 to 5 pots per pot according to the pot diameter, and the planting depth is suitable for flushing the top of the bulb with the soil surface. If the bulbs are not refrigerated, they should be normalized after naturalization in the low temperature environment.
After the seeds are planted, the root water should be poured. After the early spring buds have sprouted, the amount of water must be sufficient and balanced. The soil should be kept moist and not able to hit the water. If the long-term lack of soil moisture will inhibit the growth, resulting in short, short flowers, small flowers. It even produces "blind flowers." Watering time should be before 9am.
In the planting time, in addition to the application of base fertilizer, the 1% concentration of quick-acting compound fertilizer should be applied once during the four periods of sprouting, spreading leaves, buds and flowers. In the bud stage, the application of 0.2% potassium dihydrogen phosphate solution twice to three times every 5 days to 7 days on the leaf surface can effectively improve the flowering quality.
In addition, if you want to flower early in the winter or early spring, you can use the bulbs that have been treated at low temperature, and promote cultivation in the greenhouse for 50 days to 60 days in advance. The cultivating substrate is mixed with stone (or sand) and humus, and the pot is sterilized. After the soil is covered with the top of the bulb, it is first cured at 9°C-12°C for 30 days to promote bulb rooting, and then the pots are placed in a greenhouse where the light is sufficient. The temperature is kept at room temperature about 20°C for about 30 days. Can blossom. In order to promote the cultivation of the basin, we must keep it moist, and we must not dry it. After leaf spreading, the leaves were sprayed with 0.2% potassium dihydrogen phosphate solution twice to three times, and normal flowering could be achieved without the addition of other fertilizers.
Ball harvesting: After June, when the upper stems were yellow and the outer surface of the underground stems turned light brown, the bulbs were excavated, and after drying, the clods and residual roots were removed and sterilized with 0.1% potassium permanganate solution. Minutes, then store in a cool dry place. The temperature during storage is preferably around 20°C. Long-term over 23°C or below 17°C will be detrimental to the growth and blooming of the second year. After entering August, the temperature may gradually decrease to 15°C.
Buy bulbs: plump bulbs, bright skin without damage, no traces of pests, and bulbs with a diameter of 3 cm or more are good quality bulbs. If you want to flower early before February, you need to buy cold-treated bulbs.
What is AHD?
AHD is short for Analog High Definition, so AHD camera is analog high-definition camera, transmission signal is the high-definition analog signal. Talking about high definition, in short, we usually call the video high definition with the physical resolution more than 720p, referred to as HD.
AHD technology can achieve the reliable transmission of ultra long distance (500 meters) high-definition video signal on the existing analog transmission line. It adopts advanced Y/C signal separation and simulation filtering technology, which can effectively reduce the color noise in high frequency area, image reducibility is better. Compared with the traditional high definition products, AHD camera image quality has a qualitative leap and upgrade, the highest clarity can be equivalent to the full network HD 1080 level.
AHD camera follows the method of simulating standard definition transmission, which can reduce the complexity of construction and deployment, reduce the cost of auxiliary materials and maintain complexity as well as technical requirements of construction personnel. It is extremely suitable for upgrading the old system, you can easily upgrade from standard definition to high definition without change the original system . In addition, high definition quality with standard defintion price, make the AHD camera has a very large development space both in the civilian and industrial market ( such as AHD Car Camera ).
