Place of Origin: Weizhou Island and Xieyang Island, Beihai City, Guangxi Province have a large area of ​​natural growth. Leucaena is an excellent woody feed tree belonging to the common Leucaena (hawaiian shrub type). In 1964, the introduction of arborescent El Salvador-type new Leucaena in Guangxi, performed well and gradually promoted planting throughout the region. Botanical features: New Leucaena is a perennial tree. Plants are tall, with many branches and leaves, plant height 3 to 5 meters, up to 10 meters, stems about 10 centimeters, and up to 25 centimeters or more. Bark grayish yellow. The main roots are well developed, and the leaves are evenly feathered, with 5 to 7 pairs of pinnacles. Each pin has 10 to 17 pairs of lobule, and there are gland points, IJ, and f are 1.5 cm wide and 0 wide. .4 cm, dark green leaves, shallow backs, flower heads, white, pods flat, banded, containing 15 to 25 seeds, seeds flattened, melon-like, smooth, brown, 1000-grain weight 50g. Biological characteristics: Ginseng warm and humid climate, the optimum growth temperature is 20 ~ 30 °C, the temperature is higher than 35 °C, still able to maintain growth, below 12 °C, slow growth, growth below 8 °C, minus 3 °C and moderate frost , Still able to endure, heat and cold resistance, Guilin South winter is not fallen, there are leaves in northern Guangxi, spring weather is picking up, return to early morning, germinating new branches quickly. Drought-resistant, not flood-resistant, poor growth in low-lying areas. Strict requirements on the soil, the best growth in the neutral to slightly alkaline soil. In the acidic (PH5 ~ 65) red soil can still grow. Feeding value: The new silver acacia branches, leaves, beans, and wolfberry are rich in nutrients. According to laboratory tests, the branches and leaves contain 21.0 to 29.1% of crude protein, 21.7% of soybean meal, and 38% of beans, and lysine in stem and leaf tissue. 2l%, methionine 0.96%, cysteine ​​023%. The output of fresh grass (branches and leaves) is 3,000 to 5,000 kilograms, and it can be harvested 3 to 4 times a year. The seed yield is 50 to 100 kilograms per mu and it is harvested twice a year. Leucaena leucocephala can be grazing green feeding, but also grazing, cattle, sheep, rabbits like to eat. Leucaena contains mimostin, which is toxic and can be fed only for a long time. The livestock can become poisoned, showing hair loss, excessive salivation, and slow growth. Under grazing conditions, cattle and sheep eat moderately without symptoms of poisoning. In addition, in the rumen of long-term ingested leucaena, there is a kind of mimosin-digesting bacteria that is inoculated into the rumen of other beef cattle to form detoxification and has a complete detoxification capability for leucaena. Leucaena is also a fast-growing, good-quality species with many uses such as green manure, covering, fuel, afforestation, and conservation of soil and water.
Black Light lamps called BL light in short.
A black light is an Ultraviolet Lamp. It is called a 'black' light because the ultraviolet light is outside of the visible spectrum. When you shine a black light on some objects, they glow very brightly because they are fluorescent or phosphorescent.
The Black Light UV Lamps effciently emit ultraviolet rays at 315nm-400n,the peak 352nm.
Application:used for trapping insects,luring lamps.
