Ryegrass has good quality and good palatability. It is not only cattle, sheep, pigs, rabbits, geese, chickens and other livestock and poultry, but also a good feed for grass carp. Ryegrass has great potential for yield increase. Under conditions where the water and fertilizer conditions are better and sowing earlier, the yield of fresh grass per mu can reach about 10,000 kilograms. General fertility management level, per mu is also about 5000 kg.
Seeding ryegrass can be sowed in spring and autumn. The number of harvests in autumn sowing is higher and the total yield is higher. Spring sowing can prolong the harvesting period, and the grass is fresh, but the total production is low. The sowing date for autumn sowing is from early September to late November and spring sowing in early February.
Seed operation before sowing Muzhan bar fertilizer 1000 to 1500 kg. If there is no organic fertilizer such as pig bar, 25 to 30 kilograms of calcium magnesium phosphate fertilizer can be used as base fertilizer. After fertilization, plough the land to do the trick. The ryegrass seed is small, and it is required that the buckwheat noodles be flat and no large clods. The sowing method can be broadcast or broadcast, but it is better for management purposes. The amount of mu for use is about 1.5 kg. If there is little rain during the sowing period or the soil is drier, soaking with fresh water can be used for 2 to 4 hours in order to facilitate seedling emergence and increase the rate of seedling establishment.
Management of ryegrass seedlings should be timely tillage and weed control. After the flood season, the shading has been closed and weeding is no longer possible. After each harvest, a small amount of nitrogenous fertilizer should be supplemented to speed up regeneration and increase production. Tigers and earthworms should be taken seriously during the seedling period. If any, they are found to be controlled by “toxic silkworm†pesticides.
The height of the harvested ryegrass grass is about 30 cm. The sowing time, the number of times and the output are related to the fertilizer and water management conditions. In the early autumn, the seeds can be cut 1 or 2 times during the year, and the next spring can be cut about 4 times. If planted in October, if it is well managed, it will be cut once a year and cut two or three times after the year. Spring sowing, can be cut 3 times in early June. Farmers can arrange the sowing time reasonably according to the feeding condition of livestock and poultry.
Black Light Blue Lamps(BLB)
These lamps effciently emit ultraviolet rays at 315nm-400nm,which have strong photochemical fluorescent effects.they are special deep blue filter glass which absorb visible rays and transmits .there are two types of hosphor are used with radiation peak at 352nm and 368nm,respectvely.
Application:used for tests,insections,examinations,stage illumination in theaters and
nightc lub ,advertisements and sign boards.
We have T5,T8,T9,T10,T12 ,and can do 5w/7w/9w/11w/13w/18w/24w/36w/55w
Black Light Blue Lamps (BLB) have shape, structural, and electrical characteristics similar to general fluorescent lamps used for illumination. They also have similar lighting circuits.
Therefore, ballasts and glow starters used for general fluorescent lamps can be used for black light blue lamps (BLB) of this type.
1 Total amount of the ultraviolet rays between 300nm and 400nm.
2 When the ultraviolet ray output becomes 60% of the initial output (after 100 hours of lighting).
