Research On The Application Technic And Importing Breed Of P.pratensis L. In Daqing Area

The application of the grass for lawn dated back to the 80s ,the former breed is Poa peatensis L Wabash , which is imported from Canada . In the early 90s ,with the rapid development of the Garden industry, individual breed of the grass for lawn couldn' t satisfy the need of the Garden constructing . People began to import a great many greed of grass for lawn from the foreign country. Before leading to grow, because of lacking the understanding to the biology characteristic, adaptability of the each species with effectively on trial, the blindness ushers in, causing the application ineffective, resulting in much waste. The problem is even evidenced in Daqing city. Aim at big celebrate the region need urgently the good kind in solution breeds selectively actual, we proceeded the system research. First, pass to proceeds to synthesizes the comparison with analyze with the characteristics to the temperament of various turfgrass, the precocious the series of within turfgrass is not only have the strong and green advantage in anti-that period grow, but also the anti-cold is strong and bear the drought and bear the salt alkali, is a big celebrating the region the best and good a source. Drawing lessons from Peking, Shenyeng city the strand of Harbin city three northern cities leads experience that growing and breeding selectively precocious in lawn. We from three grounds of ushered in the precocious the species of in 23 lawns on after another, and as to it's biology characteristic with synthesize the sex form proceeded the system the research. Through three yearses of on trial, to lawn precocious each species of protects the seedling rate, cover a disease rate, anti-salt alkali and divide the dint etc. Index sign proceeded the inquisition, record with analyze. Pass the research detection, protect the seedling rate is to judge the species in the most important index sign in the region's adaptability. Protect the more stable species in rate in seedling, is strong to the ecosystem environment adaptability of the native low temperature, drought, salt alkali, the anti disease is too stronger, many for native ideal species. Whereas, protect the more unsteady species in rate in seedling, live the dint too weak, the disease harms too much, along with the increment of the lawn age, soil rate would the nasty play increase, species that the region eliminate much. Finally, the adoption synthesizes to beat to divide the method, sieving to out 3-5 breeds, which is suit for Daqing region. These breeds are anti-cold, anti-dry, anti-solt and alkali. They grows strongly, and is good breed. This solved the individual problem in Daqing city and many other problems in this city. Aim at the heavy celebrating the dry and little rain in region and evaporate to have great capacity at the same time, the resources of water is serious short of and actual, and the stanza water irrigates to divided by with the chemistry the practical technique in etc. In grass could not in production with protect management very very applied actual, aim at the sex ground proceeded with the stanza water irrigates to divided by the grass with chemistry for technical research in main application with inquiry into. Pass to use the and spray in protect management the waits the technical result in tiny enunciation, the tiny is better than to irrigate traditionally on the stanza water, not only save the precious the resources of water in large quantity, but also making lawn quality increased, having the vast development foreground. In good a heavily, the above chemistry in adoption divided by grass as the lord, matching with the machine divided by the grass, living creature divided by the grass synthesizes to divided by the miscellaneous technique, and put forward the ecosystem of the miscellaneous grass in control teach the seedling theories. Since grows the temperament according to the lawn with miscellaneous grass temperament and occurrence regulations, adoption ecology principle, proceed the cent step of the miscellaneous grass defend to divided by, not only for gr...
