Research On Selection And Cultivation Technique Of Forage Breeding Of Northwest Liaoning Sandy Steppe Area

In this paper, on the research of adaptive cultivation experiment on27kinds of alfalfa,25kinds of woody family forage,9kinds of leaf vegetables and3kinds of other legumes forage,and select projects such as phenophase, mowing frequency, mowing height, the number of gaps,fresh hay production, the number of branches the main branch,15cm like section of branchnumber, leaf number, the rate of regeneration, fall dormancy height, turn green performance asindicators. As a result, Bao Feng1, affmity, Gannon3and Defy4are suit for the northwestLiaoning cultivated alfalfa grassland areas. Sibiricus and Leymus, two kinds of woody familyforage.Russia leafy vegetable, one kind of fodder grass. Melilotus, one kind of other leguminousforage class. Meanwhile, this paper research on ephedra cultivation, seedling weed control,irrigation, mowing techniques and cold winter test methods of alfalfa and pasture. Study foundthat alfalfa cultivation technology to adapt is that ditching east west direction10cm, thick casing2.5cm, irrigation to resist cold, using herbicides acetochlor to weed control, mowing three times.Then it will increase production, but also to ensure the winter rate, ephedra cultivationtechniques to adapt to the roots should be in place to mow cut, and properly delayed mowingtime, increase the dry weight, the above studies selected grass varieties and cultivationtechnology, Liaoning Northwest sand grassland forage species introduction and cultivation andmanagement provides a theoretical basis and technical reference.
