果园生草制研究进展

果园生草是发达国家普遍采用的果园管理技术。果园生草能改良土壤理化性质,调节果园生态环境,影响果树植株生长发育,多年生草能提高果实产量和品质。果园生草体系中生草与果树存在竞争养分、水分的矛盾。在生草初期减弱了果树生长发育,影响了早期产量。其原因可能是体系中生草与果树根系互作,影响了养分、水分的运输和分配。目前,果园生草体系逐渐向与畜牧业、养殖业结合的复合生态系统发展,其发展前景广阔。

Research Progress on Orchard Sod Culture

Orchard sod culture is the technique popularly adopted by developed countries to manage the orchard, which can meliorate the physical and chemic characters of soil, adjust the environment of orchard, affect the growth of fruit trees and increase the yield and improve the quality of fruit. There is competition of nutrient and water between grass and fruit trees. In the early phase of sod culture., orchardgrass decrease trees'' growth and influence the earlier yield, which due to the orchardgrass influence the transportation and distributing of nutrient and water. Orchard sod culture system combined with livestock makes the orchard ecosystem comprehensive with widely foreground.
