本文根据现在通行的和将来可能产生的土地经营及耕种措施讨论新南威尔士南部实行的土壤保持耕作措施.首先提到在实行这种耕作制的田地上,对一个草田轮作的给定地点来说,决定土壤侵蚀强度的一个最重要因子是土地管理.我们通过研究新南威尔士南部的传统耕作制来说明土壤保持这个概念.由于传统耕作方法的安排常常与高强度暴雨的影响在时间上吻合,由此看来,与耕作相联系的主要侵蚀危害是经常发生的.有人提出在新南威尔士南部的任意一块可耕地管理策略中,土壤保持的最重要特征是与此有关的耕作量.这项工作的成效和缺点是与传统的土壤保持,土地管理措施,比如轮作中周期较长的牧草期,较短的休闲耕作地和等高耕作相联系的,在此将对这一点加以讨论.这一讨论强调了新的土壤保持土地管理措施的必要性.在目前可以采用的方法当中,我们在理论上主张,硬茬条播是控制侵蚀的最好方法,这一点将用Wagga Wagga研究中心的通行结果给以说明.但是,也有人指出在某些地方,排除耕作这一环节在农艺上是行不通的,因此,这些地方的耕作措施还需进一步研究.
This article discusses the soil conservation practices implemented in southern New South Wales based on current and future possible land management and cultivation practices.First, mention is made of the fact that for a given site of a rotation of grassland in a field where such farming is practiced, One of the most important factors that determine the intensity of soil erosion is land management and we illustrate the concept of soil conservation by studying traditional farming systems in southern New South Wales.Due to the fact that conventional farming practices often coincide in time with the effects of intense rainfall, In view of this, major erosion hazards associated with farming are frequent, and it was suggested that the most important feature of soil conservation in any of the arable land management strategies in southern New South Wales is the amount of farming associated with this The effectiveness and shortcomings of the work are linked to traditional soil conservation and land management practices, such as longer rotation periods, shorter fallow fields and contouring practices, as we will discuss here. A discussion underlined the need for new soil management practices for land conservation. Among the approaches currently available, Argues that stubble planting is the best way to control erosion, as illustrated by the prevailing results of the Wagga Wagga Research Center, but others point out that it is not agronomically feasible to exclude farming in some places Therefore, the cultivation measures in these areas need further study.
