城市化的发展对城郊养殖场有巨大的影响。城市化环境下管理厩肥成为一个急需解决的问题。美国学者P.E.Cabor等人通过调查问卷的方式,研究了城市化环境下厩肥管理中的问题与对策。结果表明:交通问题显著制约运输厩肥;运输厩肥的最佳距离为5.03km。在厩肥使用受制约的地区,为了满足农艺和环境的要求,促进了养殖场与种植场间进行合作关系。伴随着城市化的发展,牲畜的饲养规模也在加大,很多大型养殖场开始有效地锁定土地,意味着大量的厩肥瞄准了有限的放置基地。但随着城市化的发展,在所估计的最大距离内,几乎没有作物种植地可用于放置厩肥。为了帮助养殖场在有限的基地上管理厩肥,厩肥中介不失是一个好办法,但是到目前,由于厩肥中介与农田保护方案不一致,还不能实施。此项研究,有利于调整养殖场的布局。
The development of urbanization has a huge impact on suburban farms. Management of manure in an urban environment has become an urgent problem to be solved. The American scholar P.E. Cabor et al investigated the problems and countermeasures of manure management under the urbanization environment by means of questionnaires. The results show that transportation problems significantly restrict the transportation of manure; the optimal distance for transporting manure is 5.03km. In areas where the use of manure is restricted, agri-culture and environmental requirements are met to promote cooperative relations between the farms and the farms. With the development of urbanization, the scale of livestock raising is also increasing. Many large-scale farms start to effectively lock the land, which means that a large amount of manure is aimed at a limited placement base. However, with the development of urbanization, there is little crop planted land for manure application within the estimated maximum distance. In order to help farms manage manure on a limited base, it is a good idea to use manure agencies, but so far they have not been implemented due to inconsistencies between manure agencies and farmland conservation programs. This study is conducive to adjusting the layout of farms.
