2.1 技术简介

技术定义:

The Dyker system consists of a special trailer which enables a soil conserving way of cultivating potatoes by building dykes in-between the lanes.

2.2 技术的详细说明

说明:

The Dyker system consists of a new tractor trailer for cultivating potatoes. It is only available as a proto type in Switzerland and was established by Grimme from Germany. With this new technology the normal dams for potatoes are built but also small dams in-between the normal dams. The small dams can prevent soil erosion and financial losses during a heavy rainfall event and are therefore a new soil conservation method.

Purpose of the Technology: The aim of this technology is to prevent soil erosion by water on the field. Water flowing down the slope of a field can be stopped at the small dams and infiltrates through a hole in front of the small dam. The construction of the dams inbetween does not take another working step but can be done simultaneously to the normal dam building. This saves time and money. The special trailer portrayed here is the only one in Switzerland and is currently being tested before getting to the market.

Establishment / maintenance activities and inputs: For the Dyker system only the new tractor trailer is needed in addition to the common tractor and the potatoe machine. At the moment this trailer is not yet for sale and there is only one proto type for testing in whole Switzerland. After the test period Grimme enterprise will decide about the production and commercialization of the Dyker system.

Natural / human environment: The system is intended to prevent soil erosion during the cultivation process of potatoes. Dams running parallel to the gradient are mostly endangered by soil erosion during the first 4-8 weeks. Small dams in-between shall slow down runoff and help infiltrating the water into the soil and thereby protect the soil.

The problematic crop of potatoes can be prevented from soil erosion thanks to the Dyker system. How can they be sustained / enhanced? The system has to be on the market soon and to be sold at an appropriate price.

6.8 技术的弱点/缺点/风险及其克服方法

土地使用者认为的弱点/缺点/风险	如何克服它们？
The overhang of the machine when turning around requires high knowledge and time.	Good technical skills and experience with big, heavy machines are necessary to use the Dyker system correctly so that it is a soil conservating method.
Costs for the Dyker system are not yet published. They should not exceed USD 5000-6000$.	Costs should not go beyond the financial possibilities of a land user in order to support a great adoption of the system.

编制者或其他关键资源人员认为的弱点/缺点/风险	如何克服它们？
The additional weight of the trailer could lead to soil compaction.	Divide the weight equally, adapt tire pressure in order to minimize damage to the topsoil layer.
