2.1 技术简介

技术定义:

A cropping system for maize which reduces the reworking of the soil to the stripes, in which the seeds are planted.

2.2 技术的详细说明

说明:

Maize strip tillage is a mixture between no tillage and conventional agriculture. The reworking of the soil greatly reduced. Instead of ploughing and harrowing a special rotary tiller including a grubber is being used. The working depht of the rotary tiller is 10-15cm, the grubber reaches to 20-25cm depht. The machine reworks the soil on stripes of 30cm width. This is where the seeds are planted. In between there are stripes of 45cm width, which are left untouched.
In Switzerland farms usually are small. A major part of the arable land is used to produce fodder. (For example maize, grain, fodder beet)
Usually maize strip tillage is being used to avoid soil erosion or for economical reasons. Compared to conventional agriculture several working steps can be saved. The reworking of the soil, manuring, seeding and applying of herbicides can be done at once.
Since the machine is expensive and a strong tractor is needed, farmers usually don’t buy it on their own. In most cases a contractor will be tasked to do this work. Of course this is not for free. But since several working step are saved, there is more time left to do other work (6.5h/ha).
The reduced reworking of the soil holds remarkable ecological advantages. Occurrence of erosion is very seldom, because the stripes covered by plant residual significantly reduce the speed of surface water. To increase this effect, the stripes are laid along the height countours, if possible. Since the soil structure is not disturbed in the stripes between the seeds, the risk of compaction is reduced there. For that reason maize strip tillage is often used before potatoes in a crop rotation. This is a crop that is very sensitive to soil compaction.
The technique brings along an ecological disadvantage, too. Before sowings the precedent crop needs to be treated with a total herbicide (glyphosat) to avoid unwanted competition. Only in wet areas, where there is enough water available it is possible to not use glyphosat. Also in long time studies, residues of glyphosat could not be detected in the soil. But if ever weeds will develop a resitance against it, that would certainly be a major problem.
The enhanced risk of crop loss is another disadvantage of the technology. In conventional agriculture the soil is left to dry for a few days after ploughing. maize strip tillage does not hold that possibility. If the conditions are wet, risk of crop failure can be a problem. However, if conditions are good (dry enough), both quality and crop yield are similar to conventional agriculture.

注释:

Crop yield is about the same as in conventional cropping systems. The cost to apply the technology are about $410 per ha. It takes about 2 working hours per ha. In addition the glyphosat needs to be applied, which accounts for $150 or 0.75h of work. The following worksteps are not needed anymore (working hours, costs when tasking a contractor excl. material): Ploughing (1.25h, $260), harrowing (1.25h, $180), conventional seeding (1h, $100), manuring (1h, $50), applying of herbicides (0.75h, $90). In total about $130 and 4 hours of work can be saved per ha. In some cantons Streifenfrässaat is also subsidised. In the canton of bern this accounts for $420 per ha and year for the first 5 years of appliance. The costs for manure, herbicides, seeds are not included since they are the same as in conventional agriculture.

4.8 影响成本的最重要因素

描述影响成本的最决定性因素:

The machine is very expensive. In addition a strong tractor is needed (ca. 150hp). Thats why most farmer task a contractor with the seeding. In this case no initial investment needs to be done. The machine in this case study is used for about 60ha per year. A bigger workload would be possible.

The number of worksteps is greatly reduced. Thats why money and time can be saved. How can they be sustained / enhanced? Since less work needs to be done, the farmer can concentrate on other activities to enhance income.
Soil structure is improved. Risk of compaction is reduced. How can they be sustained / enhanced? Still heavy machinery should not be used under wet conditions.
Soil erosion is reduced very much. How can they be sustained / enhanced? The technology applies for maize only. Other conservation techniques should be used for other crops.

编制者或其他关键资源人员认为的长处/优势/机会
Steeper hills can be cultivated without risking erosion. How can they be sustained / enhanced? the stripes should in general be laid along the contours.

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？
Risk of crop failure is enhanced if seeding under too wet conditions.	The time of seeding is critical and should be chosen carefully. If conditions are too wet, ploughing might be a better choice.
The machine is very expensive. Single farmers usually cannot afford it.	Cost can be shared with other parties or a contractor can be tasked.
In general a total herbicide must be applied before sowing.	The amount of glyphosat should be adapted to the number of weeds.

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？
Reworking of the soil is still intense.
A powerful tractor is needed. Fuel consumption is still high.
