2. SLM技术的说明
2.1 技术简介
技术定义:
Large-scale no-till grain production with permanent wheel tracks
common to all on-farm equipment.
2.2 技术的详细说明
说明:
This controlled traffic, no-till farming system (CT/NT) is practiced on a 1,900 ha farm on the broad, almost flat Jandowae Plains in semi-arid Queensland, Australia. Principal soil types are vertisols, with some poorer areas where the sand content is greater, and these have a tendency to hard-set and crust. Over the past five years, the farm owner has changed the farming system completely from conventional farming to no-till with controlled traffic. Controlled traffic means permanent uncropped wheel tracks or ‘tramlines’: all equipment has 2 metre axles. The total farm machinery comprises a tractor, a spray rig and two 11 meter zero-till planter/fertilizer units; one each for wheat and sorghum sowing. The tramlines were laid out two years ago by a contractor using Geographical Positioning System (GPS).
The main technical objective was to eliminate soil compaction. The CT/NT combination ensures the land -between the tramlines - remains in excellent condition. There has been no ploughing or tillage at all in those 5 years. He practices a three year rotation between winter wheat, summer sorghum and fallow, but the system is not fixed: it depends very much on soil moisture status and thus on the rainfall (opportunity cropping). Generally in summer about one third is in summer sorghum and in winter about one third in winter wheat, the rest of the land is
under fallow. The one-year fallow is maintained through the use of herbicides sprayed onto the undisturbed residue from the previous crop. The system is designed for rain capture - to build up soil moisture stores in the fallow periods for subsequent crops - and for disease control (to ‘spell’ the land). During the cropping cycle, the key to his effective weed control system is ‘to get in early’ and ‘actively chase weeds’ through judicious spraying. The farm is now free of the locally common persistent weed Erigeron annuus. In the five years his sorghum yields have risen from 3 to 7 tons per hectares. Over the last three years the soil has improved, becoming soft, friable and moist between his plant lines. Infiltration has improved a lot and soil structure is now excellent.
Tractor use and overall fuel consumption has decreased to less than one quarter of that under conventional tillage. Correspondingly the workload is hugely reduced: from four men required under the conventional system for an equivalent area, the farmer is the sole operator, very occasionally assisted by his son, and a paid contractor for harvesting. He is so satisfied with the CT/NT system that he is attempting to purchase a nearby property to extend the area that he can farm using his current machinery.

Comparison of costs between conventional tillage and no-till farming (CT/NT): (1) Labour costs are 4x less in CT/NT: 4 men used to work on the farm (conventional), now the farmer is alone – (plus contractors for harvesting). (2) Average annual diesel consumption: reduced from 108,333 litres (conventional) to 13,636 litres (no-till) which is 8 times less. (3) Costs of equipment to set up a CT/NT system (US$ 240,000) are 3 times less than that for conventional tillage equipment (US$ 700,000).
(4) For biocides he has to invest 5 times more in CT/NT. The conventional values are estimates.
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:
In average one third of the farm area is in crop and two thirds are fallow. This means that overall farming costs per
ha are reduced, since during fallow period activities are limited to spraying herbicides. Labour costs approximately US$ 160 per day. Machinery costs average out at US$ 20 per hour (diesel costs US$ 0.9 per litre). All the data comes from this single farmer. Purchase of equipment is not included in the table above.

6.7 该技术的优点/长处/机会
编制者或其他关键资源人员认为的长处/优势/机会 |
---|
Land that previously was un-farmable is now under crops. Site inspection shows initially poor land to be now in good condition (after only 5 years). The value of the land has increased How can they be sustained / enhanced? Farmers practising CT/NT can and are buying/leasing more land, which will improve the overall state of the land in Queensland. |
Farmers can manage much larger growing areas with less personnel and equipment. A single operator is well able to run a large arable farm on his own How can they be sustained / enhanced? Ditto. |
Cereal farming is now less prone to yield losses (and crop failure) in drought years – as there is better rainwater infiltration and water use efficiency with CT/NT How can they be sustained / enhanced? Continue with the system. |
He has all weeds under control (without need for tillage). |
6.8 技术的弱点/缺点/风险及其克服方法
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 contract harvester runs on 3 m wide axles, so the wheels run on the beds. However, there has only been one wet harvest in 5 years so the incidence of soil compaction from harvesting is negligible | This is not really seen as a problem. One solution would be to build a dedicated harvester (too expensive) or find a contractor with equipment that fitted the system. |
A conservative mentality towards conservation agriculture is constraining the adoption of the system by other farmers | Continue demonstrating and disseminating knowledge about benefits. |
