This educational system (also MPCT, minimal pruning, non-pruning system, in German minimal cut) was developed at the research institute CSIRO developed in Australia in the 1990s. It is an extensive system with the aim of reducing the workload as much as possible. It also takes place at the espalier Application. All care measures in the vineyard are carried out almost exclusively by machine. Manual work is only necessary in exceptional cases. After the stick build-up and cone cutting, only the Kordonrichtung mechanically on short shoots cut back.
The system creates a completely different leaf roof structure and grape zone; the shoots are on the outer area of the large leaf wall. The high Eye numbers lead to a significantly lower one sprouting rate, the number of shoots is still larger. The growth of the shoots declines significantly, the grapes are lockerbeeriger and smaller, the berries have a smaller diameter. There is still no great experience. In addition to the greatly reduced effort, there are also advantages foliage care the lower susceptibility to Botrytis and wrong mildew as well as a rapid leaf surface development, disadvantages are greater tendency to water stress and coulure as well as a lot of small grapes.
After the changeover in the first year with high earnings In the following years there is a balance between the development of shoots and root mass. The Rebstock regulates itself, so to speak, which corresponds to the natural development of the vine. The vintage can only by means of grape harvesting respectively. The system is not suitable for all grape varieties. Very good for Bacchus. Dornfelder. Müller-Thurgau. Kerner. Riesling and Scheurebe, Only conditionally for Blaufränkisch. Blue Portuguese. Green Valtellina. Merlot. Pinot Noir. Pinot Meunier. Traminer and Zweigelt, See complete lists below training system (Systems) as well Weingarten Care (Activities).
