Term for the conscious sowing and / or approval of suitable plants in the vineyard between the Rows of vines, This measure is part of the Organic viticulture at the biological respectively. Integrated crop protection almost mandatory. Greening protects erosion, favors the formation of humus, enriches the microbiological soil composition with organic nutrient, creates positive water competition with the vines and thus yield reduction, ensures better water storage and water discharge and thus optimal water balance, reduces nitrate leaching, causes less susceptibility to diseases such as chlorosis. fungal diseases. stem necrosis and Verrieseln, reduces the mineral fertilizer effort and creates food supply for beneficials like insects and birds.

Advantages and possible disadvantages

Last but not least, a weather-independent, more comfortable inspection is particularly useful with the vintage, as well as better driveability with automated vineyard maintenance. However, these advantages can only be achieved through the targeted use of the most suitable plants. Possible disadvantages are additional or excessive water consumption and higher evaporation (Evaporation) and thus water stress, insufficient vigor, inadequate nutrient supply especially with regard to nitrogen and reduction of the extract content in the grapes. The most important parameters for the implementation of a greening are the Weingartenboden, the annual Rainfall and the water Resources,

greening plants

Typical greening plants are different types of grass (Bermuda grass, panicle grass, fescue grass, ostrich grass, ryegrass), yellow mustard, caraway, alfalfa, lupine, mallow, clover, oil radish, phacelia, rapeseed, trespe, sweet peas, meadow button and cereals (barley, oats, rye, rye, rye, oats, rye) ). The plants have different effects, the respective selection has depending on soil type, desired effect and water balance. Various seed mixtures are offered in the trade in this regard. In dry soils, short-rooted plants are preferred in order not to remove too much moisture from the vines. If there is a tendency to waterlogging, deep-rooted plants with high water requirements, such as yellow mustard, are used.

With nitrogen-poor floors legumes (Legumes) sown, the nitrogen bind from the air and feed to the ground. However, the plants should never be “hosts” for the virus-transmitting ones nematodes represent. Either the pests should not be able to exist on them (non-hosts) or, at best, like the oil radish they should have a damaging influence (enemy plants). After a soil analysis by the EUF method and taking into account the water balance, the appropriate seed mix must be selected. To a certain extent, too weeds (Weeds) perform certain functions of targeted greening and are therefore used in one ecological Management partially tolerated.

greening species

The greening takes place either in the form of a dry seed or, for larger areas, by means of wet sowing (sprinkling greening). As a rule, only every second alley is greened. A necessary one fertilization then takes place in the open alley, because the nutrients reach the roots better and fertilizing the greenery would stimulate their growth too much. The perennial permanent greening (also mulch management) is mainly used for yield systems. Perennial (long-lived) plants are sown. Mowing has to be done several times during the growing season to limit the water consumption of the green plants. This should usually be done with a vegetation height of 15 to 20 centimeters. Depending on the amount of rainfall and green plants, as well as the location, this results in three to seven times a year.

The used Shredders Don't just mow the plants, but shred them and spread them out on the ground (mulching). Vine lying on the ground is also shredded by various vineyard work. By the rotting of the mulch too compost nutrients are added to the soil. A short-term greening (also green manuring or part-time greening) with annual, that is short-lived plants is mostly used in young plants. It serves to enrich the vineyard soil with nutrient humus as preparation for permanent greening, as well as when using legumes for the purpose of nitrogen supply. Sowing takes place in spring or early summer, rotting and nutrient supply only in the following year.
