In this research paper, the discussion has been done on the geographic and environmental conditions for the production of wine grapes in China. There has been an analysis of the geographical conditions including the climate, the temperature, the soil and other factors such as diseases, pests and insects. In addition to this, the fertilizers used have been discussed. Further, these geographical conditions and other factors in China have been compared with that of France and New Zealand. After the comparison, it has been found that the condition for the production of wine grapes is much better in Frnace and New Zealand.
There are a number of pest problems which may impact the grape wine production. Though in China, there aren’t many phylloxera based pest problems. In addition to this, there are a few insects which can lead to the endangering of the grape production in some of the commercial vineyards. Some of the most important grape insects include the Comstock mealy bug (Pseudococcus comstocki Kuwanna), scale (Parthenolecanium cormi Borchs), grape leafhopper (Erythroneura apicalis Nawa), rape leaf beetle (Oides decempunctata Bilberg), grape erinose mite (Colomerus vitis Pagenstecher), and grape bunch mite (Brevipalpus lewisi McGregor), grape clear wing moth (Paranthrene regalis Butler) and grape borer (Xylotrechus pyrrhoderus Bates).
In France and New Zealand, there are many pests and insects which have been affecting the wine grapes from time to time. Some of the pests include the Phylloxera, airborne fungus, esca and American Bugs. In 2014, esca impacted the production of wine grapes to a large extent. It had infected around 13 % of wine grapes in France during those times. Because of the same, wine grapes of around €1 billion had been destroyed. Similarly, American Bugs infection had wiped out the France wine industry in 2015. Thereby, there has been different pests and insects from time to time which have impacted the wine grapes production in New Zealand and France.
