One kind of wine-grapes cultivation technique in the upper reaches of Minjiang River” was licensed with a national invention patent by the The State Intellectual Property Office to the scientists of Chengdu Institute of Biology, Chinese Academy of Sciences (CAS).
The upper reaches of the Minjiang River is an ethnic minorities areas, where the native social economic level is still underdeveloped. The dry river valley is an optimal climate resource for plantation especially for wine-grape cultivation. However the traditional pruning methods brought many problems such as unbalanced growth between vegetative and reproductive components of grapevine, lower set fruit rate, poor fruit quality epidemic and loose clusters.
The scientists of Chengdu Institute of Biology, CAS have studied the living habits of the wine-grapes transplanted in the upper reaches of Minjiang River for ten more years. They identified the underlying problem and invented a new kind of technique by pruning the lateral twigs of the wine-grapes in the native areas.
By use of this technique, the total leaf area of the vine can be controlled properly to avoid over-pruning the lateral twigs which leads to winter-bud germination and over-growth of pathogens and insects because of redundant branches and crowded space. This technique can save labor cost, improve the grape fruit quality and quantity, thus promoting the wine-grapes cultivation industry in the upper reaches of the Minjiang River.
