Grapes have low soil requirements, but for the normal growth and development of grapevines, it is best to use sandy loam or light loam with loose texture, good permeability,drainage, and fertility, ranging from slightly acidic to slightly alkaline,and a low density. During the planting process, maintain good soil structure by regularly deep plowing and shallow loosening to enhance soil aeration and water retention. Additionally, grapes have high water needs,especially during the growing season and fruit enlargement period. In seasons with abundant rainfall, timely drainage is necessary to prevent waterlogging and damage to the root system. Fertilization for grapes should follow the principle of"organic fertilizer as the mainstay,chemical fertilizer as the supplement." During the growing period,apply additional fertilizers as needed based on grape growth and soil fertility to meet the demands of different growth stages. Base fertilization primarily uses organic fertilizer, typically around 5000 kilograms per acre, which should be spread or applied in trenches, mixed evenly with the soil, and then the topsoil should be refilled.Grapes have a large growth volume throughout their entire life cycle, with over 80%of branches and leaves growing within just a few months. Mature grapevines have well-developed root systems, strong ability to transport nutrients and water through stems, and high branch growth and yield,making grapes a heavy-fertilizer crop that requires high water and nutrient management.
| Period | Phenological period | Main targets of prevention and control | Nutrient management | Remark |
December~February | period of dormancy | Various overwintering diseases and pests:black spot disease,downy mildew,anthracnose,white rot disease,mites,scale insects,winged moth | The mixture of sulfur and lime should be sprayed on the old vines and the main trunk | |
Mar | Tuber enlargement period(initial opening of scales) | Black spot disease and other bacteria | Spring garden cleaning is one of the key measures to prevent black spot disease | |
stages in germination | anthrachose of grape | |||
April | Germination-new shoot growth | Grain size is grape-like Gray mold,ear brown rot | 1. Apply 7.5mL/m2 of JINMAI-Green Sum®Seaweed essence solution every 7-10 days 2.If the weather is low,you can apply 1.5g/m2 of JINMAI-Cuikuo®Low temperature broken algae essence 3.Spray JINMAI®Green Cell Excitation Energy L-Amino peptide solution 1000 times on leaves | 1.Spray 1000 times of Youhua Yougu before flowering,and spray once after 15 days to improve flower and fruit setting. 2.Start to prevent gray mold after the beginning of flowering until the young fruit period.Pay attention to the nozzle of the spray when using the drug during flowering. |
Early to mid-May | Flowering-young fruit period | Gray mold,ear brown rot,downy mildew,beetle,winged leaf moth | 1Applying JINMAI-Baozhilin®Series 19-19-19+TE 1.5g/m2; 2Apply 7.5-15g/m2 for harvest energy+3mL/m2 for JINMAI-Yiweipu® Glucan Calcium 3Apply 800-1000 times of JINMAI-Blooming®on the leaf surface | 1.The vigorous growth of the giant grapevine ensures good flower and fruit protection.After flowering,use 10 ml of Guoguang Da Guo diluted in 34 kg of water to soak the flower clusters for flower and fruit protection;to promote fruit enlargement,after physiological fruit drop at 15-20 days post-flowering,spray 30 ml of 10.1%benomyl(Guoguang Daoling)per 15 kg of water on the fruit clusters 2.If the damage of winged moth is found,remove the insect branches immediately. 3.In order to prevent the disease of the fruit,the bagging time should be delayed,preferably about 35 days after flowering. |
End of May~June | Fruit hard core period-color change period | Crack-resistant fruit Downy mildew,anthracnose,June beetles,fruit shrinkage | 1Apply JINMAI®Green Cell Excaitation Energy Marine fish protein concentrate+JINMAI-Baozhilin®Series macronutrients 16-8-32+TE 15g/m2 2.Apply tJINMAI-Yiweipu®complex acid Glucan Calcium Boron 800-1000 times on the leaf surface | |
July | Transmutation~maturity | Crack-resistant fruit Downy mildew,anthracnose,white rot,red spider | 1.Apply JINMAI-Baozhilin®Series 16-8-32+TE 15g/m2 2.Foliar spraying of JINMAI-Thousands Red®800-1000 times+potassium dihydrogen phosphate 1000 times | 1.The bagged fruit should be unpacked and checked regularly,and the bag should be unpacked and sprayed in time if the disease is found. 2.Stop spraying 10-15 days before picking. 3.Use Luna's disease and fruit protection powder to make the grapes look good. |
August | maturation period | Coloring and sweetening Downy mildew,anthracnose,white rot,red spider | 1.Apply 800-1000 times of JINMAI-Thousands Red®on the leaf surface+Potassium dihydrogen phosphate 1000 times | Time of bag removal:In principle,bag removal should not be early.When picking fruit,bags should be cut together.If it is a continuous sunny day during the ripening period of grapes,bags should be removed in batches 3-5 days earlier according to the maturity degree.Bags should never be removed in one batch to avoid disease after bag removal in case of rain. |
September~November | After harvest(accumulation of vegetative growth) | downy mildew | 1Apply JINMAI Motive Power®7.5 mL/m2 2Apply 1000 times of JINMAI Yiweipu®Ca-Mg-B-Fe-Zn-Mn-Mo on the leaves | Spray the leaves to protect them and lay a good foundation for a good harvest next year. |
