preparation example Construction

[0037] The preparation method of the nutrient solution formula for sand-cultured wine grapes includes the preparation method of the irrigated nutrient solution formula from germination to the color change period, the preparation method of the irrigated nutrient solution formula from the color change period to the mature period, and the irrigated nutrient solution formula from the mature period to the leaf defoliation period. The preparation method, concrete steps are as follows:

[0038] First prepare three 10L containers A, B, and C. A stores calcium nitrate and potassium nitrate whose concentration is 500 times the concentration of the nutrient solution formula, and stores them at room temperature; B stores magnesium sulfate and phosphoric acid whose concentration is 500 times the concentration of the nutrient solution formula. Ammonium dihydrogen, store at room temperature; store C sodium ferric edetate, boric acid, manganese chloride, copper sulfate, zinc sulfate and molybd...

[0061] The inner diameter of the planting pot is 40cm, the inner diameter of the bottom is 28cm, the height is 34cm, the volume is 24L, and there are 6 holes with a diameter of 0.5cm in the bottom of the basin. Fill the basin with quartz sand and perlite with a particle size between 0.5 and 1mm washed with tap water, mix them at a volume ratio of 3:1, and select 5-year-olds with moderate growth and similar heights during the dormant period (before the wounding period). For the above wine grape plants, wash the plants with tap water, remove the soil and stains attached to the root surface, and transplant them into the prepared sand culture pots. In order to ensure ventilation and light, the distance between the pots should be greater than 10cm .

Abstract

The invention discloses a sand-cultured wine grape nutrient solution formula, preparation method and cultivation method. The formula includes calcium nitrate, potassium nitrate, magnesium sulfate, ammonium dihydrogen phosphate, sodium iron edetate, boric acid, manganese chloride, Copper sulfate, zinc sulfate and molybdic acid; the preparation method is that container A stores calcium nitrate and potassium nitrate with a concentration multiple of 500, B stores magnesium sulfate and ammonium dihydrogen phosphate with a concentration multiple of 500, and C stores ethylenediamine with a concentration multiple of 1000 Sodium ferric acid tetraphosphate, boric acid, manganese chloride, copper sulfate, zinc sulfate and molybdenum acid are obtained by diluting and mixing the inner solutions of A, B and C respectively with water; the cultivation method includes step 1 of preparing sand cultivation and planting potted wine grape plants, Step 2 is watering in sand cultivation, step 3 is controlling the cultivation environment, and step 4 is cultivation management. The invention adopts nutrient solution sand culture to provide controllable environmental conditions for the growth of wine grapes, has good ventilation and water permeability, avoids the occurrence of insect damage, does not grow weeds, and is more suitable for the growth of wine grapes.

Description

technical field [0001] The invention belongs to the technical field of sand-cultured wine grapes, and relates to a nutrient solution formula for sand-cultured wine grapes, a preparation method for the nutrient solution formula, and a method for cultivating sand-cultured wine grapes with the nutrient solution formula prepared by the above preparation method . Background technique [0002] Compared with table grapes, wine grapes pay more attention to grape quality rather than yield, especially fruit quality will affect the content and intensity of sensory-related phenolic substances such as anthocyanins and flavonols and volatile aroma substances in wine. However, during the growth process of wine grapes, excessive nitrogen application often occurs, excessive vegetative growth, dense and large leaf curtain layer, affecting ventilation and light transmission, resulting in green and late ripening of fruits, frequent occurrence of diseases and insect pests, threats to reproductiv...
