How to fertilize grapes during the expansion?
In June, grape growth has entered the period of berry enlargement. Fertilizing work during fruit expansion is particularly important. During this period of management, water and fertilizer supply must be strengthened to increase grape yield and quality. Scientific fertilizer During the rapid expansion of grape fruit, excessive nitrogen is harmful, it can aggravate the occurrence of disease, but also make the fruit coloring rate decreased, cracking fruit increased. According to the physiological and nutritional characteristics of fruit enlargement period, organic and inorganic nutrients are combined, a large number of elements are combined with medium and trace elements, and underground roots are combined with the above-ground foliar spray to achieve the effect of enlargement and coloring. The need for nutrients during fruit enlargement increases yield and improves quality. Organic nutrient fertilizers can be dominated by amino acids in the early stage of swell, and can be dominated by humic acid or fulvic acid in the later stage. In the three elements of nitrogen, phosphorus, and potassium, potassium can account for 50% to 60% of the total, and phosphorus can account for 20% -30%, nitrogen can account for 10% -20% of the total, calcium can account for 10% -20%, while adding some trace elements of magnesium, zinc, boron, iron, copper, molybdenum and rare earth elements are also more important; Foliar spray can contain mainly potassium, and phosphorus fertilizer, calcium, magnesium leaf fertilizer. While using fertilization, increasing the number of bacterial fertilizers will add brilliance. In addition, recent studies have found that organic silicon can harmonize the balance between nitrogen and phosphorus, potassium, and other elements in plants, make plants grow steadily, prevent cracking and sunburn, increase fruit powder, and enhance plant disease resistance. Therefore, in young fruit During the expansion period, timely addition of silicon is also necessary. Timely irrigation The period of grape enlargement is the peak period of water demand. Watering must be timely. At this time, water shortage will seriously affect fruit swelling. To ensure adequate moisture, promote fruit enlargement. As long as it does not rain, pour it once every few days until the berries become soft and begin to colorize. After fertilizing, it should be filled with small water. In case of heavy rain, it should not be filled, and drainage should be done in time. In order to guarantee the quality of grapes, it is required to strictly control the irrigation within one month before harvest to prevent the quality from decreasing. Before the advent of heavy rain, special attention should be paid to the prevention of flooding. During the berry coloring period, stop watering to increase berry coloration and berry quality.
