Grapes have always been one of the most beloved fruits, and their bright color, rich flesh and sweet taste have become the main selling points to attract consumers. However, in the process of grape cultivation, we often face a series of problems, such as slow expansion of grapes, poor fruit coloration, lack of sweetness, etc. How to scientifically manage the grape swelling period has become the key to solving these problems.
1. Arrange and thin the ears of the fruits
Ear preparation and ear thinning is an important step in the grape fruit expansion stage. Usually after fruit set or after flowering15
At 20 days, when the kernel is about the size of a soybean, it is necessary to prepare and thin the ears as soon as possible. At this time, we should remove the stunted, sick, deformed, and small-grained fruits in time, and the amount of seeds left per panicle should be controlled at 50
80, depending on the variety. This not only keeps the ears loose, neat and beautiful, but also accelerates the expansion and development of the grains.
2. Water and fertilizer management
The demand for water and fertilizer is large during the expansion period of young grape fruits, so it is necessary to carry out water and fertilizer management in a timely and scientific manner at this stage. Keeping the soil moisture sufficient and stable is the key, neither let the soil be too dry, nor let the soil be too waterlogged, otherwise it is easy to cause the young fruit to swell and be inhibited, or there are problems such as deformed fruit and cracked fruit.
3. Grape and fruit ear bagging management
Ear bagging management is a commonly used method to prevent pests and diseases from invading the ear, reduce drug residues, and improve the quality and aesthetics of grape fruit expansion. Through bagging management, the fruit ears can be effectively protected, the influence of the external environment on the fruit can be reduced, and the quality of the fruit can be improved.
Fourth, the end of the topping
After grape fruit set, in order to control the vigorous growth of new shoots and consume nutrients in time to supply the development of fruit ears, we need to carry out the operation of peripheral topping. This step helps to concentrate the nutrient supply and promote the healthy development of the ears.
The above is the precautions for the grape expansion period, through careful care and scientific management, it can not only promote the rapid expansion of grapes, but also ensure the expansion and development of the fruit. However, the sweetening and coloring phase of the grapes also requires our attention.
1. Grape coloring
There are many factors that can affect the sweetening and coloring of grapes, including improper fertilization, excessive irrigation, unsuitable temperature and light, and pests and diseases caused by soil problems. In the face of these factors, we need to adopt scientific management and reasonable fertilization strategies. In the fruit coloring stage of grapes, the nutrient ratio of organic potassium rich in humic acid and food-grade mineral nitrogen and potassium elements can promote the expansion and good coloring of the fruit, so that it can be marketed as soon as possible and prolong the shelf life of the fruit.
Second, change the soil and take root
Soil modification is an important soil management method, which can regulate soil acidity and alkalinity in both directions, increase soil organic matter, improve soil structure, and improve soil permeability and oxygen content by using products rich in mineral-derived humic acid, fulvic acid, phosphate-solubilizing bacteria and water-soluble organic matter. This helps to improve soil fertility, promotes the growth of crop roots, and in turn improves the quality of the fruit.
3. Stimulate crop growth
By using products that can quickly improve crop growth, such as products containing mineral elements and organic matter, the internal circulation of crops can be regulated, making the leaves greener, the roots more developed, and promoting the delivery of more nutrients to the yield formation site, improving the yield and quality of crops.
In general, during the expansion and coloring phases of grapes, scientific management and proper fertilization are crucial. Through attention to detail, scientific fertilization and timely management, we are able to effectively solve a variety of problems and guarantee the yield and quality of the grapes.
