We all know that some experienced farmers will have a set of tips for increasing production when planting fruits and vegetables. Many people have heard of the method that spraying vinegar can increase production, so can it? Vinegar contains a certain amount of acetic acid, amino acids, lactic acid, sugars, inorganic salts and other nutrients. These substances are sprayed on the leaf surface of fruit and vegetable plants, which are easy to be directly absorbed and utilized through the leaf pores, which is conducive to enhancing the photosynthesis of plants and accelerating the synthesis and accumulation of dry matter in plants, so as to significantly promote income growth. So what are the effects of fruit and vegetable planting and spraying vinegar? What are the precautions?
1、 Effect of spraying vinegar on vegetables
1. It has a certain role in pest control. The suitable growth and breeding environment for some aphids and diseases is generally neutral or alkaline, while vinegar is an acidic substance, which has a certain inhibitory effect on these diseases, so as to achieve the purpose of sterilization and insect control.
2. It can improve the yield and quality of fruits and vegetables. Amino acids, lactic acid, inorganic salts, glycerol and other components in vinegar can be directly absorbed and utilized by plants through leaf stomata, improve plant photosynthesis, enhance its stress resistance, promote the growth and development of fruits and vegetables, so as to improve the yield and quality of fruit trees.
2、 Vinegar spraying time
Generally speaking, for eggplant, cucumber, cabbage, pepper, pumpkin and other eggplant and melon vegetables and leaf vegetables, an appropriate amount of vinegar can be sprayed on the plants to promote production and increase income.
Eggplant and melon vegetables can be sprayed with edible vinegar once every 7 days from seedling setting to flower bud stage. A small amount of white sugar can be added to the vinegar (easy to attract pests), and can be sprayed continuously for 3-4 times. Generally speaking, such harmless vegetables can increase production by more than 30%.
Leafy vegetables can be continuously sprayed with 300 times of edible vinegar solution for 3-4 times from seedling planting to 15 days before harvest, which helps to quickly wrap the heart, wrap the porcelain solid, and store it. At the same time, it can increase the yield by about 30%.
3、 Precautions for spraying vinegar
1. Master the spraying time. The time of spraying vinegar on vegetables should be early rather than late. Generally, it is best to spray vinegar from seedling stage to flower bud stage. Spray a small amount for many times, continuously spray 3-4 times, with an interval of about 7 days. The specific time of spraying is preferably after 3 p.m. on a sunny day, which is conducive to being fully absorbed and utilized.
2. Control vinegar concentration. The vinegar concentration of spraying vegetables is generally 300-500 times. If it is a vegetable planted at the temperature of early spring, the concentration can be appropriately increased and controlled at 250-300 times the concentration of vinegar; In summer and autumn, it should be controlled at 300-500 times.
3. Pay attention to the spraying part. It is best to spray at the same time. It is not suitable to use the left in the past. Spray it evenly on the positive and negative sides of plant leaves.
The above is the function and method of spraying vinegar. Farmers can spray vinegar appropriately when planting fruits and vegetables to achieve the purpose of increasing production. However, we must master the concentration of vinegar, spraying time and position, and pay attention to the above matters to avoid adverse effects caused by poor operation.
