In fact, in the process of growth and development of vegetable cultivation, the ingenious spraying of household vinegar into vinegar solution sprayed vegetables can effectively control pest diseases and greatly increase the yield and quality of vegetables.
Why use vinegar to spray vegetables?
1. Vinegar contains more acetic acid and trace amounts of lactic acid, amino acids, carbohydrates, sugars, gums, proteins, and contains glycerin, aldehydes and various salts.
2. These substances can be directly absorbed and utilized by plants when sprayed on vegetables, which can accelerate the synthesis of chlorophyll and improve the photosynthetic efficiency.
3. Promote the metabolism of substances and energy in vegetables, and improve the ability of vegetables to absorb water and fertilizer and stress resistance.
4, making vegetables grow strong and vigorous, is conducive to the accumulation of dry matter, which produces a significant increase in production.
How to spray vegetables with vinegar?
1. Chinese cabbage is usually sprayed when the large and small plates are opened. It is sprayed once every 4-5 days, the concentration is 400 times, and even sprayed 2-3 times. The cabbage can make the heart fast, the heart is solid, and the yield is increased by 30 gold. And easy to store in winter is not easy to rot.
2, tomato is generally sprayed during flowering and fruiting, spray once every 7-10 days, concentration 300 times, continuous spraying 3-5 times, can increase production by 10% - 30%
3, peppers can be sprayed 1-2 days after planting, spray once every 5-7 days, concentration 400 times, continuous spraying 3-5 times, can increase the yield of 10% - 20%.
4, cucumbers are generally sprayed during flowering and fruiting, sprayed once every 10 days, concentration 300 times, continuous spraying 3-4 times, can increase stems, increase leaf area, increase the number of single plants 8æ², single melon weight gain 12%, malformed melon reduced by 17%, increased yield by about 15%.
5, onions and garlic are generally used before freezing in winter, continuous spraying twice 50 times vinegar solution, can greatly reduce the impact of freezing damage.
In addition, the general pathogens and viruses prefer an alkaline environment, and do not like an acidic environment. Since vinegar contains more acetic acid, it is said that vegetable vinegar can sterilize and inhibit the growth of bacteria and viruses.
What should I pay attention to when squirting?
1, to master the time of spraying, generally around 15 o'clock in the afternoon.
2, vinegar period: vegetable seedling period to flower bud period, spray once every 7 days, continuous spraying three times.
3, to master the concentration of spraying, vinegar concentration is generally in the range of 100-500 times.
4, low temperature in early spring, small evaporation: vinegar concentration in the range of 250-300 times.
5. From early summer to late autumn, the temperature is high and the evaporation is large: the concentration of vinegar is in the range of 300-500 times.
Precautions:
The vinegar solution can not be mixed with alkaline washing powder, alkaline pesticide, grass ash, etc., so as to avoid neutralization and failure of acid and alkali;
Spraying vinegar on a variety of vegetables can not only effectively prevent diseases, but also greatly increase the yield, which can save the amount of medicine and improve the quality of vegetables!
High Security Fence: This type of fence is designed to provide a high level of security for properties. It is made with strong materials and designed to be difficult to climb or break through.
Anti-Climb High Security Fence: This is a type of high security fence that is specifically designed to prevent climbing. It typically features a smooth surface or sharp edges that make it difficult for someone to gain a grip and climb over the fence.
Anti Climb 358 Security Fence: This is a type of anti-climb fence that is made with a specific mesh pattern known as 358. The pattern includes small openings that are too small for fingers to fit through, making it nearly impossible to climb. The number 358 refers to the measurements of the mesh pattern - 3 inches of horizontal space, 0.5 inches of vertical space, and a wire gauge of 8.
Curved 358 Welded Wire Mesh Fence: This is a variation of the 358 security fence that includes curved sections. The curves add an additional layer of security by making it even more difficult to climb over the fence. The fence is made by welding wire together in the 358 mesh pattern.
