How to get high yield of vegetables during high temperature period? Roots must be maintained
Beginning in June, the temperature in many areas has been getting higher and higher, and all parts of the country have begun to show a "hot, hot, hot" situation, as the temperature increases, convenient vegetable management will also be a special need It should be noted that the management is more difficult, so how can vegetables be produced at high temperatures? Several standardization measures are shared with you.
1. Pay attention to the maintenance of blades
During high temperature, the leaves have a large amount of transpiration, a faster photosynthesis rate, and a heavier load. Therefore, the leaves should be continuously maintained to ensure the best photosynthesis. Rejuvenating agents are sprayed once every 7-10 days to increase the resistance of the leaves and plants. Force has obvious effect. Adjust the dosage according to the growth of the plant. Before spraying, spray 200ml per sprayer (15kg) with rejuvenating agent. During the fruiting period, spray 350-500 ml per sprayer and insist on continuous spraying.
2. Reasonably regulate the growth
The main problem faced during the high temperature period is lengthy, so it should be reasonably regulated.
3. Do a good job of shading and cooling
The best choice for sunshade cooling is the sunshade net, because the sunshade net can be adjusted manually. Some spray mud or ink on the shed film, which reduces the light transmittance to a certain extent, which will cause the crop to grow long. Do not cover the sunshade net all day or several days in a row. Cover it at 9:30 in the morning and close it at 4:30 in the afternoon.
4. Use watering to reduce ground temperature
If the ground temperature is too high, it will damage the root system of the crop, resulting in poor crop growth. Then, when the ground temperature is too high, use frequent watering to cool down. It is best to choose evening watering in high temperature periods.
5. Rooting is more needed in the high temperature period
Everyone knows that the root system of crops must be maintained in winter, but root management can not be relaxed during high temperature periods. In the case of high ground temperature, many capillary roots will burn or die, so you must continue to maintain root systems to ensure high yields.

Fruit juice drinks is a beverage made of fruit juice products obtained by physical methods such as pressing, centrifugation and extraction. Fruit juice retains most of the nutrients in the fruit, such as vitamins, minerals, sugar and pectin in dietary fiber. Often drinking fruit juice can help digestion, moisten the intestines and supplement the lack of nutrients in the diet.
There are two kinds of fruit juice: pure fruit juice and compound fruit juice. As far as pure fruit juice is concerned, it can be divided into two types: one is to directly use the original juice, and the other is to dehydrate the freshly squeezed fruit juice first, and then add water to reduce it into concentrated fruit juice. Most pure fruit juices are concentrated. AGOLYN offers various flavors of honey tea, such as honey Citron tea etc.
