The Silicone Adjuvant is wetting and Penetrating Agent for the agrochemical.
Chemical name: Polyalkyleneoxide Modified Heptamethyltrisiloxane
Silicone adjuvant is a super-spreading surfactant based on a trisiloxane ethoxylate.
Spray Adjuvant lowers the surface tension of spray solutions, beyond that which is achievable with conventional adjuvants.
And,Silicone Surfactant promotes rapid uptake of agrochemicals into plants via stomatal infiltration.
spray adjuvant is nonionic in nature, making it useful with a broad range of agrochemical formulations.

Top dressing management
Overwintering and picking cucumbers lasts for 4 to 5 months. The total amount of fertilizer required must be large, but the amount of topdressing should not be too large. This is because the pumpkin root has stronger absorption capacity than cucumber roots, and has a wide range of fertilizer absorption. Therefore, it is necessary to increase the amount of fertilizer, but more fertilization can easily cause stems and leaves to grow. During a large part of winter, the growth of cucumber is not large, and it cannot be watered. When the amount of topdressing fertilizer is large, the concentration of the soil is too large and the concentration of the cucumber is too high.
Over-winter cucumbers are topdressed according to the following rules: After the first time, the melons are chased once, and the ammonium sulfate is 15 to 20 kg. In the low-temperature period, the fertilizer is usually recovered in 15 days or so, and the ammonium sulfate is 10 to 15 kg. In winter, we must pay special attention to doing a good job of foliar dressing, foliar spray fertilizer must not be too frequent, otherwise it will cause injury and damage; after the spring into the fruitful period, the dressing interval should be gradually shortened, and the amount of topdressing should be gradually increased. Large, each urea 15 to 20 kg per time; after the peak period of the melon, the plants began to age, topdressing and watering also have to be reduced, in order to promote stem and leaf nutrient return to the roots, so that the root system has been restored to extend the knot Melon period.
Air management
After a certain period of time after planting, the greenhouse shall be closed to ensure the humidity, raise the temperature, and promote seedling easing; after easing the seedlings, they shall be exhaled according to the need of adjusting the temperature and exchanging gas. However, as the weather gets colder, the air release will gradually decrease. To remove indoor humidity, harmful gases, and adjust the temperature in winter, it is also necessary to let out the wind. However, when the outside temperature is low in winter and cold wind blows directly onto the plants or when the amount of air is too large, it is easy for the cucumbers to suffer cold injury or even freeze damage. Therefore, the winter ventilation usually only opens the upper air outlet. During the air release, it is necessary to check the room temperature frequently to prevent the temperature from dropping too low.
As the weather in the spring gets warmer and the temperature becomes higher and higher, more and more indoor harmful gases will accumulate. In order to adjust the temperature and air exchange, the ventilation volume should be gradually increased. Ventilation in the spring must be combined with cucumber downy mildew. First of all, only from the height of the greenhouse (not less than 1.7 meters in principle) open air, can not put the end of the wind, the damaged mouth of the film must be repaired at any time, it is necessary to immediately close the air outlet when it rains, to prevent the entry of Arthrax spores indoor. In addition, the high temperature exceeding 32°C has the effect of inhibiting the spore germination of downy mildew, which is also a problem to be considered when releasing air. When the external night temperature is stable at 14 to 16°C, the air can be released overnight, but it is necessary to prevent rain. Into the room. The cucumber in the solar greenhouse has been growing under cover. Once the plastic film is peeled off, the production is finished.
Overwintering Cucumber Dressing Technology
Planting winter cucumbers is the planting pattern chosen by the majority of farmers in the Sunjiaji Street Office of Shouguang City, and it is also a major way for local vegetable farmers to increase their income. The author summarizes some suggestions for the experts on how to properly manage the over-wintering of cucumbers.
