Development of greenhouse vegetable cultivation technology, can be said to be a trend, with the improvement of people's living standards, vegetables diversification requirements will further increase, vegetable greenhouses can compensate for the lack of seasonal vegetables, no doubt in the future of vegetable production will play an important role. Winter greenhouse vegetable fertilizer after planting mainly based, but in this season dressing unlike other seasons. The amount of fertilizer are different as winter arrives, the outside temperature is decreased, resulting in reduced greenhouse geothermal, for vegetables is concerned, the performance is reduced to the amount of vegetable leaf growth, photosynthesis and transpiration decreased root activity weakened, water decreased ability to absorb fat. This temperature, ground temperature is more suitable for spring and autumn vegetables grown significantly different. Therefore, in the winter, dressing, going to change a lot of watering, fertilizing practices. Spring and autumn vegetables are in a strong growth phase, dressing the aim of further promoting plant growth. Most winter vegetables to grow late, as a result of large amount of plant nutrients consumed too much, growing weaker, and even premature aging occurs, in this case, the main purpose is to enhance the fertilizer plant growth, promote swelling fruit, avoid root aging, leaf senescence, plant senescence. There are other types of fertilizer in spring and autumn, high temperature, ground temperature is high, the impact of general fertilizer flushes most obvious root vegetables. As the temperature in winter, the ground temperature is relatively low, coupled with general fertilizer dissolved in water will further reduce the water temperature, not only will lead to backlash Shi temperature drops, the root cause harm to vegetables, fertilizer and nutrient utilization is low, therefore, winter fertilizer, water soluble fertilizer should be full and functional as a top dressing fertilizer flagship fertilizer. 4.16 More information please visit the company's official website www.zgsgwsw.com
