Over-summer cucumber should be top-dressed
Summer temperatures are high and plants grow fast. The growth period of cucumber in summer is just under the high temperature and strong light conditions. In order to make it high quality and high yield, the water and fertilizer management in the field should be strengthened.
Throughout the summer, the cucumber grows rapidly and grows quickly. In addition to applying the base fertilizer, it is necessary to replenish the topdressing fertilizer, especially by adding phosphorus and potassium fertilizers, in order to make the pod grow vigorously and prevent premature growth and premature aging. After entering the melon period, there will be more watering and rainfall, and the soil nutrients will be easily lost. Therefore, more fertilizer and groundwater should be used. The watering time should be selected in the evening or in the morning and it should not be watered at noon.
In high-temperature and dry weather, watering is performed once every 1~2 days, and topdressing urea or high-nitrogen compound fertilizer (26-0-4) 20 kg per acre during the watering interval. In case of rain or heavy rain, it is necessary to drain water and prevent flooding. After the hot and rainy days, it is necessary to timely cool the well water. In order to prolong the melon period and increase the yield, the use of potassium dihydrogen phosphate 100g/water 50kg per acre for foliar spray, spray once every 3 to 5 days, can also be foliar spray multiple compound organic fertilizer, dilution 500 times, spray 3 times.

Steel Grating
The steel grating be welded to products . Normally, hot galvanizing will be carried out after end welding process. The range PH6 to PH12.5, a stable protective film will be formed on the zinc surface, the hot dipped galvanized steel grating has good anti-corrosive property. Of course, the steel grating also have other surface treatment, for example painted and powder coated .
Steel grating can be cutting to different kinds of shape as per your special needs.
Steel grating including flat grating, 'I' shape grating, serrated grating.
In generally , the steel grating be used as stair tread, platform, fence, trench cover, ceiling, etc.
The advantage of steel grating :
firm welding
smooth surface
high strength
