Fertilizer-requiring cucumbers should not be deficient in phosphorus throughout their growth period, especially after 20 to 40 days after sowing. The demand for potassium in the middle and late growth stages is large, but the effect of potassium deficiency on the yield in the early stage is much greater than that in the later stage. When the silicon is severely deficient, the leaves gradually wither from the lower part of the main stem, and the pollen fertility is low. For every 1000 kilograms of cucumber produced, 2.8~3.2 kg of nitrogen, 0.8~1.8 kg of phosphorus pentoxide, 3.0~4.4 kg of potassium oxide, 5.0~5.9 kg of calcium oxide and 0.8~1.2 kg of magnesium oxide.
The soil should be selected from humus loam which is rich in organic matter, has good gas permeability and can retain water and drainage. The pH value is 6.5, and the relative humidity of the soil is suitable.
85%~90%.
For nutrient soil preparation, the vegetable garden soil that has not been planted with cucurbit crops within 2~3 years is used, and the organic fertilizer should be fully cooked.
PC Wire
PC wire is used in major construction projects as a means of increasing the strength of cast concrete components, ranging from railway track sleepers, ground stabilizing piles, floor beams and pipe systems. The process involves the continuous heating and stretching of a cold drawn high-carbon steel wire to produce a finished product with a much improved yield stress and greatly reduced load relaxation.
