Open field cucumber needs reasonable fertilization management

For varieties cultivated in autumn cucumber, varieties with high heat resistance, disease resistance, strong growth potential and high yield should be selected. And the autumn cucumber can not be planted too late, because of the low temperature in the later period, affecting the knot.

The vegetative growth and reproductive growth of autumn cucumber are carried out at the same time. The time is short, the growth is fast, and the amount of fertilizer is large. The fertilization should master the principle of “basic fertilizer, light fertilizer, heavy fruit and fertilizer”, “less eating more meals, using fertilized fertilizer”. Generally, the base fertilizer should be applied with about 1500 kg of manure and urine, 50 kg of compound fertilizer or 50 kg of compound fertilizer plus 25 kg of ammonium bicarbonate. After the seedling stage is planted, 1:10 human excrement is used as the seedling fertilizer, and the fertilizer is added once every week, and the vines are inserted and vine. After entering the result period, the proportion of top dressing will be increased. If there is a condition, one melon can be collected and the fertilizer can be used. If it is raining, 5~7.5 kg of urea can be applied per mu. After entering the fruiting period, 0.3% potassium dihydrogen phosphate can be added 0.3%. Urea is used for top dressing.

Autumn cucumbers are both water and water. If improper irrigation, it will cause disease, leading to reduced yield of cucumber, leaving the park ahead of schedule. Therefore, irrigation should look at the sky, see the ground, and see the seedlings. According to the situation, the watering should be carried out in the morning or in the evening (cool, cool, cool, cool). Do not water or water at noon. It is best to use the ditch irrigation "horse water" to achieve small irrigation, diligent irrigation, with irrigation, no water, no water. After shrinking the soil, it is advisable to topdress in time to keep the soil moist.
