The high temperature and raininess in summer and autumn are extremely detrimental to the growth of cucumbers. In many places, cucumbers grow poorly and produce low yields. Therefore, the following points should be noted when planting summer and autumn cucumbers:
1. Variety selection: When cultivated, varieties with heat resistance, resistance to pods, disease resistance, high yield and strong growth should be selected.
2. Appropriate sowing: Cucumber cultivation in summer and autumn can be broadcast live, 5 to 8 months can be sown. The later the sowing temperature of summer cucumber is, the higher the temperature is, and the greater the influence on the growth of plants is.
3. Strengthen flood control measures: The summer and autumn cucumber growth period is in the rainy season. Therefore, it is necessary to choose high-lying, energy-reserving irrigation and loose fertile lands for small high-row cultivation.
4. Increase fertilization material light watering: At the time of cultivation, the base fertilizer should not be too much, and the organic fertilizer should be fully decomposed. In the summer, topdressing should not be applied to dilute manure. After light rain, combine 5 to 8 kg of chemical fertilizer per acre with cultivator and apply water in a timely manner. After heavy rain, apply 15 kg of fertilizer to Mushi. In summer, there is more rainwater, and it is necessary to pay attention to draining the gully and pouring well water in time after the rainstorm. Autumn drought-prone areas timely irrigation, each time the amount of water to be small, can take the principle of small water pouring, to avoid flooding irrigation. Small seedlings should be dominated by water control, and the seedlings should be ploughed once after they are harvested. When they grow to 3-4 leaves, they should be ploughed once again to promote root development. When the weather turns cooler in autumn, the amount of watering should be reduced.
Summer cucumber grows fast, melons are easy to grow old and should be harvested early. Cucumber growth from fast to slow, should be timely harvest.
