Okra cultivation conditions

1. Temperature okra likes warmth, is afraid of cold, and has strong heat resistance. When the air temperature is 13 ℃ and the ground temperature is about 15 ℃, the seeds can germinate. However, the optimum temperature for seed germination and growth period was 25-30 ℃. When the monthly average temperature is lower than 17 ℃, the flowering and fruiting is affected, while when the night temperature is below 14 ℃, the growth is slow, the plant is short, the leaf is narrow, the flowering is less, and the flower drop is more. 26-28 ℃ has many blossoms at suitable temperature, high fruit setting rate, rapid fruit development, high yield and good quality.

two。 Moisture okra is resistant to drought and moisture, but not to waterlogging. The excessive soil moisture during the germination period is easy to induce seedling blight. During the fruiting period, the soil should always be kept moist because of the drought, poor plant growth and poor quality.

3. Okra is particularly sensitive to light conditions, requiring long light time and sufficient light. Sunny land should be selected, ventilation should be strengthened, and reasonable close planting should be paid attention to so as not to shade each other and affect ventilation and light transmission.

4. Soil nutrition okra has wide adaptability to soil and does not choose soil fertility, but it is more suitable for loam or sandy loam with deep soil layer, loose and fertile soil and good drainage. Nitrogen is the main fertilizer in the early stage of growth, and more phosphorus and potassium fertilizer is needed in the middle and later stage. However, if there is too much nitrogen fertilizer, the plant is easy to grow, the flowering and fruiting is delayed, and the node position of fruit setting is increased; insufficient nitrogen fertilizer and poor plant growth affect flowering and fruit setting.
