Introduction of growth conditions and planting techniques of okra

Okra is a kind of vegetable with high nutritional value, which can be eaten with cold salad. The pods of okra are very similar to those of chili, but not spicy. Because okra is a green and healthy vegetable, the planting efficiency has been greatly improved in recent years, so everyone's enthusiasm for planting has also risen a little. Next, let's take a look at the key points of okra growth conditions and planting techniques.

1. Growth conditions of okra

1. Soil requirements

Okra does not have high requirements for soil, and it can grow in most of the soil. However, using poor soil, the yield of okra will decline, and the quality of okra pods will also be affected. Therefore, when choosing soil, we should try to choose sandy soil with fertile soil, strong air permeability and less diseases and insect pests.

2. Temperature requirement

Okra likes a warm environment and has a poor tolerance to low temperature, so it is not suitable to be planted in the north, and it is generally not recommended to plant okra in winter in the south. But okra has good heat resistance, as long as it reaches the best germination temperature and growth temperature, it generally will not affect its emergence, flowering and fruit.

3. Water demand

Okra has good drought tolerance and does not require much water, so we should be careful not to water too much, otherwise there will be stagnant water and rotten roots that will lead to okra overgrowth or death. Especially in the emergence stage of okra, too much water is very harmful to the roots of the seedlings. So specific watering should be based on the growth of okra and solar terms. Especially when okra is harvested, the soil must be kept moist so that its fruiting pods will not be affected.

2. Key points of planting techniques of okra

1. Do a good job of seedling production

The work of interseedling should be carried out according to the growth period of okra, mainly in two times, when the heart is broken and two or three true leaves grow.

2. Weeding and soil cultivation by ploughing

After the seedlings are unearthed or planted, the temperature is relatively low. In order to increase the ground temperature, the seedlings can be ploughed twice in a row. Ploughing again before the first flower blooms is convenient for squatting seedlings and conducive to root development. After flowering and fruiting, the growth is accelerated, and it is best to cultivate the soil after each watering and topdressing, which can effectively prevent the plant from lodging.

3. Matters needing attention during the growth period of okra

Okra has higher humidity requirements for air and soil during the growth period, so artificial sprinkler irrigation should be carried out within 20 days after sowing. Because the temperature of okra harvest is relatively high, it is in the summer high temperature season, so the demand for water is large, and the surface temperature is relatively high. Generally, watering should be done before 9 o'clock, and watering should be carried out after sunset in the afternoon to avoid watering roots under high temperature. We should also pay attention to the problem of drainage in the rainy season to prevent dead seedlings.

Light is a key factor in the normal growth of okra, there must be sufficient sunlight in order to blossom and grow as scheduled. If the light is not good for a long time, the color of okra leaves is light, the pod setting rate is not high, and the planting benefit is low. Therefore, when planting okra, we must control the density, so as not to affect the light of okra.

4. Topdressing

On the basis of sufficient base fertilizer, an appropriate amount of fertilizer can be added, not only nitrogen fertilizer. The frequency of fertilization is basically one fertilization after emergence, one fertilization after seedling fixing or planting, and one fertilization after flowering and fruiting. The number and amount of specific fertilization should be determined according to the growth of okra.
