[planting method of okra] how to grow okra

Okra is an annual herb, the root is straight root, the main root is developed, deep into the soil. Stem erect, highly Lignified, cylindrical, 1-2 m high, with lateral branches, green or dark purple, coarsely hairy. Okra likes warmth and is resistant to heat and cold. The optimum temperature for seed germination, growth and development is 25 ℃ and 30 ℃. The optimum temperature for flowering and fruiting period is 26 ℃ and 28 mol. The monthly average temperature is lower than 17 mol. Let's take a specific look at what is the planting method of okra.

Planting method of okra

Sowing seeds

(1) the main varieties of edible sunflowers are: conventional species, three eyebrows, spark sunflower, spark black blockbuster and American sunflower, etc.; hybrids, imported Dika brand DK119, domestic DK119 and RH118, RH3148, RH3708, RH3138, beautiful sunflower 138and so on. The main varieties of oil sunflowers are: S33 (ao 33), S47, G101, Kws303, kws203, Kangdi 102 and so on.

(2) during the sowing time, sunflowers can generally be sown when the soil temperature of 10 square meters reaches 8-10 degrees Celsius for five consecutive days. Generally speaking, the suitable sowing time for conventional varieties in our county is late April. When the growth period of hybrid varieties is more than 105 days, the general sowing time is about May 10, and when the growth period is less than 105 days, the general sowing time is late May.

(3) sowing methods for sunflower planting, it is better to plant sunflower in a single plant, preferably in one piece, but it can also be planted on the ridge and the edge of the ditch. Generally, corn spot seeder is used to sow seeds, and hoes or shovels are also used to sow seeds on demand. The sowing depth is suitable for 3m / m 5m / m.

(4) seed treatment has caused serious underground pests in recent years, and seed treatment must be carried out before sowing. The specific method is as follows: spray and mix the seeds with 40% isofloxophos and two pairs of water 6-8 jin, sow the seeds for 6 hours, wait for the seeds to dry 70%, and then sow.

Field management

The main results are as follows: 1. Sunflower seedlings grow fast and develop early in the seedling stage. in order to prevent the seedlings from crowding and overgrowing, the seedlings are corresponding when there is a pair of true leaves in the seedlings. Then, the seedlings should be fixed when there are 2 pairs of true leaves. In places where diseases and insect pests are serious or vulnerable, the seedlings can be fixed later, but it should not be after the emergence of 3 pairs of true leaves at the latest.

2. Sunflower fields are generally hoed three times by ploughing and weeding. Weeding was carried out with inter-seedling for the first time, shovel and hoe with fixed seedling for the second time, and weeding was carried out before ridge closure for the third time. While ploughing, the soil should be cultivated to prevent lodging.

3. Watering sunflower is a drought-tolerant crop. Generally, there is no need for watering at the seedling stage, the irrigation time of the head water should be postponed appropriately, the head water should be watered before the budding stage of the sunflower, two water should be watered at the flowering stage, and three water should be watered at the filling stage, and the whole growth period should be watered three times. Late watering should pay attention to the wind, so as not to lodge. In addition, in case of continuous rain or continuous high temperature and drought, less watering should be appropriate and foliar spraying should be carried out at the same time. Special attention should be paid to the principle of "dry and wet" after sunflower blossoms.

4. Some sunflower varieties with branching and artificial pollination have the characteristic of branching. Once the branches appear, they will cause nutrient dispersion and affect the development of the disk of the main stem. Therefore, when the plant bifurcates, it should be knocked out in time.
