The latest course on techniques and methods of raising okra seedlings

Okra is a warm-loving plant native to India. It is mainly eaten as a vegetable and is mainly grown in southern China. It is not a common vegetable and has good economic benefits. Planting okra is mainly direct seeding and seedling transplanting, no matter which kind, in fact, it has to go through a seedling stage of cultivation, so seedling is a necessary process. Let's learn about the specific work of raising seedlings.

1. Direct seeding seedlings

1. Sowing time

Direct seeding is relatively common, generally sowing in spring, spring germination is relatively strong, but sowing must reach a certain temperature, when there is frost injury, you can not sow seeds, probably in March, when the temperature rises to 15 degrees, but the greenhouse can sow seeds one month in advance.

two。 Treatment and sowing

Seeds can be sowed after soaking and absorbing water, so as to meet the water content of germination, and carbendazim can also be used to soak the seeds, which can eliminate germs and reduce the incidence of disease in the seedling stage. The row spacing of sowing is 10 cm. Cover 1 to 2 centimeters of soil and sow according to the hole. Generally water the seeds before sowing to prevent the seeds from being washed away.

3. Cultivate

Before there is no break, it is necessary to water more, always moisturize, promote germination, spread plant ash on the soil surface after germination, can absorb moisture, reduce diseases, and ensure humidity at the same time. Long real leaves can reduce the amount of water, once every three to five days, grow to more than 4 real leaves can use some light fertilizer water to promote rooting. Pay attention to seedling diseases, the common is Fusarium wilt, as well as some aphids, ground tigers.

2. Transplanting seedlings

1. Easy to raise seedlings

Use the same specification seedling tray, sow one seed in a hole, use river sand and peat as culture medium, cover the seeds, and place them in a moist shallow water environment without watering. Sprouting is relatively fast, put in the greenhouse to keep warm. The seedlings can be raised in advance, and after budding, the nutrient solution can be prepared and applied, and the growth will be accelerated.

2. Maintenance

Replace the maintained shallow water layer, add the nutrient solution, and continue to use it after recycling treatment, and replenish the nutrient solution and water regularly. If there is a yellow leaf phenomenon may be too much water, environmental light is too weak, the temperature is too high, lack of nutrition and other reasons. Growth should be regulated at all times.

Okra seedling is mainly to ensure the budding rate, fast growth, no disease harm. Don't be short of fat. The most important point is to pay attention to the period of sowing and raising seedlings, which is decided according to environmental regulation.
