At present, okra is cultivated in the north and south of China. Generally, the first sowing in the south is from April to early June, and it can be harvested in July-65438+10. The second harvest was in August, and it was not harvested until 165438+ 10. In the north, it is relatively late, and sowing usually begins from the end of April to the beginning of May. In some cold places, greenhouses or greenhouses are generally used to raise seedlings. If so, the sowing time can be advanced to March.
The whole growth period is about 120 days. As long as this time is arranged reasonably, the frost period can basically be avoided. Okra has strong adaptability, and most soil can be planted. In order to ensure the yield of okra, it is best to plant it in loam or sandy loam with deep soil layer, loose and fertile soil and good drainage.
Planting and maintenance of okra
Okra is suitable for growing in sunny environment. In the later period of maintenance, it is necessary to provide all-weather astigmatism to plants and water them once a day to keep the soil moist. Note that the leaves of okra are slender and there are many branches at the top, which makes it easy to be top-heavy. After discovery, a wooden frame should be built in time to reduce the bearing capacity of the trunk.
Okra has developed rhizome and strong absorption. When the plant height is 40 ~ 50 cm, apply 1 times fertilizer around the plant and loosen the soil. 1 mu After picking the first to second fruits, topdressing urea 10KG. In the middle and late stage of growth and development, in order to avoid premature senescence of leaves, 0.3% potassium dihydrogen phosphate aqueous solution/kloc-0 can be sprayed once every 5 ~ 7 days and continuously for 2 ~ 3 times.
