Key points of okra field management
1. Clever application of top dressing: Okra has a long growth period, and its tender fruit harvest period can be as long as 100 days. Therefore, in addition to applying plantar fertilizer before planting, topdressing should be applied in time. That is, after transplanting live trees, the seedling fertilizer should be applied once, with 400g of Jiamei bonus per mu, and 400kg of clean water should be poured in according to the tree. After entering the flowering period, topdressing a flower-promoting fertilizer, mix 10-15kg of Jiamei profit per mu with about 1200kg of water, and apply it between rows. After entering the fruit picking period, apply 1-2 times of strong fruit fertilizer, add 15-20kg per mu of Jiamei profit to about 1500kg of water, and apply it between the rows. In addition, when it enters the flowering and fruit picking period, you can also use 800 times liquid Jiamei Cerebrospinum. After 4 pm on a cloudy or sunny day, spray it on the front and back of the leaves until the leaves are wet. In addition, the southern soil is generally deficient in boron, and attention should be paid to increasing the application of boron fertilizer or spraying Jiameijin boron on the leaves.
2. Drought prevention and stain removal: Although okra is a drought-tolerant and moisture-tolerant plant, it is necessary to prevent drought and remove stains in high-yield and efficient cultivation. Therefore, pay attention to keeping the soil moist, especially during the peak harvest period and high temperature and drought. If drought is found, it must be watered in time to improve the yield and quality of tender fruits; be afraid of waterlogging in the seedling stage, and pay attention to preventing waterlogging, especially In the rainy season, it is even more important to clear the ditch and drain it so that it will not be affected by stains or drought during the whole growth period, and will always be healthy and not cause premature aging.
3. Intertillage and weeding: After top-dressing, watering or rainy days, intertillage and weeding should be done in time to prevent soil compaction; combined with intertillage and clearing of ditch for root cultivation, to promote root elongation, make plants grow strong and prevent lodging. Cultivation, weeding, soil cultivation, etc. can be terminated after the ridge is closed.
4. Pruning and leaf picking: Many lateral buds will grow from the lower part of okra seedlings (especially dwarf plants). For densely planted plants with full seedlings, too many lateral branches will affect fruit setting. The lateral buds should be wiped off in time to avoid nutrient consumption and improve field ventilation and light transmission; if the seedlings are thinner, only some weak branches need to be cut. Leave stout ones to increase fruiting branches. After entering the fruit-bearing period, the plant leaves to emerge faster, and invalid old leaves and residual leaves should be removed in time to facilitate ventilation and light transmission. Okra roots are deep and stable, and generally there is no problem of lodging. However, in southern areas, after summer, heavy rains and typhoons are frequent, and there is also the risk of lodging and breaking. Wooden sticks or bamboo poles should be inserted and tied to the main stalk to prevent loss.
5. Pest control: okra has strong resistance and few pests; its leaves and petioles have bristles, which can reduce pests and diseases; it is cultivated in the new vegetable area, and pests are rarely found. However, attention should be paid to "prevention first, comprehensive control", and agricultural, biological, physical and ecological control methods should be adopted to control the occurrence of pests and diseases. When it is necessary to use chemical pesticides, it is necessary to be scientific and reasonable to ensure that the pesticide residues in its products are below the national standard and do not pollute the ecological environment.
