How do you manage autumn radish planting? Please advise
Radish planting can be managed by referring to the following methods:
1. Thin and set seedlings in time. When the seedlings grow until the cotyledons are fully expanded, carry out the first thinning; when they grow to 3 true leaves, carry out the second thinning; when they grow to 4 true leaves, carry out the final thinning, after which the seedlings can be set. The planting density is 800 plants per mu; the planting density for large varieties can be appropriately thinner.
2. Watering. During the peak leaf growth period, generally do not water unless the soil is dry; water only when the soil turns white. After entering the root-setting stage, sufficient water should be supplied, and watering should stop one week before harvest. In rainy seasons, pay attention to timely drainage.
3. Fertilizing. After setting the seedlings, carry out the first topdressing, applying 10-15 kg of ammonium sulfate per mu; during the rosette stage, carry out the second topdressing, applying 10-15 kg of ternary compound fertilizer per mu. During the peak growth period of the fleshy root, ternary compound fertilizer should be applied as topdressing to prevent premature leaf senescence and promote fleshy root growth. In addition, during the fleshy root swelling period, a 0.3% borax solution should also be sprayed on the leaves to promote its growth.
4. From the seedling stage onward, 40% dimethoate 800-1000 times solution, 20% methomyl 1500 to 2000 times solution, or 2.5% aphid-whitefly-lice EC 3000 times solution can be sprayed to control aphids, striped flea beetles, cabbage caterpillars, etc. In the later period, spray 75% chlorothalonil 600 times solution or 65% zineb 500 times solution to control downy mildew; spray 50% zineb 800 times solution, 47% kasugamycin-copper 500 times solution, or 50% copper hydroxide 500 times solution to control soft rot.
