The method of planting the radish is as follows:
1. Timing of cultivation
Spring: february-april, suitable for the area north of the yangtze, 25-60 days。
Autumn broadcasts: warm areas in the north from late july to early august; cold areas in the north-east and north-west in mid-july。
2. Landing and landscape
Soil selection: the soil is deep, estranged and fertile and well drained。
(b) twirling: deep tilling of more than 30 cm, removal of miscellaneous items, high hyena, 15-20 cm high and 1-1. 5 m wide。
Sowing
Seed treatment: three to four hours of warm water impregnation to promote germination。
Sowing method
Diffusion: 25-30 cm long and 1-1. 5 cm deep in ditches, evenly spreads of seeds and dust。
Caucasian: 2-3 seeds per den, 30 x 40 cm。
Seed density: about 500 grams per acre。
4. Field management
Sapling
The first sapling: two saplings were uprooted。
Second sapling: 4-5 saplings with one strong sprout per den。
Weeding in chinese: tilling in time to prevent grassland, so that it is shallow and the roots are avoided。
5. Watering
Shrimp period: soil moist and drought prevention。
(c) large-scale expansion of the meat root: increase the quantity of water, keep the soil dry and wet, and prevent cracks。
6. Following fat
Fattening of seedlings: 10-15 kg/acre of urea after seeding。
Bountiful root fattening: 30-40 kg/acre complex fertilisation at the beginning of the expansion and potassium phosphate sprayed on the leaves。
7. Pest management
Diseases
Black corruption: prevention with agrococin spray。
Frost: prevention with dubunk。
Pests
Aphids: prevention with aphids spray。
Vegetable larvae, moths: control by chlorflammide spray。
8. Harvest
Time: 75-90 days after sowing, when the root of the flesh expands。
Method: carefully extract, avoid damage, remove soil and leaves and leave a small amount of leaves。
The above approach can effectively improve the production and quality of long radish。
