The selected land plot has a flat topography, good irrigated condition, groundwater content of 0.2% or less, neutral soil and high fertility, and a sandy loam soil that does not weigh heavily.
The nursery time is generally the most suitable for growing seedlings 1 to 2 days before and after “White Dewâ€. Precocious convulsions tend to occur prematurely, and production decreases when they are too late. After planting the whole plant, fill enough water. After the water seepage, mix the seed and fine sandy soil in a ratio of 1:10 to sow. After sowing, cover the fine soil and the soil thickness is about 1cm. After the soil is covered, apply phoxim granules to prevent the underground pests. . The amount of seed used for the seedbed was 3g/m2, and about 350 seedlings emerged. Seedlings, seedling height 4 ~ 5 cm when the seedlings, keep the seedlings from 3 to 4 cm.
Planting time is generally suitable for planting before and after late October (frost). Soil preparation Mushi organic fertilizer 5000 kg, 50 kg of diammonium phosphate, 50 kg of superphosphate, deep-flip 30 cm after fertilization, combined with soil spray fluhalin EC to control weeds, and phlogoxin granules to control underground pests. The seedlings were selected with a height of 20 to 25 cm and a stem diameter of 0.6 to 0.9 cm, with 4 to 5 leaves of seedlings. Seedlings are too large and can easily cause bolting and flowering. When the seedlings are too small, they can easily freeze to death when they pass winter.
After planting and returning to the green, watering immediately after management and planting, and water infiltration, timely cultivating. Pour frozen water (in mid-November) before freezing and cover the mulch. Do a good job of film protection in winter and found that the hole was blocked in time and strictly prevented freezing seedlings.
Prevention and control of pests and diseases 40% Dimethoate EC 800 times to prevent sub-leaf pests, with the amount of Bordeaux mixture control round onion purple spot, with 60% aluminum alginate 500 times plus a spreading agent to prevent downy mildew.
