[ ] cultivation
Biological characteristics of hi warm, sunny climate, Hardy, strong adaptability. In the soil deep, loose and fecund, good drainage arenaceous qualitative loam planted.
Cultivation techniques for seed reproduction. In March 3-4, but the yield and quality is poorer, often using autumn sowing, suitable sowing period varies from place to place, North China in late August to the early 9, bunch planting by spacing35cm ×(15-20) cm open hole, hole depth of 5-10cm, drill press spaced 35cm apart shallow trench, the seeds are uniformly sow, however the back cover of thin fine soil, pressure head. Seeding1hm2uses kind of quantity to11.25kg, a22.5kg15-20d, after sowing seedling.
Field management for second years after returning spring seedlings, seedling height of about 5cm started thinning, drill every leave 1strains, bunch planting per bunch5-8 strain. Second times every 10cm around1or thinning stay per bunch3-5 strain. For every 3after seedling in about 15cm into the final seedling, every12-15cm has1lines or1-3lines at a time per bunch, thinning, should combine weeding, wait for plant to grow up before sealing.
Prevention and control of diseases and pests infesting leaves, leaf blight, with 1:1:100Bordeaux mixture or polyoxin100-200flat spray. Huang Fengdie leaves, larvae, juvenile table parasite and bacteria (1g bacteria spore powder containing10000000000)500 times fluid or Bt emulsion liquid spray200-300 times, also artificial killing.
