1.种子处理,苗床消毒:用50～55℃的温水浸种15分钟,再在冷水中浸泡3～4小时,捞出种后用湿沙布和干净湿毛巾包好放于瓦盆内,保持25～28℃的温度,每隔8小时用温水冲一次,一般24小时后就可发芽播种。每平方米苗床用10克64％的杀毒矾或58%的瑞锰锌拌细砂撒入苗床消毒,下垫上盖,对苗期病害防效达95%,子叶肥大,苗茎基比对照苗宽0.15厘米,幼苗生长健壮。 2.适时播种,培育壮苗:一般播种节令在n月中旬至12月上旬,每平方米苗床播种15克左右,如果采用直播,每亩播种150~250克,播后用薄膜覆盖,以防低温冷害。
1. Seed treatment, seedbed disinfection: soaked with warm water at 50 ~ 55 ℃ for 15 minutes, then soaked in cold water for 3 to 4 hours, remove the seed with wet sand cloth and clean wet towel wrapped in the tile basin, keep 25 ~ 28 ℃ temperature, every 8 hours with a warm red, generally 24 hours after germination sowing. Per square meter of seedbed with 10 grams of 64% of anti-virus alum or 58% of Ruimuzha mixed sand thrown into the seedbed disinfection, mats under the cover of the seedling disease control effect of up to 95% cotyledons hypertrophy seedling base than the control seedlings 0.15 cm wide, seedlings grow robust. 2. timely sowing, nurturing strong seedlings: General sowing season in mid-November to early December, planting seedbed per square meter of about 15 grams, if the use of direct seeding, planting 150-250 grams per mu, after sowing with a thin film to prevent Cold damage.
