苎麻的冬培是保证常年高产稳产的关键措施。包括深中耕、重施肥和培土三个内容。冬培时间在小雪到大雪之间,过早因气温高,幼芽出土消耗养分多;过迟则易遭冻害。 (一)深中耕。第一年经过两次收麻后土壤板结,杂草较多,土壤养分缺少。深中耕后可清除杂草,疏松土壤,增加保水保肥及供肥能力。还可提高土壤硝态氮41.6%、速效磷25%、速效钾14.3%,促使壮蔸孕芽,根群发达,头麻增产显著。深3～5寸为宜,以不伤根为原则。 (二)重施肥。结合中耕进行深施肥,深施比表施增产18%左右。肥料以有机肥为主,配合一定的氮磷化肥。一般亩施饼肥100斤,粪水30担以上,过 Winter ramie cultivation is to ensure that the perennial high yield and stability of the key measures. Including deep plowing, fertilization and earth three elements. Winter training time between the snow to heavy snow, premature due to high temperatures, young buds unearthed more nutrients; late is vulnerable to frost damage. (A) deep plowing. After two harvests in the first year, soil compaction, weeds more soil nutrients lacking. After deep plowing weeds can be cleared, loose soil, increase water and fertilizer and fertilizer supply capacity. It can also increase soil nitrate nitrogen 41.6%, available phosphorus 25%, available potassium 14.3%, prompting Zhuangzao germination, root group developed, head Ma yield significantly. Deep 3 to 5 inches is appropriate to not hurt the root principle. (B) heavy fertilization. Combined with cultivation for deep fertilization, the application rate of deep application of about 18% yield increase. Fertilizer to organic fertilizer, with a certain amount of nitrogen and phosphorus fertilizer. General mu Shi cake 100 pounds, 30 dan manure above, too
