苧麻是多年生作物,一到冬季地上部分枯萎死亡,地下部分的麻蔸仍在进行孕芽壮蔸等生命活动。维持这些活动,需要适宜的温、肥、水、气、热。这项工作抓好了,能延长苧麻宿根年代,促进苧麻生长发育,来年一般可增产苧麻30—45％。在管理上具体抓三点: 1、中耕除草。苧麻每年要收获3—4次,在此期间都未进行中耕除草,土壤板结,杂草较多。因此,冬季中耕可以清除杂草,疏松土壤,提高土壤保水保肥能1987年第5期力,同时还可切断部分伸向行间的“跑马根”,控制无效分株,增加有效分株数。中耕深度应视情况掌握在7—12厘米之间,品种系深根型、粘质土、行蔸距较大的宜深;浅根型品种、沙质土、行蔸距较小的宜浅。 2、合理施肥。冬肥既保温又供肥,常言说“冬肥一年,春肥一季”。冬肥在麻园中耕除草 Ramie is a perennial crop, one withered on the ground in winter to death, the underground part of the mulberry is still undergoing pregnancy and other vital activities. Maintaining these activities requires appropriate temperature, fat, water, gas and heat. This work is a good job, can extend the ramie root age, promote the growth of ramie, the following year generally increase ramie 30-45%. In management specifically grasp three points: 1, cultivating weeds. Ramie harvest 3-4 times a year, during which no cultivation and weeding, soil compaction, weeds more. Therefore, the cultivation of winter weeds can be cleared of weeds, loose soil and improve soil water conservation and fertility in 1987, the fifth period of force, but also cut off some of the lines stretched between the “runner root” to control invalid ramets and increase the number of effective ramets. Depth of cultivation should be grasped in 7-12 cm as the case may be, the species of deep root type, clay soil, the line spacing greater Yi should be deep; shallow root varieties, sandy soil, line spacing from the smaller should shallow. 2, a reasonable fertilization. Winter fertilizer both insulation and for fertilizer, often said that “winter fertilizer, spring season.” Winter fertilizer in Ma Yuan cultivation weeding
