红麻播后10—15天即可出苗.出苗后必须加强管理,才能获得较高的产量.1.早定苗,合理密植.红麻出苗后,要早间苗,3片真叶时定完苗.过去种麻是采收麻皮,现在是利用全秆造纸,因此可适当增加种植密度.从过去的1.2万株增加到1.8-2万株.一般行距50厘米,播幅加宽,株距6厘米,每亩留拐子苗2万株.2.及时施肥灌水.施足基肥、增施追肥对红麻的生物产量增加明显.一般每亩需施优质农肥3000—4000公斤,过磷酸钙10公斤,种肥硫酸铵5公斤.6月末至7月初红麻进入旺长期,需肥量特别大,要追施长秆肥,每亩应追施硫酸铵30公斤
Kenaf after sowing 10-15 days to emerge.After emergence must be strengthened management, in order to obtain higher yield.1.As early as fixed seedlings, close planting density.Kenaf emergence, the morning seedlings, 3 true leaves when the finished seedlings In the past, hemp was harvested from hemp, and now it is made from whole-stem paper, so planting densities can be appropriately increased, from 12,000 to 18,000 in the past, with a typical spacing of 50 cm, widening and spacing of 6 Cm, per mu acorn seedlings 20000. 2. Timely fertigation irrigation. Shizujifei, topdressing increased significantly increase the biological yield of kenaf. Generally need to apply high-quality agricultural fertilizer 3000-4000 kg per acre, superphosphate 10 kg , Kind of fertilizer ammonium sulfate 5 kg. From late June to early July kenaf into Mongolian long-term, the amount of fertilizer required to be particularly large, topdressing long stalk fertilizer, ammonium sulfate should be topdressing 30 kg per mu
