阜南县位于黄淮海南部,紧靠淮河北岸,光、热、水资源十分丰富。年平均雨量为916.6毫米,在夏播作物生长期(6～9月)间降水量平均在360～400毫米,有效积温为2700℃,日照时数为918.3小时,基本上满足了麦茬红麻的生长需要。该县是麦茬红麻的主产区,面积较大,但单产低。为了改变当前麦茬红麻低产面貌,我们通过几年的试验和调查,总结出一套适合沿淮地区麦茬红麻高产栽培的综合技术。一、及时灭茬整地据调查,沿淮地区麦茬红麻传统种植方法为麦收后,免耕播种。而我们通过试验认为:麦收后,及早灭茬整地播种较免耕播种纤维产量增加6％。所以,沿淮地区在麦收后,有条件的地方,可采用小型手扶旋耕机及早进行灭茬整地;条件差的地方,要耕后耙碎,方可播种。
Funan County is located in the southern Huanghuaihai, Huaihe River, close to the north shore, light, heat, water is very rich. The annual average rainfall is 916.6 millimeters. During the summer sowing crop growing period (June-September), the average precipitation is 360-400 mm, the effective accumulated temperature is 2700 ℃ and the sunshine duration is 918.3 hours, which basically meets the requirement of kenaf Growth needs. The county is the main producing area of wheat stubble kenaf, a larger area, but yields low. In order to change the current low-yield wheat stubble kenaf appearance, we passed several years of testing and investigation, summed up a set of suitable for high-yield cultivation of kenaf in the Huaihe area comprehensive technology. First, timely stubble soil preparation According to the survey, along the Huaihe area of traditional method of planting kenaf malt after harvest, no-tillage sowing. However, we believe that after the wheat is harvested, the yield of early-stage stubble planting is 6% higher than the no-tillage sowing fiber. Therefore, the area along the Huaihe harvest, the conditional areas, the small hand-held rotary tillage machine can be used as early as stubble preparation; poor conditions, to harrow after tilling, before sowing.
