红麻产量的高低和纤维品质的好坏,与适时收获有着密切的关系。收获过早,产量低,纤维强力差;收获过晚,不仅影响后作播种季节,而且水温低,沤洗时间长,纤维品质差。因此,掌握好红麻的适时收获期,对提高产量和纤维精洗率具有重要作用。 红麻的适时收获与其生长日数有关。据我们在横岭、向花、新星大队调查测试,生长日数100天的纤维平均强力为20公斤,纤维强力不匀率31.2％,亩产306斤,表现性状较差;生长日数145天的纤维平均强力为
The level of kenaf yield and fiber quality is good or bad, and timely harvest has a close relationship. Early harvest, low yield, poor fiber strength; harvest too late, not only affects the sowing season, but the water temperature is low, wash a long time, poor fiber quality. Therefore, to grasp the timely harvest of kenaf has an important effect on the yield and the improvement of fiber rate. The timely harvest of kenaf is related to the number of days it grows. According to our investigation at Hengling and Hualing Brigade, the average fiber strength for 100 days of growth was 20 kg, the fiber unevenness rate was 31.2%, and the yield per mu was 306 pounds, showing poor performance. The number of days of growth of 145 days The average strength of
