摘要
为确定工业大麻的最佳播种期,在黑龙江省大庆市进行播种期(4月25日、5月5日、5月15日、5月25日)和品种(火麻一号、金刀15)二因素随机区组试验。结果表明:播种期改变工业大麻生育时期长短,对其物候期产生影响;火麻一号的原茎产量与分枝高、株高和雌雄比呈极显著正相关,金刀15的原茎产量与生育日数、保苗率和株高呈极显著正相关。火麻一号在5月5日播种时纤维产量最高,金刀15在4月25日播种时纤维产量最高,因此认为火麻一号的最佳播种时期在5月上旬,金刀15的最佳播种时期在4月下旬。株高是影响工业大麻原茎产量的主要农艺性状。
To optimize the sowing date,a field experiment with randomized block design was conducted at Daqing of Heilongjiang Province. The sowing dates were April 25,May 5,May 15 and May25. The two varieties were Huo Ma NO. 1 and Jin Dao NO. 15. Sowing dates should change growth stages and phenophases of industrial hemp. The stem yield of Huo Ma NO. 1 had a significant positive correlation with the branch height,plant height and female-male proportion. The stem yield of Jin Dao NO. 15 had a significant positive correlation with the plant height,growing period and survival rate of seedlings. The fiber yield of Huo Ma NO. 1 sowed on May 5 was the highest among different sowing dates. The fiber yield of Jin Dao NO. 15 sowed on April 25 was the highest among different sowing dates. Therefore,the beginning of May was suitable sowing period for Huo Ma NO. 1 and the end April was suitable sowing period for Jin Dao NO. 15. The plant height was the main agronomic trait that affected the stem yield of industrial hemp.
