【摘要】 目的:研究覆膜方式对当归成药期产量构成因素的影响。方法:以白膜半覆盖、白膜全覆盖、黑膜半覆盖、黑膜全覆盖、膜侧栽培和全膜覆土6种不同覆膜方式与露地平作比较栽培当归进行试验研究。结果:当归出苗率、收获株数、单根鲜重及产量覆膜栽培处理中膜侧栽培处理最低,覆膜栽培处理均较露地平作栽培提高,白膜半覆盖当归单根鲜重最大,为42.95 g/株,产量最高达6 056.25 kg·hm-2,露地平作栽培最低,仅28.47 g/株和3 087.50 kg·hm-2,白膜半覆盖、白膜全覆盖、黑膜半覆盖、黑膜全覆盖、全膜覆土和膜侧栽培依次较对照露地平作增产96.15%,91.90%,89.27%,70.65%,58.10%,13.97%。结论:在杂草较多易发生草荒的地块用黑膜半覆盖和黑膜全覆盖栽培当归能节省除草用工,实现节本增效生产;杂草较少的地块用白膜半覆盖和白膜全覆盖栽培。更多还原

【Abstract】 Objective: To study the effections of Angelicae Sinensis Radix film mulching modes on the yield and component factors during the medicine formation period. Method: An experiment research was made to plant Angelicae Sinensis Radix by 6 different film mulching modes: half-covered with white film,full-covered with white film,half-covered with black film,full-covered with black film,the film side planting,and earthing the whole film planting,compared with open field cultivation. Result: Results indicated that among plastic film mulching cultivation modes,the film side cultivation was the lowest in the Angelicae Sinensis Radix emergence rate,number of plot harvested plants,single fresh root weight and yield. However,all of plastic film mulching cultivation treatments were better than that of open field cultivation. The fresh weight of single root of angelica was the heavest,42. 95 g /plants and yield was the highest up to 6 056. 25 kg·hm-2by using white film half covering mode while that was the lowest level by using open field cultivation,respectively,28. 47 g /plants and 3 087. 50kg·hm-2. Compared with CK,half-covered with white film,full-covered with white film,half-covered with black film,full-covered with black film,the film side planting,and earthing the whole film planting modes in turn was increased by 96. 15%,91. 90%,89. 27%,70. 65%,58. 10%,13. 97%. Conclusion: Recommended that cultivation modes of half-covered and full-covered with black film were used in more weeds areas to plant the Angelicae Sinensis Radix in order to save the weeding labor,achieve costs saving and increase the yield;cultivation modes of half-covered and full-covered with white film were used in less weeds areas.更多还原
