杂草伴生时间对胡麻产量的影响
Effect of Weed Associated Time on Yield of Linseed
摘要
Abstract
Longya 10 as indication specie,comparation study is carried out in the field,the impact on associated time of weed on flax yield is observe,in order to seekthe optimum period of weeding in flax field. The associated time of weeds and linseed had a significant effect on yield of linseed,the longer of the associated time,the lower of the yield of linseed. The yield reduction rates of linseed are smaller when the associated time of weeds and linseed are 10 and 20 days,are 2.51% and 4.73%,respectively. The yield of linseed have a sudden drop when the associated time are 30 and 40 days,the yield reduction rates are 15.93% and 23.42%, respectively. The optimum stage of artificial or chemical weed control in linseed field is 20 days after emergence of linseed(plant height of linseed is 7 cm),weed control in the period can decrease the yield loss to a minimum.关键词
