不同除草方式对苹果苗木生长的影响

Effects of Different Weeding Methods on Growth of Apple Seedlings

苗圃地极易滋生杂草,除草不当会阻碍苗木的正常生长发育,选择适宜的除草方式尤为重要,以苗木‘宫藤富士/G935’为试验材料,研究不同除草方式对苹果苗木生长的影响,为苗圃地绿色经济发展提供理论依据。结果表明:在苗木株高方面,地布防草显著高于除草剂除草与人工除草为166.07 cm。不同除草方式对侧枝也有影响,表现为地布防草与除草剂除草显著提高了长枝的占比,分别为56.51%与52.11%,而人工除草的苗木以中枝为主,占52.11%。地布防草有效提高了有效分枝粗度与分枝角度,分别达到了3.96 mm与62.86度。此外,地布防草较人工除草每年每667 m^(2)节约除草成本约为150元。总之,地布防草不仅提高了苹果苗木的生长质量,还能节约成本,可在苗木繁育中大力推广应用。

The presence of weeds in nursery soil can impede the normal growth of seedlings.Improper weed removal could hinder the normal growth of nursery,therefore,it is important to choose appropriate weed removal methods.In this study,the nursery'Miyato Fuji/G935'was used as the test material to investigate the effects of different weed removal methods on the growth of apple seedlings,the aim is to provide a theoretical basis for the sustainable development of nursery practices.The results showed that ground cloth weeding was significantly higher than that of chemical and artificial weeding,with seedling height reaching 166.07 cm.Different weeding methods also had different effects on lateral branches,ground cloth weeding and chemical weeding resulted in a higher proportion of long branches(56.51% and 52.11%,respectively),while manual weeding led to medium branches(52.11%).Ground cloth weeding effectively improved the effective branch thickness and branch angle,reaching 3.96mm and 62.86°,respectively.In addition,compared with artificial weeding,the cost of weeding was about 150 yuan per 667 m^(2) per year.In conclusion,the ground cloth weeding not only improves the growth quality of apple seedlings,but also reduces costs,which can be a promising method for widespread use in seedling cultivation.
