摘要
蒙阴桃产业是其主要的经济支柱之一,种植面积和产量均居全国县区第一。杂草是桃园的重要生物因子,对桃树生长影响很大。本试验采用“W”九点取样法和对角线五点取样法,对桃园杂草的种类、出土规律以及自然消长动态进行了调查。结果表明:蒙阴县桃园杂草共28种,隶属于12科,其中菊科杂草的发生种类最多,马唐、牛筋草、鸭跖草和鳢肠等发生的频度及密度较高;阔叶杂草全年有3个出土高峰,禾本科杂草全年有1个出土高峰;桃园总杂草数量从3月份开始保持增长状态,直到8月份达到最大峰值。
Peach industry is one of the main economic pillars of Mengyin County.Both planting area and output of peach ranked the first in the counties and districts of China.Weeds are important biological factors in peach orchards and have great impacts on the growth of peach trees.In this experiment,the"W"nine-point sampling method and the diagonal five-point sampling method were used to investigate the species,unearthing regularity and natural growth and decline dynamics of weeds in peach orchards.The results showed that there were 28 species of weeds in the peach orchards of Mengyin County,which belonged to 12 families.The species of Compositae were the most,and the number and density of crabgrass,calves,foxtail and thorns were higher.Broadleaf weeds had three unearthed peaks throughout the year,and gramineous weeds had one unearthed peak.The total weed quantity in peach orchards increased from March and peaked in August.
