摘要
利用泡底土、非耕作层土、草炭、落叶松干叶混锯末、牛粪水 5种材料做覆土盖种的试验结果表明 ,防治樟子松苗立枯病效果最好的是松干叶混锯末小区 ,其次是泡底土小区 ;防治红松苗立枯病效果最好的是泡底土小区 ,其次是草炭小区。同时 ,这几种覆土材料对苗木的苗高、地径生长都有一定的促进作用。
Five kinds of materials,sludge of pool,soil under cultivated layer,peat,sawdust mixed with dried needles of larch and water soaked with cow dung are used as seeds coverings in order to protect and control seedling damping-off of Scotch pine and Korean pine.The results of the experiment show that the plot with best effect for control damping-off of Scotch pine is the one with sawdust mixed with dried needles of larch and next is the one with sludge of pool;the plot with best effect for control damping-off of Korean pine is the one with sludge of pool and then the one with peat.In the meanwhile,the height and the collar of seedlings are also improved to a certain degree.
