杀灭土壤中线虫对小麦生长和吸收N、P的影响

盆栽条件下研究了施用杀线剂（克线磷，６７ｍｇ·ｋｇ－１干土）和干热（１０５℃，２ｈ）两种杀线措施对小麦生长和Ｎ、Ｐ养分吸收的影响．杀线剂对土壤中线虫的平均杀灭率约为８０％，干热处理的杀灭率为１００％．在杀线剂处理中，苗期至抽穗期小麦生物量、拔节期至成熟期植株含Ｎ量、全生育期植株吸Ｎ量以及抽穗和成熟期吸Ｐ量均显著低于对照．土壤干热处理后抽穗和成熟期小麦的生物量、含Ｎ量及Ｎ、Ｐ吸收量也比对照显著降低．两种杀线处理植株地上部生物量和Ｎ、Ｐ吸收量与相应处理全株变化趋势基本一致．但杀灭线虫对植株含Ｐ量影响较小．分析杀线虫后小麦生长和养分吸收受抑主要与土壤有机氮的矿化作用减弱。

A different approach for sterilization of liver hydatid cysts

TO THE EDITORMany different methods have been used in surgical treatment of liver hvdatid cysts. However, two methods have been frequently used recently： one is used to radically remove the cyst and the other is used to shrink the cyst cavity after treated with scolocidal agents. One of the most important principles for the treatment of hydatid cyst is to avoid the contact of fluid in the cavity with the adjacent tissues during cyst cavity contacts with scolek killers at certain time.
