摘要
本文通过对卓资县上高台林场坝底营林区的人工山杏林喷施不同浓度的B9和硼酸溶液,以喷施清水为ck,比较不同处理条件下山杏林的物候、成花和坐果状况,对山杏花期冻害的预防进行研究,结果表明:(1)不同浓度的B9溶液能够推迟山杏开花2d~4d,能有效避免晚霜危害,成花率较ck显著提高,但坐果率效果不显著。(2)不同浓度的硼酸溶液能不同程度的提高山杏的抗逆性,从而提高山杏的成花率和坐果率。(3)喷施硼酸溶液的山杏相对于喷施B9溶液山杏的坐果率更好。
Through using the different treatment of density B9 and the boric acid sprayed on the Shanggaotai tree farm dam bottom afforestation area's artificial Armeniaca sibirica(L.) Lam.forest spurts to Zhuozi County,what spurts executes the clear water is ck,Compares the phenology,blossoming rate and forming fruits of Armeniaca sibirica(L.) Lam.under the different treatment.The research of prevent the Armeniaca sibirica(L.) Lam.blossom time freeze injury,the results showed that :(1) The different treatment of density's B9 can postpone the Armeniaca sibirica(L.) Lam.to blossom about 2~4d and avoid the late frost harm effectively,blossoming rate is more remarkable than ck.but the Fruit setting rate effect is not remarkable.(2)The different treatment of density's boric acid can raise the Armeniaca sibirica(L.) Lam.resistance under the varying degree,thus raises the Armeniaca sibirica(L.) Lam.blossoming rate and Fruit setting rate.(3) The treatment of boric acid is better than that of B9 in Fruit setting rate.
