基于WEB和FTP的广西农业气象移动短信业务平台研发

以WEB和FTP技术为依托建立了广西农业气象移动短信业务平台,并对农业气象短信编写、审查、上传到移动公司服务器、移动网关发送短信等相关技术进行了详细介绍。该系统采用4层架构,4层分别独立,提高系统的安全性、稳定性和可维护性。     

花吊丝竹组培快繁育苗技术研究

The rapid propagation technology of Dendrocalamus minor var. amoenus was studied by investigating the effects of some factors such as selection of explant, phytohormone, culture method etc. The results show that: The best month for explant collection of D. minor var. amoenus is May and June. The best position for explant collection is middle-upper part knot of semi-lignification branch. The clump shoot could be induced in medium with 3/4MS+BA 4 mg·L^-1+KT 1 mg·L^-1+CW 100 mL·L^-1. The optimal medium for subculture of D. minor var. amoenus is 3/4MS+BA 2 mg·L^-1+KT 1 mg·L^-1+CW 100 mL·L^-1. Liquid medium is beneficial for improving growth condition and proliferation rate of clump shoot. The medium 1/5MS+IBA 8 mg·L^-1+ NAA 4.5 mg·L^-1 + KT 0.1mg·L^-1 is a relative suitable rooting medium for D. minor var. amoenus, with the rooting method of synchronized treatment first and then rooting. The survival rate of seedlings could be higher than 90% in substrate of fine river sand∶peat soil=3∶ 1.     

福建山樱花组织培养试验

以半木质化枝条为外植体,探讨外植体消毒时间、植物生长调节剂对福建山樱花组培各阶段的影响,结果表明:外植体先用75%酒精消毒30 s,再使用0.1%HgCl溶液消毒5 min的消毒效果较好。较适宜的诱导培养基为:MS+6-BA 1.5mg·L-1+NAA 0.1 mg·L-1;较适宜的继代培养基为:3/2 MS+6-BA 1.0 mg·L-1+NAA 0.2 mg·L-1;较适宜的生根培养基为:1/3 MS+IBA 1.0 mg·L-1+NAA 0.2 mg·L-1,生根率达97.4%。生根苗移栽到泥炭土∶珍珠岩∶黄心土(6∶3∶1)的基质中成活率可达90%以上。
