亚热带超高产杂交桑品种配套技术及其在广西的推广应用

为了解决广西桑树品种老化和桑园产量低产等问题，广西蚕业技术推广总站根据广西的气候特点和生产实际，选育出超高产杂交桑品种桂桑优12和桂桑优62并研究出配套技术，该品种具有投产快、稳产高产、叶质优良等优点。至2012年，这两个品种在广西已经种植184．8万亩，占广西桑园面积的73．35％，占全国桑园面积的14．64％。通过对示范基地的测产试验，两个品种的平均亩桑产叶量能达到3218．33kg，亩桑平均养蚕4．35张，极大地提高了广西农民的桑园管理水平，对广西蚕业的发展起到了越来越大的推动作用。

Matching technology for subtropical super-high-yield hybrid mulberry variety and its extensive application in Guangxi

In order to solve the problems of mulberry variety maturing and low mulberry yield in Guangxi, the sericuhure technology popularization station of Guangxi bred the super-high-yield hybrid mulberry ＂No.12 of Guangxi excellent mulberry＂ and ＂No.62 of Guangxi excellent mulberry＂, and developed the matching technology according to the climate characteristics and actual production of Guangxi. It had many merits including quick production, stable-high-yield, and superior leaf quality. Up to 2012, there was 1.848 million mu of two new breeds in Guangxi, accounting for 73.35% of the mulberry field area in Guangxi, and accounting for 14.64% of the mutberry field area in the whole nation. In the yield test of demonstration base, average mulberry leaf yield per mu of the two breeds reached up to 3218.33 kg, which could breeding 4.35 sheets of silkworm with aver- age mulberry per mu. It greatly improves the management of mulberry field for Guangxi farmers, and plays a more and more important role in promoting the development of Guangxi serieuhure.
