研究了太阳能杀雄的杀雄时期,杀雄温、湿度和杀雄效果。结果表明:同一品种在不同杀雄时期和温度下,不同品种在同一杀雄时期和温度下,杀雄效果都有明显的差异。但杀雄一般在40%的始花期,温度40℃以上,只需3~6 d杀雄效果就很理想。太阳能杀雄应根据品种熟期和特性,灵活制定适合自身的杀雄方案,使父母本花期相遇更好,达到理想的杀雄效果。太阳能杀雄为改善杂交技术及杂交种优势利用提供了新思路。
Studied the solar kill male kill the male, kill male temperature, humidity and killing male effect. The results showed that the killing effect of different varieties under the same killing rate and temperature was significantly different under the same killing rate and temperature. However, killing male is generally 40% of the initial flowering, the temperature above 40 ℃, only 3 ~ 6 d kill male effect is very good. Solar kill male should be based on species maturity and characteristics, flexibility to develop their own kill male program, so that the parents of the flowering meet better to achieve the desired effect of killing male. Solar kill male to provide new ideas for improving hybrid technology and the advantages of hybrids.
