榛树花粉悬浊液各组分的筛选与优化

Screening and Optimization of Hazulnut Pollen Suspension

为研究推广榛树液体授粉技术,解决人工授粉用工量大、效率低的问题,以“达维”(84-254)花粉为材料,应用正交试验,通过测定花粉悬浊液中花粉浓度、花粉生活力,筛选最优榛树花粉悬浊液配方。结果表明,当花粉悬浊液中蔗糖、硼酸、黄原胶、氯化钙分别为150,0.1,0.4,0.3 g·kg^(-1)时,花粉悬浊液的稳定性与花粉活力最佳。最优的榛树花粉悬浊液配方为榛树应用无人机液体授粉提供了可行性,并可在一定程度上提高授粉效率。

In order to study and popularize liquid pollination technology of hazelnut,to solve the problem of large labor and low efficiency of artificial pollination.Pollen of Dawei(84-254)was used as material,the optimal formulation of pollen suspension of hazelnut was screened by orthogonal test through measuring the pollen concentration and pollen viability in pollen suspension.The results showed that when the concentration of sucrose,boric acid,xanthan gum and calcium chloride in pollen suspension was 150,0.1,0.4 and 0.3 g·kg^(-1),respectively,the stability and viability of pollen suspension were the best.The optimal formulation of hazelnut pollen suspension provided feasibility for the application of UAV(unmanned aerial vehicle)liquid pollination to hazelnut and improved pollination efficiency to a certain extent.
