Screening of high efficiency of pollen dispersant for liquid pollination of pear
Dispersants that efficiently disperse pollens can effectively realize the labor-saving preparation of liquid pollination of pear trees,and can solve the problem of low efficiency of liquid pollination of pear trees caused by insufficient pollen dispersion to a certain extent.In order to obtain a dispersant that can efficiently disperse pollens in the liquid pollination of pear trees,Huanghuali pollens purchased from a company in Qingd-ao,Shandong was used as the material.The pollens(10%,W/W),dispersant and diatomite matrix were mixed as wettable powder.Its wetting power and suspension rate were measured,and the pollen germination rate in the culture medium containing dispersant was also measured.The results showed that when the mass fractions of the dispersants sodium dodecyl sulfonate and sodium carboxymethyl cellulose in the pollen wettable powder was 1%and 1%,respectively,the dispersion and vitality of Huanghuali pollens could be mostly effec-tively achieved.The recommended pear pollen liquid pollination formula used in production was 10%sucrose+0.01%boric acid+0.03%calcium gluconate+0.04%xanthan gum+0.01%Sodium Lauryl Sulfate+0.01%sodium carboxymethylcellulose+0.1%pollens.
