提高山葡萄坐果率的研究

Study on Improving Fruit Setting Rate of Vitis amurensis Rupr

进行提高新品种"北冰红"及品系94-7-75、98-8-165、2001-6-135坐果率研究。试验结果表明:在初花期和盛花期各喷雾一次矮壮素1000mg/L+0.3%硼酸水溶液、0.3%硼酸水溶液、野生山葡萄雄株花粉25g+硼酸30g+尿素50g水溶液和0.3%硼酸水溶液+0.5%砂糖水溶液等试验处理均能显著提高坐果率,分别比对照(CK)提高11.3%、12.2%、14.1%和16.1%。其中,0.3%硼酸水溶液+0.5%砂糖水溶液坐果率最高,有利于农民增产增收,建议在生产中推广应用。

An experiment conducted for increasing fruit-setting of the new breed ＂BeiBingHong＂ and the new strains 94-7-75、 98-8-165、2001-6-135 indicated：PP333 1 000mg/L ＋ 0.3% boric acid aqueous solution,0.3% boric acid aqueous solution,male pollens of Vitis amurensis 25g＋0.3% boric acid＋0.5% urea aqueous solution and 0.3% boric acid＋0.5% sugar solution could increase the fruit setting rate significantly and increased respectively by 11.3%,12.2%,14.1% and 16.1% compared to the control.Effect of 0.3% boric acid ＋ 0.5% sugar solution was the best.The treatment would help to increase yield and was suggested to promote application in production.
