葡萄花而不实,适口性变差,产量下降,多为缺硼所致。通过3年试验,提出了葡萄在当年收获后-春芽前15d随肥施硼1000g,或在现蕾期及幼果期各叶面喷洒1次高效硼,每次150g/667m2,可使葡萄坐果率提高50.8%～58.5%,产量提高74.4%～95.9%。 Grape and false, palatability worse, production decline, mostly due to lack of boron. After three years’ experiment, it was put forward that grapes could be fertilized with 1000g of boron fertilizer 15 days before the spring harvest, or spraying 150g / 667m2 of high efficient boron once at the budding stage and the young fruit stage, Fruit set rate increased by 50.8% ~ 58.5%, yield increased 74.4% ~ 95.9%.
