摘要
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%。
The reason of fruitless with flowering in grape to which palatability variation,yield decline due to Boron deficiency.Through doing experiment for 3 years,we proposed that during harvesting to spring branch after 15 d,or at bud to young fruit period spraying 1 times efficient boron with 150 g/667 m2 to promote fruit setting rate upto 50.8%～58.5%,yield to 74.4%～95.9%.
