近年来,国内外都很重视鲜食葡萄的花序整形和疏花疏果。花序整形和疏花疏果的目的在于提高果穗的整齐度,改善浆果的色、香、昧、形等指标,提高商品在市场上的竞争力,增加经济效益。(1)整花穗。为使果穗外形美观,果粒整齐,成熟一致,对座果率高的品种,要在花前3～5天,掐去花序前端1/4～1/5的穗尖,这称之谓掐穗尖。掐穗尖不仅达到疏除部分花营的目的,而且减少了果穗先端发生“水罐子病”的可能。为了达到同一目的,对一些有副穗的品种,也可以将其副穗剪去,称为去副穗。(2)疏花序。将结果枝上的弱小、畸形、过密和位置不当
In recent years, both at home and abroad attach great importance to the inflorescence grapes and thinning flowers thinning. The purpose of inflorescence shaping and thinning of flowers is to improve the uniformity of ears and improve the indexes of color, fragrance, ignorance and shape of berries, improve the competitiveness of commodities in the market and increase the economic benefits. (1) the whole flower spike. In order to make the appearance of the ear beautiful, tidy fruit, mature, for the high rate of varieties of fruit, 3 to 5 days before flowering, pinch to inflorescence front 1/4 ~ 1/5 of the spike, which is called pinch Spike tip. Pinch spike not only to achieve the purpose of sparse part of the flower business, but also reduce the occurrence of the ear “pot disease” possible. In order to achieve the same goal, for some species with spike, the spike can also be cut off and called the spike. (2) Flowering sequence. Will result in weak branches, deformities, over-dense and improper location
